Implementing API Endpoints and Serialization
Build API endpoints, handle request and response bodies, and serialize data efficiently for client consumption.
API Endpoints: The Basics
Welcome! In this lesson, we'll build API endpoints in Phoenix. An API endpoint is a specific URL that an API client can access to perform an action or retrieve data.
Think of it as a digital address for a specific resource, like /api/products or /api/users/123. Each endpoint usually corresponds to an action (e.g., get all products, create a new user).
Scaffolding an API Resource
Phoenix provides a handy generator to quickly set up a RESTful API resource. We'll use mix phx.gen.json to create a Product resource.
This command generates:
- A router entry
- A controller (e.g.,
ProductController) - An Ecto schema (e.g.,
Product) - A view (e.g.,
ProductView) for JSON serialization
