Angular Migration
Master AngularJS to Angular migration, including hybrid apps, component conversion, dependency injection changes, and routing migration.
When to Use This Skill
- Migrating AngularJS (1.x) applications to Angular (2+)
- Running hybrid AngularJS/Angular applications
- Converting directives to components
- Modernizing dependency injection
- Migrating routing systems
- Updating to latest Angular versions
- Implementing Angular best practices
Migration Strategies
1. Big Bang (Complete Rewrite)
- Rewrite entire app in Angular
- Parallel development
- Switch over at once
- Best for: Small apps, green field projects
2. Incremental (Hybrid Approach)
- Run AngularJS and Angular side-by-side
- Migrate feature by feature
- ngUpgrade for interop
- Best for: Large apps, continuous delivery
3. Vertical Slice
- Migrate one feature completely
- New features in Angular, maintain old in AngularJS
- Gradually replace
- Best for: Medium apps, distinct features
Hybrid App Setup
typescript
// main.ts - Bootstrap hybrid app
import { platformBrowserDynamic } from "@angular/platform-browser-dynamic";
import { UpgradeModule } from "@angular/upgrade/static";
import { AppModule } from "./app/app.module";
platformBrowserDynamic()
.bootstrapModule(AppModule)
.then((platformRef) => {
const upgrade = platformRef.injector.get(UpgradeModule);
// Bootstrap AngularJS
upgrade.bootstrap(document.body, ["myAngularJSApp"], { strictDi: true });
});typescript
// app.module.ts
import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { UpgradeModule } from "@angular/upgrade/static";
@NgModule({
imports: [BrowserModule, UpgradeModule],
})
export class AppModule {
constructor(private upgrade: UpgradeModule) {}
ngDoBootstrap() {
// Bootstrapped manually in main.ts
}
}Component Migration
AngularJS Controller → Angular Component
javascript
// Before: AngularJS controller
angular
.module("myApp")
.controller("UserController", function ($scope, UserService) {
$scope.user = {};
$scope.loadUser = function (id) {
UserService.getUser(id).then(function (user) {
$scope.user = user;
});
};
$scope.saveUser = function () {
UserService.saveUser($scope.user);
};
});typescript
// After: Angular component
import { Component, OnInit } from "@angular/core";
import { UserService } from "./user.service";
@Component({
selector: "app-user",
template: `
<div>
<h2>{{ user.name }}</h2>
<button (click)="saveUser()">Save</button>
</div>
`,
})
export class UserComponent implements OnInit {
user: any = {};
constructor(private userService: UserService) {}
ngOnInit() {
this.loadUser(1);
}
loadUser(id: number) {
this.userService.getUser(id).subscribe((user) => {
this.user = user;
});
}
saveUser() {
this.userService.saveUser(this.user);
}
}AngularJS Directive → Angular Component
javascript
// Before: AngularJS directive
angular.module("myApp").directive("userCard", function () {
return {
restrict: "E",
scope: {
user: "=",
onDelete: "&",
},
template: `
<div class="card">
<h3>{{ user.name }}</h3>
<button ng-click="onDelete()">Delete</button>
</div>
`,
};
});typescript
// After: Angular component
import { Component, Input, Output, EventEmitter } from "@angular/core";
@Component({
selector: "app-user-card",
template: `
<div class="card">
<h3>{{ user.name }}</h3>
<button (click)="delete.emit()">Delete</button>
</div>
`,
})
export class UserCardComponent {
@Input() user: any;
@Output() delete = new EventEmitter<void>();
}
// Usage: <app-user-card [user]="user" (delete)="handleDelete()"></app-user-card>Service Migration
javascript
// Before: AngularJS service
angular.module("myApp").factory("UserService", function ($http) {
return {
getUser: function (id) {
return $http.get("/api/users/" + id);
},
saveUser: function (user) {
return $http.post("/api/users", user);
},
};
});typescript
// After: Angular service
import { Injectable } from "@angular/core";
import { HttpClient } from "@angular/common/http";
import { Observable } from "rxjs";
@Injectable({
providedIn: "root",
})
export class UserService {
constructor(private http: HttpClient) {}
getUser(id: number): Observable<any> {
return this.http.get(`/api/users/${id}`);
}
saveUser(user: any): Observable<any> {
return this.http.post("/api/users", user);
}
}Dependency Injection Changes
Downgrading Angular → AngularJS
typescript
// Angular service
import { Injectable } from "@angular/core";
@Injectable({ providedIn: "root" })
export class NewService {
getData() {
return "data from Angular";
}
}
// Make available to AngularJS
import { downgradeInjectable } from "@angular/upgrade/static";
angular.module("myApp").factory("newService", downgradeInjectable(NewService));
// Use in AngularJS
angular.module("myApp").controller("OldController", function (newService) {
console.log(newService.getData());
});Upgrading AngularJS → Angular
typescript
// AngularJS service
angular.module('myApp').factory('oldService', function() {
return {
getData: function() {
return 'data from AngularJS';
}
};
});
// Make available to Angular
import { InjectionToken } from '@angular/core';
export const OLD_SERVICE = new InjectionToken<any>('oldService');
@NgModule({
providers: [
{
provide: OLD_SERVICE,
useFactory: (i: any) => i.get('oldService'),
deps: ['$injector']
}
]
})
// Use in Angular
@Component({...})
export class NewComponent {
constructor(@Inject(OLD_SERVICE) private oldService: any) {
console.log(this.oldService.getData());
}
}Routing Migration
javascript
// Before: AngularJS routing
angular.module("myApp").config(function ($routeProvider) {
$routeProvider
.when("/users", {
template: "<user-list></user-list>",
})
.when("/users/:id", {
template: "<user-detail></user-detail>",
});
});typescript
// After: Angular routing
import { NgModule } from "@angular/core";
import { RouterModule, Routes } from "@angular/router";
const routes: Routes = [
{ path: "users", component: UserListComponent },
{ path: "users/:id", component: UserDetailComponent },
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule],
})
export class AppRoutingModule {}Additional patterns and templates
