Struggling to make coffeescript-to-typescript conversion work

I am currently in the process of converting a Coffeescript application to Typescript. I have come across a coffeescript-to-typescript tool that is supposed to simplify this task. However, I am facing difficulties getting it to work properly and the error messages seem quite absurd...

Here is an example of a Coffeescript file:

CoreModule.service('FileRequire', [
  # dependencies
  () ->
    @resolver = (subdirectory, extension) ->
      (pathcode) ->
        tmp = pathcode.split ':'
        modules = tmp[0]
        file = tmp[1]
        'app/modules/' + modules.split('/').join('/modules/') + '/' + subdirectory + '/' + file + '.' + extension

    return
])

When I attempt to execute it on my Windows machine with the globally installed typescript and coffeescript-to-typescript modules using the following command:

C:\development\mp-frontend>coffee-to-typescript -cma app\modules\core\services\FileRequire.coffee
error compiling app\modules\core\services\FileRequire.coffee
app\modules\core\services\FileRequire.coffee:4:6: error: unexpected TERMINATOR
    @resolver = (subdirectory, extension) ->
     ^
1 files failed

and

C:\development\mp-frontend>coffee-to-typescript -c app\modules\core\services\FileRequire.coffee
Error: spawn tsc ENOENT
    at exports._errnoException (util.js:746:11)
    at Process.ChildProcess._handle.onexit (child_process.js:1046:32)
    at child_process.js:1137:20
    at process._tickCallback (node.js:355:11)

Could someone please shed some light on what might be causing these issues? The TERMINATOR error appears to be a common problem with Coffeescript, even though the code compiles successfully with Grunt and functions perfectly fine (considering it ultimately transpiles to Javascript).

At this point, the tool seems rather ineffective... any guidance on where I might be going wrong would be greatly appreciated.

Answer №1

Upon encountering the identical error message, I found a solution that worked for me. The correct installation process for the tool is as follows:

sudo npm install -g typescript-to-coffeescript
sudo npm install -g tsc # This particular step resolved the issue for me.

I can confirm that this method was successful on my Ubuntu 20.04 system.

Answer №2

It appears that the tool is not yielding the desired results. Can someone kindly steer me in the right direction?

I suggest converting the coffeescript to JavaScript, and gradually incorporating TypeScript elements such as annotations and transitioning to ES6 functionalities like classes.
