Version upgrades with ng update
One major version at a time, with breaking changes fixed and tests passing at every step.
The Problem
Your Angular App Runs the Business and Sits Versions Behind
It shows up when a security review or a browser change forces the issue. The app still works, but the upgrade path looks long, and nobody wants to touch the shared modules.
01 · Versions
The app sits several major Angular versions behind.
We upgrade one major version at a time with ng update and tests.
02 · AngularJS
Old AngularJS screens still run inside a hybrid setup.
We rebuild them module by module in current Angular while users keep working.
03 · Builds
Builds are slow enough that developers avoid running them.
We move the project to the esbuild-based application builder.
04 · Modules
Shared NgModules make every change feel risky.
New work uses standalone components and signals with clear inputs and tests.
Your Angular app handles claims, orders, or approvals for hundreds of staff, and it's several major versions behind. Every upgrade guide lists breaking changes across RxJS, Angular Material, and your third-party grid. One corner still runs AngularJS through a hybrid setup nobody fully understands. Builds take long enough that developers avoid running them. Security scans flag old dependencies every quarter, and the estimate for catching up keeps growing while the backlog waits.
We start with an upgrade map: your current version, every dependency that blocks the next one, and the order to clear them. Then we move one major version at a time with ng update, run your tests at each step, and switch to the esbuild-based builder. New features use standalone components and signals, so the codebase gets simpler as it moves forward. The app stays live throughout, because nothing ships as a big-bang rewrite.
One version at a time
We follow Angular's own update path, testing at every major version instead of jumping ahead.
Faster builds
Moving to the esbuild-based application builder cuts the wait on every build and test run.
AngularJS moved in slices
Old AngularJS screens move module by module while the rest of the app keeps running.
Our Angular Development Services Process
From Upgrade Review to Release in Five Clear Steps
You see the full upgrade path and a fixed price first, then click through a staging build after every major version before we move to the next.
We read your package.json, run the Angular update guide against your versions, and look at shared modules and tests. You get the upgrade path, the dependencies that block it, and the plan that fits.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built business apps and websites for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Enterprise Teams Hire Angular Developers From Us
Enterprise Angular apps fail slowly: skipped upgrades, unclear module boundaries, and tests nobody trusts. These habits keep your app supported and your team confident.
Upgrades on Angular's schedule
Angular ships a major version about every 6 months and supports each one for 18 months. We plan upgrades around that calendar, so you stay inside the support window.
Tests before changes
If core flows lack tests, we add them before upgrading. A passing suite at every version is how you know nothing quietly broke.
Small, reviewable steps
Each version upgrade lands as its own reviewed change set. Your team can follow along and roll back one step without losing the rest.
Honest about rewrites
If rebuilding a small app costs less than upgrading it, we'll show you the numbers. If your current version is safe for now, we'll tell you before we quote.
Security fixes included
Dependency audits run at each step, and we replace packages that stopped receiving fixes. Your security team gets a list of what changed and why.
Notes for the next upgrade
Every project ends with written notes on remaining deprecations and the next version's changes. Your developers can run the following upgrade without us.

Good fit
Enterprises with a business-critical app
Your Angular app runs claims, orders, or approvals, and it's several major versions behind with a security review coming up.
Teams still running AngularJS
Your AngularJS app lost official support at the end of 2021, and you need an Angular JS development company to move it forward safely.
.NET teams short on Angular skills
You want to hire Angular developers for a defined feature set without adding permanent headcount to a .NET-heavy team.
Companies starting a new Angular app
Your organization standardized on Angular, and you need a new internal app built with standalone components and signals from day one.
Agencies with Angular clients
You've won an enterprise client on Angular and need to hire Angular JS developers or current Angular specialists under your brand.
Not a fit
No Angular requirement
You're starting a new app with a small team and no reason to use Angular. React Development Services may suit you better, and we'll help you compare honestly.
SSO and IT gate first
Your main hurdle is SSO, security review, and IT requirements for a new app. Enterprise Web Development Company covers that gate before framework work starts.
Budget under $1,300
You need one small bug fixed in an otherwise current Angular app. A freelancer will cost less than our smallest plan and can start sooner.
Full-time seats for a year
You want Angular developers embedded full time for a year or more. A staffing agency or an in-house hire fits that better than scoped project work.

Angular projects with DeveloperLook start at $1,300 for up to 2 major version upgrades on a current app. Upgrading across up to 5 versions with modern patterns and a new feature area costs $4,600, and AngularJS migrations start at $9,400. You get a fixed price after a free upgrade review.
Most Angular version upgrades take 1 to 3 weeks, depending on how many major versions you're behind and how many libraries need replacing. AngularJS migrations usually take 8 to 16 weeks for up to 20 screens, because each module is rebuilt and tested while the app stays live.
Angular development is building web apps with Angular, which ships routing, forms, an HTTP client, and testing tools in one package. Teams like it for large apps because the structure stays consistent across projects. Current Angular uses standalone components and signals, which make code simpler than older module-based apps.
Angular is free, open-source software for building web front ends, released under the MIT license. It includes the Angular CLI, which creates projects, runs builds, and applies version updates with ng update. Angular apps run in the browser and work with any back end, such as .NET, Node.js, Python, or PHP.
Angular is used mostly for large, data-heavy web apps: internal tools, admin dashboards, banking and insurance portals, and enterprise software. Its built-in forms, routing, and dependency injection suit teams where many developers share one codebase. Our Angular JS development services also cover the older AngularJS apps that still run systems like these.
Yes, Angular is developed and maintained by a team at Google, with contributions from the open-source community. Google publishes a release plan with a new major version about every 6 months, and each version gets 18 months of support. AngularJS, the older framework, stopped receiving official support at the end of 2021.
Google uses Angular for many of its own web apps, and Angular is common in banking, insurance, healthcare, and government portals. Large organizations choose it because one framework covers routing, forms, and testing, which keeps big teams consistent. Many of these companies still run AngularJS somewhere, which is why migration work is so common.
Hire Angular developers by checking how they handle upgrades, not just new screens. Ask about the last major version upgrade they ran, how they combine signals with RxJS, and how they test. When you compare Angular developers for hire through an agency, ask who writes and reviews the code. You can also hire Angular developer time for one feature first.
Yes, for most apps, but gradually. Angular's own migration schematics convert NgModules to standalone components, and signals can replace simple RxJS state one component at a time. We keep RxJS where streams fit, such as live data feeds or complex search, and we don't rewrite working code just to follow a trend.
Yes, most of our Angular work starts in code someone else wrote. We begin with the free upgrade review, add tests to core flows if they're missing, and document what we find. You keep ownership of the repository, and support runs 30 to 90 days after release, depending on your plan.
