TypeScript and Chill

Overview

TypeScript and Chill is an NPM package that automates the process of setting up a modern TypeScript development environment. Designed for developers working with AWS CDK, serverless applications, and microservices, this CLI tool ensures that every new project starts with a standardized and optimized development environment.

This tool eliminates the need for manually setting up ESLint, Prettier, Jest, AWS CDK, and CI/CD pipelines, saving time and reducing setup inconsistencies across projects.

Features

✅ Interactive CLI Setup - Choose what to install based on project needs, or use the -y flag for automatic setup
✅ Project Structure Creation - Automatically sets up directories for CDK and source code
✅ AWS CDK Initialization - Ensures an up-to-date cdk.json configuration with the correct bin reference
✅ Linting & Formatting - Installs and configures Biome ✅ Testing - Configures Vitest for unit testing
✅ CI/CD Integration - Automatically sets up GitHub Actions for deployment
✅ Automatic TypeScript Compilation - Installs and configures esbuild
✅ Deployment Ready - Ensures TypeScript projects are ready for AWS deployments

Installation

To install and use this package in a new project:

npx typescript-and-chill

To automatically accept all default options and install everything:

npx typescript-and-chill -y

This will run the interactive CLI (or default to "yes" for all options if -y is used), guiding you through the setup process.

How It Works

When you run npx typescript-and-chill, the CLI:

1. Prompts for setup options (CDK, Jest, ESLint, etc.), unless -y is specified.
2. Installs dependencies (aws-cdk, biome, vitest, typescript, esbuild).
3. Creates project directories (cdk/, cdk/stacks/, src/).
4. Generates configuration files (.biome.json, cdk.json).
5. Ensures cdk.json is updated - The correct bin file reference is automatically set.
6. Sets up CI/CD - Adds a GitHub Actions workflow for automated deployments.
7. Ensures TypeScript Compilation - Installs esbuild for efficient TS-to-JS compilation.

Directory Structure

After running the CLI, your project will have the following structure:

my-new-project/
├── bin/
│   ├── app.ts       # CDK application entry file
├── cdk/
│   ├── stacks/      # CDK stacks directory
├── src/             # Application source code (Lambda functions, etc.)
├── .github/workflows/
│   ├── deploy.yml   # CI/CD GitHub Actions workflow
├── package.json     # Project dependencies and scripts
├── README.md        # Documentation
├── tsconfig.json    # TypeScript configuration
├── .biome.json      # Biome configuration
├── cdk.json         # AWS CDK configuration (correctly references bin/app.js)
└── .gitignore       # Git ignore rules

Customization

You can choose which features to enable during setup:

• Install AWS CDK (cdk init is automatically run for accuracy).
• Enable Biome for testing.
• Add CI/CD GitHub Actions workflow.
• Install TypeScript and esbuild for deployments.
• Use -y to skip prompts and install everything automatically.

Running Tests

Unit tests ensure that all setup scripts function correctly:

npm test

This will run Vitest tests that validate the correct setup of Biome, Vitest, AWS CDK, CI/CD workflows, and TypeScript compilation.
