Framework
Angular development
Angular is a framework for large applications: many screens, many forms, many developers, and a long life. We build with it, and we move older AngularJS systems to a version that is still supported.

At a glance
What it is
Angular is a complete framework for building large web applications, with a strict structure that keeps many developers consistent over many years.
Problems it solves
Large business applications grow tangled over time, and teams with older AngularJS code face a framework that is no longer supported.
Who it suits
Organizations building or maintaining substantial internal or customer applications, and owners of AngularJS systems.
How to choose
Choose Angular for large applications with many screens, many developers, and a long life. Choose something lighter for small sites and quick builds.
What it means
A framework that makes decisions for you
Most front-end tools leave you to assemble the pieces. Angular arrives with them chosen: how screens are built, how forms work, how data is fetched, how the application is tested. Everyone on a team therefore builds the same way, and a new developer finds familiar ground.
That is its value on a large project and its cost on a small one. The structure takes time to learn and adds code that a simple site does not need. On an application with dozens of screens, hundreds of form fields, and ten developers over five years, the same structure saves far more than it costs.
It also explains why Angular is common inside large organizations, in finance, healthcare, and manufacturing. Consistency across teams and over time is worth more to them than speed on day one.
What DECHY can do
Working with Angular
Build
- Large internal applications and customer portals.
- Forms-heavy tools with clear validation and saved progress.
Move
- AngularJS to current Angular, in stages.
- Older Angular versions brought up to a supported release.
Connect
Look after
- Regular updates, as the framework releases on a fixed schedule.
- Performance and accessibility reviews.
Moving forward
Moving an AngularJS application to a supported version
AngularJS is the older generation of the framework and no longer receives updates. Moving off it is a project, not a patch.
Inventory the application
We list the screens, the shared code, the libraries, and which parts are still used.
What it produces
- Screen inventory
- Library list
Choose the route
Run both generations side by side and move screen by screen, or rebuild areas that are cheaper to replace than to convert.
What it produces
- Migration plan
Move one area at a time
Each area is rebuilt, tested against the old behavior, and released while the rest stays live.
What it produces
- Rebuilt area
- Test results
Retire the old code
When the last screen has moved, the old framework and its libraries are removed.
What it produces
- Clean codebase
Options
When Angular beats the lighter choices
Suits
Large applications, forms-heavy business software, many developers, and long lives.
- Trade-off
- More to learn, and more code than a small project needs.
Suits
Products that need the widest ecosystem and a very large hiring pool.
- Trade-off
- Consistency depends on the rules your team sets for itself.
Suits
Small and medium applications, and adding interactivity to existing sites.
- Trade-off
- Less structure by default for very large teams.
Suits
Content-heavy sites where most pages need little interaction.
- Trade-off
- Rich, app-like screens take more work.
Common questions
Questions about Angular
Is Angular too heavy for our project?
For a small site, probably. For a large application with many screens and developers, its structure usually pays for itself. We say honestly which you have.
Do we have to rewrite our AngularJS application?
Not all at once. Running old and new together and moving area by area is usually safer, though some parts are cheaper to rebuild.
Can Angular work with our existing back end?
Yes. It talks to any back end that offers a standard interface, so your existing services and databases can stay.
Is Angular good for search visibility?
It can be, with server-side rendering for public pages. Internal applications behind a sign-in do not need it.

Technical depth
How we build with Angular
Our engineering choices on architecture, forms and data, quality, and keeping current, written for the people who will own the system after launch.
- Feature areas split into separate modules that load only when needed, which keeps the first screen quick.
- Services hold business logic and data access, so screens stay thin.
- Strict TypeScript settings catch mistakes before the application runs.
- Reactive forms with validation rules defined in code and tested.
- A single layer for calls to the back end, with consistent error handling.
- Unit tests for logic and end-to-end tests for the main journeys.
- Automated builds that fail on type errors, test failures, and accessibility regressions.
Angular releases on a predictable schedule and supports each version for a limited time. We plan upgrades one major version at a time, so each step is small and reversible.
