Nx CLI

If you're using @nx/angular, you can use the Nx CLI together with one of our bundler plugins (such as Webpack or esbuild) to automatically upload source maps to Sentry when building your app (with nx build, for example).

Due to @nx/angular's architecture, you'll first need to configure an executor that allows registering bundler plugins. In the end, you'll be able to automatically upload source maps whenever you're creating a production build of your app.

Configure your app to upload source maps in three steps.

1. Configure project.json

Before you register the Sentry bundler plugin, first ensure that you can register plugins (such as webpack or esbuild plugins) with your current executor (or Angular builder). Typically, this is possible if you have access to a webpack.config.js or a similar configuration file. If this already is the case, skip to step 2.

If you can't register a plugin, you'll need to change the executor in your project.json to a custom executor that allows you to register it (such as @nx/angular:webpack-browser or @nx/angular:browser-esbuild).

Check out the example below: in your project.json, replace the default executor (@angular-devkit/build-angular:browser) with @nx/angular:webpack-browser:

{
  "targets": {
    "build": {
      "executor": "@nx/angular:webpack-browser",
      "options": {
        "customWebpackConfig": {
          "path": "./webpack.config.js" // path to your webpack.config.js
        },
        "sourceMap": { // enable source maps generation
            "scripts": true,
         }
        // ... other options
      },
      // ... other options
    }
  }
}

2. Register the Sentry Bundler Plugin

To upload source maps you have to configure an auth token. Auth tokens can be passed to the plugin explicitly with the authToken option, with a SENTRY_AUTH_TOKEN environment variable, or with an .env.sentry-build-plugin file in the working directory when building your project. We recommend you add the auth token to your CI/CD environment as an environment variable.

SENTRY_AUTH_TOKEN=sntrys_YOUR_TOKEN_HERE

Webpack

Install the Sentry Webpack plugin:

npm install @sentry/webpack-plugin --save-dev

Register the Sentry webpack plugin in your webpack.config.js:

const { sentryWebpackPlugin } = require("@sentry/webpack-plugin");

module.exports = {
  // ... other config above ...

  devtool: "source-map", // Source map generation must be turned on
  plugins: [
    sentryWebpackPlugin({
      org: "example-org",
      project: "example-project",
      authToken: process.env.SENTRY_AUTH_TOKEN,
    }),
  ],
};

Learn more about configuring the plugin in our Sentry webpack plugin documentation.

esbuild

Install the Sentry esbuild plugin:

npm install @sentry/esbuild-plugin --save-dev

Then, follow the official Nx documentation to register the Sentry esbuild plugin (@sentry/esbuild-plugin) in your project.json file. For example:

{
  "targets": {
    "build": {
      "executor": "@nx/angular:browser-esbuild",
      "options": {
        "plugins": [
          {
            "path": "@sentry/esbuild-plugin",
            "options": {
              "org": "example-org",
              "project": "example-project",
              "authToken": ""
            }
          }
        ]
      }
    }
  }
}

3. Upload

To upload the source maps, build your Angular application:

nx build
