{"id":12880,"library":"bell-on-bundler-error-plugin","title":"Bell on Bundler Error Plugin","description":"The `bell-on-bundler-error-plugin` package provides a minimalist Webpack plugin designed to alert developers to build errors by writing a bell character (ASCII `\\u0007`) to STDERR output. This mechanism allows for audible or visual terminal notifications when a Webpack build fails, without relying on external services or complex configurations. The package is currently at version 3.0.0. Given its last significant code updates date back several years (copyright 2015-2016, with GitHub showing its last actual commit around 4 years ago as of April 2025), it exists within an ecosystem that has seen considerable evolution, particularly with Webpack's major versions 4 and 5 introducing significant changes to plugin APIs. Its core differentiator is its simple, terminal-centric approach to error notification. However, due to its age and lack of recent maintenance, it may not be compatible with modern Webpack versions (v5+) or their associated plugin ecosystems, effectively rendering it abandoned for current projects.","status":"abandoned","version":"3.0.0","language":"javascript","source_language":"en","source_url":"https://github.com/senotrusov/bell-on-bundler-error-plugin","tags":["javascript","notification","bundler","build","error","bell","console"],"install":[{"cmd":"npm install bell-on-bundler-error-plugin","lang":"bash","label":"npm"},{"cmd":"yarn add bell-on-bundler-error-plugin","lang":"bash","label":"yarn"},{"cmd":"pnpm add bell-on-bundler-error-plugin","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"This is a webpack plugin and requires webpack as a peer dependency for compilation lifecycle hooks.
