What is @swc/core-darwin-x64?

@swc/core-darwin-x64 is a precompiled binary of the SWC (Speedy Web Compiler) core for macOS on x64 architectures. SWC is a super-fast compiler written in Rust that can be used to transpile JavaScript and TypeScript code to a lower version of JavaScript, enabling compatibility with older browsers or environments. It can also minify code and handle JSX for React applications.

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

JavaScript/TypeScript Transpilation

This feature allows you to transpile TypeScript or modern JavaScript to a compatible version for older browsers or environments. The code sample demonstrates how to transpile TypeScript code to ES5.

const swc = require('@swc/core-darwin-x64');

swc.transformSync('const x: number = 123;', {
  filename: 'input.ts',
  jsc: {
    parser: {
      syntax: 'typescript',
    },
    target: 'es5',
  }
});

Code Minification

This feature enables the minification of JavaScript code to reduce file size, which is beneficial for production environments. The code sample shows how to minify a simple JavaScript expression.

const swc = require('@swc/core-darwin-x64');

swc.transformSync('const x = 1 + 2;', {
  minify: true
});

JSX Handling

This feature is used to transform JSX syntax into JavaScript code that can be understood by browsers or other environments. The code sample demonstrates how to handle JSX for a React application.

const swc = require('@swc/core-darwin-x64');

swc.transformSync('<div>Hello, SWC!</div>', {
  jsc: {
    parser: {
      syntax: 'ecmascript',
      jsx: true
    },
    transform: {
      react: {
        pragma: 'React.createElement',
        pragmaFrag: 'React.Fragment',
        throwIfNamespace: true,
        development: false,
        useBuiltins: false
      }
    }
  }
});
