I have a plugin for my bundler (in my case Vite), that loads files, that are neither JS nor TS (the plugins simply transforms the file to valid JavaScript on import).
I want to provide typescript declarations for those non-JavaScript files.
Things I have already tried / considered
Wildcard module declarations
As described here
I could go with a similar approach to what Vue does for example:
declare module '*.vue' {
export default MyFancyType;
}
This does not work for me, because all files have different contents and should therefore have different types.
Using declare module with paths
I have also tried using declare module with a relative and absolute path of the file.
This won't work for two reasons:
- TS errors with Ambient module declaration cannot specify relative module name.
- Relative paths won't work anyways, because I could have imports from multiple TS files with different relative paths.
Adding a myfile.ext.d.ts file next to the imported file
This works in theory, but in my case that would mean A LOT of files. So this is undesirable.
