@babel/standalone
Advanced tools
Package description
@babel/standalone is a standalone build of Babel for use in browsers and other non-Node.js environments. It allows you to transpile ES6+ code to ES5 directly in the browser or other environments without needing a build step.
Transpile ES6+ to ES5
This feature allows you to transpile modern JavaScript (ES6+) to older versions (ES5) directly in the browser. The code sample demonstrates how to transform an ES6 arrow function to ES5 using the 'env' preset.
const inputCode = 'const arrowFunction = () => {};';
const outputCode = Babel.transform(inputCode, { presets: ['env'] }).code;
console.log(outputCode);
Use Babel plugins
You can use Babel plugins to transform specific JavaScript features. The code sample shows how to transform ES6 classes to ES5 using the 'transform-es2015-classes' plugin.
const inputCode = 'class Example {}';
const outputCode = Babel.transform(inputCode, { plugins: ['transform-es2015-classes'] }).code;
console.log(outputCode);
Custom Babel configurations
You can customize Babel configurations to target specific environments. The code sample demonstrates how to use the 'env' preset with custom browser targets.
const inputCode = 'const x = 1;';
const outputCode = Babel.transform(inputCode, { presets: [['env', { targets: { browsers: ['last 2 versions'] } }]] }).code;
console.log(outputCode);
TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It offers type-checking and transpilation from TypeScript to JavaScript. Unlike @babel/standalone, TypeScript focuses on adding static types to JavaScript.
Traceur is a JavaScript.next-to-JavaScript-of-today compiler. It allows you to use features from the latest JavaScript standard (ES6 and beyond) and compiles them to ES5. Traceur is similar to @babel/standalone but is less flexible in terms of plugins and presets.
esbuild is an extremely fast JavaScript bundler and minifier. It supports modern JavaScript and TypeScript syntax and can transpile to older versions of JavaScript. Unlike @babel/standalone, esbuild is designed for speed and efficiency in build processes.
