+# Contributing to Super Graph
+
+Super Graph is a very approchable code-base and a project that is easy for almost
+anyone with basic GO knowledge to start contributing to. It is also a young project
+so a lot of high value work is there for the taking.
+
+Even the GraphQL to SQL compiler that is at the heart of Super Graph is essentially a text book compiler with clean and easy to read code. The data structures used by the lexer, parser and sql generator are easy to understand and modify. 
+
+Finally we do have a lot of test for critical parts of the codebase which makes it easy for you to modify with confidence. I'm always available for questions or any sort of guidance so feel fee to reach out over twitter or discord.
+
+* [Getting Started](#getting-started)
+* [Setting Up the Development Environment](#setup-development-environment)
+   * [Prerequisites](#prerequisites)
+   * [Get the Super Graph source](#get-source-code)
+   * [Start the development envoirnment ](#start-the-development-envoirnment)
+   * [Testing](#testing-and-linting)
+* [Contributing](#contributing)
+   * [Guidelines](#guidelines)
+   * [Code style](#code-style)
+
+## Getting Started
+
+- Read the [Getting Started Guide](https://supergraph.dev/guide.html#get-started)
+
+## Setup Development Environment
+
+### Prerequisites
+
+- Install [Git](https://git-scm.com/) (may be already installed on your system, or available through your OS package manager)
+- Install [Go 1.13 or above](https://golang.org/doc/install)
+- Install [Docker](https://docs.docker.com/v17.09/engine/installation/)
+
+### Get source code
+
+The entire build flow uses `Makefile` there is a whole list of sub-commands you
+can use to build, test, install, lint, etc.
+
+```bash
+git clone https://github.com/dosco/super-graph 
+cd ./super-graph
+make help
+```
+
+### Start the development envoirnment
+
+The entire development flow is packaged into a `docker-compose` work flow. The below `up` command will launch A Postgres database, a example e-commerce app in Rails and Super Graph in development mode. The `db:seed` Rails task will insert sample data into Postgres.
+
+```bash
+docker-compose -f demo.yml run rails_app rake db:create db:migrate db:seed
+docker-compose up
+```
+
+### Learn how the code works
+
+[Super Graph codebase explained](https://supergraph.dev/internals.html)
+
+### Testing and Linting
+
+```
+make lint test
+```
+
+## Contributing
+
+### Guidelines
+
+- **Pull requests are welcome**, as long as you're willing to put in the effort to meet the guidelines.
+- Aim for clear, well written, maintainable code.
+- Simple and minimal approach to features, like Go.
+- Refactoring existing code now for better performance, better readability or better testability wins over adding a new feature.
+- Don't add a function to a module that you don't use right now, or doesn't clearly enable a planned functionality.
+- Don't ship a half done feature, which would require significant alterations to work fully.
+- Avoid [Technical debt](https://en.wikipedia.org/wiki/Technical_debt) like cancer.
+- Leave the code cleaner than when you began.
+
+### Code style
+
+- We're following [Go Code Review](https://github.com/golang/go/wiki/CodeReviewComments).
+- Use `go fmt` to format your code before committing.
+- If you see *any code* which clearly violates the style guide, please fix it and send a pull request. No need to ask for permission.
+- Avoid unnecessary vertical spaces. Use your judgment or follow the code review comments.
+- Wrap your code and comments to 100 characters, unless doing so makes the code less legible.

-Get an instant high performance GraphQL API for Postgres. No code needed. GraphQL is automatically transformed into efficient database queries.
+
+## What is Super Graph
+
+Is designed to 100x your developer productivity. Super Graph will instantly and without you writing code provide you a high performance and secure GraphQL API for Postgres DB. GraphQL queries are translated into a single fast SQL query. No more writing API code as you develop 
+your web frontend just make the query you need and Super Graph will do the rest.
+
+Super Graph has a rich feature set like integrating with your existing Ruby on Rails apps, joining your DB with data from remote APIs, role and attribute based access control, support for JWT tokens, built-in DB mutations and seeding, and a lot more.

 ## The story of Super Graph?
 
 After working on several products through my career I find that we spend way too much time on building API backends. Most APIs also require constant updating, this costs real time and money.

+## Why Super Graph
+
+Let's take a simple example say you want to fetch 5 products priced over 12 dollars along with the photos of the products and the users that owns them. Additionally also fetch the last 10 of your own purchases along with the name and ID of the product you purchased. This is a common type of query to render a view in say an ecommerce app. Lets be honest it's not very exciting write and maintain. Keep in mind the data needed will only continue to grow and change as your app evolves. Developers might find that most ORMs will not be able to do all of this in a single SQL query and will require n+1 queries to fetch all the data and assembly it into the right JSON response.
+
+What if I told you Super Graph will fetch all this data with a single SQL query and without you having to write a single line of code. Also as your app evolves feel free to evolve the query as you like. In our experience Super Graph saves us hundreds or thousands of man hours that we can put towards the more exciting parts of our app.

+If you want to import a lot of data using a CSV file is the best and fastest option. The `import_csv` command uses the `COPY FROM` Postgres method to load massive amounts of data into tables. The first line of the CSV file must be the header with column names.

+var post_count = import_csv("posts", "posts.csv")
+```

 You can generate the following fake data for your seeding purposes. Below is the list of fake data functions supported by the built-in fake data library. For example `fake.image_url()` will generate a fake image url or `fake.shuffle_strings(['hello', 'world', 'cool'])` will generate a randomly shuffled version of that array of strings or `fake.rand_string(['hello', 'world', 'cool'])` will return a random string from the array provided.

-### Advanced queries
+### Sorting
 
-Super Graph support complex queries where you can add filters, ordering,offsets and limits on the query.
+To sort or ordering results just use the `order_by` argument. This can be combined with `where`, `search`, etc to build complex queries to fit you needs.
+

+### Filtering
+
+Super Graph support complex queries where you can add filters, ordering,offsets and limits on the query. For example the below query will list all products where the price is greater than 10 and the id is not 5.
+
+```graphql
+query {

+Often you will need to create or update multiple related items at the same time. This can be done using nested mutations. For example you might need to create a product and assign it to a user, or create a user and his products at the same time. You just have to use simple json to define you mutation and Super Graph takes care of the rest.
 
-Variables (`$product_id`) and their values (`"product_id": 5`) can be passed along side the GraphQL query. Using variables makes for better client side code as well as improved server side SQL query caching. The build-in web-ui also supports setting variables. Not having to manipulate your GraphQL query string to insert values into it makes for cleaner

+
+### Pagination
+
+This is a must have feature of any API. When you want your users to go thought a list page by page or implement some fancy infinite scroll you're going to need pagination. There are two ways to paginate in Super Graph.
+
+ Limit-Offset
+This is simple enough but also inefficient when working with a large number of total items. Limit, limits the number of items fetched and offset is the point you want to fetch from. The below query will fetch 10 results at a time starting with the 100th item. You will have to keep updating offset (110, 120, 130, etc ) to walk thought the results so make offset a variable.
+
+```graphql
+query {
+  products(limit: 10, offset: 100) {
+    id
+    slug
+    name
+  }
+}
+```
+
+#### Cursor
+This is a powerful and highly efficient way to paginate though a large number of results. Infact it does not matter how many total results there are this will always be lighting fast. You can use a cursor to walk forward of backward though the results. If you plan to implement infinite scroll this is the option you should choose. 
+
+When going this route the results will contain a cursor value this is an encrypted string that you don't have to worry about just pass this back in to the next API call and you'll received the next set of results. The cursor value is encrypted since its contents should only matter to Super Graph and not the client. Also since the primary key is used for this feature it's possible you might not want to leak it's value to clients. 
+
+You will need to set this config value to ensure the encrypted cursor data is secure. If not set a random value is used which will change with each deployment breaking older cursor values that clients might be using so best to set it.
+
+```yaml
+# Secret key for general encryption operations like 
+# encrypting the cursor data
+secret_key: supercalifajalistics
+```
+
+Paginating forward through your results
+
+```json
+{
+  "variables": { 
+    "cursor": "MJoTLbQF4l0GuoDsYmCrpjPeaaIlNpfm4uFU4PQ="
+  }
+}
+```
+
+```graphql
+query {
+  products(first: 10, after: $cursor) {
+    slug
+    name
+  }
+}
+```
+
+Paginating backward through your results
+
+```graphql
+query {
+  products(last: 10, before: $cursor) {
+    slug
+    name
+  }
+}
+```
+
+```graphql
+"data": {
+   "products": [
+    {
+      "slug": "eius-nulla-et-8",
+      "name" "Pale Ale"
+    },
+    {
+      "slug": "sapiente-ut-alias-12",
+      "name" "Brown Ale"
+    }
+    ...
+  ],
+  "products_cursor": "dJwHassm5+d82rGydH2xQnwNxJ1dcj4/cxkh5Cer"
+}
+```
+
+Nested tables can also have cursors. Requesting multiple cursors are supported on a single request but when paginating using a cursor only one table is currently supported. To explain this better, you can only use a `before` or `after` argument with a cursor value to paginate a single table in a query.
+
+```graphql
+query {
+  products(last: 10) {
+    slug
+    name
+    customers(last: 5) {
+      email
+      full_name
+    }
+  }
+}
+```
+
+Multiple order-by arguments are supported. Super Graph is smart enough to allow cursor based pagination when you also need complex sort order like below.
+
+```graphql
+query {
+  products(
+    last: 10
+    before: $cursor
+    order_by: [ price: desc, total_customers: asc ]) {
+    slug
+    name
+  }
+}
+```
+
+
+## Using Variables
+
+Variables (`$product_id`) and their values (`"product_id": 5`) can be passed along side the GraphQL query. Using variables makes for better client side code as well as improved server side SQL query caching. The built-in web-ui also supports setting variables. Not having to manipulate your GraphQL query string to insert values into it makes for cleaner
 and better client side code.

+## GraphQL with React
+
+This is a quick simple example using `graphql.js` [https://github.com/f/graphql.js/](https://github.com/f/graphql.js/)
+
+```js
+import React, { useState, useEffect } from 'react'
+import graphql from 'graphql.js'
+
+// Create a GraphQL client pointing to Super Graph
+var graph = graphql("http://localhost:3000/api/v1/graphql", { asJSON: true })
+
+const App = () => {
+  const [user, setUser] = useState(null)
+  
+  useEffect(() => {
+    async function action() {
+      // Use the GraphQL client to execute a graphQL query
+      // The second argument to the client are the variables you need to pass
+      const result = await graph(`{ user { id first_name last_name picture_url } }`)()
+      setUser(result)
+    }
+    action()
+  }, []);
+
+  return (
+    <div className="App">
+      <h1>{ JSON.stringify(user) }</h1>
+    </div>
+  );
+}
+```
+
+export default App;
+
+## Advanced Columns
+
+The ablity to have `JSON/JSONB` and `Array` columns is often considered in the top most useful features of Postgres. There are many cases where using an array or a json column saves space and reduces complexity in your app. The only issue with these columns is the really that your SQL queries can get harder to write and maintain. 
+
+Super Graph steps in here to help you by supporting these columns right out of the box. It allows you to work with these columns just like you would with tables. Joining data against or modifying array columns using the `connect` or `disconnect` keywords in mutations is fully supported. Another very useful feature is the ability to treat `json` or `binary json (jsonb)` columns as seperate tables, even using them in nested queries joining against related tables. To replicate these features on your own will take a lot of complex SQL. Using Super Graph means you don't have to deal with any of this it just works.
+
+### Array Columns
+
+Configure a relationship between an array column `tag_ids` which contains integer id's for tags and the column `id` in the table `tags`.
+
+```yaml
+tables:
+  - name: posts
+    columns:
+      - name: tag_ids
+        related_to: tags.id
+
+```
+
+```graphql
+query {
+  posts {
+    title
+    tags {
+      name
+      image
+    }
+  }
+}
+```
+
+### JSON Column
+
+Configure a JSON column called `tag_count` in the table `products` into a seperate table. This JSON column contains a json array of objects each with a tag id and a count of the number of times the tag was used. As a seperate table you can nest it into your GraphQL query and treat it like table using any of the standard features like `order_by`, `limit`, `where clauses`, etc.
+
+The configuration below tells Super Graph to create a synthetic table called `tag_count` using the column `tag_count` from the `products` table. And that this new table has two columns `tag_id` and `count` of the listed types and with the defined relationships.
+
+```yaml
+tables:
+  - name: tag_count
+    table: products
+    columns:
+      - name: tag_id
+        type: bigint
+        related_to: tags.id
+      - name: count
+        type: int
+```
+
+```graphql
+query {
+  products {

+      count
+      tag {

+## API Security
+
+One of the the most common questions I get asked is what happens if a user out on the internet sends queries
+that we don't want run. For example how do we stop him from fetching all users or the emails of users. Our answer to this is that it is not an issue as this cannot happen, let me explain.
+
+Super Graph runs in one of two modes `development` or `production`, this is controlled via the config value `production: false` when it's false it's running in development mode and when true, production. In development mode all the **named** queries (including mutations) are saved to the allow list `./config/allow.list`. While in production mode when Super Graph starts only the queries from this allow list file are registered with the database as [prepared statements](https://stackoverflow.com/questions/8263371/how-can-prepared-statements-protect-from-sql-injection-attacks). 
+
+Prepared statements are designed by databases to be fast and secure. They protect against all kinds of sql injection attacks and since they are pre-processed and pre-planned they are much faster to run then raw sql queries. Also there's no GraphQL to SQL compiling happening in production mode which makes your queries lighting fast as they are directly sent to the database with almost no overhead.
+
+In short in production only queries listed in the allow list file `./config/allow.list` can be used, all other queries will be blocked. 
+
+::: tip How to think about the allow list?
+The allow list file is essentially a list of all your exposed API calls and the data that passes within them. It's very easy to build tooling to do things like parsing this file within your tests to ensure fields like `credit_card_no` are not accidently leaked. It's a great way to build compliance tooling and ensure your user data is always safe.
+:::
+
+This is an example of a named query, `getUserWithProducts` is the name you've given to this query it can be anything you like but should be unique across all you're queries. Only named queries are saved in the allow list in development mode.
+
+
+```graphql
+query getUserWithProducts {
+  users {
+    id
+    name
+    products {
+      id
+      name
+      price
+    }
+  }
+}
+```
+
+
+
+## Authentication
+
+You can only have one type of auth enabled either Rails or JWT. 
+
+### Ruby on Rails
+
+Almost all Rails apps use Devise or Warden for authentication. Once the user is
+authenticated a session is created with the users ID. The session can either be
+stored in the users browser as a cookie, memcache or redis. If memcache or redis is used then a cookie is set in the users browser with just the session id.
+
+Super Graph can handle all these variations including the old and new session formats. Just enable the right `auth` config based on how your rails app is configured.
+
+#### Cookie session store
+
+```yaml
+auth:
+  type: rails
+  cookie: _app_session
+
+  rails:
+    # Rails version this is used for reading the
+    # various cookies formats.
+    version: 5.2
+
+    # Found in 'Rails.application.config.secret_key_base'
+    secret_key_base: 0a248500a64c01184edb4d7ad3a805488f8097ac761b76aaa6c17c01dcb7af03a2f18ba61b2868134b9c7b79a122bc0dadff4367414a2d173297bfea92be5566
+
+```
+
+#### Memcache session store
+
+```yaml
+auth:
+  type: rails
+  cookie: _app_session
+
+  rails:
+    # Memcache remote cookie store.
+    url: memcache://127.0.0.1
+```
+
+#### Redis session store
+
+```yaml
+auth:
+  type: rails
+  cookie: _app_session
+
+  rails:
+    # Redis remote cookie store
+    url: redis://127.0.0.1:6379
+    password: ""
+    max_idle: 80
+    max_active: 12000
+```
+
+### JWT Tokens
+
+```yaml
+auth:
+  type: jwt
+
+  jwt:
+    # the two providers are 'auth0' and 'none'
+    provider: auth0 
+    secret: abc335bfcfdb04e50db5bb0a4d67ab9
+    public_key_file: /secrets/public_key.pem
+    public_key_type: ecdsa #rsa
+```
+
+For JWT tokens we currently support tokens from a provider like Auth0 or if you have a custom solution then we look for the `user_id` in the `subject` claim of of the `id token`. If you pick Auth0 then we derive two variables from the token `user_id` and `user_id_provider` for to use in your filters.
+
+We can get the JWT token either from the `authorization` header where we expect it to be a `bearer` token or if `cookie` is specified then we look there.
+
+For validation a `secret` or a public key (ecdsa or rsa) is required. When using public keys they have to be in a PEM format file.
+
+### HTTP Headers
+
+```yaml
+header:
+  name: X-AppEngine-QueueName
+  exists: true
+  #value: default
+```
+
+Header auth is usually the best option to authenticate requests to the action endpoints. For example you
+might want to use an action to refresh a materalized view every hour and only want a cron service like the Google AppEngine Cron service to make that request in this case a config similar to the one above will do. 
+
+The `exists: true` parameter ensures that only the existance of the header is checked not its value. The `value` parameter lets you confirm that the value matches the one assgined to the parameter. This helps in the case you are using a shared secret to protect the endpoint.
+
+### Named Auth
+
+```yaml
+# You can add additional named auths to use with actions
+# In this example actions using this auth can only be
+# called from the Google Appengine Cron service that
+# sets a special header to all it's requests
+auths:
+  - name: from_taskqueue
+    type: header
+    header:
+      name: X-Appengine-Cron
+      exists: true
+```
+
+In addition to the default auth configuration you can create additional named auth configurations to be used
+with features like `actions`. For example while your main GraphQL endpoint uses JWT for authentication you may want to use a header value to ensure your actions can only be called by clients having access to a shared secret
+or security header.
+
+## Actions
+
+Actions is a very useful feature that is currently work in progress. For now the best use case for actions is to
+refresh database tables like materialized views or call a database procedure to refresh a cache table, etc. An action creates an http endpoint that anyone can call to have the SQL query executed. The below example will create an endpoint `/api/v1/actions/refresh_leaderboard_users` any request send to that endpoint will cause the sql query to be executed. the `auth_name` points to a named auth that should be used to secure this endpoint. In future we have big plans to allow your own custom code to run using actions.
+
+```yaml
+actions:
+  - name: refresh_leaderboard_users
+    sql: REFRESH MATERIALIZED VIEW CONCURRENTLY "leaderboard_users"
+    auth_name: from_taskqueue
+```
+
+#### Using CURL to test a query
+
+```bash
+# fetch the response json directly from the endpoint using user id 5
+curl 'http://localhost:8080/api/v1/graphql' \
+  -H 'content-type: application/json' \
+  -H 'X-User-ID: 5' \
+  --data-binary '{"query":"{ products { name price users { email }}}"}'
+```
+
+## Access Control
+
+It's common for APIs to control what information they return or insert based on the role of the user. In Super Graph we have two primary roles `user` and `anon` the first for users where a `user_id` is available the latter for users where it's not.
+
+::: tip
+An authenticated request is one where Super Graph can extract an `user_id` based on the configured authentication method (jwt, rails cookies, etc).
+:::
+
+The `user` role can be divided up into further roles based on attributes in the database. For example when fetching a list of users, a normal user can only fetch his own entry while an admin can fetch all the users within a company and an admin user can fetch everyone. In some places this is called Attribute based access control. So in way we support both. Role based access control and Attribute based access control.
+
+Super Graph allows you to create roles dynamically using a `roles_query` and `  match` config values.
+
+### Configure RBAC
+
+```yaml
+roles_query: "SELECT * FROM users WHERE users.id = $user_id"
+
+roles:
+  - name: user
+    tables:
+      - name: users
+        query:
+          filters: ["{ id: { _eq: $user_id } }"]
+
+        insert:
+          filters: ["{ user_id: { eq: $user_id } }"]
+          columns: ["id", "name", "description" ]
+          presets:
+            - created_at: "now"
+            
+        update:
+          filters: ["{ user_id: { eq: $user_id } }"]
+          columns:
+            - id
+            - name
+          presets:
+            - updated_at: "now"
+
+        delete:
+          block: true
+
+  - name: admin
+    match: users.id = 1
+    tables:
+      - name: users
+        query:
+          filters: []
+```
+
+This configuration is relatively simple to follow the `roles_query` parameter is the query that must be run to help figure out a users role. This query can be as complex as you like and include joins with other tables. 
+
+The individual roles are defined under the `roles` parameter and this includes each table the role has a custom setting for. The role is dynamically matched using the `match` parameter for example in the above case `users.id = 1` means that when the `roles_query` is executed a user with the id `1` will be assigned the admin role and those that don't match get the `user` role if authenticated successfully or the `anon` role.
+
 ## Remote Joins
 
 It often happens that after fetching some data from the DB we need to call another API to fetch some more data and all this combined into a single JSON response. For example along with a list of users you need their last 5 payments from Stripe. This requires you to query your DB for the users and Stripe for the payments. Super Graph handles all this for you also only the fields you requested from the Stripe API are returned.

+## Database Relationships
 
-You can only have one type of auth enabled. You can either pick Rails or JWT.

 Configuration files can either be in YAML or JSON their names are derived from the `GO_ENV` variable, for example `GO_ENV=prod` will cause the `prod.yaml` config file to be used. or `GO_ENV=dev` will use the `dev.yaml`. A path to look for the config files in can be specified using the `-path <folder>` command line argument.

+## YugabyteDB
+
+Yugabyte is an open-source, geo-distrubuted cloud-native relational DB that scales horizontally. Super Graph works with Yugabyte right out of the box. If you think you're data needs will outgrow Postgres and you don't really want to deal with sharding then Yugabyte is the way to go. Just point Super Graph to your Yugabyte DB and everything will just work including running migrations, seeding, querying, mutations, etc.
+
+To use Yugabyte in your local development flow just uncomment the following lines in the `docker-compose.yml` file that is part of your Super Graph app. Also remember to comment out the originl postgres `db` config.
+
+```yaml

+# Super Graph Codebase Explained
+
+Super Graph code is made up of a number of packages. We have done our best to keep each package small and focused. Let us begin by looking at some of these packages.
+
+1. qcode - GraphQL lexer and parser.
+2. psql - SQL generator
+3. serv - HTTP Endpoint, Configs, CLI, etc
+4. rails - Rails cookie and session store decoders
+
+## QCODE
+
+This package contains the core of the GraphQL compiler it handling the lexing and parsing of the GraphQL query transforming it into an internal representation called
+`QCode`.
+
+This is the first step of the compiling process the `func NewCompiler(c Config)` function creates a new instance of this compiler which has it's own config. 
+
+Keep in mind QCode has no knowledge of the Database structure it is designed to be a fast GraphQL parser. Care is taken to keep memory allocations to a minimum.
+
+```go
+const (
+	opQuery
+	opMutate
+  ...
+)
+
+type QCode struct {
+	Type      QType
+  Selects   []Select
+  ...
+}
+
+type Select struct {
+	ID         int32
+	ParentID   int32
+	Args       map[string]*Node
+	Name       string
+	FieldName  string
+	Cols       []Column
+	Where      *Exp
+	OrderBy    []*OrderBy
+	DistinctOn []string
+	Paging     Paging
+	Children   []int32
+	Functions  bool
+	Allowed    map[string]struct{}
+	PresetMap  map[string]string
+	PresetList []string
+}
+```
+
+But before the incoming GraphQL query can be turned into QCode it must first be tokenzied by the lexer `lex.go`. As the tokenzier walks the bytes of the query it generates tokens `item` structs which are then consumed by the next step the parser `parse.go`.
+
+```go
+type item struct {
+	typ  itemType 
+	pos  Pos
+	end  Pos
+}
+```
+
+For exmple a simple query like `query getUser { user { id } }` will be converted into several tokens like below.
+
+```go
+item{itemQuery, 0, 4} // query
+item{itemName, 6, 12} // getUser
+item{itemObjOpen, 16, 20} // {
+...
+```
+
+These tokens are then fed into the parser `parse.go` the parser does the work of generating an abstract syntax tree (AST) from the tokens. This AST is an internal representation (data structure) and is not exposed outside the package. Since the AST is a tree a stack `stack.go` is used to walk the tree and generate the QCode AST. The QCode data structure is also a tree (represented as an array). This is then returned to the caller of the compile function.
+
+```go
+type Operation struct {
+	Type    parserType
+	Name    string
+	Args    []Arg
+	Fields  []Field
+}
+
+type Field struct {
+	ID        int32
+	ParentID  int32
+	Name      string
+	Alias     string
+	Args      []Arg
+	Children  []int32
+}
+```
+
+## PSQL
+
+This package is responsible for generating Postgres SQL from the QCode AST. There are various GraphQL query types (Query, Mutation, etc). And several more sub types like single root or multi-root queries, various types of mutations (insert, update delete, bulk insert, etc). This package is designed to be able to generate SQL for all of those types.
+
+In addition to QCode variable data is also passed to the compile function within this package. Variables are decoded to derive what is being inserted and what kind of insert is it single or bulk. This information is not available in the GraphQL query its passed in seperatly via variables. This package is able to put all this together and generate the right SQL code.
+
+The entry point of this package is in `query.go`. The database schema must be passed in the config object when creating a new compiler instance `NewCompiler`. The functions to extract this schema from the database are also part of this package `tables.go`. The `GetTables` functions fetches all the tables from the database and `GetColumns` fetches columns and relationship information.
+
+```go
+func NewCompiler(conf Config) *Compiler {
+	return &Compiler{conf.Schema, conf.Vars}
+}
+
+func (co *Compiler) Compile(qc *qcode.QCode, w io.Writer, vars Variables) (uint32, error) {
+	switch qc.Type {
+	case qcode.QTQuery:
+		return co.compileQuery(qc, w)
+	case qcode.QTInsert, qcode.QTUpdate, qcode.QTDelete, qcode.QTUpsert:
+		return co.compileMutation(qc, w, vars)
+	}
+
+	return 0, fmt.Errorf("Unknown operation type %d", qc.Type)
+}
+```
+
+GraphQL, input is first converted to QCode.
+
+```graphql
+query {
+  user {
+    id
+  }
+  posts {
+    title
+  }
+}
+```
+
+SQL, in reality the generated SQL is far more complex single it has to be very efficient, leverage the power of Postgres, support RBAC (Role based access control) and all of this must be done in a single SQL query.
+
+```sql
+SELECT users.id, posts.title FROM users, posts;
+```
+
+## SERV
+
+The `serv` package constains most of code that turns the above compiler into an HTTP service. It also includes authentication middleware, remote join resolvers, config parsering, database migrations and seeding commands.
+
+Another big feature that this package handles is the `allow.list` management code. In production mode parsing the allow list file and registering prepared statements to adding GraphQL queries to this file in development mode.
+
+Currently the following global variables are referrenced across the package. In future I'd prefer to move these into a context struct and pass that around instead.
+
+```go
+var (
+	logger   zerolog.Logger  // logger for everything but errors
+	errlog   zerolog.Logger  // logger for errors includes line numbers
+	conf     *config         // parsed config
+	confPath string          // path to the config file
+	db       *pgxpool.Pool   // database connection pool
+	schema   *psql.DBSchema  // database tables, columns and relationships
+	qcompile *qcode.Compiler // qcode compiler
+	pcompile *psql.Compiler  // postgres sql compiler
+)
+```
+
+## Testing
+
+There are several unit tests and benchmark tests `parse_test.go`) included. There are also scripts included for memory `pprof_cpu.sh` and cpu `pprof_cpu.sh` profiling. 
+
+```go
+// Test to ensure synthetic tables gnerate the correct SQL
+func syntheticTables(t *testing.T) {
+	gql := `query {
+		me {
+			email
+		}
+	}`
+
+	sql := `SELECT json_object_agg('me', json_0) FROM (SELECT row_to_json((SELECT "json_row_0" FROM (SELECT ) AS "json_row_0")) AS "json_0" FROM (SELECT "users"."email" FROM "users" WHERE ((("users"."id") = '{{user_id}}' :: bigint)) LIMIT ('1') :: integer) AS "users_0" LIMIT ('1') :: integer) AS "sel_0"`
+
+	resSQL, err := compileGQLToPSQL(gql, nil, "user")
+	if err != nil {
+		t.Fatal(err)
+	}
+
+	if string(resSQL) != sql {
+		t.Fatal(errNotExpected)
+	}
+}
+```
+
+You can run tests within each package or across the entire app. It is usually the fastest to first write a test and then build the feature to satisfy it.
+
+```
+go test -v ./...
+```
+
+Memory profiling can help find where allocations are happining within the package code.
