Ask HN: Is it possible to compile TypeScript to Golang?

  >Typescript lets me write the complex logic What is it about Go that prevents you from writing this complex logic?
• crop_rotation 4y ago
  No, it is not (nor does it seem feasible). Why not just spin up multiple workers?
• thesuperbigfrog 4y ago
  It sounds like you need a language that supports stronger types and concurrency. There are many good programming languages that might work if neither Go nor Typescript individually would meet your needs. I recommend examining the following to see if they would work better for you: Ada: https://learn.adacore.com/courses/intro-to-ada/index.html https://learn.adacore.com/courses/intro-to-ada/index.html Elixir: https://elixir-lang.org/ https://elixir-lang.org/ Java: https://docs.oracle.com/javase/tutorial/ https://docs.oracle.com/javase/tutorial/ Rust: https://doc.rust-lang.org/book/ https://doc.rust-lang.org/book/ All of them have excellent support for concurrency and strong typing to various degrees that help you to write complex logic quickly.

    Elixir doesn‘t have support for static types built in.
    • giaour 4y ago
      It has support for type annotations, though, and tools like dialyzer can check for type errors much like TypeScript does: https://elixir-lang.org/getting-started/typespecs-and-behaviours.html https://elixir-lang.org/getting-started/typespecs-and-behavi...

    Interesting choices. Are there any languages which have concurrency semantics like Go?
    • mholyland 4y ago
      There are many languages with libraries that can use CSP (Communicating Sequential Processes)[0], but some popular languages that have it in the core libs are: Golang, Crystal and Clojure.

  Ts is dynamically typed unfortunately. And also this implies the whole js library to be made thread safe. But the good thing is A. Horizontal scalability is far better approach for most usecases anyway B. Nodejs is so performant youd rarely beat it with other GC languages in real applications.
  • ch_sm 4y ago
    > Ts is dynamically typed unfortunately What do you mean, specifically, with this statement? The point of TS is to give JS static types.
    • aristofun 4y ago
      That you can’t transpile dynamic language into a static one. If you call ts a statically typed language -> you dont know ts :)

  No, the Go threading runtime is fundamentally incompatible with JavaScript's event-loop model. TypeScript does not define runtime semantics, JavaScript does, and it's built to run in a single-threaded environment. You cannot use it to leverage Go's coroutines unfortunately.
  • karmakaze 4y ago
    You can get the semantics of coroutines and no parallelism by setting GOMAXPROCS=1, either via environment variable or set in the program initialization.

      It would remove the benefit of running on Go. It would be less efficient than v8 + libuv because your TypeScript on Golang runtime wouldn't be as fast as v8 + JIT to run the application code which is now written in a language built for dynamic dispatch.
  • alexbezhan 4y ago
    I don't need Javascript runtime semantics. I just want to use Typescript.

  This is not directly related to question but I would suggest using go just for those use cases. Programming in general has become a lot more abstract and standardised so with some exceptions (C/rust) you can easily use multiple languages without incurring much if any costs. Something else you can do thats slightly unorthodox is to write in typescript then ask chatGPT to rewrite your code in golang. You still have to maintain in golang but you get do the initial implementation part in typescript.
• Alifatisk 4y ago
  I don't think it's possible to run Ts in Golangs compiler. Have you considered rewriting your code to Go?
• patrickthebold 4y ago
  It would be helpful to know what specific problems you have with the single threaded model. You might still have some options staying with node. I think you can have worker threads but maybe you can't share memory, or you might be able to run multiple node processes. Otherwise you probably want to just switch to go.

  Write concurrent heavy tasks in Go. Write other tasks in typescript. Use https://connect.build https://connect.build to connect them.
