✅ Viability Checklist

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types
• This feature would agree with the rest of our Design Goals: https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals

⭐ Suggestion

Add a tool generics so that some function parameters can enable file path type hints

some assets in ../assets

function getImageUrl(name:T<"../assets">) {
...
return ...
}

getImageUrl("// intellisense

📃 Motivating Example

Enable custom file path completion through generics

💻 Use Cases

1. What do you want to use this for?

When I used vite static resource introduction, I used a function to wrap it, but the function parameters could not achieve type hints like import.

the function like:

function getImageUrl(name:string) { // lost file intellisense
  return new URL(`./dir/${name}.png`, import.meta.url).href
}

2. What shortcomings exist with current approaches?

Only import statements support path completion and cannot be customized

3. What workarounds are you using in the meantime?

i make a vscode extension

Beginne mit der angeforderten Syntax für generische Typen und vergleiche sie mit der vorhandenen Pfadvervollständigung in Import-Anweisungen. Prüfe das Vite-Asset-Wrapper-Beispiel und den gemeldeten Workaround für die VS Code-Erweiterung; als abgeschlossen gilt die Aufgabe, wenn benutzerdefinierte Funktionsparameter eine Asset-Pfadvervollständigung bereitstellen, ohne das erzeugte JavaScript oder das Laufzeitverhalten zu ändern.
