@nx/angular:webpack-dev-server

The webpack-dev-server executor is very similar to the standard dev server builder provided by the Angular Devkit. It is usually used in tandem with @nx/angular:webpack-browser when your Angular application uses a custom webpack configuration.

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.

Seving an application with a custom webpack configuration

This executor should be used along with @nx/angular:webpack-browser to serve an application using a custom webpack configuration.

Your project.json file should contain a build and serve target that matches the following:

"build": {
    "executor": "@nx/angular:webpack-browser",
    "options": {
        ...
        "customWebpackConfig": {
          "path": "apps/appName/webpack.config.js"
        }
    }
},
"serve": {
    "executor": "@nx/angular:webpack-dev-server",
    "configurations": {
        "production": {
            "buildTarget": "appName:build:production"
        },
        "development": {
            "buildTarget": "appName:build:development"
        }
    },
    "defaultConfiguration": "development",
}
Nx 15 and lower use @nrwl/ instead of @nx/

Try out this interactive editor of the configuration object. Values are validated as you type and hovering over labels will give you more information.

These buttons show the config object for specific common tasks.

Options

Mixins

This type has all of the properties below, but must also match this type:
