Honeybadger's Webpack Source Map Plugin

Note: This repository has been moved to @honeybadger-io/js, home to all Honeybadger's JavaScript packages.

Webpack plugin to upload JavaScript sourcemaps to Honeybadger. You can also send deployment notifications.

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

Installation

npm install @honeybadger-io/webpack --save-dev

Configuration

Plugin parameters

These plugin parameters correspond to the Honeybadger Source Map Upload API and Deployments 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

endpoint (optional — default: "https://api.honeybadger.io/v1/source_maps")

Where to upload your sourcemaps to. Perhaps you have a self hosted sourcemap server you would like to upload your sourcemaps to instead of honeybadger.

revision (optional — default: "master")

The deploy revision (i.e. commit hash) 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. See the Honeybadger docs for examples.

silent (optional — default: "null/false")

If true, silence log information emitted by the plugin.

ignoreErrors (optional — default: false)

If true, webpack compilation errors are treated as warnings.

retries (optional — default: 3, max: 10)

This package implements fetch retry functionality via https://github.com/vercel/fetch-retry
Retrying helps fix issues like `ECONNRESET` and `SOCKETTIMEOUT` errors and retries on 429 and 500 errors as well.

workerCount (optional — default: 5, min: 1)

Sourcemaps are uploaded in parallel by a configurable number of workers. Increase or decrease this value to configure how many sourcemaps are being uploaded in parallel.
Limited parallelism helps with connection issues in Docker environments.

deploy (optional — default: false)

Configuration for deployment notifications. To disable deployment notifications, ignore this option. To enable deployment notifications, set this to true, or to an object containing any of these fields (see the API reference):

environment

The environment name, for example, "production"

repository

The base URL of the VCS repository (HTTPS-style), for example, "https://github.com/yourusername/yourrepo"

localUsername

The name of the user that triggered this deploy, for example, "Jane"

Vanilla webpack.config.js

const HoneybadgerSourceMapPlugin = require('@honeybadger-io/webpack')
const ASSETS_URL = 'https://cdn.example.com/assets';
const webpackConfig = {
  plugins: [new HoneybadgerSourceMapPlugin({
    apiKey: 'abc123',
    assetsUrl: ASSETS_URL,
    revision: 'master',
    // You can also enable deployment notifications:
    deploy: {
       environment: process.env.NODE_ENV,
       repository: "https://github.com/yourusername/yourrepo"
    }
  })]
}

Rails Webpacker config/webpack/environment.js

const { environment } = require('@rails/webpacker')
const HoneybadgerSourceMapPlugin = require('@honeybadger-io/webpack')

// Assumes Heroku / 12-factor application style ENV variables
// named GIT_COMMIT, HONEYBADGER_API_KEY, ASSETS_URL
const revision = process.env.GIT_COMMIT || 'master'

environment.plugins.append(
  'HoneybadgerSourceMap',
  new HoneybadgerSourceMapPlugin({
    apiKey: process.env.HONEYBADGER_API_KEY,
    assetsUrl: process.env.ASSETS_URL,
    silent: false,
    ignoreErrors: false,
    revision: revision
  }))

module.exports = environment
