TypeScript engineering for codebases that stay safe to change
Codersarts builds and maintains TypeScript applications across the front end and back end, from React and Angular interfaces to Node.js APIs and shared libraries. Our engineers set up strict typing, migrate JavaScript codebases to TypeScript step by step, design typed APIs and data models, and clean up type errors, so your team can refactor and ship with confidence instead of fear.
What Is TypeScript Development?
TypeScript development is the building of software in TypeScript, a typed superset of JavaScript from Microsoft that compiles to plain JavaScript. It covers typed front ends and back ends, compiler configuration, migration from JavaScript, shared types between client and server, runtime validation, type-safe API clients, monorepos, testing and build tooling.
TypeScript catches many bugs before code runs and makes large codebases easier to navigate. Its value depends on how it is used: loose settings and widespread `any` types give little protection.
TypeScript Development at a Glance
Item | Detail |
|---|---|
What we build | Web apps, APIs, SDKs, shared libraries, monorepos and serverless functions |
Front ends | |
Back ends | Node.js, NestJS, Express and tRPC |
Migration | JavaScript to TypeScript and loose to strict settings |
Engagement | Fixed-scope project, migration project, dedicated TypeScript developer or ongoing support |
What we can do with TypeScript
Service | What it covers |
|---|---|
TypeScript application development | Full-stack products in one typed language |
JavaScript to TypeScript migration | File-by-file conversion without stopping delivery |
Strict mode adoption | Removing `any` and enabling strict checks |
Typed API design | Shared types, OpenAPI and tRPC contracts |
Runtime validation | Zod schemas that match compile-time types |
SDK and library development | Typed packages for internal or public use |
Monorepo setup | Shared types and tooling across apps |
Build and tooling | Faster builds, linting and CI checks |

TypeScript technology ecosystem
From TypeScript requirement to production
Assess. Review code, current typing and pain points.
Plan. Define target settings and migration order.
Configure. Set up compiler, linting and CI checks.
Build or migrate. Convert or develop in small increments.
Tighten. Enable stricter checks as coverage grows.
Maintain. Keep types, tools and dependencies current.
TypeScript in production: what we take care of
Strict compiler settings rather than permissive defaults.
No silent `any` through lint rules and reviews.
Runtime validation at API and form boundaries.
Generated types from OpenAPI, GraphQL or database schemas.
Type checks in CI so errors never reach main.
Incremental migration that keeps releases flowing.

Frequently Asked Questions
What TypeScript services does Codersarts provide?
We provide TypeScript application development, JavaScript migration, strict mode adoption, typed API design, runtime validation, SDK development, monorepo setup and tooling.
Can you migrate our JavaScript app to TypeScript?
Yes. We convert file by file, starting with shared code, so releases continue during the migration.
Is TypeScript worth it for a small team?
Usually yes. Types catch common bugs early and make code easier to change as the product grows.
Can you share types between our front end and back end?
Yes. We use shared packages, tRPC or generated types from OpenAPI or GraphQL schemas.
Do types replace tests?
No. Types catch structural errors; tests check behavior. We use both.
Can you fix thousands of type errors after enabling strict mode?
Yes. We tighten settings gradually and fix errors in prioritized batches.
Do you build TypeScript SDKs?
Yes. We build typed, documented SDKs for your API and publish them to npm.
Do we own the code?
Yes. All code and documentation are yours.
