git-object

Simple library to retrieve git objects from a repository.

Usage

To retrieve a blob from a git repository use the following:

var git = require('git-object');
 
// retrieve a blob
 
git('.', 'master', 'index.js', function(err, object){
  if (err) return console.log(err);  // fail
  if (object.isBlob()) {
 
    // create read stream an use it
 
    object.createReadStream().pipe(process.stdout);
  } else {
    console.log('not a blob');
  }
});

Reading of a tree is just as simple as this:

// retrieve a tree
 
git('.', 'master', 'lib/', function(err, object){
  if (err) return console.log(err);  // fail
  if (object.isTree()) {
    object.contents(function(err, contents){
      if (err) return done(err);
      contents.should.eql([
        'git-object.js'
      ]);
      done();
    });
  } else {
    console.log('not a tree');
  }
});
