ESLint Violations as Warnings in VS Code

If you're using TypeScript and ESLint in VS Code, wip files or legacy files can quickly explode into a sea of red squiggles, making it hard to know where to start or track what's going on.

I like to hone in on type errors first, since they're typically more critical (as in, type errors will often completely crash your code). I keep those as scary red squiggles and tone ESLint down a bit by changing all its squiggles to just (orange) warnings.

This is easy to do with a quick edit to your user settings JSON file (accessed via the >Preferences: Open User Settings (JSON) command in VS Code):

"eslint.rules.customizations": [
{ "rule": "*", "severity": "warn" },
]

Use @link JSDoc comments

Use {@link VarName} in JSDoc comments when referencing variables or types to get:

  • "Rename Symbol" support in VS Code
  • "Go to Definition" support in VS Code
  • "Find All References" support in VS Code
  • generated doc links to the original reference (in packages like typedoc)

I assume that all the features in VS Code are driven by the TypeScript Language Server and thus are applicable to any editor that utilizes that same language server.
