How to contribute

Prerequisites

You'll need to be in the dspace-angular github team to get the required access. Send your github username to Art Lowel (Atmire) to get an invite.
Fork the repository on Github

Have a look at the waffle board
Take an issue that’s in the ready section and has nobody assigned to it
assign yourself
When you start working on it, move the issue to the “in progress” section
Work on a separate branch for the issue on your fork
Add a link to the branch on your fork as a comment to the task on the waffle board. That way people can
When you’re ready, fire a pull request
in the comments of the pull request, write something akin to “this PR connect’s to #{the ID of the issue}”. That way the issue will be moved automatically to the review column.
When at least two people have reviewed and approved your PR, it can be merged in master.
You can also help out by reviewing the pull requests of other people
Please keep an eye on your pull request afterwards, the reviewers may have questions or comments about it, or ask you to tackle things in a different way, before they can approve it
Most discussions about the task or the pull request can happen through the github & waffle board comments.
If it’s more complex you can bring it up in one of these meetings.
After your Pull Request has been merged, drag the issue to the done column on the waffle board. (this can also be automated by adding “this merge closes #{the id of the issue}” in the merge comment.

A general introduction to Reactive Programming
There are a bunch of resources on RxJS’ github
Decision trees to find which operator to use when creating new sequences or using existing sequences → these are very useful during development

Universal is the angular sub-project that allows for angular apps to be rendered server-side
