  • Select the best migration path for you individually

Consider AngularJS to Angular Migration If

Seeking long-term tech & business advancements

Concerns about AngularJS's 2021 phase-out. With Angular's regular updates every 6 months and Google's Long-Term Support LTS, we ensure your app remains functional for years and easily adjusts to new demands without starting from scratch

Facing scalability challenges. We use Angular's modular architecture and reusable, independent data components to make your system grow quickly and easily

Focused on optimizing tech performance

Performance slowdown & unexpected errors. We employ Web Workers for background tasks and server-side rendering to boost page load times, combined with TypeScript for early error detection, ensuring a swift and stable app experience

Poor user experience from app performance issues. Leveraging Angular's support for Progressive Web Apps (PWAs) and Ahead-of-Time (AOT) compilation, our app delivers a lightning-fast, reliable, and native-like experience

Aiming to cut tech expenses

Heavy reliance on paid 3rd-party tooling. With its rich suite of in-built tools like the Command Line Interface (CLI) and Integrated Development Environment (IDE), we streamline the development process without external software purchases or integrations

Creating from the ground up, using time and resources. We utilize the Angular Material UI, a pre-made design kit, to deliver rapid and user-centric designs by adding separate modules instead of starting from scratch

How To Migrate AngularJS to Angular

Transitioning from AngularJS to Angular modernizes your application and aligns with current tech standards. Based on our in-depth experience and the recommendations of Google Angular team, we offer the following time-tested and reliable migration paths. Each path meets specific application needs and scales for a smooth transition.

Rewriting from Scratch

  • When to choose: for small and medium apps
  • Pros: Rewriting may include restructuring, refactoring, redesigning your application, or removing unnecessary code. This approach is suitable when you aim to build the app differently, incorporating best practices and gaining flexibility to add new features and make significant enhancements
  • Cons: During a certain period of time you will have to maintain two versions of the app for a smooth transition. And maintaining two versions requires more time, money, management, and support efforts

Incremental Updating

  • When to choose: for upgrading large and complex applications without disrupting business operations and when you need to maintain a steady release of new features while gradually transitioning from AngularJS to Angular
  • Pros: Allows gradual, seamless replacement of old AngularJS features with new Angular ones over time, ensuring a smooth transition
  • Cons: Requires preparing and aligning your AngularJS app with Angular in advance to make the code more maintainable, decoupled, and aligned with modern development tools

For expert evaluation and optimal migration of your AngularJS app, consult a reliable software development company. The Angular experts will analyze your current software size, functionality, other specifics and make up a detailed AngularJS to Angular migration plan.

Stay Calm with No Surprise Expenses

  • You get a detailed project plan with costs associated with each feature developed
  • Before bidding on a project, we conduct a review to filter out non-essential inquiries that can lead to overestimation
  • Weekly reports help you maintain control over the budget

Don’t Stress About Work Not Being Done

  • We sign the Statement of Work to specify the budget, deliverables and the schedule
  • You see who’s responsible for what tasks in your favorite task management system
  • We hold weekly status meetings to provide demos of what’s been achieved to hit the milestones
  • Low personnel turnover rate at Belitsoft is below 12% per annum. The risk of losing key people on your projects is low, and thus we keep knowledge in your projects and save your money

Be Confident Your Secrets are Secure

  • We guarantee your property protection policy using Master Service Agreement, Non-Disclosure Agreement, and Employee Confidentiality Contract signed prior to the start of work
  • Your legal team is welcome to make any necessary modifications to the documents to ensure they align with your requirements
  • We also implement multi-factor authentication and data encryption to add an extra layer of protection to your sensitive information while working with your software

No Need to Explain Twice

  • With minimal input from you and without overwhelming you with technical buzzwords, your needs are converted into a project requirements document any engineer can easily understand. This allows you to assign less technical staff to a project on your end, if necessary
  • Our communication goes through your preferred video/audio meeting tools like Microsoft Teams and more

Mentally Synced With Your Team

  • Commitment to business English proficiency enables the staff of our offshore software development company to collaborate as effectively as native English speakers, saving you time
  • We create a hybrid composition with engineers working in tandem with your team members
  • Work with individuals who comprehend US and EU business climate and business requirements

Frequently Asked Questions

AngularJS framework stops being supported. And if you decide to add new features or upgrade your AngularJS-based app, you may struggle to find the right specialist. The reason is developers hone their skills at new technologies to stay in demand. And few developers are now able to work with old technologies like AngularJS.

Is Angular and AngularJS the same?

AngularJS is the name for all 1.x versions of Angular released before 2018. While Angular is the name for all Angular 2.x versions of today and tomorrow. AngularJS is a feature-rich framework. However, as with any old technology, AngularJS falls behind more up-to-date frameworks, such as Angular.

Except for the listed rewriting and incremental updating, there are less researched migration paths. The Google team cannot confirm that these solutions are well-used or still maintained. So they recommend proceeding with caution.

TIP! Try ngMigration Assistant to check which migration path is your go-to option. For that, this tool scans your AngularJS application and provides a stats report.
