Honeybadger's Webpack Source Map Plugin

CircleCI honeybadger-io/honeybadger-webpack

This is a webpack plugin to upload javascript sourcemaps to Honeybadger's API endpoint for source maps.

Word Up! to the thredUP development team for a similar webpack plugin they have authored.

Plugin parameters

These plugin parameters correspond to the Honeybadger Sourcemap API.

apiKey (required)
The API key of your Honeybadger project
assetsUrl (required)
The base URL to production assets (scheme://host/path)*wildcards are supported. The plugin combines assetsUrl with the generated minified js file name to build the API parameter minified_url
revision (optional — default: "master")
The deploy revision (i.e. commit sha) that your source map applies to. This could also be a code version. For best results, set it to something unique every time your code changes.
silent (optional — default: "null/false")
If true, silence log information emitted by the plugin.
ignoreErrors (optional — default: "null/false")
If true, webpack compilation errors are treated as warnings.
