atlaspack

library2.0.47jsnpmunverified

Atlaspack is a blazing fast, zero-configuration web application bundler for JavaScript, TypeScript, CSS, HTML, and assets. Version 2.14.4 (latest stable) follows a rapid release cadence with frequent patch releases. It is a fork of Parcel v2 by Atlassian Labs, offering performance improvements, native Rust plugin system, and multi-threaded compilation. Key differentiators: no configuration required, built-in support for TypeScript, JSX, CSS modules, images, and fonts, with a focus on developer experience and build speed. It is ESM-only and ships TypeScript types.

Verified usage

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

Parcel

✓ import { Parcel } from 'atlaspack'

✗ const Parcel = require('atlaspack')

ESM-only since v2; use `import` not `require`

createWorkerFarm

✓ import { createWorkerFarm } from 'atlaspack'

✗ import createWorkerFarm from 'atlaspack/workers'

Exported from main entry, not subpath

config

✓ import { config } from 'atlaspack'

✗ const config = require('atlaspack').config

Named export, not default; CJS not supported

BuildError

✓ import { BuildError } from '@atlaspack/core'

✗ import { BuildError } from 'atlaspack'

BuildError moved to @atlaspack/core in v2.10+

Initializes and runs Atlaspack in production mode with a single HTML entry point and browser targets.

import { Parcel } from 'atlaspack'; const bundler = new Parcel({ entries: 'src/index.html', defaultConfig: '@atlaspack/config-default', targets: { default: { distDir: './dist', engines: { browsers: '> 0.5%, last 2 versions' } } }, mode: 'production', logLevel: 'info', profile: false, patchConsole: true }); bundler.run().then(() => { console.log('Build complete'); }).catch(err => { console.error(err); });

Known issues

breakingAtlaspack v2 is ESM-only, dropping CommonJS support.

fix

Migrate to ESM imports; use `import` instead of `require()`. If you need CJS, use bundler shims or stick to v1 (parcel).

affects: >=2.0.0

breaking`BuildError` moved from `atlaspack` to `@atlaspack/core` in v2.10.0.

fix

Change import to `import { BuildError } from '@atlaspack/core'`.

affects: >=2.10.0

deprecated`createWorkerFarm` is deprecated in favor of import from `@atlaspack/workers` directly.

fix

Use `import { WorkerFarm } from '@atlaspack/workers'` and instantiate via `new WorkerFarm()`.

affects: >=2.12.0

gotchaPlugin development requires ESM-compatible plugins; CJS plugins will not be loaded.

fix

Ensure all plugins are ESM or use dynamic import wrappers.

affects: >=2.0.0

gotchaAtlaspack's Rust-powered worker pool may cause issues on non-x86_64 architectures like ARM (e.g., Apple M1).

fix

Install matching prebuilt binaries or compile from source; check platform compatibility in docs.

affects: >=2.0.0

gotchaDefault config (`@atlaspack/config-default`) is required and must be installed explicitly as a dependency.

fix

Add `@atlaspack/config-default` to your `package.json` dependencies.

affects: >=2.0.0

Errors

Common errors & fixes

Error: Cannot find module '@atlaspack/config-default'

The default configuration package is not installed.

fix

Run `npm install @atlaspack/config-default --save-dev`.

TypeError: atlaspack__WEBPACK_IMPORTED_MODULE_0__.Parcel is not a constructor

Using CommonJS `require` instead of ESM `import`.

fix

Replace `const { Parcel } = require('atlaspack')` with `import { Parcel } from 'atlaspack'`.

Error: BuildError is not exported from atlaspack

BuildError moved to @atlaspack/core in v2.10+.

fix

Update import to `import { BuildError } from '@atlaspack/core'`.
