Why Migrate Now

Get off AngularJS before the risk catches up with you

AngularJS 1.x was a pioneering framework. It brought data binding, dependency injection, and single-page application architecture to the mainstream. But Google discontinued it on 31 December 2021. No security patches. No bug fixes. No updates.

If your application still runs on AngularJS, you are operating on an unsupported framework with known vulnerabilities that will never be patched. The developer talent pool is shrinking. Performance is limited by architectural decisions made a decade ago.

We migrate AngularJS applications to React, Angular (modern), or Vue. The migration is incremental: both frameworks run side-by-side while components are migrated one at a time. Your application stays functional throughout. No downtime, no big-bang risk.

Migration Options

Move to React, Angular or Vue, or rebuild

React, Angular, Vue, or a complete rebuild. Each option has different strengths. We recommend based on your team, codebase, and business context.

AngularJS → React Migration

React is the most common migration target for AngularJS applications. Component-based architecture, massive ecosystem, and the largest developer talent pool. If your team knows JavaScript and you want maximum flexibility in hiring, React is the safe choice.

We migrate AngularJS applications to React component by component. During the transition, both frameworks run side-by-side in the same application using a micro-frontend approach or ngReact bridging. Your users do not notice the migration is happening.

AngularJS → Angular (2+) Migration

Angular (the modern version, 2+) is TypeScript-first, opinionated, and provides a complete framework out of the box: routing, forms, HTTP, testing, and CLI. If your team likes the structured approach AngularJS offered, modern Angular preserves that philosophy.

Despite sharing the "Angular" name, AngularJS and modern Angular are fundamentally different frameworks. The migration is essentially a rewrite. AngularJS controllers, $scope, directives, and services do not map directly to Angular components, decorators, and dependency injection.

AngularJS → Vue Migration

Vue is the gentlest migration path from AngularJS. The syntax is more familiar: templates with directives, two-way binding, and a similar mental model. Developers who know AngularJS typically pick up Vue faster than React or Angular.

Vue 3 with the Composition API and TypeScript support. Vue Router, Pinia for state management, and Vite for build tooling. A lighter footprint than Angular with more structure than React. Good for teams that want guidance without heavy framework opinions.

Complete Application Rebuild

Sometimes an incremental migration is not practical. The AngularJS codebase is too messy, the application needs significant feature changes, or the backend also needs replacing. In these cases, a clean rebuild on a modern framework is faster and cheaper.

We scope the rebuild based on what the application actually needs to do, not on what the existing code looks like. Features are prioritised, an MVP is defined, and the new application is built from scratch. The old AngularJS app runs until the new one is ready.

API Extraction & Backend Modernisation

Many AngularJS applications have the frontend and backend tangled together: server-rendered templates mixed with AngularJS directives, business logic in the frontend, and API endpoints that were designed for the AngularJS app rather than as a proper API.

We separate the frontend from the backend. A clean REST or GraphQL API serves the frontend. The frontend is a standalone single-page application (React, Angular, or Vue) that consumes the API. Backend and frontend can evolve independently.

Why Migrate

No security patches, fewer developers, slower screens

AngularJS is end-of-life with no security patches

AngularJS (1.x) reached end-of-life on 31 December 2021. Google no longer provides security patches, bug fixes, or updates. The extended long-term support (LTS) from HeroDevs is available but is a paid commercial service, and it only buys time, not a permanent solution.

Running an end-of-life framework means known vulnerabilities will not be patched. If a security issue is discovered in AngularJS, there is no fix coming from Google. For applications handling customer data, financial information, or personal data, this is a compliance risk.

The clock is ticking. Every month without migrating increases the risk of a security incident, makes the eventual migration harder (as the codebase evolves), and reduces the pool of developers willing to work on AngularJS.

AngularJS developers are disappearing

Nobody is learning AngularJS in 2025. Junior developers learn React, Angular (modern), Vue, or Svelte. Senior developers with AngularJS experience are moving to modern frameworks. The talent pool is shrinking every month.

Hiring an AngularJS developer is increasingly difficult and expensive. Contractors charge a premium for legacy framework work. Agencies are less willing to take on AngularJS maintenance. Your options are narrowing.

After migration, your application is built on a framework with millions of developers worldwide. Hiring is easier, costs are lower, and you are not dependent on a shrinking pool of specialists.

Modern frameworks are dramatically faster

AngularJS uses dirty checking: it evaluates every watcher on every digest cycle. As the application grows, performance degrades. Large forms, complex lists, and data-heavy views become slow. This is an architectural limitation of AngularJS that cannot be fixed.

React (virtual DOM), Angular (change detection with zones), and Vue (reactivity system) all use fundamentally better rendering strategies. The performance difference on complex views is significant, often 5 to 10 times faster rendering.

Modern build tools (Vite, webpack 5, esbuild) produce smaller, more optimised bundles. Tree-shaking removes unused code. Code splitting loads only what the user needs. Initial load times drop dramatically.

Access to modern JavaScript ecosystem

AngularJS predates modern JavaScript (ES6+). It uses its own module system, its own dependency injection, and its own build tools. The modern JavaScript ecosystem (npm packages, TypeScript, modern build tools, testing libraries) does not integrate well with AngularJS.

After migration, your application has access to the full npm ecosystem. Component libraries, charting packages, authentication SDKs, form libraries, and thousands of utilities. Modern frameworks are built for this ecosystem.

TypeScript support is a major benefit. Static typing catches bugs at compile time, IDE autocompletion is dramatically better, and refactoring is safer. AngularJS was built before TypeScript existed.

Migration Services

What a move off AngularJS includes

From audit to handover. Incremental migration with zero downtime.

AngularJS Codebase Audit

We audit your AngularJS application: controllers, services, directives, routing, API calls, and third-party dependencies. You get a migration plan with scope, effort, and cost estimates.

Incremental Migration

Both frameworks running side-by-side. Pages migrated one at a time. Your application stays functional throughout. No big-bang cutover risk.

Security Patch (Interim)

Need to keep AngularJS running while planning the migration? We apply interim security measures: Content Security Policy, input sanitisation, and XSS protection at the server level.

API Modernisation

Backend API cleaned up during the frontend migration. RESTful design, proper authentication, versioning, and documentation. The API serves the new frontend and future mobile apps.

Testing & QA

Automated tests written during migration: unit tests, integration tests, and end-to-end tests. The migrated application is tested more thoroughly than the original.

Team Training

Your development team trained on the new framework. Code reviews, pair programming, and documentation so your team can maintain the migrated application independently.

Common Scenarios

Portals, products and internal apps stuck on AngularJS

If one of these sounds like your situation, we can help.

01

Internal Business Application

AngularJS dashboard, admin panel, or business tool used internally. Security risk from EOL framework. Migration to React or Vue for continued development.

02

Customer-Facing Portal

Customer portal or self-service app built on AngularJS. Performance issues and security concerns driving migration. Need to maintain uptime during transition.

03

SaaS Product

B2B SaaS product with AngularJS frontend. Customers noticing performance issues. Developer recruitment increasingly difficult. Strategic migration to modern stack.

04

Security Compliance Requirement

Audit or compliance review flagged the end-of-life AngularJS framework. Migration required to meet security standards or customer requirements.

05

Developer Left

AngularJS developer moved on. Nobody on the team knows AngularJS. Need someone to take over and migrate to a framework the team can support.

06

Performance Issues

Large AngularJS application hitting performance limits. Slow rendering, sluggish forms, and poor mobile experience. Migration for architectural performance improvement.

How It Works

Migrate screen by screen while the app stays live

Incremental migration. Both frameworks running side-by-side. Your users do not notice the transition.

  1. 1. Audit & Framework Selection

    We audit the AngularJS codebase: size, complexity, test coverage, API dependencies, and third-party libraries. Based on the findings and your team's skills, we recommend React, Angular, or Vue as the migration target.

  2. 2. Side-by-Side Setup

    Both AngularJS and the target framework running in the same application. New framework handles new routes, AngularJS handles existing routes. The bridge allows gradual migration without downtime.

  3. 3. Component Migration (Iterative)

    Pages and components migrated one at a time, starting with the simplest. Each migrated component is tested and deployed before moving to the next. Your users see gradual improvements, not a risky big-bang switch.

  4. 4. Shared State & Services

    AngularJS services and shared state migrated to the new framework. Authentication, API clients, and application state work across both the old and new components during the transition.

  5. 5. AngularJS Removal

    Once all components are migrated, AngularJS is removed from the application. The bridging code is cleaned up. The application runs entirely on the modern framework.

  6. 6. Optimisation & Handover

    Performance optimisation, code splitting, and bundle size reduction. Documentation updated. Your team trained on the new codebase. CI/CD pipeline configured for the modern framework.

Technical Context

The modern tools your app moves onto

The frameworks and tools we use as migration targets and during the transition process.

React

The most popular migration target. Largest ecosystem, biggest talent pool, maximum flexibility. Our default recommendation for most AngularJS migrations.

Angular (Modern)

TypeScript-first, opinionated, batteries-included. Suits teams that want a structured framework with everything built in.

Vue.js

Gentle learning curve, familiar template syntax for AngularJS developers. Good middle ground between React flexibility and Angular structure.

TypeScript

Static typing for JavaScript. Every modern migration uses TypeScript. Catches bugs at compile time and dramatically improves IDE support.

Node.js

Often the API backend for AngularJS applications. May also need updating as part of the migration.

Vite / Webpack

Modern build tools for the new frontend. Fast development, code splitting, tree shaking, and optimised production builds.

Our AngularJS application had 40 views and a security audit was breathing down our neck. HELLO PEOPLE migrated it to React over 14 weeks, incrementally, no downtime. The app is faster, the code is maintainable, and we can actually hire React developers now.

FAQs

What owners ask about leaving AngularJS

Is AngularJS really dead?

Yes. AngularJS (1.x) hit end-of-life on 31 December 2021. Google ships zero security patches or updates. Paid extended support from HeroDevs exists as a stopgap, but it's not a long-term plan. Any new vulnerability that surfaces stays unpatched by Google.

How much does an AngularJS migration cost?

It depends on scope, and we quote fixed-price after an audit. Small apps (5 to 15 views, simple forms) are the low end. Medium apps (20 to 50 views, complex state) are the middle. Large enterprise apps sit higher. The main drivers are view count, business-logic complexity, and quality of the existing code.

How long does the migration take?

About 6 to 10 weeks for small apps, 10 to 20 weeks for medium apps, and 20+ weeks for large ones. Because migration is incremental, the app keeps working the whole time. Zero downtime, no big-bang cutover.

Can we keep AngularJS running while we migrate?

Yes. Both frameworks run side by side. We migrate pages one at a time, and users keep using the app normally. The transition is invisible to them.

Should we migrate to React, Angular, or Vue?

React for the largest talent pool and hiring flexibility. Angular for a structured, opinionated framework your team can grow into. Vue if your developers know AngularJS and want the gentlest learning curve. We look at your team, codebase, and roadmap, then recommend one.

What about our backend, does that need to change?

Usually not much. If the backend exposes a REST API, the new frontend consumes the same endpoints. We might clean the API up during migration (auth, docs, endpoint hygiene), but the business logic stays.

Can our in-house team do the migration themselves?

Yes, if they know the target framework. We also offer a hybrid: we set up the migration architecture, migrate the first few components as a reference, and your team handles the rest with us on tap for support.

What happens if we do nothing?

Security risk climbs as unpatched CVEs stack up. Hiring gets harder every year. Technical debt piles up as new features get built on an EOL framework. Eventually you migrate anyway, but under time pressure, which always costs more than a planned one.
