About dependencies in package.json

[ryouaki]

Expected Behavior

What did you want to happen?

Actual Behavior

In package.json，have three dependencies：

  "dependencies": {
    "commander": "^2.18.0",
    "gettext-parser": "2.0.0",
    "gettext-to-messageformat": "^0.3.0"
  },
  "devDependencies": {
    "jed": "~1.1.1",
    "messageformat": "^2.0.4",
    "nodeunit": "*"
  },

Steps to Reproduce

When I use po2json on my project，it will install two dependencies which has two different version like "commander@2.20.0" and "commander@2.15.1", and will both build in my production Javascript files.

Additional Data

change to peerdependencies will fix this problem。

  "peerDependencies": {
    "commander": "^2.18.0",
    "gettext-parser": "2.0.0",
    "gettext-to-messageformat": "^0.3.0"
    "jed": "~1.1.1",
    "messageformat": "^2.0.4",
    "nodeunit": "*"
  },

I felt a little weird removing the dependencies entirely, but I added some to peer dependencies in the latest beta. Let me know if that helps you @ryouaki

Thank you for your replay , yes it will help me and fix my problem.

I saw your change, But I think move to peer dependencies is better。

If still keep in dependencies, I have a package need "commander" with version "1.0.0", and in po2json is version 2.18.0, when I run npm install --production, it will install 2.18.0 and 1.0.0 form my project. And will get risk for my project.

If you are using both versions in your project, both will be installed. The risk would be install one only. You need to go ahead with one of both if you want to remove the redundancy: upgrade your commander-dependent code in your project in order to use 2.18.0 only or stop using po2json because does not meet your dependencies versions.

Sorry @mikeedwards, but I'm getting always the next warning message installing po2json:

warning " > po2json@1.0.0-beta-3" has unmet peer dependency "commander@^6.0.0".
warning " > po2json@1.0.0-beta-3" has unmet peer dependency "gettext-parser@2.0.0".
warning " > po2json@1.0.0-beta-3" has unmet peer dependency "gettext-to-messageformat@0.3.1".

This redundancy in the dependencies of the project doesn't have any sense. Are peer or normal dependencies? Please, consider remove peerDependencies in package.json. I think that this change has been a misconception of what peer dependencies are.
