@esbuild/linux-arm64

What is @esbuild/linux-arm64?

The @esbuild/linux-arm64 npm package is a binary package for the esbuild bundler and minifier tool. It is specifically compiled for Linux systems running on ARM64 architecture. Esbuild is a fast JavaScript bundler and minifier that compiles TypeScript, JavaScript, and JSX files into a single file for use in web applications.

What are @esbuild/linux-arm64's main functionalities?

Bundling JavaScript files

This code sample demonstrates how to bundle multiple JavaScript files into a single file using esbuild.

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

Minifying JavaScript

This code sample shows how to minify a JavaScript file, reducing its size for production deployment.

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

Transpiling TypeScript

This code sample illustrates how to transpile TypeScript files into JavaScript using esbuild.

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

Transforming JSX

This code sample demonstrates how to transform JSX syntax into JavaScript, which is useful for React applications.

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

Other packages similar to @esbuild/linux-arm64

webpack

Webpack is a popular JavaScript module bundler with a large ecosystem of plugins. It is more configurable than esbuild but generally slower due to its more complex features and plugin system.

rollup

Rollup is another module bundler that is well-suited for creating libraries and applications. It focuses on producing smaller bundles through tree-shaking, but it is not as fast as esbuild.

parcel

Parcel is a web application bundler that offers a zero-configuration setup. It is known for its ease of use and fast build times, but esbuild typically outperforms it in terms of speed.

terser

Terser is a JavaScript parser, mangler, and compressor toolkit for ES6+. It is commonly used for minifying JavaScript code, similar to esbuild's minification feature, but does not bundle files.

Changelog

0.19.12

• The "preserve" JSX mode now preserves JSX text verbatim (#3605)

  The JSX specification deliberately doesn't specify how JSX text is supposed to be interpreted and there is no canonical way to interpret JSX text. Two most popular interpretations are Babel and TypeScript. Yes they are different (esbuild deliberately follows TypeScript by the way).

  Previously esbuild normalized text to the TypeScript interpretation when the "preserve" JSX mode is active. However, "preserve" should arguably reproduce the original JSX text verbatim so that whatever JSX transform runs after esbuild is free to interpret it however it wants. So with this release, esbuild will now pass JSX text through unmodified:

  // Original code
  let el =
    <a href={'/'} title='&apos;&quot;'> some text
      {foo}
        more text </a>
  
  // Old output (with --loader=jsx --jsx=preserve)
  let el = <a href="/" title={`'"`}>
    {" some text"}
    {foo}
    {"more text "}
  </a>;
  
  // New output (with --loader=jsx --jsx=preserve)
  let el = <a href={"/"} title='&apos;&quot;'> some text
      {foo}
        more text </a>;
  

• Allow JSX elements as JSX attribute values

  JSX has an obscure feature where you can use JSX elements in attribute position without surrounding them with {...}. It looks like this:

  let el = <div data-ab=<><a/><b/></>/>;
  

  I think I originally didn't implement it even though it's part of the JSX specification because it previously didn't work in TypeScript (and potentially also in Babel?). However, support for it was silently added in TypeScript 4.8 without me noticing and Babel has also since fixed their bugs regarding this feature. So I'm adding it to esbuild too now that I know it's widely supported.

  Keep in mind that there is some ongoing discussion about removing this feature from JSX. I agree that the syntax seems out of place (it does away with the elegance of "JSX is basically just XML with {...} escapes" for something arguably harder to read, which doesn't seem like a good trade-off), but it's in the specification and TypeScript and Babel both implement it so I'm going to have esbuild implement it too. However, I reserve the right to remove it from esbuild if it's ever removed from the specification in the future. So use it with caution.

• Fix a bug with TypeScript type parsing (#3574)

  This release fixes a bug with esbuild's TypeScript parser where a conditional type containing a union type that ends with an infer type that ends with a constraint could fail to parse. This was caused by the "don't parse a conditional type" flag not getting passed through the union type parser. Here's an example of valid TypeScript code that previously failed to parse correctly:

  type InferUnion<T> = T extends { a: infer U extends number } | infer U extends number ? U : never
