What is @esbuild/linux-arm?
The @esbuild/linux-arm package is a binary package for the esbuild bundler optimized for Linux ARM architecture. Esbuild is an extremely fast JavaScript bundler and minifier. It compiles TypeScript and JavaScript into highly optimized code, significantly reducing the size and improving the performance of web applications. The @esbuild/linux-arm package specifically targets devices running on ARM processors, such as Raspberry Pi, making it an ideal choice for development in ARM-based environments.
What are @esbuild/linux-arm's main functionalities?
JavaScript and TypeScript Bundling
This feature allows you to bundle JavaScript and TypeScript files into a single file. The code sample demonstrates how to bundle an entry file 'app.js' into 'out.js', targeting specific browser versions.
require('esbuild').build({
entryPoints: ['app.js'],
bundle: true,
outfile: 'out.js',
platform: 'browser',
target: ['chrome58', 'firefox57', 'safari11', 'edge16']
}).catch(() => process.exit(1))
Minification
This feature enables the minification of JavaScript files, reducing their size for production. The code sample shows how to minify an entry file 'app.js' into 'out.min.js'.
require('esbuild').build({
entryPoints: ['app.js'],
minify: true,
outfile: 'out.min.js'
}).catch(() => process.exit(1))
CSS Bundling and Minification
Esbuild can also bundle and minify CSS files. This code sample demonstrates bundling and minifying a CSS file 'app.css' into 'out.css'.
require('esbuild').build({
entryPoints: ['app.css'],
bundle: true,\n minify: true,
outfile: 'out.css'
}).catch(() => process.exit(1))
Other packages similar to @esbuild/linux-arm
webpack
Webpack is a powerful module bundler for JavaScript applications. It offers a wide range of plugins and loaders, allowing for a highly customizable build process. Compared to @esbuild/linux-arm, webpack is more feature-rich but significantly slower in terms of build time.
rollup
Rollup is another JavaScript module bundler that focuses on producing smaller bundles by eliminating unused code. It is particularly well-suited for libraries and applications using ES modules. While Rollup offers a simpler configuration and efficient bundling, esbuild outperforms it in terms of speed.
parcel
Parcel is a web application bundler that offers out-of-the-box support for many file types without the need for configuration. It provides a fast build time similar to esbuild, but esbuild typically has the edge in performance, especially for larger projects.
0.24.0
This release deliberately contains backwards-incompatible changes. To avoid automatically picking up releases like this, you should either be pinning the exact version of esbuild
in your package.json
file (recommended) or be using a version range syntax that only accepts patch upgrades such as ^0.23.0
or ~0.23.0
. See npm's documentation about semver for more information.

Drop support for older platforms (#3902)
This release drops support for the following operating system:
This is because the Go programming language dropped support for this operating system version in Go 1.23, and this release updates esbuild from Go 1.22 to Go 1.23. Go 1.23 now requires macOS 11 Big Sur or later.
Note that this only affects the binary esbuild executables that are published to the esbuild npm package. It's still possible to compile esbuild's source code for these older operating systems. If you need to, you can compile esbuild for yourself using an older version of the Go compiler (before Go version 1.23). That might look something like this:
git clone https://github.com/evanw/esbuild.git
cd esbuild
go build ./cmd/esbuild
./esbuild --version

Fix class field decorators in TypeScript if useDefineForClassFields
is false
(#3913)
Setting the useDefineForClassFields
flag to false
in tsconfig.json
means class fields use the legacy TypeScript behavior instead of the standard JavaScript behavior. Specifically they use assign semantics instead of define semantics (e.g. setters are triggered) and fields without an initializer are not initialized at all. However, when this legacy behavior is combined with standard JavaScript decorators, TypeScript switches to always initializing all fields, even those without initializers. Previously esbuild incorrectly continued to omit field initializers for this edge case. These field initializers in this case should now be emitted starting with this release.
-
Avoid incorrect cycle warning with tsconfig.json
multiple inheritance (#3898)
TypeScript 5.0 introduced multiple inheritance for tsconfig.json
files where extends
can be an array of file paths. Previously esbuild would incorrectly treat files encountered more than once when processing separate subtrees of the multiple inheritance hierarchy as an inheritance cycle. With this release, tsconfig.json
files containing this edge case should work correctly without generating a warning.

Handle Yarn Plug'n'Play stack overflow with tsconfig.json
(#3915)
Previously a tsconfig.json
file that extends
another file in a package with an exports
map could cause a stack overflow when Yarn's Plug'n'Play resolution was active. This edge case should work now starting with this release.
-
Work around more issues with Deno 1.31+ (#3917)
This version of Deno broke the stdin
and stdout
properties on command objects for inherited streams, which matters when you run esbuild's Deno module as the entry point (i.e. when import.meta.main
is true
). Previously esbuild would crash in Deno 1.31+ if you ran esbuild like that. This should be fixed starting with this release.
