@swc/core-win32-arm64-msvc

What is @swc/core-win32-arm64-msvc?

@swc/core-win32-arm64-msvc is a high-performance JavaScript/TypeScript compiler written in Rust. It is designed to be a drop-in replacement for Babel, offering faster compilation times and lower memory usage. This specific package is tailored for Windows on ARM64 architecture with the MSVC toolchain.

What are @swc/core-win32-arm64-msvc's main functionalities?

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);
});

Other packages similar to @swc/core-win32-arm64-msvc

babel

Babel is a widely-used JavaScript compiler that allows you to use next-generation JavaScript, today. It has a rich plugin ecosystem and is highly configurable. Compared to @swc/core-win32-arm64-msvc, Babel is more mature and has broader community support, but it is generally slower in terms of compilation speed.

esbuild

esbuild is an extremely fast JavaScript bundler and minifier. It is written in Go and offers blazing fast performance. While esbuild is faster than @swc/core-win32-arm64-msvc in many cases, it is less configurable and has fewer features related to code transformation.

terser

Terser is a JavaScript parser, mangler, and compressor toolkit for ES6+. It is primarily used for minification. Compared to @swc/core-win32-arm64-msvc, Terser focuses solely on minification and does not offer the same breadth of features for code transformation.
