Contributing to Verdaccio

We are happy you wish to contribute this project, for that reason we want to board you with this guide.

How I contribute?

Ways to contribute

There are many ways to contribute to the Verdaccio Project. Here’s a list of technical contributions with increasing levels of involvement and required knowledge of Verdaccio's code and operations.

Please read carefully this document. It will guide you to provide maintainers and readers valuable information to boots the process solve the issue or evaluate your proposal.

Reporting a Bug

We welcome clear bug reports. If you've found a bug in Verdaccio that isn't a security risk, please file a report in our issue tracker. Before you file your issue, search to see if it has already been reported. If so, up-vote (using GitHub reactions) or add additional helpful details to the existing issue to show that it's affecting multiple people.

Check if there's a simple solution in the wiki.

Some of the most popular topics can be found in our wiki, that would be the first place to look at the topic you are interested.

Questions & Chat

We have tagged questions for easy follow up under the tag questions. Additionaly, I'd recommend to deliver questions in the new chat as #questions/#development channels at gitter.

Look at the past

  • Verdaccio is a fork of sinopia@1.4.0, thereforce, there is a huge database of tickets in the original projet. It's a good place to find answers.
  • Questions under the tag of sinopia or verdaccio at Starckoverflow might be helpful.

Using the issue tracker

The issue tracker is a channel were mostly users/developers post.

I want to report a bug

We considere a bug a feature that is not working as is described in the documentation. Before reporte a bug follow the next steps:

  1. Use the GitHub issue search — check if the issue has already been reported.

  2. Check if the issue has been fixed — try to reproduce it using the latest master or development branch in the repository.

Verdaccio still does not support all npm commands due either in the initial design were not considered important or nobody has request it yet.

Request Features

A new feature is always welcome, thus, analyse whether you ir idea fits in the scope of the project and elaborate your request providing enough context, for instance:

  • A wide description the advantages of your request.
  • It's compatible with npm and yarn?
  • You might implement your feature and provide a forked repository as example.
  • Whatever you have on mind 🤓.

Submitting a Pull Request

The following are the general steps you should follow in creating a pull request. Subsequent pull requests only need to follow step 3 and beyond:

  1. Fork the repository on GitHub
  2. Clone the forked repository to your machine
  3. Create a "feature" branch in your local repository
  4. Make your changes and commit them to your local repository
  5. Rebase and push your commits to your GitHub remote fork/repository
  6. Issue a Pull Request to the official repository
  7. Your Pull Request is reviewed by a committer and merged into the repository

Note: While there are other ways to accomplish the steps using other tools, the examples here will assume the most actions will be performed via the git command line.

1. Fork the Repository

When logged in to your GitHub account, and you are viewing one of the main repositories, you will see the Fork button. Clicking this button will show you which repositories you can fork to. Choose your own account. Once the process finishes, you will have your own repository that is "forked" from the official one.

Forking is a GitHub term and not a git term. Git is a wholly distributed source control system and simply worries about local and remote repositories and allows you to manage your code against them. GitHub then adds this additional layer of structure of how repositories can relate to each other.

2. Clone the Forked Repository

Once you have successfully forked your repository, you will need to clone it locally to your machine:

$ git clone --recursive git@github.com:username/verdaccio.git verdaccio

This will clone your fork to your current path in a directory named verdaccio.

You should also set up the upstream repository. This will allow you to take changes from the "master" repository and merge them into your local clone and then push them to your GitHub fork:

$ cd verdaccio
$ git remote add upstream git@github.com:verdaccio/verdaccio.git
$ git fetch upstream

Then you can retrieve upstream changes and rebase on them into your code like this:

$ git pull --rebase upstream master

For more information on maintaining a fork, please see the GitHub Help article Fork a Repo and information on rebasing from git.

3. Create a Branch

The easiest workflow is to keep your master branch in sync with the upstream branch and do not locate any of your own commits in that branch. When you want to work on a new feature, you then ensure you are on the master branch and create a new branch from there. While the name of the branch can be anything, it can often be easy to use the issue number you might be working on (if an issue was opened prior to opening a pull request). For example:

$ git checkout -b issue-12345 master
Switched to a new branch 'issue-12345'

You will then be on the feature branch. You can verify what branch you are on like this:

$ git status
# On branch issue-12345
nothing to commit, working directory clean

4. Make Changes and Commit

Before commit

At this point you have ready your changes, your new feature it's ready to be shipped, but, to avoid delays to merge, please be aware the build must past.

Before commit, run the test command:

npm test

It won't have eslint errors and all test must past. Then, and only then, you should push and ship your PR.

At the moment of this writing, there are plenty of warning to clean, but please warnings are not fails, but try to don't commit code with warnings

After testing your changes

Now you just need to make your changes. Once you have finished your changes (and tested them) you need to commit them to your local repository (assuming you have staged your changes for committing):

$ git status
# On branch issue-12345
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#        modified:   somefile.js
#
$ git commit -m "Corrects some defect, fixes #12345, refs #12346"
[t12345 0000000] Corrects some defect, fixes #12345, refs #12346
 1 file changed, 2 insertions(+), 2 deletions(-)

5. Rebase and Push Changes

If you have been working on your contribution for a while, the upstream repository may have changed. You may want to ensure your work is on top of the latest changes so your pull request can be applied cleanly:

$ git pull --rebase upstream master

When you are ready to push your commit to your GitHub repository for the first time on this branch you would do the following:

$ git push -u origin issue-12345

After the first time, you simply need to do:

$ git push

6. Issue a Pull Request

In order to have your commits merged into the main repository, you need to create a pull request. The instructions for this can be found in the GitHub Help Article Creating a Pull Request. Essentially you do the following:

  1. Go to the site for your repository.
  2. Click the Pull Request button.
  3. Select the feature branch from your repository.
  4. Enter a title and description of your pull request in the description.
  5. Review the commit and files changed tabs.
  6. Click Send Pull Request

You will get notified about the status of your pull request based on your GitHub settings.

Plugins

Plugins are Add-ons that extend the functionality of the application. Whether you want develop your own plugin I'd suggest do the following:

  1. Check whether there is a legacy sinopia plugin for the feature that you need at npmjs.
  2. There is a life-cycle to load a plugin you should keep on mind.
  3. You are free to host your plugin in your repository, whether you want to host within in our organization, feel free to ask, we'll happy to host it.
  4. Try a describe widely your plugin to provide a deeply understanding to your users.
