githubble's Introduction

GitHubble

The Idea of this Web-App is to discover the GitHub Galaxy. You start at a fixed point (e.g. your GitHub Account) and travel throughout the GitHub Repositories.

There are several kinds of nodes:

User - the basic GitHub User Account (identified by Name and Avatar)
Organisation - Organisations hold Teams of Users (identified by Name and Avatar)
Repositories - small Nodes owned by Organisations or Users.

Concepts are still in Development.

Uses

d3.js
Play2 Scala
public GitHub Api

Started at innoQ Summer of Code 16./17. August 2014.

adding d3.js lib to assets

At the moment, if we load the Site over https there is an error:

Laden von gemischten aktiven Inhalten "http://d3js.org/d3.v3.min.js" wurde blockiert.
ReferenceError: d3 is not defined


var force = d3.layout.force()


index.html (Zeile 56, Spalte 7)

So we should add the JS Lib to the application assets. That means, that we need to make a template out of index.html and use the Play Asset functions.

[Backend] use oAuth for creating less limitet requests...

Implement EndPoint for Receiving oAuth Response (for client_id)
add new Application here https://github.com/settings/applications/new => secret
make Calls with client_id and secret
https://developer.github.com/v3/#unauthenticated-rate-limited-requests

[Backend] give Status Code 404, if queried element does not exists.

If you query an element like user http-nowenrowneor the backend should give you http status 404 instead of 500 as it is now.

[Backend] use conditional Requests for GitHub API Calls

https://developer.github.com/v3/#conditional-requests

[Frontend] append Childs onClick

Greate switch contxt onClick of nodes.

// Toggle children on click.
function click(d) {
  if (!d3.event.defaultPrevented) {
    if (d.children) {
      d._children = d.children;
      d.children = null;
    } else {
      d.children = d._children;
      d._children = null;
    }
    update();
  }
}

[Frontend] add call history

show a nice list of previous visited elements...

Maybe we can use the Browser History API?
Otherwise we need to store it in a cockie / on the Backend... that wouldn't be nice :-/

[Frontend] creating a concept of displaying a Repository

Forks
Stars
Commits
...

Would be a nice feature.

[Backend] show correct http Status code and error message, when API rate limit exceeded

That would be status code 403 instead as 500 as it is now

And we could also use this JSON:

{"message":"API rate limit exceeded for 109.91.246.46. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)","documentation_url":"https://developer.github.com/v3/#rate-limiting"}
