@swc/core-darwin-x64
Advanced tools
@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.
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
}
}
}
});Babel is a widely-used JavaScript compiler that allows you to use next-generation JavaScript, today. It can transpile ES6 and beyond into backwards compatible JavaScript and handle JSX for React applications. Babel is plugin-based and has a larger ecosystem, but it is generally slower than SWC.
The TypeScript compiler is used to transpile TypeScript code to JavaScript. It provides type checking and the latest ECMAScript features. While TypeScript is powerful for type checking, it is not as fast as SWC for transpilation and does not include minification.
UglifyJS is a JavaScript minifier that can parse, minify, and compress JavaScript files. It is focused on minification and does not handle transpilation or JSX transformation, making it less versatile than SWC but still useful for reducing the size of JavaScript files.
Esbuild is an extremely fast JavaScript bundler and minifier. It can also transpile JavaScript and TypeScript code. Esbuild is known for its speed, which rivals that of SWC, and it has a simple API. However, it does not have as extensive a plugin ecosystem as Babel.
