hubdb

a github-powered database

Hubdb(options)

Create a new Hubdb instance. This is a database-like wrapper for a branch of a GitHub repository that treats JSON objects in that branch as documents.

Hubdb shines where GitHub itself makes sense: you can take advantage of GitHub's well-architected APIs and user permissions. A good example of hubdb in practice is in stickshift, where it powers a lightweight query storage for an analytics app.

Takes a configuration object with options:

• username the user's name of the repository. this is not necessary the user that's logged in.
• repo the repository name
• branch the branch of the repository to use as a database.
• token a GitHub token. You'll need to get this by OAuth'ing into GitHub or use an applicaton token.

Parameters

parameter	type	description
options	Object

Example

var db = Hubdb({
 token: 'MY_TOKEN',
 username: 'mapbox',
 repo: 'hubdb',
 branch: 'db'
});
db.add({ grass: 'green' }, function() {
  db.list(function(err, res) {
    // [{
    //   path: '2e959f35c6022428943b9c96d974498d.json'
    //   data: { grass: 'green' }
    // }]
  });
});
