rollup-plugin-jsy

library1.9.4jsnpmunverified

A Rollup plugin that transforms JSY (a JavaScript syntax extension/sugar) into standard JavaScript using @jsy-lang/jsy. Version 1.9.4 is current, with stable API. This plugin enables using JSY syntax in Rollup builds, supporting both ESM and CommonJS outputs. Key differentiator: it leverages JSY's concise syntax while integrating seamlessly with Rollup's plugin system, including source maps and watch mode. Alternatives like Babel require separate configuration; this plugin is purpose-built for JSY.

Code

Verified usage

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

default

✓ import jsy from 'rollup-plugin-jsy'

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

ESM-only package, CommonJS require is not supported.

jsy

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

✗ import Jsy from 'rollup-plugin-jsy'

The package exports a function as default; named export 'jsy' also available.

pluginOptions

✓ import jsy, { PluginOptions } from 'rollup-plugin-jsy'

✗ import type { PluginOptions } from 'rollup-plugin-jsy'

PluginOptions is a value export (not just type) for runtime use; TypeScript may treat it as type.

Minimal Rollup configuration using the JSY plugin to compile .jsy files.

// rollup.config.js import jsy from 'rollup-plugin-jsy'; export default { input: 'src/index.jsy', output: { file: 'dist/bundle.js', format: 'esm' }, plugins: [ jsy() // options: { include, exclude, sourceMap, etc. } ] };

Debug

Known issues

breakingPlugin output changed from object to string in version 1.0.0.

fix

Update to latest version (1.9.4) and ensure downstream code expects string output.

affects: <1.0.0

deprecatedOption 'sourceMap' renamed to 'sourcemap' in v1.2.0.

fix

Use 'sourcemap' instead of 'sourceMap' in plugin options.

affects: >=1.2.0

gotchaThe plugin only processes files with .jsy extension by default; other extensions need explicit 'include'.

fix

Use jsy({ include: ['**/*.jsy', '**/*.mjs'] }) to include additional patterns.

affects: >=1.0.0

breakingDropped support for Node.js 10 and 12 in v1.5.0.

fix

Upgrade to Node.js >=14.

affects: >=1.5.0

gotchaMust be placed before other syntax plugins (e.g., @rollup/plugin-babel) in Rollup plugins array.

fix

Order plugins as: [jsy(), babel()] to ensure JSY transforms first.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Unexpected token (Note that you need plugins to import files that are not JavaScript)

Input file has .jsy extension but Rollup does not recognize it; plugin not added or misconfigured.

fix

Add jsy plugin to rollup.config.js and ensure 'include' covers the file.

TypeError: jsy is not a function

Importing the module incorrectly (e.g., using require or wrong named import).

fix

Use `import jsy from 'rollup-plugin-jsy'` (default import) or `const jsy = require('rollup-plugin-jsy').default`.

Error: Cannot find module '@jsy-lang/jsy'

Missing peer dependency @jsy-lang/jsy.

fix

Install peer dependency: npm install @jsy-lang/jsy --save-dev (or yarn add).
