projen

What is projen?

Projen is a tool that helps you manage and maintain project configuration files. It automates the creation and maintenance of project files like package.json, tsconfig.json, and more, ensuring consistency and reducing manual effort.

What are projen's main functionalities?

Project Initialization

This feature allows you to initialize a new Node.js project with predefined settings. The code sample demonstrates how to create a new Node.js project with Projen, specifying the project name, default release branch, and dependencies.

const { NodeProject } = require('projen');
const project = new NodeProject({
  name: 'my-node-project',
  defaultReleaseBranch: 'main',
  deps: ['express'],
});
project.synth();

Automated Dependency Management

Projen can automatically manage your project's dependencies. The code sample shows how to set up a project with both runtime and development dependencies, which Projen will manage for you.

const { NodeProject } = require('projen');
const project = new NodeProject({
  name: 'my-node-project',
  deps: ['express'],
  devDeps: ['jest'],
});
project.synth();

Customizable Project Configuration

Projen allows you to customize various aspects of your project configuration. The code sample demonstrates how to add custom scripts and Jest configuration to a Node.js project.

const { NodeProject } = require('projen');
const project = new NodeProject({
  name: 'my-node-project',
  scripts: {
    start: 'node index.js',
  },
  jestOptions: {
    jestConfig: {
      testEnvironment: 'node',
    },
  },
});
project.synth();

Other packages similar to projen

yeoman-generator

Yeoman Generator is a scaffolding tool that helps you kickstart new projects by providing a generator ecosystem. Unlike Projen, which focuses on maintaining and managing project configurations, Yeoman is more about generating project structures and boilerplate code.

create-react-app

Create React App is a tool to set up a new React project with a single command. While it simplifies the initial setup of a React project, it doesn't offer the same level of ongoing project configuration management that Projen provides.

nx

Nx is a set of extensible dev tools for monorepos, which helps you manage multiple projects within a single repository. While it offers some overlapping features with Projen, such as dependency management, Nx is more focused on monorepo management and optimization.
