parcel-plugin-jsy

library0.2.1jsnpmunverified

A Parcel 1.x plugin that transpiles JSY syntax to standard JavaScript without requiring Babel. Current stable version 0.2.1. JSY is a superset of JavaScript with simplified syntax (e.g., trailing commas, optional semicolons, and concise arrow functions). This plugin integrates JSY directly into the Parcel bundling pipeline, replacing the traditional Babel toolchain for JSY projects. It is specific to Parcel 1.x (parcel-bundler peer dependency) and is not compatible with Parcel v2. Published under the MIT license, it has limited maintenance frequency.

Code

Verified usage

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

default (plugin registration)

✓ // Package works via Parcel plugin resolution automatically

✗ const parcelPluginJsy = require('parcel-plugin-jsy');

This is a Parcel 1.x plugin; it is automatically loaded when installed. No explicit import or require is needed.

package.json

✓ "devDependencies": { "parcel-plugin-jsy": "^0.2.1" }

✗ "dependencies": { "parcel-plugin-jsy": "^0.2.1" }

Best practice: install as devDependency since it's a build-time tool.

Parcel bundler usage

✓ parcel build index.html

✗ parcel-plugin-jsy build index.html

The plugin is invoked automatically by Parcel; no separate CLI command.

Demonstrates installing the required dependencies, writing a simple JSY file, and building it with Parcel 1.x.

// 1. Install dependencies npm install --save-dev parcel-bundler@^1.12.4 parcel-plugin-jsy@^0.2.1 // 2. Create a JSY file (e.g., app.jsy) // JSY example: const add = (a, b) -> a + b console.log add(1, 2) // 3. Create an HTML file that references app.jsy // <!DOCTYPE html> // <html><body><script src="app.jsy"></script></body></html> // 4. Build with Parcel // npx parcel build index.html

Known issues

deprecatedparcel-plugin-jsy is only compatible with Parcel 1.x (parcel-bundler). It does not work with Parcel v2.

fix

If using Parcel v2, consider alternatives or use JSY with a different bundler.

affects: >=0.0.0

breakingThe plugin requires peer dependency parcel-bundler@^1.12.4. Installing with a different version will cause errors or unexpected behavior.

fix

Ensure you have parcel-bundler@^1.12.4 installed: npm install --save-dev parcel-bundler@^1.12.4

affects: >=0.0.0

gotchaparcel-plugin-jsy auto-registers as a plugin; do not attempt to import or require it explicitly in your code. Doing so may cause runtime errors.

fix

Only add the package as a dependency; Parcel will discover it automatically.

affects: >=0.0.0
