@esbuild/darwin-x64

What is @esbuild/darwin-x64?

The @esbuild/darwin-x64 npm package is a binary package for the esbuild bundler optimized for macOS on x64 architectures. Esbuild is a fast JavaScript bundler and minifier. It compiles TypeScript and JavaScript into efficient code that can be executed in the browser or on Node.js. This package specifically contains the esbuild binary for macOS (Darwin) systems with x64 architecture, facilitating web development tasks such as bundling, minification, and transpilation.

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

JavaScript and TypeScript Bundling

This feature allows you to bundle multiple JavaScript or TypeScript files into a single file. The code sample demonstrates how to bundle an entry file named 'app.js' into an output file named 'out.js'.

require('esbuild').build({
  entryPoints: ['app.js'],
  bundle: true,
  outfile: 'out.js'
}).catch(() => process.exit(1))

Minification

This feature enables the minification of JavaScript files to reduce their size by removing unnecessary characters without changing their functionality. The code sample shows how to minify an entry file 'app.js' into a minified output file 'out.min.js'.

require('esbuild').build({
  entryPoints: ['app.js'],
  minify: true,
  outfile: 'out.min.js'
}).catch(() => process.exit(1))

Transpilation

This feature allows for the transpilation of TypeScript code into JavaScript, making it compatible with older browsers or environments that do not support TypeScript natively. The code sample demonstrates bundling and transpiling a TypeScript file 'app.ts' into a JavaScript file 'out.js'.

require('esbuild').build({
  entryPoints: ['app.ts'],
  bundle: true,
  outfile: 'out.js',
  loader: { '.ts': 'ts' }
}).catch(() => process.exit(1))

Other packages similar to @esbuild/darwin-x64

webpack

Webpack is a powerful module bundler for JavaScript applications. It offers a wide range of plugins and loaders to transform, bundle, or package almost any resource or asset. Compared to @esbuild/darwin-x64, webpack is more feature-rich and configurable but generally slower in terms of build speed.

rollup

Rollup is another JavaScript module bundler that focuses on producing efficient bundles for modern module formats like ES6. It's known for its simplicity and efficiency, especially for library authors. Rollup is similar to @esbuild/darwin-x64 in terms of speed and efficiency but lacks some of the more advanced optimization features found in esbuild.

parcel

Parcel is a web application bundler that offers out-of-the-box support for many web development languages and tools without the need for configuration. It's designed to be fast, utilizing multicore processing for efficient builds. Compared to @esbuild/darwin-x64, Parcel provides a more integrated development experience with less focus on manual configuration.

Changelog

0.20.1

• Fix a bug with the CSS nesting transform (#3648)

  This release fixes a bug with the CSS nesting transform for older browsers where the generated CSS could be incorrect if a selector list contained a pseudo element followed by another selector. The bug was caused by incorrectly mutating the parent rule's selector list when filtering out pseudo elements for the child rules:

  /* Original code */
  .foo {
    &:after,
    & .bar {
      color: red;
    }
  }
  
  /* Old output (with --supported:nesting=false) */
  .foo .bar,
  .foo .bar {
    color: red;
  }
  
  /* New output (with --supported:nesting=false) */
  .foo:after,
  .foo .bar {
    color: red;
  }
  

• Constant folding for JavaScript inequality operators (#3645)

  This release introduces constant folding for the < > <= >= operators. The minifier will now replace these operators with true or false when both sides are compile-time numeric or string constants:

  // Original code
  console.log(1 < 2, '🍕' > '🧀')
  
  // Old output (with --minify)
  console.log(1<2,"🍕">"🧀");
  
  // New output (with --minify)
  console.log(!0,!1);
  

• Better handling of __proto__ edge cases (#3651)

  JavaScript object literal syntax contains a special case where a non-computed property with a key of __proto__ sets the prototype of the object. This does not apply to computed properties or to properties that use the shorthand property syntax introduced in ES6. Previously esbuild didn't correctly preserve the "sets the prototype" status of properties inside an object literal, meaning a property that sets the prototype could accidentally be transformed into one that doesn't and vice versa. This has now been fixed:

  // Original code
  function foo(__proto__) {
    return { __proto__: __proto__ } // Note: sets the prototype
  }
  function bar(__proto__, proto) {
    {
      let __proto__ = proto
      return { __proto__ } // Note: doesn't set the prototype
    }
  }
  
  // Old output
  function foo(__proto__) {
    return { __proto__ }; // Note: no longer sets the prototype (WRONG)
  }
  function bar(__proto__, proto) {
    {
      let __proto__2 = proto;
      return { __proto__: __proto__2 }; // Note: now sets the prototype (WRONG)
    }
  }
  
  // New output
  function foo(__proto__) {
    return { __proto__: __proto__ }; // Note: sets the prototype (correct)
  }
  function bar(__proto__, proto) {
    {
      let __proto__2 = proto;
      return { ["__proto__"]: __proto__2 }; // Note: doesn't set the prototype (correct)
    }
  }
  

• Fix cross-platform non-determinism with CSS color space transformations (#3650)

  The Go compiler takes advantage of "fused multiply and add" (FMA) instructions on certain processors which do the operation x*y + z without intermediate rounding. This causes esbuild's CSS color space math to differ on different processors (currently ppc64le and s390x), which breaks esbuild's guarantee of deterministic output. To avoid this, esbuild's color space math now inserts a float64() cast around every single math operation. This tells the Go compiler not to use the FMA optimization.

• Fix a crash when resolving a path from a directory that doesn't exist (#3634)

  This release fixes a regression where esbuild could crash when resolving an absolute path if the source directory for the path resolution operation doesn't exist. While this situation doesn't normally come up, it could come up when running esbuild concurrently with another operation that mutates the file system as esbuild is doing a build (such as using git to switch branches). The underlying problem was a regression that was introduced in version 0.18.0.
