gridfstore

Mongoose with GridFS.
GridFS is convenient way to store files and it allows all mongodb features like clusters and sharding. This library is intended to help GridFS usage with nodejs and mongoose. It allows efficient way to store data, e.g. on the fly gzipped before storing and when gzipped data is read back gzip can be extracted on the fly.

Usage

var mongoose  = require('mongoose'),
   Schema = mongoose.Schema,
   gridfstore = require('../lib/gridfstore');
   
var myschema = new Schema({
  filename: {type: String, unique: true, required: true},
  length: {type: Number},
  metadata: {
    title: {type: String},
    owner: {type: String}
  }
});


gridfstore.store( {metadata: {filename: 'test1.txt', title: 'example', owner: 'jva'}}, 
                  'this is file content',
                  function(error, meta){
    //meta == whole metadata from gridfs
});
