* 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 support for JSON
- Full-text search
- Graph DB (WITH RESURSIVE clause)
- Timeseries DB (WINDOW functions)
- GIS Location DB (PostGIS)
- Custom Columns (Bloomfilter, etc)
- Nearest Neighbour Searches (GIST Index)
- Row level security
- Versioning support
All your micro-services in one
* Super Graph gives Fullstack Devs superpowers
