@nx/angular:webpack-browser

Builds an Angular application using webpack.

Options can be configured in project.json when defining the executor, or when invoking it. Read more about how to configure targets and executors here: https://nx.dev/reference/project-configuration#targets.

This executor is a drop-in replacement for the @angular-devkit/build-angular:browser builder provided by the Angular CLI. It builds an Angular application using webpack.

In addition to the features provided by the Angular CLI builder, the @nx/angular:webpack-browser executor also supports the following:

Providing a custom webpack configuration
Incremental builds

Dev Server

The @nx/angular:dev-server executor is required to serve your application when using the @nx/angular:webpack-browser to build it. It is a drop-in replacement for the Angular CLI's @angular-devkit/build-angular:dev-server builder and ensures the application is correctly served with Webpack when using the @nx/angular:webpack-browser executor.

Examples

The executor supports providing a path to a custom webpack configuration. This allows you to customize how your Angular application is built. It currently supports the following types of webpack configurations:

object
Function
Promise<object|Function>

The executor will merge the provided configuration with the webpack configuration that Angular Devkit uses. The merge order is:

Angular Devkit Configuration
Provided Configuration

To use a custom webpack configuration when building your Angular application, change the build target in your project.json to match the following:

project.json
{
    ...
    "targets": {
        "build": {
            "executor": "@nx/angular:webpack-browser",
            "options": {
                ...
                "customWebpackConfig": {
                  "path": "apps/appName/webpack.config.js"
                }
            }
        },
        ...
    }
}
