Advanced tools
Package description
The babel-core package is a part of Babel, a JavaScript compiler that allows developers to use next-generation JavaScript, today. It transforms ES6, ES7, and beyond into backwards compatible versions of JavaScript that can be run on older browsers and environments. It also allows for the use of JSX, Flow, TypeScript, and other features not natively supported in all environments.
Code Transformation
Transforms ES6/ES7 code to ES5. This is useful for compatibility with older browsers and environments.
babel.transform('code();', options);File Transformation
Synchronously transforms the entire contents of a file. Useful for build processes.
babel.transformFileSync('filename.js', options);AST Generation
Parses code to its Abstract Syntax Tree (AST) representation, which can be used for analysis or modification of the code.
babel.parse('code();', options);Plugin/Preset Application
Applies Babel plugins and presets to the code, allowing for custom transformations and feature sets.
babel.transform('code();', { plugins: ['plugin-name'], presets: ['preset-name'] });TypeScript is a superset of JavaScript that compiles to plain JavaScript. It offers type checking and is aimed at the development of large applications. It is similar to Babel in that it processes modern JavaScript features, but it also introduces its own syntax and type system.
Esbuild is an extremely fast JavaScript bundler and minifier. It also transpiles code, similar to Babel, but it focuses on build performance and speed, often outperforming Babel in these aspects.
SWC is a super-fast compiler written in Rust that functions similarly to Babel. It focuses on speed and also offers minification. SWC can be a drop-in replacement for Babel in many cases, offering faster build times.
Readme
Babel compiler core.
$ npm install babel-core
import * as babel from 'babel-core';
const code = `class Example {}`;
const result = babel.transform(code, { /* options */ });
result.code; // Generated code
result.map; // Sourcemap
result.ast; // AST
