Add the @appsignal/angular and @appsignal/javascript packages to your package.json. Then, run yarn install/npm install.

You can also add these packages to your package.json on the command line:

yarn add @appsignal/javascript @appsignal/angular
npm install --save @appsignal/javascript @appsignal/angular



The default Angular integration is a class that extends the ErrorHandler class provided by @angular/core. In a new app created using @angular/cli, your app.module.ts file might include something like this:

import { ErrorHandler, NgModule } from "@angular/core";
import Appsignal from "@appsignal/javascript";
import { createErrorHandlerFactory } from "@appsignal/angular";
const appsignal = new Appsignal({
  // other properties
  providers: [
      provide: ErrorHandler,
      useFactory: createErrorHandlerFactory(appsignal),
  // other properties
export class AppModule {}
