library1.6.3jsnpmunverified

Parcel is a web application bundler that offers zero configuration, out-of-the-box support for JS, CSS, HTML, and assets, automatic transforms via Babel/PostCSS/PostHTML, and built-in code splitting and hot module replacement. This package (v1.6.3) is the legacy v1 series; the current stable is Parcel v2. Key differentiators: zero-config setup, fast multicore compilation, filesystem caching, and a friendly error experience. Release cadence: maintained but legacy.

Install & Compatibility

No compatibility data collected yet for this library.

Code

Verified usage

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

Bundler

✓ const Bundler = require('parcel-bundler');

✗ import Bundler from 'parcel-bundler'; // Only CJS supported in v1

Parcel v1 is CommonJS-only. For ESM import, use Parcel v2 with 'parcel' package.

CLI usage

✓ parcel index.html

✗ parcel build index.html --no-minify // v1 CLI differs from v2; use --no-minify only in v1

CLI flags changed in v2 (e.g., --no-minify -> --no-optimize). Check docs.

Middleware

✓ const Bundler = require('parcel-bundler'); const bundler = new Bundler('index.html'); app.use(bundler.middleware());

✗ app.use(require('parcel-bundler').middleware()); // Need to instantiate Bundler first

Middleware must be created from a Bundler instance, not the class directly.

Initialize a new project, install parcel-bundler, create a minimal HTML/JS entry point, and serve it with the dev server.

mkdir my-project && cd my-project npm init -y npm install --save-dev parcel-bundler mkdir src && echo '<html><body><script src="./index.js"></script></body></html>' > src/index.html echo 'console.log("Hello Parcel");' > src/index.js npx parcel src/index.html --open

Debug

Known issues

gotchaParcel v1 uses CommonJS (require) only; import statements will fail without a transpiler.

fix

Use require() or switch to Parcel v2 which supports ESM natively.

affects: >=1.0.0 <2.0.0

deprecatedparcel-bundler is the legacy v1 package; new projects should use 'parcel' (v2) instead.

fix

Replace 'parcel-bundler' with 'parcel' in your dependencies and update your API usage.

affects: >=1.0.0

gotchaNode.js >=6.0.0 required; newer Node features may need a Babel config.

fix

Ensure Node version compatibility or add a .babelrc to transpile modern syntax.

affects: >=1.0.0

breakingParcel v1's CLI options changed significantly in v2 (e.g., --out-dir vs -d, --public-url).

fix

Refer to Parcel v1 documentation for CLI flags; when upgrading to v2, use the new CLI syntax.

affects: >=1.0.0 <2.0.0

gotchaHot module replacement in v1 requires specific configuration for frameworks like React; not automatic.

fix

Install and configure @parcel/transformer-react-refresh-wrap or similar for HMR in React.

affects: >=1.0.0 <2.0.0

deprecatedThe built-in development server can only run one instance per project; use a dedicated dev server for complex setups.

fix

For advanced use, run parcel watch separately or use Parcel v2's improved server.

affects: >=1.0.0 <2.0.0

Errors

Common errors & fixes

Cannot find module 'parcel-bundler'

Package not installed or installed globally but project uses local install.

fix

Run: npm install --save-dev parcel-bundler

TypeError: Cannot read property 'prototype' of undefined

Using ESM import syntax with CommonJS-only bundler.

fix

Use require() instead of import: const Bundler = require('parcel-bundler');

Error: Could not find entry file 'index.html'

Entry file path is relative to the current working directory, not the project root.

fix

Specify the full relative path: parcel src/index.html
