VSCode not recognizing tslint-language-service

I’m not sure if I’ve configured something incorrectly or if vscode is just struggling but I can’t manage to get vscode to lint properly through the tslint-language-service.

tsconfig.json

{
  "compilerOptions": {
    "outDir": "./dist/",
    "sourceMap": true,
    "noImplicitAny": true,
    "allowSyntheticDefaultImports": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "module": "commonjs",
    "types": ["mocha"],
    "target": "es2015",
    "jsx": "preserve",
    "experimentalDecorators": true,
    "plugins": [
      { "name": "tslint-language-service" }
    ]
  },
  "files": [
      "./src/abstractions/index.d.ts",
      "./node_modules/@types/webpack-env/index.d.ts",
      "./src/index.tsx"
  ],
  "exclude": [
      "node_modules"
  ],
  "include": [
    "."
  ]
}

tslint.json

{
	"rules": {
		"no-unused-expression": true,
		"no-duplicate-variable": true,
		"no-duplicate-key": true,
		"no-unnecessary-qualifier": true,
		"class-name": true,
		"interface-name": [true, "always-prefix"],
		"no-unnecessary-callback-wrapper": true,
		"object-literal-key-quotes": [true, "as-needed"],
		"object-literal-shorthand": true,
		"quotemark": [true, "single"],
		"semicolon": [true, "always"],
		"arrow-parens": [true, "ban-single-arg-parens"],
		"prefer-const": [true, {"destructuring": "any"}],
		"prefer-method-signature": true,
		"indent": [true, "spaces"],
		"use-isnan": true,
		"switch-default": true,
		"restrict-plus-operands": true,
		"radix": true,
		"no-var-keyword": true,
		"no-use-before-declare": true,
		"no-empty": true,
		"no-duplicate-super": true,
		"no-debugger": true,
		"no-default-export": true,
		"no-construct": true,
		"no-conditional-assignment": true,
		"no-string-throw": true,
		"promise-function-async": true,
		"prefer-for-of": true,
		"adjacent-overload-signatures": true,
		"typeof-compare": true,
		"triple-equals": [true, "allow-null-check"]
	}
}

server.ts (file I’m intentionally trying to break to catch errors)

var x = 2;

export function CreateThings(id){
  x = '2'; 
  var y = 2;  
  console.log("hello"); 
  console.log('hello');  
}

This should trip on multiple levels: no vars, single quotes, etc. Running TypeScript 2.3.3 Note: I can run tslint via the command line and it picks up on errors as expected.

@victornoel I suggest you also try the vscode-tslint(vnext) extension. It bundles the tslint-language-service https://marketplace.visualstudio.com/items?itemName=eg2.ts-tslint

@jnarwold have you also forced the use of the project’s typescript install in vscode (by clicking on the version of typescript on the bottom right of the screen, next to the smiley and then selecting “use workspace version”).

@angelozerr I’ve noticed that if you don’t set "typescript.tsdk": "./node_modules/typescript/lib" in the workspace settings of vscode, it does not propose to use it…
