Unhandled 'error' event

[Horadrim]

Steps to reproduce:

1. Globally install srcbook with npm
2. Start the application
3. Click "Create Srcbook"
4. Upon writing a new title or pasting / writing any code, the application crashes.

Console output:

`

Hmm, I cannot seem to reproduce. I'm on mac, using chrome, deleted all my srcbook files (so, clean slate) and then ran:

npm i -g srcbook
srcbook start

This installed and booted [email protected].

I created a srcbook, entered a title, no crash. Then I tried writing code (without installing deps), no crash.

@Horadrim Hmm, me to, I am on Ubuntu, using brave, working fine, not able to reproduce this issue

I am getting the same error on Windows. I dug into it a bit and found its because of the difference in how windows handles the spawn call. it looks like it needs the option "shell" set to true for windows to be able to run tsserver:

 const child = spawn('npx', ['tsserver'], {
        cwd: options.cwd,
        shell: process.platform == 'win32',
 });

unfortunately it seems like there may still be other issues as am still unable to successfully run typescript cell code even after that change. But hopefully this gives you all a good starting point to supporting windows as well if you decide to do so :)

I forgot to mention that I'm using windows 11. I guess since the other guys can't reproduce it on Linux and Mac, seems to be a Windows only issue indeed.

@Cam-Bread Windows TS code is under the work it's just some extra work with windows white spacing in validators and a few places left not using path.join()
