npm i --global-style

[Denis Karavaev]

Hello!

Maybe I'm creating an issue in the wrong repository and real problem hides somewhere in dependencies. But I use dependency-tree as an entry point, so ... it looks like a good start.

Let's imagine that we have the following directory layout:

<project>
  |
  - package.json
  - node_modules
  |    |
  |    - package1
  |         |
  |         - index.js
  |
  - dist <- dependency-tree `directory` argument
       |
       - package.json
       - src
            |
            - index.js  <- dependency-tree `filename` argument (path.join(..., 'dist', 'src', 'index.js'))
       - node_modules
            |
            - package2
                 |
                 - index.js
                 - node_modules
                      |
                      - package1
                           |
                           - index.js                      

I invoke dependency-tree with the following arguments:

{
  directory: path.join(<project>, 'dist'),
  filename: path.join(<project>, 'dist/src/index.js')
}

And index.js requires package2 module. Which, respectively, requires package1 module. The folder where package2 resides was initiated by the following command: npm i --global-style, i.e. dependencies of modules from package.json are put into local node_modules folders of each package. In other words - I want to maintain old-style node_modules directory layout (let's pretend that I like duplicates :) ), where each top-level module holds its modules with itself.

And here is the problem. Top level directory () also contains node_modules with package1. And when I receive output from dependency-tree I have something like this:

.../dist/src/index.js
.../dist/node_modules/package2/index.js
.../node_modules/package1/index.js

NOT:

.../dist/src/index.js
.../dist/node_modules/package2/index.js
.../dist/node_modules/package2/node_modules/package1/index.js

If I'm not mistaken this algorithm assumes the second variant (it starts to look at the nearest node_modules folder and traverses to the root of the file system).

Am I wrong or something works not as expected? I have some checks after receiving list from dependency-tree. One of them is confirmation that common directory for all imports is dist folder. And this check started to fall when I tried to use npm i command inside dist folder with --global-style argument. Without it (when package1 folder resides at the same level as package2) all works as expected.

Can you confirm that I'm wrong :) or help to resolve the issue?
Thanks in advance! CC: @mrjoelkemp
