rollup-plugin-onerror

library1.0.0jsnpmunverified

A Rollup plugin that runs a user-defined callback when the build encounters an error. Version 1.0.0 is the initial and only release. This is a minimal utility package with no dependencies. It differs from Rollup's built-in error handling by allowing custom side effects (e.g., logging, notifications) without altering the build's failure behavior.

Verified usage

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

onError

✓ import onError from 'rollup-plugin-onerror'

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

Package ships a CommonJS default export, not named exports. ESM import is default.

default

✓ const onError = require('rollup-plugin-onerror')

✗ const { default: onError } = require('rollup-plugin-onerror')

In CJS, require returns the default export directly.

onError

✓ import onError from 'rollup-plugin-onerror'

✗ import { onError } from 'rollup-plugin-onerror'

Named import is incorrect; it's a default export.

Basic setup: install, import as default, and pass a callback to handle build errors.

// rollup.config.js import onError from 'rollup-plugin-onerror' export default { input: 'src/index.js', output: { file: 'dist/bundle.js', format: 'es' }, plugins: [ onError((err) => { console.log('Build failed:', err.message) }) ] }

Debug

Known issues

gotchaPlugin runs callback but does not prevent Rollup from exiting with non-zero code on error.

fix

If you need to suppress exit code, use a different plugin or modify process.exitCode within the callback.

affects: 1.0.0

gotchaCallback receives the Error object directly; no additional context (e.g., plugin name, file) is provided.

fix

Access err.stack for more context. Consider wrapping the error if additional info is needed.

affects: 1.0.0

Errors

Common errors & fixes

TypeError: onError is not a function

Using named import instead of default import in ESM.

fix

Change to 'import onError from 'rollup-plugin-onerror''

Error: The hook 'onError' is not supported by rollup-plugin-onerror

Misunderstanding the plugin as a Rollup hook rather than a regular function.

fix

Use the function directly in the plugins array, not as a hook name.
