What is Forst?
Forst is a programming language that compiles TypeScript-like backend code to Go, enabling developers to migrate from Node.js to Golang while maintaining type safety. It generates native TypeScript client definitions directly from source and supports incremental migration through Node.js interop.

Forst pros
- Compiles to Go with full access to Go ecosystem, standard library, and build tools for native performance
- Generates TypeScript definitions and client code directly from backend source—no intermediate schemas like GraphQL or Protobuf required
- Supports incremental migration—move parts of code at a time while existing systems keep running without full rewrites
- Allows calling existing Node.js libraries directly from Forst code during the migration process
Forst cons
- Actively developed with experimental features—not yet production-stable
- Requires learning a new language syntax; smaller ecosystem compared to established Go and TypeScript communities
- Limited to backend-to-Go migration use case; not a general-purpose language replacement
Frequently asked questions about Forst
Can I migrate gradually or do I need to rewrite my entire backend?
Forst supports incremental migration—you can move small parts of your code at a time while your existing codebase keeps running, so you don't need a full rewrite.
Do I need GraphQL or Protobuf for type safety with clients?
No. Forst generates native TypeScript definitions and client code directly from your backend source, eliminating the need for intermediate languages.
Can I still use my existing Node.js libraries during migration?
Yes. Forst supports calling existing Node.js code directly, allowing you to keep using existing tools and libraries while migrating.
