TSLint in Visual Studio 2015/2017? - visual-studio

Question

My organization uses TSLint pretty heavily for quality-checking our Typescript code, and it provides a valuable service to us! However, we use Visual Studio 2015 & 2017 as our main IDE and the only way to get the linting results it to run a gulp/grunt task which prints the output to the Task Runner Explorer console. It works, but it's slow and not the best development experience.
In smaller projects on my own I've used VSCode, which has a fantastic TSLint plugin that highlights linting violations as you make them, and provides access to the auto-fixers that some TSLint rules have. Like this:
Is it possible to get this same functionality in Visual Studio 2015/2017? The immediate feedback is a life saver when writing TypeScript code.

Answer 1

As #Hermann Gruber has mentioned, in Visual Studio 2015 Mads Kristensen's Web Analyzer extension provides support for TSLint of the kind you require.
For Visual Studio 2017 and 2019 I have now personally upgraded Mads' extension, and rebranded it as 'TypeScript Analyzer' as it only supports TSLint. It's available in Visual Studio's Extensions and Updates Gallery under 'TypeScript Analyzer'.

Answer 2

This is something I coded in a day or two (note that I haven't worked with C# for a few years):
https://github.com/vladeck/TSLint
It is a start of (hopefully) worth-wile Visual Studio 2017 extension that can mark .ts code withing the editor, based on the installed tslint and tslint.json configuration.
It is not published on the marketplace yet (a lot more coding to do), but you can download and build it yourself. Give it a try, If you have the time. The more people try it out, the more I will have data needed to make it worth-wile.

Answer 3

This is reported as an issue in the Visual Studio Developer Community.
https://developercommunity.visualstudio.com/content/problem/22907/please-support-tslint-as-how-its-supported-in-vs-c.html
The status is "triaged", so I assume that a comparable feature is not (yet) available. You may want to upvote the issue, so that it gets more attention by the VS development team.
EDIT: As noted in the following question, the visual studio plugin web analyzer provides support for tslint in VS 2015 (but not VS 2017):
Set up TSLint for VS2017

Looks like if you are using typescript 3.0 or higher you just need to add tslint plugin into your tsconfig file. Install typescript-tslint-plugin below and you may need to restart visual studio (or simply close all your files and re-open them)
https://github.com/Microsoft/typescript-tslint-plugin
First
npm install --save-dev typescript-tslint-plugin
Then
{
"compilerOptions": {
"plugins": [
{
"name": "typescript-tslint-plugin"
}
]
}
}
