---

Prerequisites

• Node.js - 6.9.0 or above
• Yarn - 1.0.0 or above
• NPM - 3.10.8 or above

Setup

Clone the repository, install the dependencies and get started right away.

$ git clone [email protected]:mesaugat/express-api-es6-starter.git <application-name>
$ cd <application-name>
$ rm -rf .git
$ yarn   # or npm install

Make a copy of .env.example as .env and update your application details and database credentials. Now, run the migrations and seed the database.

$ yarn migrate
$ yarn seed

Finally, start the application.

$ yarn start:dev (For development)
$ yarn start (For production)

Navigate to http://localhost:8848/api-docs/ to verify installation.

Creating new Migrations and Seeds

These are the commands to create a new migration and corresponding seed file.

$ yarn make:migration <name>
$ yarn make:seeder <name>

Example,

$ yarn make:migration create_tags_table
$ yarn make:seeder 02_insert_tags

Setup Using Docker

Use docker-compose to quickly bring up a stack with pre-configured Postgres database container. Data is ephemeral and containers will disappear when stack is removed.

Specific configuration for Docker is in .env.docker

• 0.0.0.0 as $APP_HOST to expose app on Docker network interface
• Pre-configured Postgres settings - can be updated to point to another Postgres host

Bring up stack,

$ docker-compose up

Navigate to http://localhost:8848/api-docs/ to verify application is running from docker.

Bring down stack,

$ docker-compose down

Using MySQL instead of PostgreSQL

Install the mysql driver first. Update these lines DB_CLIENT='pg' and DB_PORT='5432' in your .env file to DB_CLIENT='mysql' and DB_PORT='3306' respectively.

You can remove the pg driver if you like to.

$ yarn add mysql
$ yarn remove pg

That's it, you are ready to roll.

Tests

To run the tests you need to create a separate test database. Don't forget to update your .env file to include the name of the test database and run the migrations.

$ NODE_ENV=test yarn migrate
$ yarn test

Run tests with coverage.

$ yarn test:coverage
