* Trends, Why APIs are Important
|
|
|
|
|
|
|
|
|
|
- An API first world
|
|
|
|
|
- Rise of API only startups
|
|
|
|
|
- Rise of integrations
|
|
|
|
|
- Rise of fullstack developers
|
|
|
|
|
- Rise of Single-Page-Apps
|

|
* Web Development Today
|
|
|
|
|
|
|
|
|
|
A big part of web development is building CRUD APIs to read
|
|
|
|
|
update and delete things from a database.
|
|
|
|
|
|
|
|
|
|
Get all products that belong to user 5
|
|
|
|
|
.link http://your-startup.com/apis/v1/users/5/products
|
|
|
|
|
|
|
|
|
|
Another way to do this
|
|
|
|
|
.link http://your-startup.com/apis/v1/products?user_id=5
|
|
|
|
|
|
|
|
|
|
Maybe you just need only cheaper products
|
|
|
|
|
.link http://your-startup.com/apis/v1/products?user_id=5&price_under=12
|
|
|
|
|
|
|
|
|
|
* So what's the problem here?
|
|
|
|
|
|
|
|
|
|
- Too many decisions no real standards
|
|
|
|
|
- Harder to be consistant
|
|
|
|
|
- Rinse and repeat for every new API
|
|
|
|
|
- Too much data over the wire
|
|
|
|
|
- Boring, we rather work on more interesting things
|
|
|
|
|
- Slows down dev. cycles
|
|
|
|
|
|
|
|
|
|
* GraphQL
|
|
|
|
|
|
|
|
|
|
query {
|
|
|
|
|
user(id: 5) {
|
|
|
|
|
|
|
|
|
|
products {
|
|
|
|
|
id
|
|
|
|
|
name
|
|
|
|
|
photo : image
|
|
|
|
|
|
|
|
|
|
customers {
|
|
|
|
|
name
|
|
|
|
|
email
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
* Perceived bad parts of GraphQL
|
|
|
|
|
|
|
|
|
|
- Perceived as new and shiny
|
|
|
|
|
- Not cache friendly (Not true)
|
|
|
|
|
- Only best data fetching
|
|
|
|
|
- New frameworks to learn
|
|
|
|
|
- Is it just an API gateway?
|
|
|
|
|
- Write more code
|
|
|
|
|
|
|
|
|
|
* Super Graph - An instant GraphQL API for Postgres
|
|
|
|
|
|
|
|
|
|
- GraphQL without writing any code
|
|
|
|
|
- Automatically learns your database
|
|
|
|
|
- Full text search, Aggregations, etc
|
|
|
|
|
- Supports Rails cookies and JWT tokens
|
|
|
|
|
- Join with remote REST APIs
|
|
|
|
|
- Highly optimized and fast Postgres SQL queries
|
|
|
|
|
- High performance GO codebase
|
|
|
|
|
- Tiny docker image and low memory requirements
|
|
|
|
|
|
|
|
|
|
* Let's talk about Postgres DB
|
|
|
|
|
|
|
|
|
|
- Atomicity, Consistency, Isolation, and Durability
|
|
|
|
|

|
|
|
|
|
- Full-text search

|
|
|
|
|
- Custom Columns (Bloomfilter, etc)
|
|
|
|
|
- Nearest Neighbour Searches (GIST Index)
|
|
|
|
|
- Row level security
|
|
|
|
|
