No definition found when ts code is in a subfolder

[AndrewSav]

Hi there!
So I tried to installing atom and atom-typescript to see how it compares with Visual Studio / WebStorm for nodejs web projects. What I immediately noticed is that I'm getting Atom Ts: No definition found.

"What the heck does this mean?" though I. Well after searching the issues here, it became apparent that this is because of missing tsconfig.json. (Could the error message be improved? A user has no fighting chance dealing with this cryptic error message).

But the thing is, my tsconfig.json was not missing. It was there all right. It was working perfectly in WebStorm. What I quickly realized is that atom-typescript expects tsconfig.json at the project root.

I prefer to have all typescript files in a subfolder (as opposed to js, etc). Firstly I feel it's cleaner. Secondly, from time to time ts files appear inside node_modules, and ts compiler (at least in webstorm) dutifully walks the whole tree and compile them. And then complains. I did not want that to happen so I moved all my TS in a subfolder, put there tsconfig.json and it worked perfectly, but not in atom.

How do I configure atom-typescript so that it looks for tsconfig.json in a different place and starts transpiling from that folder? Is it possible to improve the error message?

Atom Ts: No definition found

That is for if you pres f12 aka goto definition. The message seems right for that.

Not true.

It looks at all folder above the current open .ts file. This is the way tsc is designed to work as well 🌹

Feel free to discuss any other issues here, we'd be hapy to help 🌹

Thank you for this. It must have been artifact from very old Atom installation. I removed it completely and reinstalled from scratch, after that all started working as expected.

I'm also getting this error 'No Definition Found'. It seems to compile the *.ts files fine until I add the 'out' options to the tsconfig.json then it stops compiling the ts files on save. If I press F12 from within a ts file I then get the 'No Definition Found' error.

Here is a simplified version of the project:

root
  models
    modelOne.ts
    modelTwo.ts
 module.name.ts
 tsconfig.json

Sorry for wasting your time it is working now adding the 'buildOnSave' options then uninstalling and reinstalling atom it is working as expected. Seems odd I had to uninstall though?

You are not on windows are you? #195

Yeah, that looks like the issue

I was getting the same problem, but all I did was set "buildOnSave" from false to true, and restart the atom IDE. It was working fine with me without reinstalling.
