@kai23 thank you for opening this issue. I have observed similar behavior and think it could be related to Microsofty/TypeScript #10735 .

I cannot reproduce right now

Can you help me track this down?

Add this to your settings

"typescript.tsserver.trace": "verbose"

Additionally, set the environment variable TSS_LOG=-level verbose. there should be a log file written next to tsserver.js that would have the form of .log[0-9]+

Here is the full log. I did the exact same thing as shown in the gif : http://pastebin.com/pr32P8j8

maybe that's the part which you may like ?

[Trace - 9:12:34 PM] Sending request: completions (3). Response expected: yes. Current queue length: 0
Arguments: {
    "file": "/Users/XXXX/Hello/app.js",
    "line": 1,
    "offset": 2
}
[Trace - 9:12:34 PM] Response received: completions (3). Request took 3 ms. Success: false . Message: Error processing request. No Project.
[Error - 9:12:34 PM] 'completions' request failed with error.
Error processing request. No Project.

and :

[Trace - 9:12:34 PM] Response received: projectInfo (4). Request took 2 ms. Success: false . Message: Error processing request. Cannot read property 'projectFilename' of undefined

Edit: Because I needed to work today, I installed the project manager extension. I removed it, but still.
Edit 2: have seen this issue ( microsoft/TypeScript#8212 ) but don't understand how it was fixed
Edit 3: adding a jsconfig.json file juste makes things worst, no autocomplete at all ( with this :

{
    "compilerOptions": {
        "target": "ES6"
    },
    "exclude": [
        "node_modules"
    ]
}

Edit 4 : same things happen in the insiders build

PS : didn't found the log file. Maybe I'm not searching the right place ?
