What is @babel/cli?

The @babel/cli package is a command-line interface for Babel, a widely used JavaScript compiler. It allows developers to compile their JavaScript files using Babel directly from the command line. This package is particularly useful for compiling modern JavaScript down to a version that is compatible with older browsers or environments. It supports various functionalities such as file transformation, watching files for changes, and outputting the compiled code.

What are @babel/cli's main functionalities?

File Transformation

This feature allows you to transform a single JavaScript file. The command takes an input file (src/index.js) and compiles it into an output file (compiled.js).

babel src/index.js --out-file compiled.js

Directory Transformation

Transforms all JavaScript files in a directory. This command compiles all files in the 'src' directory and outputs the compiled files into the 'lib' directory.

babel src --out-dir lib

Watch Mode

Automatically recompiles files when they change. This command watches all files in the 'src' directory for changes and recompiles them to the 'lib' directory whenever any file is modified.

babel src --watch --out-dir lib
