AngularJS Legacy Support
Assess, stabilize, maintain and reduce risk in existing AngularJS 1.x applications.
AngularJS support, migration & modern Angular
Modernize the application without losing the business behind it.
Stabilize a critical AngularJS application, plan a responsible migration, or build a maintainable modern Angular frontend connected to your APIs, users and operations.
Legacy application auditPhased migration planningModern Angular delivery
Existing AngularJS
Stabilize and reduce risk
Prioritize defects, dependencies, security exposure, documentation and operational continuity.
Migration needed
Move in controlled phases
Define target architecture and migrate around validated business journeys rather than rewriting blindly.
New application
Use modern Angular
Build new work using a currently supported architecture selected for the real requirement.
Why modernization matters
Legacy frontend risk grows quietly until every change becomes expensive.
An older application can remain business-critical long after its framework and dependencies become difficult to support. The right response begins with evidence: what works, what breaks, what must remain available and what can change safely.
Reduce unsupported-framework exposureUnderstand dependencies, vulnerabilities, fragile areas and operating constraints.
Protect business continuityPlan around critical users, workflows, releases and rollback needs.
Make future changes practicalImprove architecture, testing and ownership so delivery becomes more predictable.
Turn migration into measurable progressPrioritize phases around risk reduction and useful business outcomes.
Important platform context: Official long-term support for AngularJS ended in January 2022. We support existing AngularJS applications responsibly, but recommend modern supported technologies for new development.

Phased migration strategy
A migration should preserve proven business behavior while replacing technical risk.
We assess whether stabilization, incremental replacement or a larger rebuild is appropriate. The answer depends on architecture, test coverage, dependencies, business urgency and the ability to run old and new parts together.
Dependency riskUnsupported or tightly coupled libraries.
Coverage riskImportant behavior without reliable tests.
Integration riskAPIs, identity and external systems.
Adoption riskUser workflows, training and change impact.

Modernization readiness
Resolve the unknowns before committing to a rewrite.
A reliable recommendation requires access to the code, dependency information, business-critical workflows, known issues, integrations and deployment process.

Frequently asked questions
Important details before requesting AngularJS or Angular development.
Is AngularJS still supported?
Official long-term support for AngularJS ended in January 2022. Existing applications should be assessed for risk, maintenance and migration needs.
Is AngularJS the same as modern Angular?
No. AngularJS refers to the older 1.x framework. Modern Angular is a different, actively developed framework family with a different architecture and toolchain.
Must we rewrite the whole application immediately?
Not always. The right approach may include stabilization, phased replacement or a larger rebuild depending on architecture, risks and business priorities.
Can you maintain our AngularJS application first?
Potentially, after technical assessment. Support scope depends on code quality, dependencies, environment access, risks and required outcomes.
Can you migrate AngularJS to modern Angular?
Yes, where appropriate. Migration feasibility and phasing depend on application structure, dependencies, test coverage, integrations and business continuity needs.
Can Angular connect with our existing backend?
Often yes. Feasibility depends on APIs, authentication, documentation, data contracts, permissions and the intended application behavior.
Do you provide testing and deployment support?
Yes. Scope can include suitable automated testing, release preparation, deployment coordination, monitoring and post-release support.
How long does migration take?
Timing depends on application size, complexity, dependencies, tests, integrations, team access and phasing. A realistic plan follows technical discovery.
Ready to assess the application?
Start with the code, critical workflows and risks that need a clear path.
Share your current framework, repository readiness, business-critical journeys, integrations and priorities. We can respond with a more relevant assessment or development scope.
