Can I go off the road to answer Go(Google's Golang) ? It's a perfect blend of power and simplicity. The best thing about Golang are: Compiled language Statically typed (Learn some good habits) Supports multi-threading (Harness the full power of your machine) Supports the use of pointers (do not allow pointer arithmetic) Not an object-oriented language but supports Interfaces No exceptions only errors (No more try catch) Automatic garbage collection (so beginners can jump into it) Better things are: The whole toolchain is inbuilt. Testing framework is there, no need to search for it Code-linting and formatting is also there Quick to learn and the provided toolchains support rapid development. Do you know? Both Docker and Kubernetes are built using Golang. A good competitor is Rust but for those who love to clear their garbage on their own.

Thanks! I changed the value of BATCH_INSERT_VALUE from 50000 to 1000 and it was faster. Just read the limit of insertMany() is 100

So I came up with a very simpe code snippet which is as follow: const fs = require ( 'fs' ); const mongoose = require ( 'mongoose' ); const JSONStream = require ( 'JSONStream' ); const User = require ( './src/models/User' ); const config = require ( './config.json' ); mongoose.connect(config.MONGODB_URI, { poolSize: config.DB_POOL_SIZE }); mongoose.Promise = global.Promise; const db = mongoose.connection; let arrayOfUsers = []; db.on( 'open' , () => { console .log( 'Connected to mongo server.\n' ); process.stdout.write( 'Processing.' ); const dataStreamFromFile = fs.createReadStream( ` ${__dirname} /users_large.json` ); dataStreamFromFile.pipe(JSONStream.parse( '*' )).on( 'data' , async (userData) => { arrayOfUsers.push(userData); if (arrayOfUsers.length === config.BATCH_INSERT_VALUE) { dataStreamFromFile.pause(); await User.insertMany(arrayOfUsers); arrayOfUsers = []; process.stdout.write( '.' ); dataStreamFromFile.resume(); } }); dataStreamFromFile.on( 'end' , async () => { await User.insertMany(arrayOfUsers); // left over data console .log( '\nImport complete, closing connection...' ); db.close(); process.exit( 0 ); }); }); db.on( 'error' , (err) => { console .error( 'MongoDB connection error: ' , err); process.exit( -1 ); }); Note: Inserting 50k records is also a bit slow. Will keep on trying !

Superb !

The core of MEAN Stack is JavaScript, focus on JS because it is the language of the web. Don't limit yourself to a particular frameworks because frameworks will come and go. The language will stay. From the perspective f getting a job, the market is flooded with JavaScript jobs so I will not be a problem. You can move to Reactjs and react native for mobile apps is better than any other JS Framework for mobiles. JS Fullstack jobs has starting of 500,000 INR Hope that helps !

Ahh, parcel seems to be interesting. Thanks for the link

This was of great help, I hope to get such great helpful answers from you in the near future. thanks a lot :)

I will wait for your detailed answer. Also "modifiedAt, createdAt" are always there for every table just not showing it in diagram

I have used SemanticUI extensively, it has got a lot of great components and you have got lots of customization options. Apart from that you can checkout Ant Design for react as well. Justin Friebel : I would like to draw you attention towards Grommet as well. have a look : http://grommet.io/docs/icon
