I'm developing a node module. I need to pass the mongoose to my module to get three things ( mongoose.connection , mongoose.connection.db , mongoose.mongo ) out of it. index.js (myModule - the module I developed) function myModule(mongoose) { var db = mongoose.connection; var gfs = gridfsLockingStream(mongoose.connection.db, mongoose.mongo); this.someFunction = function() {//some code here} } module.exports = myModule; db.js (A user must use myModule like this) var mongoose = require('mongoose'); var myModule = require('myModule'); var dbUrl = 'mongodb://localhost:27017/gfsTestDB'; mongoose

I have been able to successfully upload images to mongoDB using GridFs. Below are images from my database: fs.files: fs.chunks: Below is the code I used to upload images: var Grid = require('gridfs-stream'); var mongoose = require("mongoose"); Grid.mongo = mongoose.mongo; var gfs = new Grid(mongoose.connection.db); app.post('/picture', function(req, res) { var part = req.files.filefield; var writeStream = gfs.createWriteStream({ filename: part.name, mode: 'w', content_type:part.mimetype }); writeStream.on('close', function() { return res.status(200).send({ message: 'Success' }); });

I am running express 4 using multer , gridfs-stream and mongoose with mongodb and I am attempting to upload a file and stream it to gridfs. The express route that does this is defined as: app.post('/uploadfile', function (req, res) { console.dir(req.files); // The mongodb instance created when the mongoose.connection is opened var db = mongoose.connection.db; // The native mongo driver which is used by mongoose var mongoDriver = mongoose.mongo; // Create a gridfs-stream var gfs = new Gridfs(db, mongoDriver); var file = req.files.myFile; var fileId = new ObjectId(); console.log("Creating

I am trying to figure out how I can post an image directly to GridFS without storing it anywhere on the server as a temporary file first. I am using Postman (chrome ext.) to post a file, and I manage to store this post as a file using: req.pipe(fs.createWriteStream('./test.png')); I am also able to store directly to GridFS from a readStream when the readStream is created from a file on the server. (see code) I have the following files, saveFromReq.js which listens for the POST and basically just passes this on to the savePic.js . saveFromReq.js: var express = require('express'); var app =
