library0.2.1jsnpmunverified

A Parcel 2.x transformer plugin for JSY syntax, a JavaScript superset with syntactic sugar. Current stable version is 0.2.1. It transpiles JSY files to standard JavaScript without relying on Babel, instead using the JSY compiler directly. Designed for Parcel 2.x (alpha.3.2+), it integrates as a Parcel transformer plugin, enabling JSX-like syntax and other JSY features in a Parcel build pipeline. Differentiates from Babel-based solutions by being lightweight and Parcel-native.

default export
✓ import parcelTransformerJSY from 'parcel-transformer-jsy'
✗ const parcelTransformerJSY = require('parcel-transformer-jsy')
ESM only; plugin is typically loaded by Parcel via parcel config, not imported directly in user code.
ParcelTransformerJSY
✓ import ParcelTransformerJSY from 'parcel-transformer-jsy'
✗ const { ParcelTransformerJSY } = require('parcel-transformer-jsy')
Default export is the transformer class; named export not available.
jsyOptions
✓ import jsyOptions from 'parcel-transformer-jsy/dist/config'
✗ import { jsyOptions } from 'parcel-transformer-jsy'
Options are exported from a separate entry point since v0.2.0.

Configure Parcel 2.x to use plugin for JSY files and run build.

// .parcelrc { "extends": "@parcel/config-default", "transformers": { "*.jsy": ["parcel-transformer-jsy"] } } // package.json { "scripts": { "build": "parcel build src/index.jsy" }, "devDependencies": { "parcel": "^2.0.0", "parcel-transformer-jsy": "^0.2.0" } }
