-## Remote Joins
+## GraphQL with React
 
-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. 
+This is a quick simple example using `graphql.js` [https://github.com/f/graphql.js/](https://github.com/f/graphql.js/)
 
-::: tip Is this fast?
-Super Graph is able fetch remote data and merge it with the DB response in an efficient manner. Several optimizations such as parallel HTTP requests and a zero-allocation JSON merge algorithm makes this very fast. All of this without you having to write a line of code.
-:::
+```js
+import React, { useState, useEffect } from 'react'
+import graphql from 'graphql.js'
 
-For example you need to list the last 3 payments made by a user. You will first need to look up the user in the database and then call the Stripe API to fetch his last 3 payments. For this to work your user table in the db has a `customer_id` column that contains his Stripe customer ID.
+// Create a GraphQL client pointing to Super Graph
+var graph = graphql("http://localhost:3000/api/v1/graphql", { asJSON: true })
 
-Similiarly you could also fetch the users last tweet, lead info from Salesforce or whatever else you need. It's fine to mix up several different `remote joins` into a single GraphQL query.
-
-### Stripe API example
-
-The configuration is self explanatory. A `payments` field has been added under the `customers` table. This field is added to the `remotes` subsection that defines fields associated with `customers` that are remote and not real database columns.
-
-The `id` parameter maps a column from the `customers` table to the `$id` variable. In this case it maps `$id` to the `customer_id` column.
-
-```yaml
-tables:
-  - name: customers
-    remotes:
-      - name: payments
-        id: stripe_id
-        url: http://rails_app:3000/stripe/$id
-        path: data
-        # debug: true
-        # pass_headers: 
-        #   - cookie
-        #   - host
-        set_headers:
-          - name: Authorization
-            value: Bearer <stripe_api_key>
-```
-
-#### How do I make use of this?
-
-Just include `payments` like you would any other GraphQL selector under the `customers` selector. Super Graph will call the configured API for you and stitch (merge) the JSON the API sends back with the JSON generated from the database query. GraphQL features like aliases and fields all work.
-
-```graphql
-query {
-  customers {
-    id
-    email
-    payments {
-      customer_id
-      amount
-      billing_details
+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>
+  );
 }
 ```
 
-And voila here is the result. You get all of this advanced and honestly complex querying capability without writing a single line of code.
-
-```json
-"data": {
-  "customers": [
-    {
-      "id": 1,
-      "email": "linseymertz@reilly.co",
-      "payments": [
-        {
-          "customer_id": "cus_YCj3ndB5Mz",
-          "amount": 100,
-            "billing_details": {
-            "address": "1 Infinity Drive",
-            "zipcode": "94024"
-          }
-        },
-      ...
-```
-
-Even tracing data is availble in the Super Graph web UI if tracing is enabled in the config. By default it is enabled in development. Additionally there you can set `debug: true` to enable http request / response dumping to help with debugging.

-## Easy to setup
+## Role based Access Control
+
+It's a common usecase for APIs to control what information they return or insert based on the role of the user. For example when fetching a list of users, a normal user can only fetch his own entry while a manager can fetch all the users within a company and an admin user can fetch everyone. Or when creating a new user an an admin user can set a users role while the user himself cannot set or change it. This is called role based access control or RBAC.
+
+Super Graph allows you to set access control rules based on dynamically defined roles. You can create as many roles as you wish. The only two default (built-in) roles are `user` for authenticated requests and `anon` for unauthenticated. An authenticated request is one where Super Graph can extract an `user_id` based on the configured authenication method (jwt, rails cookies, etc).
+
+### 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` willbe 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. 
+
+::: tip Is this fast?
+Super Graph is able fetch remote data and merge it with the DB response in an efficient manner. Several optimizations such as parallel HTTP requests and a zero-allocation JSON merge algorithm makes this very fast. All of this without you having to write a line of code.
+:::
+
+For example you need to list the last 3 payments made by a user. You will first need to look up the user in the database and then call the Stripe API to fetch his last 3 payments. For this to work your user table in the db has a `customer_id` column that contains his Stripe customer ID.
+
+Similiarly you could also fetch the users last tweet, lead info from Salesforce or whatever else you need. It's fine to mix up several different `remote joins` into a single GraphQL query.
+
+### Stripe API example
+
+The configuration is self explanatory. A `payments` field has been added under the `customers` table. This field is added to the `remotes` subsection that defines fields associated with `customers` that are remote and not real database columns.
+
+The `id` parameter maps a column from the `customers` table to the `$id` variable. In this case it maps `$id` to the `customer_id` column.
+
+```yaml
+tables:
+  - name: customers
+    remotes:
+      - name: payments
+        id: stripe_id
+        url: http://rails_app:3000/stripe/$id
+        path: data
+        # debug: true
+        # pass_headers: 
+        #   - cookie
+        #   - host
+        set_headers:
+          - name: Authorization
+            value: Bearer <stripe_api_key>
+```
+
+#### How do I make use of this?
+
+Just include `payments` like you would any other GraphQL selector under the `customers` selector. Super Graph will call the configured API for you and stitch (merge) the JSON the API sends back with the JSON generated from the database query. GraphQL features like aliases and fields all work.
+
+```graphql
+query {
+  customers {
+    id
+    email
+    payments {
+      customer_id
+      amount
+      billing_details
+    }
+  }
+}
+```
+
+And voila here is the result. You get all of this advanced and honestly complex querying capability without writing a single line of code.
+
+```json
+"data": {
+  "customers": [
+    {
+      "id": 1,
+      "email": "linseymertz@reilly.co",
+      "payments": [
+        {
+          "customer_id": "cus_YCj3ndB5Mz",
+          "amount": 100,
+            "billing_details": {
+            "address": "1 Infinity Drive",
+            "zipcode": "94024"
+          }
+        },
+      ...
+```
+
+Even tracing data is availble in the Super Graph web UI if tracing is enabled in the config. By default it is enabled in development. Additionally there you can set `debug: true` to enable http request / response dumping to help with debugging.

+
+## Configuration files
 
 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.
 
 We're tried to ensure that the config file is self documenting and easy to work with.

 If deploying into environments like Kubernetes it's useful to be able to configure things like secrets and hosts though environment variables therfore we expose the below environment variables. This is escpecially useful for secrets since they are usually injected in via a secrets management framework ie. Kubernetes Secrets
