Medium to high CPU Usage when atom-typescript is enabled

[chris69]

My 2013 Macbook with OS El Captain runs an AtomHelper process with 10-30% CPU usage, when atom-typescript is enabled in preferences. I have an typescript project open. The laptop becomes hot and the ventilators are running constantly. I had to disable the plugin at the end.

Can you please fix this? Thank you.

Tested with atom version 1.9.7 and 1.9.8 and atom-typescript version 10.1.6 (newest to date).

System:

Model Name: MacBook Pro
Model Identifier: MacBookPro10,1
Processor Name: Intel Core i7
Processor Speed: 2.7 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 16 GB

Same issue here. Atom v1.9.9 and atom-typescript v10.1.6

I managed to increase performance significantly by modifying the file tsconfig.json to this:

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": false,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false
    },
    "exclude": [
        "node_modules",
        "platforms"
    ]
}

The compilerOptions has no performance impact for me and

  "exclude": [
        "node_modules",
        "platforms"
    ]

does not really helps.

After opening one or more ts files Atom (atom-typescript) still starts to use 18%-30% of my CPU on my iMac (3.5 GHz Intel Core i5) for minutes, even if I change the focus to another application. After some time the cpu usage slows down, but when I just click in the atom editor without doing anything it starts again.

Same, very slow and high CPU usage, macbook pro.

Same issue, on Windows 10. Very high CPU usage and typing in editor lags.

Switching to atom-typescript-beta solved this problem for me.
See #1166

I think this issue can closed after atom-typescript-beta is merged into the master branch

Yep, should be fixed now!
