ember-cli-swc-minifier

library2.1.2jsnpmunverified

JavaScript minification addon for Ember-CLI using esbuild (SWC under the hood). Current stable version is 2.1.2, requires Node >= 18, and is actively maintained on GitHub. It replaces ember-cli-terser or ember-cli-uglify, offering faster builds via SWC. Key differentiators: seamless Ember integration, supports modern JS only (no ES5), configurable SWC minify options, source map support, and exclusion patterns.

@nullvoxpopuli/ember-cli-swc-minifier

✓ npm install --save-dev @nullvoxpopuli/ember-cli-swc-minifier

✗ npm install --save ember-cli-swc-minifier

Package name includes scope @nullvoxpopuli; installed as devDependency.

EmberApp

✓ const app = new EmberApp(defaults, { 'ember-cli-swc-minifier': { options } });

✗ const app = new EmberApp(defaults, { minifier: { ... } });

Configuration key must be exactly 'ember-cli-swc-minifier' (string) in the options object.

Shows configuration of ember-cli-swc-minifier in ember-cli-build.js with basic options.

// ember-cli-build.js 'use strict'; const EmberApp = require('ember-cli/lib/broccoli/ember-app'); module.exports = function(defaults) { const app = new EmberApp(defaults, { 'ember-cli-swc-minifier': { enabled: true, // defaults to true for production exclude: ['vendor.js'], swc: { compress: { drop_console: true } }, }, }); return app.toTree(); };

Debug

Known issues

breakingeclsm v2 is ESM-only, dropping support for the workspace-addon and is v2-only.

fix

Ensure your Ember-CLI version supports v2 addons and Node >= 18. Remove workspace-addon references.

affects: >=2.0.0

breakingThe package name changed from 'ember-cli-swc-minifier' to '@nullvoxpopuli/ember-cli-swc-minifier'.

fix

Uninstall old package: npm remove ember-cli-swc-minifier; install new: npm install --save-dev @nullvoxpopuli/ember-cli-swc-minifier.

affects: >=2.0.0

deprecatedOption 'uglify' and 'terser' are not supported; use 'swc' instead.

fix

Use 'swc' property to pass ESBuild/SWC minification options. See swc.rs/docs.

affects: *

gotchaSource maps are disabled by default in production. Enabling via sourcemaps config in ember-cli-build.js may not work if esbuild sourcemap option is not set.

fix

Set 'sourceMap' option inside 'ember-cli-swc-minifier' config to enable source maps: { sourceMap: 'linked' }.

affects: *

gotchaExclude paths are relative to the output directory (e.g., 'assets/app.js'), not source paths.

fix

Use output filenames like 'app.js', 'vendor.js'. No leading slash.

affects: *

gotchaES5 is not supported; only modern JavaScript (ES2015+) can be minified.

fix

Ensure your Ember-CLI build targets modern browsers or transpile to ES2015+ before minification.

affects: *

Errors

Common errors & fixes

Cannot find module 'ember-cli-swc-minifier'

Package renamed to @nullvoxpopuli/ember-cli-swc-minifier in v2.

fix

Run 'npm install --save-deve @nullvoxpopuli/ember-cli-swc-minifier' and update imports/config accordingly.

TypeError: Cannot read properties of undefined (reading 'isDevelopment')

The addon expects a valid EmberApp environment; may occur if defaults not passed.

fix

Ensure ember-cli-build.js exports a function that receives 'defaults' and passes it to new EmberApp().

Error: Minification failed: ... 'esbuild' not found

Missing @nullvoxpopuli/ember-cli-swc-minifier peer dependency esbuild.

fix

Run 'npm install --save-dev esbuild'.

Error: The 'ember-cli-swc-minifier' addon does not support CommonJS

v2 addons are ESM-only; using require() in config may fail.

fix

Use 'import' syntax or ensure your ember-cli-build.js is treated as ESM (e.g., .mjs extension).
