[BUG] Some path which omits '/index' should not be skipped

[feng9017]

I found that some dependency ../store/mp was ignored by Madge 6.0.0 . But the dependency is clearly stated. I checked it by use '--debug' mode, found this:

tree skipping an empty filepath resolution for partial: ../store/mp +1ms

Actually, the full paths should be ../store/mp/index, but eslint will give a warning like this :

Useless path segments for "../store/mp/index", should be "../store/mp"eslint[import/no-useless-path-segments](https://github.com/import-js/eslint-plugin-import/blob/v2.27.5/docs/rules/no-useless-path-segments.md)

import/no-useless-path-segments is a common eslint plugin. I think it is necessary to check somePath/index when Madge find that somePath is empty.

Adding "/index" to some path resolves madge skipping files

I have file extract.test.ts with imports:

import { ... } from "../../model"
import { ... } from "./extract"

And my madge result with --json for this file is:

{
  "call.ts": [],
  "extract.test.ts": [
    "extract.ts"
  ],
  "extract.ts": [
    "call.ts"
  ]
}

But if I change model import for ../../model/index:

{
  "../../model/***.ts": [],
  "../../model/index.ts": [
    "../../model/***.ts",
  ],
  "call.ts": [],
  "extract.test.ts": [
    "../../model/index.ts",
    "extract.ts"
  ],
  "extract.ts": [
    "call.ts"
  ]
}

same here, index.ts files seems to be ignored: all imports of dirs with index.ts are skipped(

is there any way to fix it?

Facing the same issue and digging a bit.
I think it is a problem with dependency-tree, likely dependents/node-dependency-tree#118, which Madge uses to get its dependencies. At least the "skipping" message comes from there.

Trying to dig further into dependency-tree to see whether this is just an option to pass or a deeper issue…

[Jym77]

OK, I think this is a dependency-tree problem that was fixed in v10, madge is still running v9 and thus has the problem.

• Adding a console.log statement to see the result of the call to DependencyTree at https://github.com/pahen/madge/blob/master/lib/tree.js#L121, I do not get the dependency:

  {
    '/mnt/c/Projects/a11y/alfa/packages/alfa-css/src/calculation/index.ts': {}
  }
  

• Calling, with the same config, DependencyTree directly, and showing the result,
  • with v10.0.1 to v10.0.9 (somehow, v10.0.0 crashes), I get the dependency:

    {
      '/mnt/c/Projects/a11y/alfa/packages/alfa-css/src/calculation/index.ts': {
        '/mnt/c/Projects/a11y/alfa/packages/alfa-css/src/calculation/math-expression/index.ts': {
          '/mnt/c/Projects/a11y/alfa/packages/alfa-css/src/calculation/math-expression/math.ts': [Object]
        }
      }
    }
    

  • same with v9.0.0 (no other v9.* version) of dependency-tree, I do not get the dependency:

    {
      '/mnt/c/Projects/a11y/alfa/packages/alfa-css/src/calculation/index.ts': {}
    }
    

I'm not really able to see which update of dependency-tree did the trick, but it seems to be the root cause…
https://github.com/dependents/node-dependency-tree/releases/tag/v10.0.0

[Jym77]

…which should make it easy to fix 😁
The latest release of madge, v6.1.0 is from June '23.
dependency-tree has been updated to v10.0.9 in October '23.

So, I assume that simply making a new release would solve the problem… <= @pahen

@Jym77, I ran into this same issue and I used package.json#pnpm.overrides to enforce [email protected] to be used by madge and it still did not work for me :( Import identifiers that had implicit "index" files still showed up as warnings in madge because they could not be resolved.
Example output of madge with dependency-tree@10:

pnpx madge --warning --circular ./src/**/*

Then if I update all import specifiers with /index:

pnpx madge --warning --circular ./src/**/*

Is there anything else you did to get it to work?

Is there anything else you did to get it to work?

Since I am only at the "experiment and play" step, I brutally edited madge.js in my node_modules to accept a DependencyTree parameter instead of using its own, installed 10.0.9 locally, and injected it that way.
Not my proudest hack 🙈
And definitely won't work once I try to actually use this… Or when try to use madge from command line rather than a script.

[kirbysayshi]

I can confirm that upgrading dependency-tree >= 10 fixes the issue! Madge 6.1.0. Since I'm using pnpm I did the following in my package.json:

 "overrides": {
      "madge>dependency-tree@<10": "10"
    }

I went from 1000s of skipped files to 7!

[Jym77]

For yarn, the workaround in package.json is:

"resolutions": {
    "dependency-tree": "^10.0.9"
  }

[Vovan-VE]

Thanks for workaround!
npm:

  "overrides": {
    "madge": {
      "dependency-tree": "^10"
    }
  },

FYI, updating to madge 7.0.0 fixed this for me (no need for custom resolution anymore). The correct dependency-tree is now a dependency 🎉

Nice :)
