Install with npm

You can also install the CLI globally

npm i -g matron
matron --help

Quick start

The minimal setup required to use matron and scaffold a new project is a matron.yml file.

Let's start with the example below:

📄 matron.yml

jobs:
  create-folder:
    name: Create project folder
    steps:
      - RUN: npx mkdirp ${PROJECT_PATH}
  init-project:
    name: Initialize package.json
    steps:
      - WORKDIR: ${PROJECT_PATH}
      - RUN: npm init -y
  add-typescript:
    name: Add TypeScript
    steps:
      - RUN: yarn add -D typescript

▶️ matron command

matron create --matron-file=./matron.yml --project my-project

Let's break down each steps:

1. Create project folder

   1. RUN: npx mkdirp ${PROJECT_PATH}: With the RUN command you can execute any command that is possible to execute on your shell.
   2. Here we are using mkdirp to create a folder at the path my-project.
   3. ${PROJECT_PATH} is a default environment variable provided when you specify the option --project.

2. Initialize package.json

   1. WORKDIR: ${PROJECT_PATH}: With the WORKDIR command, all the subsequent RUN commands will be executed in the specified path, in this case ${PROJECT_PATH} equals my-project.
   2. RUN: npm init -y: This will create a minimal package.json file.
3. Add TypeScript
   1. RUN: yarn add -D typescript: Add TypeScript as dev dependencies.

When executed, this will result in the following file tree:

my-project
├── node_modules
├── package.json
└── yarn.lock
