Performance : TypeScript 2.3 language service proxy

[cyrilletuzi]

Bug Report

• TSLint version: last
• TypeScript version: 2.3
• Running TSLint via: VSCode

Actual behavior

tslint uses its own TypeScript process, impacting performance.

Expected behavior

With TypeScript 2.3 language service proxy, already shipped in nightlys, tslint can use the main TypeScript process, with just this line in tsconfig.json :

{
  "compilerOptions": {
    "plugins": [{ "name": "tslint" }]
  }
}

There are already :

• a try : https://github.com/angelozerr/tslint-language-service
• instructions to do TypeScript plugins : https://github.com/RyanCavanaugh/sample-ts-plugin
• a working example : @angular/language-service

Isn't angelozerr/tslint-language-service already doing this? The only thing I noticed that it doesn't do is outputting anything (along with compiler errors) when tsc runs, but I'm not sure if it's possible with these language service plugins.

Closing, as a new VS Code extension is coming for this.
