rollup-plugin-jsy-lite

library1.7.3jsnpmunverified

A Rollup plugin that transpiles JSY syntax to standard JavaScript without requiring Babel. Current stable version is 1.7.3, with a maintenance release cadence. It is part of the JSY language ecosystem, providing a lightweight alternative to Babel-based JSY transpilation by using the `@jsy-lang/jsy-lite` parser directly. Key differentiators: no Babel dependency, simple configuration, and support for multiple output formats (CJS, UMD, ESM). Suitable for projects that want to use JSY syntax with Rollup but avoid the complexity of Babel.

Verified usage

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

default

✓ import rpi_jsy from 'rollup-plugin-jsy-lite'

✗ const rpi_jsy = require('rollup-plugin-jsy-lite')

ESM-only; use import syntax.

jsy

✓ import { jsy } from 'rollup-plugin-jsy-lite'

✗ import { rpi_jsy } from 'rollup-plugin-jsy-lite'

plugin

✓ import plugin from 'rollup-plugin-jsy-lite'

Default export is the plugin function; can be imported with any name.

Example Rollup configuration using rollup-plugin-jsy-lite to transpile JSY syntax with node-resolve plugin.

import rpi_jsy from 'rollup-plugin-jsy-lite'; import resolve from '@rollup/plugin-node-resolve'; export default { input: 'src/index.jsy', output: { file: 'dist/index.js', format: 'cjs' }, plugins: [ resolve(), rpi_jsy() ] };
