esbuild for Linux s390x

0.15.18 verified Sat Apr 25 auth: no javascript

This is the Linux IBM Z 64-bit Big Endian binary for esbuild, a JavaScript bundler and minifier. It is a platform-specific package automatically installed when you install esbuild on a Linux s390x machine. The current stable version of esbuild is 0.28.0, with a rapid release cadence (multiple minor/patch versions per month). esbuild differentiates from other bundlers (like webpack or Rollup) by its extreme speed, written in Go, and zero configuration by default. This package is not meant to be directly installed by users; instead, the main esbuild package selects the appropriate platform binary.

Common errors

error Error: Cannot find module 'esbuild-linux-s390x' ↓

cause Installed esbuild-linux-s390x directly instead of main esbuild package.

fix

Install the main esbuild package: npm install esbuild

error error: No matching binary for platform linux-s390x (node v...) ↓

cause esbuild platform detection failed, possibly due to a bug in older version.

fix

Update esbuild to latest version (>=0.15.0) which added s390x support.

error TypeError: esbuild.build is not a function ↓

cause Attempting to import from esbuild-linux-s390x directly.

fix

Import from 'esbuild' instead.

Warnings

gotcha Do NOT install esbuild-linux-s390x directly; it is automatically included by the main esbuild package. ↓

fix Install esbuild instead: npm install esbuild

breaking esbuild v0.27.0 introduced breaking changes. Pin exact version to avoid surprises. ↓

fix Use exact version in package.json: "esbuild": "0.27.0"

deprecated Some older APIs (like transformSync) are deprecated in favor of async equivalents. ↓

fix Use async API: await esbuild.build() instead of esbuild.buildSync()

gotcha On non-s390x Linux, the main esbuild package will select a different binary (e.g., esbuild-linux-x64). The s390x binary is only used on IBM Z systems. ↓

fix No action needed; it's handled automatically.

Install

npm install esbuild-linux-s390x

yarn add esbuild-linux-s390x

pnpm add esbuild-linux-s390x

Imports

esbuild
wrong
```
import esbuild from 'esbuild-linux-s390x'
```
correct
```
import esbuild from 'esbuild'
```
Do NOT import from the platform-specific package. Always import from the main 'esbuild' package.
build
wrong
```
require('esbuild-linux-s390x').build({...})
```
correct
```
await esbuild.build({...})
```
The main esbuild package exports the API; platform binary is selected automatically.
transform
```
await esbuild.transform(code, {...})
```
Use named function from main package.

const v = require('esbuild-linux-s390x/package.json').version

correct

esbuild.version

Access version from main package's exported property.

Quickstart

Shows how to bundle an entry point using the main esbuild package. The platform binary is selected automatically.

const esbuild = require('esbuild');

async function run() {
  const result = await esbuild.build({
    entryPoints: ['app.js'],
    bundle: true,
    outfile: 'out.js',
  });
  console.log('Build succeeded:', result);
}

run().catch(console.error);
