What We Build
What We Build With TypeScript Development
Production applications across product types — scoped to your users, stack, and growth stage.
6 product types — compare what we ship with TypeScript in production.
- Platform
JavaScript to TypeScript Migration
Incremental migration of existing JavaScript React, Node.js, or Vue codebases to TypeScript without pausing feature development or rewriting from scratch.
- SaaS
Type-Safe API Layer
End-to-end type safety using tRPC, GraphQL Code Generator, or OpenAPI TypeScript generator ensuring frontend/backend contract alignment as schemas evolve.
- Commerce
Enterprise Application Development
Large TypeScript applications with strict mode, discriminated unions, and branded types for complex domain modelling.
- Internal
Monorepo TypeScript Setup
Nx or Turborepo TypeScript monorepos with shared type packages, path aliases, and project references for multi-app codebases.
- Design
TypeScript Library Development
Building published TypeScript libraries with proper declaration files, ESM/CJS dual output, and public API design.
WHY CODEFLAMME
Not Another Offshore Vendor
We know the hesitation. Here's exactly how we're different.
You Talk to the People Building It
No account managers relaying messages. You're in direct contact with the founder and senior engineers on your project — every sprint, every decision.
No Bench Rotation
The team that scopes your project is the team that ships it. We don't swap engineers mid-project to free them up for someone else.
NDA Before We Talk Details
Your idea and IP are protected from the first real conversation — not after contracts are signed.
Full IP, Zero Strings
Every line of code, every design file, transfers to you on delivery. No licensing, no retained rights, no surprises.
Our Capabilities
Our TypeScript Development Services
Core delivery areas for TypeScript — architecture, implementation, and production hardening.
- 01
TypeScript Configuration
tsconfig.json design for strict mode, incremental compilation, project references, and path alias configuration.
- 02
Advanced Type Patterns
Utility types, conditional types, mapped types, template literal types, and discriminated unions for complex domain modelling.
- 03
End-to-End Type Safety
tRPC, zod validation, and OpenAPI TypeScript generation for type-safe data flow from database to UI.
- 04
Strict Migration Strategy
Incremental JavaScript to TypeScript migration — starting with allowJs, adding types file by file, without blocking feature development.
- 05
Runtime Validation
Zod, Valibot, or Yup schema validation integrated with TypeScript types for safe data parsing at API boundaries.
- 06
Tooling Setup
ESLint with typescript-eslint, Prettier, Husky, and lint-staged for consistent TypeScript code quality enforcement.
When to Choose
When TypeScript Development Is the Right Choice
Decision scenarios where TypeScript is the strongest fit — and why it earns the recommendation.
SCENARIO 01
Primary use case
You have a growing engineering team
TypeScript prevents an entire class of bugs that become increasingly costly as team size grows. The ROI on TypeScript increases with team size.
02
Scenario
You are building a long-lived application
Applications maintained over years benefit significantly from TypeScript's documentation-by-type and refactoring safety — especially when original authors rotate off the team.
03
Scenario
You use API contracts between services
TypeScript end-to-end type safety eliminates the most common source of bugs in microservice and frontend/backend integration when contracts change frequently.
04
Scenario
You are adopting monorepo architecture
TypeScript project references and shared type packages are fundamental to efficient monorepo development across web, API, and shared libraries.
In Practice
How We Use TypeScript on Real Builds
Where TypeScript shows up in our delivery work — product codebases, migration paths, and how it ties to React and Node.
TypeScript is the default for new React, Next.js, and Node work we ship: SaaS frontends, Nest or Express APIs, shared domain packages in monorepos, and typed clients from OpenAPI. Migrations stay incremental — allowJs first, then file-by-file strictness — so product work continues. Zod sits at API boundaries so runtime data matches UI types.
We adopt TypeScript when a codebase will outlive a single developer. Plain JavaScript remains fine for throwaway scripts. On product work it pairs with React for UI, Node/Nest for APIs, and web delivery that treats shared types as architecture, not an afterthought.
Concrete patterns include a packages/types workspace consumed by web and mobile clients, DTO-first Nest modules, and gradual strictness flags so legacy folders do not block new features. We keep compiler and ESLint rules aligned across apps so CI catches drift before merge rather than at runtime. Path aliases and project references keep monorepo builds honest about which packages may import which.
- 01
React
Typed props, hooks, and API response models are how we keep large React surfaces refactorable as features and teams grow.
- 02
Node.js
Node backends we build are TypeScript-first — services, workers, and shared packages use the same type system as the web client when stacks align.
- 03
Web Development
TypeScript is a delivery default across our web engagements, from design-system components through API contracts and CI type checks.
