require('ipfs-core') in ipfs package causes invalid typedef genration.

[Gozala]

We had to workaround the fact that following line:

js-ipfs/packages/ipfs/src/index.js

Line 4 in 16ecc74

const IPFS = require('ipfs-core')

produces dist/src/index.d.ts like

declare const IPFS: typeof import("ipfs-core/src");

Which then TS seems to fail to resolve, by changing require path to ipfs-core/src (see #3356)

We should figure out what is going on there and find a proper fix for that workaround.

I have setup an example TS project that pulls in the ipfs@next to try and figure this problem out. Running tsc --noEmit --traceResolution seems to suggest that TS attempts to look for node_modules/ipfs-core/dist/src as all the file types bun never as a directory (belowe is the relevant bits and noice removed

Loading module 'ipfs-core/src' from 'node_modules' folder, target file type 'TypeScript'.

But then TS seems to do something strange when trying to resolve as directory

And for some reason it never tries .ts, .d.ts extensions there, and just walks up the directory tree

node_modules/ipfs/dist/src/index.d.ts(2,35): error TS2307: Cannot find module 'ipfs-core/src' or its corresponding type declarations.

I think the problem is that once TS finally decides to look for dist/src/index.js it then goes and does path substitution once again based on typesVersions mapping dist/* and ends up looking for node_modules/ipfs-core/dist/src/dist/src/index.js instead of node_modules/ipfs-core/dist/src/index.js and fails.

I'm guessing it does not look for node_modules/ipfs-core/dist/src/dist/src/index.ts because there is no node_modules/ipfs-core/dist/src/dist directory so it skips any file lookups there.

I want to verify that issue still appears with typescirpt@next and if so, I'll report issue to the typescript project and see what can we do there.

[Gozala]

Verified that problem still there with typescript@next, will create a simple reproducible example that I can submit to typescript.

[Gozala]

Created two bug reports for typescript

• typeVersions substitution occurs multiple times causing resolution to fail microsoft/TypeScript#41284
• Module resolution fails when substituion path exists but original path directory does not microsoft/TypeScript#41281

I have also figured out a better solution to overcome this problem. Instead of using mapping like

"typesVersions": {
    "*": {
      "*": [
        "dist/*"
      ]
    }
  }

We could use mapping like:

"typesVersions": {
    "*": {
      "*": [
        "dist/*",
        "dist/*/index"
      ]
    }
  }

Which basically forces TS to lookup ipfs-core/src/index.

[achingbrain]

require('ipfs-core') in ipfs package no longer causes invalid typedef generation so this can be closed now, right?
