esbuild-plugin-elm

library0.0.12jsnpmunverified

An esbuild plugin for building Elm projects, version 0.0.12. It integrates the Elm compiler into esbuild's build process, resolving imports via elm.json source-directories. Key features include debug mode, optimization based on NODE_ENV, watch mode support with console clearing, and custom path to Elm executable. Compared to alternatives like elm-webpack-loader or elm-parcel, this plugin is tightly coupled with esbuild, offering faster builds. It depends on esbuild >=0.8.1. Release cadence is irregular, last updated in 2022.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

ElmPlugin

✓ import ElmPlugin from 'esbuild-plugin-elm'

✗ const { ElmPlugin } = require('esbuild-plugin-elm')

Default export; named export not available in CommonJS

ElmPlugin

✓ const ElmPlugin = require('esbuild-plugin-elm').default

✗ const ElmPlugin = require('esbuild-plugin-elm')

CommonJS require needs .default due to ESM default export

ElmPlugin

✓ import ElmPlugin from 'esbuild-plugin-elm'

✗ import { ElmPlugin } from 'esbuild-plugin-elm'

Named import is incorrect; it's a default export

Basic ESM usage of esbuild-plugin-elm with esbuild, showing import and configuration options.

import esbuild from 'esbuild'; import ElmPlugin from 'esbuild-plugin-elm'; await esbuild.build({ entryPoints: ['src/index.js'], bundle: true, outfile: 'dist/bundle.js', plugins: [ ElmPlugin({ debug: false, optimize: process.env.NODE_ENV === 'production', pathToElm: 'node_modules/.bin/elm', clearOnWatch: false, verbose: false, }), ], }); console.log('Build complete.');

Debug

Known issues

gotchaDefault export; named import fails

fix

Use default import: import ElmPlugin from 'esbuild-plugin-elm'

affects: >=0.0.0

gotchaCommonJS require returns ESM module; must use .default

fix

Use const ElmPlugin = require('esbuild-plugin-elm').default

affects: >=0.0.0

gotchaPath to Elm executable defaults to 'elm' in PATH; may fail if not installed globally

fix

Set pathToElm option to exact path of elm binary (e.g., require('elm'))

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: ElmPlugin is not a function

Incorrect import: const ElmPlugin = require('esbuild-plugin-elm') instead of .default

fix

const ElmPlugin = require('esbuild-plugin-elm').default

Error: Plugin 'elm' failed: elm: command not found

Elm compiler not installed or not in PATH

fix

Install elm globally or set pathToElm option to full path of elm executable

error: No matching entry point found for 'src/Main.elm'

Entry point file extension not recognized; use .js or .ts as entry, not .elm

fix

Use a JavaScript/TypeScript file as entry point that imports Elm modules
