Versions.

Repro steps.

The log given by the failure.

Desired functionality.

Mention any other details that might be useful.

Like #5497 please add TSLint Language Service plugin.

And give an option to declare it in the tsconfig.json like this:

{
  "compilerOptions": {
    "plugins": [
      { "name": "tslint-language-service"}
    ]
  }
}

This TypeScript plugin can be used with any IDE (VSCode, WebStorm, Eclipse, etc) to provide tslint diagnostic and codefix in your editor.

Thanks!

Oh sorry, this wasn't fixed by #6144.

I'm marking this as a discussion though, adding it depends on up to date versions of a lot of things so it's not a cut and dry thing.

As far as I know, it depends on [email protected]. And @angular/[email protected] also depends on this typescript version.

I installed package, add lines in tsconfig and disable tslint extension in my vscode.
All seems to be working properly.

[ValeryVS]

With tslint-language-service it is possible to view errors for rules, that require type checking.
But not all...
For example, I can't see no-unused-variable errors in VSCode.

Rules, that require type checking, aren't work with current vscode-tslint plugin any way.

[angelozerr]

@ValeryVS the goal of this issue is to integrate tslint-language-service with angular-cli.

For example, I can't see no-unused-variable errors in VSCode.

For now tslint without the language service has been sufficient for the CLI. Let's close this feature request for now and revisit in future.
