wrollup

library0.3.1jsnpmunverified

A simple file watcher for Rollup, designed to automatically rebuild bundles when source files change. Version 0.3.1 (last updated ~2018) is the current stable release. It is a lightweight alternative to rollup-watch, offering automatic recovery from errors and a clean logging interface. It watches a Rollup config file and triggers rebuilds, with options for caching, verbose output, and custom error glob patterns. Suitable for development workflows with Rollup, but note it is unmaintained and relies on older Rollup API patterns.

Verified usage

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

wrollup

✓ const wrollup = require('wrollup')

✗ import wrollup from 'wrollup'

The package is CommonJS only. As of v0.3.1, there is no default ESM export.

cli

✓ npx wrollup --help

✗ wrollup

The package is primarily used as a CLI tool. The CLI is the main interface; programmatic API is undocumented.

watchConfig

✓ wrollup({ config: 'rollup.config.js' })

The programmatic API takes an options object with config file path. This is inferred from source code.

Shows installation and basic CLI usage to watch a Rollup config file for changes, with dependency installation.

npm install --save-dev rollup wrollup # create rollup.config.js (see README) # run: npx wrollup -c rollup.config.js # Or add to package.json scripts: # "watch": "wrollup -c rollup.config.js" # Note: This package is outdated; consider using rollup --watch instead.

Debug

Known issues

deprecatedwrollup is unmaintained and may not work with modern Rollup versions (>=1.0.0). The project has not been updated since 2018.

fix

Use Rollup's built-in --watch flag: rollup -c --watch

affects: >=0.3.1

gotchawrollup depends on the 'rollup' package being installed separately as a peer. Missing rollup will cause a runtime error.

fix

Ensure rollup is installed: npm install --save-dev rollup

affects: >=0.0.0

breakingwrollup expects Rollup config files that export a plain object (not an array or async function). It does not support Rollup's config array or promise feature added in Rollup 1.x.

fix

If your config uses an array or async function, use Rollup's built-in watch instead.

affects: >=0.3.1

Errors

Common errors & fixes

Error: Cannot find module 'rollup'

Missing rollup peer dependency

fix

npm install --save-dev rollup

Error: Could not resolve config file rollup.config.js

Config file not found or wrong path

fix

Use -c option to specify path: wrollup -c path/to/config.js

TypeError: wrollup is not a function

Programmatic use with ES import instead of require

fix

Use const wrollup = require('wrollup'); (the package is CJS only)
