Wondering what is the position now. Its been more than a year and // NOSONAR is not working on (Typescript) project.
I moved your message to a new thread since it has IMO no relations with quick fixes. I just give a quick try, and
// NOSONAR is working fine in TypeScript files.
Please share a bit more details so that we could help you: what is your IDE? What is the version of SonarLint? Are you using connected mode?
