JavaScript/TypeScript Compilation

This feature allows you to compile JavaScript or TypeScript code to a specified ECMAScript version. The example demonstrates transforming modern JavaScript code to ES5.

const swc = require('@swc/core');

const inputCode = `const greet = (name) => { return `Hello, ${name}!`; };`;

swc.transform(inputCode, { jsc: { target: 'es5' } }).then(output => {
  console.log(output.code);
});

Minification

This feature enables code minification, reducing the size of the output JavaScript file. The example shows how to minify a simple addition function.

const swc = require('@swc/core');

const inputCode = `function add(a, b) { return a + b; }`;

swc.transform(inputCode, { minify: true }).then(output => {
  console.log(output.code);
});

Source Maps

This feature generates source maps, which are useful for debugging by mapping the transformed code back to the original source. The example demonstrates generating a source map for a simple function.

const swc = require('@swc/core');

const inputCode = `const greet = (name) => { return `Hello, ${name}!`; };`;

swc.transform(inputCode, { sourceMaps: true }).then(output => {
  console.log(output.map);
});
