Question 1

How much do TypeScript development services cost?

Accepted Answer

TypeScript projects range from $15,000 for incremental migration and tooling setup to $90,000+ for full-stack rewrites with strict typing across frontend and backend. Cost depends on codebase size, legacy JavaScript complexity, and API surface area. Discovery audits produce a phased migration plan with clear milestones.

Question 2

How long does a TypeScript migration take?

Accepted Answer

Small codebases can adopt TypeScript in 2–4 weeks; large React or Node.js apps typically migrate over 8–16 weeks in incremental PRs. We enable strict mode gradually with `allowJs` and path-by-path conversion to avoid blocking releases. Parallel feature development continues throughout migration.

Question 3

Why choose TypeScript over plain JavaScript?

Accepted Answer

TypeScript catches bugs at compile time, improves IDE autocomplete, and makes refactoring safer as teams and codebases grow. Shared types between frontend and backend eliminate contract drift. Enterprise and SaaS teams rely on TypeScript for long-term maintainability and faster code reviews.

Question 4

Can you migrate our existing JavaScript project to TypeScript?

Accepted Answer

Yes. We migrate React, Next.js, Node.js, and Express codebases using incremental adoption—converting modules file by file while keeping CI green. Type definitions for third-party libraries are added or authored where `@types` packages are missing. Strict compiler options are tightened over time.

Question 5

What TypeScript stack do you use?

Accepted Answer

We use TypeScript 5+ with strict mode, ESLint typescript-eslint rules, and Prettier for formatting. Frontends pair with React or Next.js; backends use Node.js with Express, Fastify, or NestJS. tRPC or OpenAPI-generated types keep API contracts synchronized across layers.

Question 6

How do you ensure TypeScript code quality at scale?

Accepted Answer

CI pipelines run `tsc --noEmit`, linting, and unit tests on every PR. Shared internal packages publish typed utilities and domain models. Code review checklists enforce proper generics, discriminated unions, and avoidance of `any` except at integration boundaries.

Question 7

Can TypeScript work with our existing backend?

Accepted Answer

TypeScript frontends consume any REST or GraphQL API; we generate types from OpenAPI specs or GraphQL schemas. Node.js backends can be migrated to TypeScript while other services remain in Python or Laravel. BFF layers in TypeScript unify multiple backend contracts for the UI.

Question 8

Do you provide ongoing TypeScript maintenance?

Accepted Answer

We handle TypeScript version upgrades, dependency updates, and type-error remediation after major framework releases. Refactoring services improve type coverage and remove technical debt from early migrations. Documentation and ADRs help your team sustain strict typing practices.

Question 9

Can TypeScript developers join our existing team?

Accepted Answer

Our engineers embed in your repos, standups, and PR workflow using your conventions and monorepo tooling. We can lead typing strategy or augment capacity on critical modules. Knowledge transfer sessions cover patterns for generics, utility types, and API typing.

Question 10

When should I hire dedicated TypeScript developers?

Accepted Answer

Hire TypeScript specialists when your product has outgrown untyped JavaScript, multiple teams share APIs, or compliance requires auditable code quality. It is essential for large React/Next.js apps and Node.js microservices where runtime errors are costly. Choose TypeScript when maintainability and velocity matter more than initial setup speed.
