Resolving modules and Intellisense Autocompletion in our Project takes a long time...

Maybe this problem is a result of using absolute paths.
Here is our jsconfig.json of the project:

{
  "compilerOptions": {
    "target": "es6",
    "module": "es6",
    "baseUrl": "./",  // all paths are relative to the baseUrl
    "paths": {
      "~/*" : ["*"]   // resolve any `~/foo/bar` to `<baseUrl>/foo/bar`
    }
  },
  "exclude": [
    "api",
    "build",
    "node_modules",
    "public",
    "seeds",
    "sql_updates",
    "tests.build"
  ]
}

Can i somehow debug which directories VSCode is resolving to find my correct file.
And is there maybe a way to cache this resolved pathy specific for this IDE on my Client... to make the IDE not search my Filesystem every time - or do you plan on make this in the future

Maybe it is, because our Project has about 550 Files in 120 Folders?

(excluding all folders mentioned above)

We have a similar problem as well. We have ~900 folders with ~3900 files.

Here is the tsconfig.json we are using:

{
    "compilerOptions": {
        "allowJs": true,
        "baseUrl": "./src",
        "jsx": "react",
        "module": "commonjs",
        "noImplicitAny": true,
        "outDir": "./dist/",
        "sourceMap": true,
        "strictNullChecks": true,
        "target": "es5"
    },
    "include": [
        "src/**/*.js",
        "src/**/*.jsx",
        "src/**/*.ts",
        "src/**/*.tsx",
        "typings/*.d.ts"
    ],
    "exclude": [
        "node_modules"
    ]
}

I often see "Loading..." while module path is being resolved. Even when path is resolved (displayed as tooltip/quickinfo), cmd + click takes a good 2 to 10 seconds to open the file. Happy to share more info if I know how to debug this.

To investigate what is causing this slowdown, please try collecting the typescript server log:

1. Set "typescript.tsserver.log": "verbose"
2. Restart VSCode with the --disable-extensions command line flag to disable all extensions.
3. Reproduce the issue
4. Run the Open TSServer log File command and view the tsserver.log file

Each request to the tsserver should have timing information. Look for the quickInfo requests and responses towards the end of the logs. If you can share the log file I can take a look through them 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

[ChiefORZ]

Thanks for the response!

Made the server log executing only the issued problem. The quickInfo request does really need 11 seconds to execute...

here is my logfile. thanks for taking time for it :)

Thanks @mjbvz. Attached are verbose logs for Today's insider version (f977399). Grepping for "elapsed", I see logs ranging from 1ms to 18s.

Let me know if there is anything else I can do to provide more info.

I'm getting a similar effect with only 2 files in the project, one of which is a module that exports a big array, and the second file imports this module. At first after Code starts everything is fine, but then autocompletion becomes increasingly slow. This project and the logs can be found here. Might be a good isolated illustration of the issue.

vscode: 1.13.0-insider f977399
ts 2.3.4

I was trying to debug typescript server over the weekend but oss version didn't load builtin extensions nor let me install chrome debugger to debug typescript server. Is there an argument I need to pass in to enable extensions in dev?
