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

The @swc/core-win32-x64-msvc package is a precompiled binary of the SWC (Speedy Web Compiler) core specifically for Windows 64-bit systems using the MSVC compiler. SWC is a super-fast compiler written in Rust that compiles JavaScript/TypeScript down to efficient, optimized JavaScript code. It is designed to be a faster alternative to Babel with support for modern JavaScript features and TypeScript.

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

JavaScript/TypeScript Compilation

This feature allows the compilation of modern JavaScript or TypeScript code into a version compatible with older environments. The code sample demonstrates how to transform a simple piece of JavaScript code to be compatible with ES5 standards.

import { transformSync } from '@swc/core';

const sourceCode = `const x = 1 + 2;`;
const output = transformSync(sourceCode, {
  jsc: {
    target: 'es5'
  }
});
console.log(output.code);

Minification

This feature enables the minification of JavaScript code to reduce its size and improve load times on web pages. The code sample shows how to minify a simple function.

import { transformSync } from '@swc/core';

const sourceCode = `function add(a, b) { return a + b; }`;
const output = transformSync(sourceCode, {
  minify: true
});
console.log(output.code);

Source Maps

This feature provides support for source maps, which help in debugging by mapping the transformed code back to the original source code. The code sample demonstrates generating a source map for a simple expression.

import { transformSync } from '@swc/core';

const sourceCode = `const x = 1 + 2;`;
const output = transformSync(sourceCode, {
  sourceMaps: true
});
console.log(output.map);
