@next/swc-win32-x64-msvc

What is @next/swc-win32-x64-msvc?

The @next/swc-win32-x64-msvc package is a precompiled binary of SWC (Speedy Web Compiler) specifically for Windows (win32) with x64 architecture using the MSVC (Microsoft Visual C++) compiler. SWC is a super-fast compiler written in Rust that allows for transforming ECMAScript 2015+ code into a backward-compatible version of JavaScript that can be run in older browsers. It's designed to be highly performant and is often used as a faster alternative to Babel.

What are @next/swc-win32-x64-msvc's main functionalities?

JavaScript/TypeScript Compilation

This feature allows for the compilation of JavaScript or TypeScript code into a version of JavaScript that is compatible with older browsers or environments. The code sample demonstrates how to use the package to compile TypeScript code into ES2015 JavaScript.

"use strict";
const swc = require('@next/swc-win32-x64-msvc');

async function compile(jsCode) {
  const result = await swc.transform(jsCode, {
    jsc: {
      parser: {
        syntax: 'typescript',
        tsx: false,
        decorators: false,
        dynamicImport: false
      },
      target: 'es2015'
    }
  });
  return result.code;
}

compile('let x: number = 123;').then(console.log);

Minification

This feature enables the minification of JavaScript code to reduce its size, making it more efficient to download and execute. The code sample shows how to minify a simple piece of JavaScript code.

"use strict";
const swc = require('@next/swc-win32-x64-msvc');

async function minify(jsCode) {
  const result = await swc.transform(jsCode, {
    minify: true
  });
  return result.code;
}

minify('const x = 1 + 2;').then(console.log);

Other packages similar to @next/swc-win32-x64-msvc

@babel/core

Babel is a widely used JavaScript compiler that allows developers to transform modern JavaScript into backward-compatible versions. Compared to @next/swc-win32-x64-msvc, Babel is more established with a larger ecosystem of plugins, but SWC offers significantly faster compilation times due to its Rust-based implementation.

typescript

The TypeScript compiler is another alternative that offers compilation of TypeScript code into JavaScript. While it provides strong type checking and is designed specifically for TypeScript, SWC supports both JavaScript and TypeScript and focuses on speed and efficiency.

uglify-js

UglifyJS is a JavaScript minifier that can parse, minify, and compress JavaScript files. While it's focused solely on minification, unlike @next/swc-win32-x64-msvc which offers both compilation and minification, UglifyJS is a popular choice for projects that only need to reduce the size of their JavaScript code.
