Saving Files and Sending them to client (NodeJS/Express/MongoDB/Mongoose)

How do I save some file in mongoose? For example I have a route for POST method /, and GET method /. Posting to / should save sent file to MongoDB database (mongoose), and Getting / should send the saved file. If file was an image how do I send it to client as image? (Is it a good practice to save raw file from user, or should I save them in mongodb - if so: how?).

First it's clear that you should have schema for your mongoDB. You can have it in SCHEMA.js file like this:

  module.exports = {
         model: function(Schema) {
          return new Schema({
             _id: { type: String, index: true, unique: true },
             updateDate: { type: Date, default: Date.now },
             data: String
            })
          }
  }

then you have for your requests you can do as below:

  router.post('/', function(req, res){
     var data = req.body.data;
     SCHEMA = require('/YOUR/SCHEMA/PATH').SCHEMA;

     SCHEMA.update({
       _id: data.id
     }, {
        data: data
     }, {
      upsert: true
      }, function (err) {
       if (err) {console.error('subs-on-userapps> failed update token, err=',err);}
     });
  })

In above part you get data form request and then insert it to you mongoDB.

** .update first search for you data in first part and with upsert:true option insert data if not exist before.

For have access to your data you have other route with Get method so:

      router.get('/', function(req, res){

          SCHEMA.findOne({QUERY})
               .execQ()
               .then(function(result) {
                    res.json({result: result})
               });

      })
