Getting started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

What things you need to install the software and how to install them :

• Git
• Node.js
• Docker

Installation

1. Clone the git repository

   git clone https://github.com/smarlhens/nest-boilerplate.git

2. Go into the project directory

   cd nest-boilerplate/

3. Checkout working branch

   git checkout <branch>

4. Install NPM dependencies

   npm i

5. Copy .env.dist to .env

   cp .env.dist .env

6. Replace the values of the variables with your own

7. Create Docker images and launch them

   docker-compose up -d --build

What’s in the box ?

CircleCI

CircleCI automates your software builds, tests, and deployments.

CircleCI pipeline file: .circleci/config.yml.

For more configuration options and details, see the configuration docs.

Commitizen

Configuration file: .commitlintrc.json.

In general the pattern mostly looks like this:

type(scope?): subject  #scope is optional

Are you a good commitizen ?

Docker Compose

Containers :

• PostgreSQL 14
• pgAdmin 6

Compose file uses .env.

ESLint

ESLint is a fully pluggable tool for identifying and reporting on patterns in JavaScript.

Configuration file: .eslintrc.js.

For more configuration options and details, see the configuration docs.

GitHub Actions

GitHub Actions makes it easy to automate all your software workflows, now with world-class CI/CD. Build, test, and deploy your code right from GitHub. Make code reviews, branch management, and issue triaging work the way you want.

CI workflow file: .github/workflows/ci.yml.

Husky

Husky is a package that helps you create Git hooks easily.

Configuration folder: .husky.

Lint-staged

Lint-staged is a Node.js script that allows you to run arbitrary scripts against currently staged files.
