metal-tools-build-rollup

library2.0.6jsnpmunverified

Build tool for transpiling and bundling Metal.js ES6 JavaScript files using Rollup. Version 2.0.6 is the latest stable release for the deprecated Metal.js framework. It leverages Rollup's tree-shaking and module bundling to produce optimized browser-compatible bundles. Key differentiators: designed specifically for Metal.js ecosystem, supports global variable generation for browser globals, and integrates with other Metal build tools. However, Metal.js is no longer actively maintained; users should consider migrating to modern frameworks. The package has low maintenance cadence and limited documentation.

Code

Verified usage

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

build

✓ import build from 'metal-tools-build-rollup'

✗ const build = require('metal-tools-build-rollup')

ESM-only package; CommonJS require will fail.

build

✓ import * as metalBuild from 'metal-tools-build-rollup'

✗ import metalBuild from 'metal-tools-build-rollup'

Default export is the function; namespace import is alternative.

build

✓ const build = (await import('metal-tools-build-rollup')).default

✗ const { default: build } = require('metal-tools-build-rollup')

Dynamic import for CJS-like usage.

Build a Metal.js ES6 file into an IIFE bundle with Rollup.

import build from 'metal-tools-build-rollup'; import path from 'path'; const config = { entry: path.resolve('src/index.js'), dest: path.resolve('build/bundle.js'), format: 'iife', moduleName: 'MyApp', globalName: 'myApp', sourceMap: true }; build(config).then(() => { console.log('Build complete'); }).catch(err => { console.error('Build failed:', err); });

Errors

Common errors & fixes

Error: Cannot find module 'metal-tools-build-rollup'

Package not installed or missing from node_modules.

fix

Run 'npm install metal-tools-build-rollup' or check your package.json.

SyntaxError: Cannot use import statement outside a module

Using ESM import without 'type': 'module' in package.json.

fix

Add 'type': 'module' to your package.json, or rename file to .mjs.

TypeError: build is not a function

Incorrect import: using namespace import instead of default.

fix

Use 'import build from 'metal-tools-build-rollup' instead of 'import * as build'.
