rollup-plugin-extensions

library0.1.0jsnpmunverified

A Rollup plugin that resolves local files with custom extensions (e.g., .tsx, .ts, .jsx). Version 0.1.0 is the only release; it is in early development with no test suite. Unlike rollup-plugin-node-resolve, it avoids resolving node_modules entirely, focusing solely on adding extension support for local imports. It is primarily intended for building packages where you control the dependency graph, and it automatically resolves index files based on the provided extensions.

Code

Verified usage

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

default

✓ import extensions from 'rollup-plugin-extensions'

✗ import { extensions } from 'rollup-plugin-extensions'

The package exports a default function; named import will give undefined.

default

✓ const extensions = require('rollup-plugin-extensions')

✗ const { extensions } = require('rollup-plugin-extensions')

CommonJS require works but destructure fails.

default

✓ import extensions = require('rollup-plugin-extensions')

TypeScript with legacy module resolution.

Shows a basic Rollup configuration using rollup-plugin-extensions to resolve TypeScript and JSX files locally.

// rollup.config.js import extensions from 'rollup-plugin-extensions'; export default { input: 'src/index.ts', output: { file: 'dist/bundle.js', format: 'cjs', }, plugins: [ extensions({ extensions: ['.ts', '.tsx', '.js', '.jsx'], resolveIndex: true, }), ], }; // Now you can import './foo.ts' without specifying the extension in the source code.

Debug

Known issues

gotchaDefault extensions are ['.mjs', '.js']; if you need TypeScript, you must specify extensions explicitly.

fix

Provide an extensions array with desired extensions.

affects: 0.1.0

gotchaThis plugin does NOT resolve node_modules; it only resolves local imports. Using it together with rollup-plugin-node-resolve may cause unexpected behavior.

fix

Avoid combining with rollup-plugin-node-resolve unless you understand the conflict.

affects: 0.1.0

gotchaNo test suite exists; the plugin may have undiscovered bugs.

fix

Use with caution and test your build thoroughly.

affects: 0.1.0

gotchaThe plugin only handles relative imports (starting with './' or '../'). Absolute imports are not transformed.

fix

Use another plugin like rollup-plugin-alias for absolute imports.

affects: 0.1.0

Errors

Common errors & fixes

TypeError: extensions is not a function

Imported the plugin as a named export instead of default.

fix

Change import to import extensions from 'rollup-plugin-extensions'.

Error: Could not resolve './foo' from src/index.ts

Extension not included in the plugin's extensions list.

fix

Add the missing extension (e.g., '.ts') to the extensions array in the plugin configuration.

Module not found: Error: Can't resolve './bar' in '/path/to/project'

The plugin is not installed or not applied in rollup config.

fix

Install the plugin (yarn add -D rollup-plugin-extensions) and add it to the plugins array.
