Real TypeScript Challenges. Real Solutions.

Every enterprise TypeScript project faces the same three obstacles. Here is how our team solves each one — with strict mode, shared type contracts, and a clear path from typed API platform to Flutter mobile app.

01
The Problem

JavaScript Codebase Too Risky to Refactor or Scale

Plain JavaScript codebases above 20,000 lines become increasingly dangerous to change. A function's expected inputs and outputs exist only in the original developer's memory or in out-of-date comments. Every refactor risks breaking code in unexpected locations. New developers spend weeks understanding implicit data shapes. Production incidents from runtime type errors become routine.

01
Our Solution

TypeScript Migration — Type Safety Restored, Refactoring Made Safe

We migrate JavaScript codebases to TypeScript incrementally — keeping your application running throughout. Business logic is typed first, then API boundaries, then data models. Each sprint delivers a measurable increase in type coverage. Within 12 weeks, your team refactors with confidence — the TypeScript compiler catches breaking changes before they reach production. The same typed API contracts then power the mobile app when your users need it.

02
The Problem

API Integration Bugs Between Frontend and Backend Teams

When frontend and backend teams work in untyped JavaScript, API contracts exist only in Swagger documentation that is always slightly out of date. Frontend developers discover API changes at runtime, not compile time. Backend developers break API responses without knowing it. Integration testing catches these bugs late — after both teams have moved on to the next feature.

02
Our Solution

Shared TypeScript Types — API Contracts Enforced at Compile Time

We define shared TypeScript interfaces for all API request and response shapes — published as a shared types package consumed by both frontend and backend codebases. When the backend changes an API response, the TypeScript compiler immediately flags every frontend location that depends on it. Integration bugs surface at compile time across both codebases — before any code ships. The same typed contracts power the AI-powered features and mobile app API integration.

03
The Problem

TypeScript Project Configured Without Strict Mode — False Sense of Safety

Many TypeScript projects start with strict mode disabled — allowJs enabled, noImplicitAny off, strictNullChecks off. The project uses TypeScript syntax but lacks the compile-time guarantees that justify TypeScript's adoption. Null reference errors, implicit any propagation, and untyped third-party libraries create the same runtime bugs that TypeScript was adopted to prevent.

03
Our Solution

Strict TypeScript From Sprint One — Not a Target to Reach Later

We configure TypeScript strict mode from the first sprint — strictNullChecks, noImplicitAny, strictFunctionTypes, and useUnknownInCatchVariables all enabled. Type coverage is measured and reported as a metric on every sprint deliverable. When your TypeScript platform reaches production, it has genuine compile-time safety — not the appearance of it. The typed architecture scales cleanly to serve your mobile app development requirements without retrofitting types.

The AZRIVA Difference

Our Development Process

How We Deliver TypeScript Projects

A six-stage TypeScript development process — every sprint delivers a fully typed, zero-error build with a type coverage report. The same type-safe discipline whether building a TypeScript web platform or extending it to a <a href="/mobile-app-development-company-india" class="content-link">Flutter mobile app</a>.

01

Discovery & Type Architecture

We begin with a structured discovery call to understand your TypeScript project — application scope, existing JavaScript state if migrating, strict mode targets, and deployment architecture. We design the type system architecture — shared type packages, API contract interfaces, domain model types — before any TypeScript code is written.

02

Type Contract Design & UI Sign-Off

All API type contracts are documented — typed request interfaces, typed response shapes, typed error unions, typed configuration objects. For web applications, UI screens are designed and approved in Figma. No development begins until both type contracts and UI designs are signed off.

03

Fixed-Price Proposal

A fixed-price proposal covers the complete TypeScript scope — application architecture, type system design, API contracts, test coverage targets, build configuration, CI pipeline, and deployment. One price. Strict mode enabled by default. Zero TypeScript errors as a contractual deliverable.

04

TypeScript Strict Mode Development

Development runs in two-week sprints with strict TypeScript enabled from sprint one. Every sprint deliverable reports type coverage percentage. You receive a fully typed, staged build with zero compiler errors at the end of every sprint — type safety as a measurable, reported quality metric throughout.

05

QA — Type Coverage and Test Suite

Every TypeScript build passes strict compiler checks with zero errors, Jest unit tests with typed test utilities, integration tests against typed API contracts, and end-to-end tests with Playwright or Cypress. Type coverage report included in every sprint delivery. No build ships with compiler warnings suppressed.

06

Deployment & Mobile Extension

We manage TypeScript compilation to optimised JavaScript with source maps, type declaration files published for shared packages, and deployment to your chosen infrastructure. Post-launch support for 90 days. When your typed platform needs a mobile app — Flutter connects to your TypeScript API contracts as the integration foundation.

Who We Build For

TypeScript Architecture Built for Enterprise Scale

Every TypeScript project we build uses a domain-driven type architecture — shared type packages, typed API contracts, typed domain models, and typed configuration objects. Your TypeScript codebase is self-documenting. New engineers onboard in days. The type contracts your web platform defines become the precise specification for the Flutter mobile app when your users need it.

Zero runtime type errors

Compile-Time Safety — Zero Runtime Type Errors in Production

TypeScript strict mode catches null reference errors, undefined property access, and implicit any propagation before any code reaches production. Every sprint deliverable reports zero TypeScript compiler errors and a measured type coverage percentage. The categories of runtime bugs that cause production incidents in JavaScript codebases are structurally eliminated in strictly typed TypeScript.

03

Shared Type Contracts — API Bugs Caught at Compile Time

We define shared TypeScript interfaces for all API boundaries — published as typed packages consumed by frontend, backend, and mobile clients simultaneously. When the backend changes an API response shape, the TypeScript compiler flags every dependent consumer immediately — frontend, API layer, and mobile integration code. API contract bugs surface at compile time across all codebases before any code ships to production.

Type-Safe Security — Industry Best Practices and DPDP Compliance Built In

TypeScript strict mode prevents a class of security vulnerabilities that arise from untyped user input handling — implicit any types accepting unexpected payloads, null reference bypasses in authentication middleware, and untyped third-party library integrations. We combine strict TypeScript with runtime validation using Zod for all API boundaries. India DPDP Act compliance built into typed data handling architecture from day one.

05

Fixed Price. Every Project. No Exceptions.

The price in your proposal is the price on your final invoice. No hourly billing, no scope-creep additions, no change request charges for agreed features. Fixed price is not a marketing claim at AZRIVA — it is a contractual commitment on every Android engagement.

Your TypeScript Engineer on WhatsApp — From Day One

You communicate directly with the TypeScript engineers building your platform — on WhatsApp, Slack or video call. When a type contract needs updating or a migration sprint produces unexpected type errors, the engineer who designed the type architecture responds directly. No account managers. No ticketing systems. The person on your call at 9am IST is writing your TypeScript at 10am IST.

FAQ

TypeScript Development — Frequently Asked Questions

Our team has answered the most common questions about our services.

Updated May 2026
TypeScript development cost in India depends on project scope and complexity. A focused TypeScript web application or API platform starts from $6,000–$15,000. A mid-complexity TypeScript enterprise platform with full strict mode architecture ranges from $15,000–$40,000. Complex TypeScript platform engineering starts from $40,000 upward. JavaScript to TypeScript migration projects are priced based on codebase size and type coverage targets. As a full-service mobile app development company in India, we also build the Flutter mobile app on top of your TypeScript API. Contact us via our quote page for an estimate within 48 hours.
A focused TypeScript application takes 6–12 weeks. A mid-complexity TypeScript enterprise platform typically takes 14–24 weeks. Complex TypeScript platform engineering takes 24–40 weeks. JavaScript to TypeScript migration timelines depend on codebase size — a typical 50,000-line JavaScript codebase takes 12–20 weeks to migrate to strict TypeScript. We deliver a fully typed, tested staging build at the end of every two-week sprint with a type coverage report. After your TypeScript platform is live, extending to a Flutter mobile app using your typed API contracts typically adds 10–16 weeks.
TypeScript strict mode enables strictNullChecks, noImplicitAny, strictFunctionTypes, and useUnknownInCatchVariables — the flags that catch the most common categories of type errors. Without strict mode, TypeScript allows implicit any types and null references that still cause runtime errors. With strict mode, the compiler enforces complete type coverage. We enable strict mode from sprint one on every TypeScript project — not as a target to reach after development, but as a non-negotiable quality standard. Strict TypeScript is the only TypeScript that delivers genuine compile-time safety.
Migration is recommended when your codebase exceeds 10,000 lines and refactoring becomes risky, your team grows beyond two developers, runtime type errors are causing production incidents, or you are building a long-term platform multiple developers will maintain. TypeScript migration is incremental — TypeScript and JavaScript coexist during migration. We start with the most critical modules, add types progressively, and increase strict mode settings as coverage improves. When migration is complete, your typed API contracts are ready to power the mobile app your users need next.
Yes. JavaScript to TypeScript migration is a core TypeScript consulting service. We assess your existing JavaScript codebase, identify the highest-risk untyped modules, and create a migration plan that introduces TypeScript incrementally — your application stays live throughout. We start with allowJs enabled, type the most critical business logic first, configure strict mode progressively, and increase coverage sprint by sprint until the entire codebase reaches strict TypeScript compliance. Every sprint delivers a measurable type coverage improvement as a reported metric. Contact us via our quote page to discuss your migration.
Yes. Your TypeScript backend API is an excellent foundation for a Flutter iOS and Android mobile app. The typed API contracts your TypeScript backend defines — request interfaces, response types, error types — provide a precise specification for the Flutter mobile client to implement against. We build the Flutter mobile app using your TypeScript API types as the integration contract, reducing mobile API integration bugs to near zero. Your typed TypeScript backend serves both your web application and your mobile app from one deployment.
Yes. We build TypeScript AI service layers with fully typed interfaces for every AI API interaction — typed request payloads, typed streaming response handlers, typed error unions, and typed configuration objects. Our AI development team builds AI features that are as type-safe as the rest of your TypeScript application — not untyped API call wrappers that bypass your type system. The typed AI service layer serves both your web application and your Flutter mobile app from the same typed backend.
TypeScript development costs in India are 60–70% lower than equivalent agencies in the USA, UK, or Australia. Our mobile app development company in India works IST with 4-hour daily overlap with UK and 10+ hours with USA. Fixed price means the saving is locked in from day one. TypeScript's compile-time error catching also reduces the bug-fixing cost that inflates hourly-billed JavaScript projects — fewer production incidents means lower total cost beyond the initial development investment.
