What TypeScript version are you using in your workspace? Does it this still happen if you use TypeScript 3.5.1?

[scrossan-crown]

Yes I am currently using 3.5.1.

[scrossan-crown]

The project I mainly work, the files are located on a remote server. When i created a copy locally it still displayed the above issue but after about 5 minutes it successfully initialized with full intellisense.

[mjbvz]

How are you loading the files from the remote server? A network drive? Some other approach?

[scrossan-crown]

Via a network drive Z:

[scrossan-crown]

I've left the intellisense running this morning when I got in today and it took about 30 minutes to fully initialize but it did and is now fully functional. Another issue I'm having (could be related to this issue) is that when I create a new file to it takes a long time to get any import intellisense, which slows down my development quite a bit.

[mjbvz]

Is this a regression or has it always been this way? Also, can you try temporary removing any tsconfig.json files that you have so that we do not try reading in the entire workspace to provide intellisense. This could be slow on a network drive.

I also see you are opening a root folder on the Z: network drive in VS Code. About how many files does this contain? You can run code --status from the command line to get a rough idea of this

[scrossan-crown]

The workspace I'm using is at z:\tenogo and the typscript project is located at z:\tenogo\web

output of code --status run at z:\tenogo\web

output of code --status run at z:\

Removing the tsconfig.json did allow it to initialize a lot faster.

[RyanCavanaugh]

Impossible to say what's going on without a concrete repro

[mjbvz]

@RyanCavanaugh To provide full project intellisense, won't TS Server try to index the entire project? On a network drive, that could be very slow. I don't know if there's anything we can do to fix this unless we see that TS Server is being too eager in its indexing or something like that.

@scrossan-crown Can you check your TS Server log to see if the server is picking up unexpected files or indexing too much:

1. Set "typescript.tsserver.log": "verbose",
2. Restart VS Code and reproduce the problem
3. In VS Code, run the TypeScript: Open TS Server log command
4. This should open a file called tsserver.log file in it

Look through that log file for lists of project such as:

...

If you can share the log, we can also take a look to see if anything stands out

⚠️Warning: The TypeScript log may include information from your workspace, including file paths and source code. If you have any concerns about posting this publicly on Github, just let me know and we can arrange something else. On our side, we only use these logs to investigate issues like this

[scrossan-crown]

@mjbvz is it possible for me to send you this log somewhere other than github?

Also It's only in the last couple of months that it's been this slow, before that it only took a minute or two to initialize. I'm happy to wait for the initial initialization but the biggest issue I face is when creating a new ts or tsx file it can take a long time for intellisense to be available in that file. I'm not sure it needs to re-index the whole project or why it's happening, but that slows things down a lot.
