library0.2.6jsnpmunverified

Monopack is a JavaScript bundler designed for Node.js monorepo applications, currently in alpha (v0.2.6). It produces a single deterministic deliverable bundle (main.js), along with a filtered package.json, yarn.lock, and node_modules containing only used third-party dependencies. It targets developers using monorepos (e.g., Lerna) and CI/CD pipelines. Unlike generic bundlers like Webpack, Monopack specifically focuses on Node.js environments and deterministic builds. Release cadence is low; the project appears to be in early alpha with no recent major updates.

Code

Verified usage

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

monopack (CLI)

✓ monopack build main

✗ node monopack build main

Monopack is a CLI tool; there is no programmatic API. Use global or local installation as described.

monopack (require)

✓ const monopack = require('monopack');

✗ import monopack from 'monopack';

The package may not expose a default export; avoid ESM import if using CommonJS.

build command

✓ monopack build main.js

✗ monopack build main

Provide the entry file with extension (main.js) to avoid ambiguous resolution.

Global installation, building a monorepo app entry point to a dist directory, and running it.

// Install globally: npm install -g monopack mkdir my-monorepo-app && cd my-monorepo-app # Assumes a monorepo with a main.js entry monopack build main.js --out-dir ./dist # Output: dist/main.js, dist/package.json, dist/yarn.lock, dist/node_modules # To run immediately: monopack run main.js

monopack --version

Debug

Known issues

gotchaAlpha quality: the tool is in early alpha; may have bugs, breaking changes, or incomplete features.

fix

Use at your own risk; pin to a specific version and test thoroughly.

affects: >=0.0.0

gotchaYarn required for deterministic builds: even though the project may use npm, Yarn must be installed globally for dependency installation.

fix

Install Yarn: npm install -g yarn

affects: >=0.0.0

gotchaOnly detects static imports; dynamic require() dependencies may be missed, leading to runtime errors.

fix

Use --with-extra-module flag to manually include dynamic dependencies, e.g., monopack build main.js -m mysql

affects: >=0.0.0

gotchaNode.js >=6.14.4 required; older versions not supported.

fix

Upgrade Node.js to at least v6.14.4.

affects: >=0.0.0

gotchaLockfile must be present in project root for deterministic dependency collection.

fix

Ensure yarn.lock or package-lock.json exists in the monorepo root.

affects: >=0.0.0

Errors

Common errors & fixes

Error: Cannot find module 'monopack'

Monopack is not installed locally or globally.

fix

Install monopack: npm install -g monopack (global) or npm install --save-dev monopack (local then npx monopack)

Error: Yarn must be installed to proceed.

Yarn is required for post-build installation but not found in PATH.

fix

Install Yarn globally: npm install -g yarn

Error: Dynamic require detected: ...

Monopack encountered a dynamic require() that it cannot resolve; dependency may be missing in the final bundle.

fix

Use the --with-extra-module option to manually add the dynamic dependency, e.g., monopack build main.js -m <package-name>
