GoScript - Go to TypeScript Compiler

Go to TypeScript compiler

GoScript compiles Go to TypeScript at the AST level. Share algorithms and business logic between your Go backend and TypeScript frontend.

Playground Source

goscript-demo

                  Input
                  main.go
                

                  package main

type Counter struct {
    value int
}

func (c *Counter) Increment() {
    c.value++
}

func main() {
    c := &Counter{}
    c.Increment()
    println("Count:", c.value)
}
                

                  Output
                  main.ts
                

                  import * as $ from "@goscript/builtin"

export class Counter {
  public value: number = 0

  public Increment(): void {
    this.value++
  }
}

const c = new Counter()
c.Increment()
$.println("Count:", c.value)
                

Status

🎯

Goal

Share algorithms and business logic between Go and TypeScript without maintaining separate implementations.

✅

What works

Structs, interfaces, methods, generics, channels, goroutines, pointers, slices, maps, closures, control flow, reflection, encoding/json, and most of the standard library.

🧪

Tests

Verified by a compliance suite that compiles Go code and executes the generated TypeScript.

🚧

In progress

Reflection edge cases, full standard library coverage.

⚠️

Limitations

Uses JS number (64-bit float). No unsafe, uintptr, or complex numbers.
