Issue Type: Performance Issue

Upon opening VS Code, JS/TS Features are initialized. This causes the Application to grind to a halt. I am not even using Typescript and I'm still forced to wait for this.

VS Code version: Code 1.43.1 (fe22a9645b44368865c0ba92e2fb881ff1afce94, 2020-03-18T07:17:38.324Z)

What exactly doesn't work while you see the progress indicator? It only indicates that the typescript server that powers both JavaScript and TypeScript language features is initializing (it is run its own process so it doesn't block VS Code)

[klleroy]

Well I can tell you that it is blocking VS Code from running. I can't do anything while that is running. Oftentimes it takes about 3-5 minutes to complete. Sometimes less, sometimes more.

[mjbvz]

But what does "can't do anything mean"? Does it not respond to any input? Can you share a video of this?

[mjbvz]

Also does this reproduce with all extensions disabled?

[klleroy]

Ahh. Seems I may have spoken prematurely. Seems to not block actual functionality (browsing to various site files, etc). But won’t allow you to install any node packages until VS Code has completed the task in question. Is that expected? Haven’t had a chance to disable all extensions.

[mjbvz]

No, it should not block that. How are you installing the node packages?

[klleroy]

I use NPM so... npm i <package name>

[mjbvz]

Do you see an error during the install? Please also test with extensions disabled to make sure one of them isn't causing this

[klleroy]

Negative. No error seen. App just hangs while that task runs/completes.

My Repro Steps

• Open VS Code
• JS/TS Features are initialized
• Install a node package in a project via npm i abcPackage
• App hangs until JS/TS Features task is complete

I'll try and test with extensions disabled and report back.

[mjbvz]

Did you see this after disabling extensions?

[klleroy]

Sorry it's taken me so long. I've just confirmed that still experience the same symptoms even after disabling all extensions.

[mjbvz]

Can you please collect the TS Server log from when this happens:

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 large log file called tsserver.log

If you can share the log, I can take a look to see if anything stands out that would explain this

⚠️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

[klleroy]

Hi Matt -
Here's the latest results.
tsserver.log

[mjbvz]

@jobu206 Was this log was collected during the hang?

Potentially sounds similar to #37653 but the logs don't show an install

[klleroy]

@mjbvz yep, sure was.

[sheetalkamat]

@klleroy please check if this is still the issue, if it is, provide the log using latest vscode and typescript nightly.
I would want you to follow the repro steps completely ( do let us know those steps) and wait for log to complete for those requests before you submit the log. Your previous log just shows project initializing but doesnt show npm install or anything else which is where you are seeing the issue.

You can upload logs by following these steps:

1. Set "typescript.tsserver.log": "verbose"
2. Restart vscode or vscode insiders
3. Reproduce the problem
4. In vscode or vscode insiders, run the TypeScript: Open TS Server log command
5. This should open a large file called tsserver.log. Please share this file. Additionally you can also share file ti.log created next to it.

[klleroy]

I've been attempting to test this out but I can't get a repro. Closing as no repro. Will open a new issue if I have more problems.
