## What it is
A sample repository from Microsoft demonstrating how to use Babel CLI to transpile TypeScript to JavaScript while using the TypeScript compiler for type-checking. It includes step-by-step setup instructions and examples for integrating JSX/React, Webpack, and Rollup.

## Use cases
- set up a TypeScript project that builds with Babel
- use Babel for transpilation and tsc only for type-checking
- configure a TypeScript React project with Babel and Webpack
- bundle a TypeScript library with Rollup and Babel
- learn how Babel and TypeScript fit together in a build pipeline

## When to choose
- you want fast TypeScript transpilation via Babel with separate type-checking
- you need a reference setup for TypeScript with JSX/React and bundlers
- you are learning how to wire Babel and TypeScript together manually

## When to avoid
- you want a full-featured production build system with batteries included
- you prefer an all-in-one toolchain like ts-node, esbuild, or Vite
- you need an actively maintained template with recent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: build-tool, developer-tools
- domain: developer-tools, web-development, tutorials
- platform: cross-platform
- tags: babel, typescript, starter-template, boilerplate, type-checking, webpack, rollup, nodejs
