Installation and Configuration

Netlify automatically detects Angular projects and sets up the latest version of this plugin.

For Angular 17 and Angular 18

There's no further configuration needed from Netlify users.

For Angular 19

If you are using Server-Side Rendering you will need to install Angular Runtime in your Angular project to be able to import required utilities to successfully deploy request handler to Netlify. See Manual Installation for installations details. See Request handling for more information about request handler.

Manual Installation

If you need to pin this plugin to a specific version or if you are using Server-Side Rendering with Angular 19, you will need to install the plugin manually.

Install it via your package manager:

npm install -D @netlify/angular-runtime
# or
yarn add -D @netlify/angular-runtime

Accessing `Request` and `Context` during Server-Side Rendering

During server-side rendering (SSR), you can access the incoming Request object and the Netlify-specific Context object via providers:

import type { Context } from "@netlify/edge-functions"

export class FooComponent {

  constructor(
    // ...
    @Inject('netlify.request') @Optional() request?: Request,
    @Inject('netlify.context') @Optional() context?: Context,
  ) {
    console.log(`Rendering Foo for path ${request?.url} from location ${context?.geo?.city}`)
    // ...
  }
  
}

Keep in mind that these will not be available on the client-side or during prerendering.

To test this in local development, run your Angular project using netlify serve:

netlify serve

App Engine Developer Preview usage with Angular@19

If you opt into the App Engine Developer Preview accessing Request and Context objects is streamlined. Instead of custom Netlify prefixed providers, you should use the standardized injection tokens for those provided by @angular/core instead:

+import { REQUEST, REQUEST_CONTEXT } from '@angular/core'
import type { Context } from "@netlify/edge-functions"

export class FooComponent {

  constructor(
    // ...
-    @Inject('netlify.request') @Optional() request?: Request,
-    @Inject('netlify.context') @Optional() context?: Context,
+    @Inject(REQUEST) @Optional() request?: Request,
+    @Inject(REQUEST_CONTEXT) @Optional() context?: Context,
  ) {
    console.log(`Rendering Foo for path ${request?.url} from location ${context?.geo?.city}`)
    // ...
  }
  
}

Request handling

Starting with Angular@19. The build plugin makes use of the server.ts file to handle requests. The default Angular scaffolding generates incompatible code for Netlify so the build plugin will swap it for compatible server.ts file automatically if it detects default version being used.

Make sure you have @netlify/angular-runtime version 2.2.0 or later installed in your project. Netlify compatible server.ts file imports utilities from this package and Angular Compiler need to be able to resolve it and it can only do that if it's installed in your project and not when it's auto-installed by Netlify.

Customizing request handling

If you need to customize the request handling, you can do so by copying one of code snippets below to your server.ts file.

If you did not opt into the App Engine Developer Preview:

import { CommonEngine } from '@angular/ssr/node'
import { render } from '@netlify/angular-runtime/common-engine'

const commonEngine = new CommonEngine()

export async function netlifyCommonEngineHandler(request: Request, context: any): Promise<Response> {
  // Example API endpoints can be defined here.
  // Uncomment and define endpoints as necessary.
  // const pathname = new URL(request.url).pathname;
  // if (pathname === '/api/hello') {
  //   return Response.json({ message: 'Hello from the API' });
  // }

  return await render(commonEngine)
}

If you opted into the App Engine Developer Preview:

import { AngularAppEngine, createRequestHandler } from '@angular/ssr'
import { getContext } from '@netlify/angular-runtime/context'

const angularAppEngine = new AngularAppEngine()

export async function netlifyAppEngineHandler(request: Request): Promise<Response> {
  const context = getContext()

  // Example API endpoints can be defined here.
  // Uncomment and define endpoints as necessary.
  // const pathname = new URL(request.url).pathname;
  // if (pathname === '/api/hello') {
  //   return Response.json({ message: 'Hello from the API' });
  // }

  const result = await angularAppEngine.handle(request, context)
  return result || new Response('Not found', { status: 404 })
}

/**
 * The request handler used by the Angular CLI (dev-server and during build).
 */
export const reqHandler = createRequestHandler(netlifyAppEngineHandler)

Limitations

The server.ts file that's part of the Angular scaffolding is meant for deploying to a VM, and is not compatible with this Netlify build plugin for Angular@17 and Angular@18. If you applied changes to that file, you'll need to replicate them in an Edge Function. See (#135)[netlify#135] for an example.

CLI Usage

Requirements

To use the Angular Runtime while building and deploying with the CLI, you need to have netlify-cli v17.0.0 installed (or a later version).

Please also make sure to use ntl deploy --build (rather than ntl build && ntl deploy).
