rocket-diesel-rest-api-example's Introduction

Rocket, Diesel, MySQL, Rest API Tutorial

Build Restful CRUD API for a managing heroes within our Database using Rocket and Diesel.

Requirements

Rust and Cargo - 1.26.0 (nightly)
Diesel CLI - 1.1.0
Mysql - 5.x.x

Steps to Setup

1. Clone the application

git clone https://github.com/sean3z/rocket-diesel-rest-api-example.git

2. Create DATABASE_URL environment variable

export DATABASE_URL=mysql://user:pass@localhost/heroes

3. Run Database migration

diesel migration run

4. Build and run the app using cargo

cargo build --release && cd target/release/
sudo ROCKET_ENV=prod ./hero-api

The app will start running at http://localhost:80.

Alternatively, you can run the app in development mode -

cargo run

Explore Rest APIs

The app defines following CRUD APIs.

GET /heroes

POST /hero

PUT /hero/{heroId}

DELETE /hero/{heroId}

You can test them using postman or any other rest client.
