MongoFileUpload

MongoFileUpload is a simple npm package to upload files to mongodb. It simply stores the file chunk to MongoDB as a document. It can be used for the profile and simple document upload. As we can store max 16MB data to a document so we cannot store more then that in one document. It can be used to store files with other text fields in the same document.

• Creates an object for a file with the details like name,extension,content and size
• Can be saved multiple files at a time but the sum of sizes of all files and fields, should be less then 16MB
• It uses promises to handle the response

Features!

• Easy to use
• Can upload multiple files

Installation

Install the dependencies and devDependencies and start the server.

$ npm i mongofileupload

How to use

1. Connect to Mongodb collection

const {fileDetails,mongoUploadOne,mongoRetreive}  = require('mongofileupload');
const MongoClient = require('mongodb').MongoClient

const connectionString = MONGO_URI;
MongoClient.connect(connectionString, { useUnifiedTopology: true })
const Collection = client.db('test').collection('test')

2. Create a object/document to store in collection

  var documentToSave = {};
  documentToSave.name = "abc";
  documentToSave.profile = new fileDetails('prof.png','./profile.png');
  documentToSave.resume = new fileDetails('res.pdf','./resume.pdf');
  documentToSave.email = "[email protected]";
  
  //save the document 
  mongoUploadOne(Collection,documentToSave).then((result)=>{
    console.log(result);
  })
  .catch((err)=>{
    console.log(err);
  });

3. To retreive

  mongoRetreive(Collection).then((result)=>{
        //to save a file 
      fs.writeFile('/home/coder/Music/'+result[0].resume.filename,result[0].resume.content, "binary", function(err) {
        if(err) {
            return console.log(err);
        }
        else console.log("The file was saved!");
      });
