Modern MEAN Stack Tutorial with Docker (Angular, Node, Typescript and Mongodb)

The MEAN stack allows you to build complete applications using one programming language: JavaScript. In this tutorial, we built upon the first part (Creating an Angular app) which built the front-end, and this part builds the backend with a RESTful API and Database.

REST API with Node.js

We are going to use express generator and create a folder called server.

First install the generator packages:

1
npm i -g express-generator

Note: You should have Node and NPM/Yarn installed.

REST API using ExpressJS

Now let’s scaffold the app using the generator:

1
express server -e

Let’s install all its dependencies on the server folder:

1
cd server && npm i

and now let’s make sure it’s working:

1
npm start

Go to localhost on port 3000 and make sure you can see a “Welcome to Express”

http://localhost:3000/

Creating a host alias for the server

We want to run the server to work regarless of the enviroment where we run it. (It will be useful for Docker later on)

For that we can create an alias by editing the hosts:

  • Windows: c:\windows\system32\drivers\etc\hosts
  • Linux/Mac: /etc/hosts

Once you can open the file, you drop the following line at the end:

#docker #mean stack #node #angular #typescript #mongodb

Authentication In MEAN Stack - A Quick Guide

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.

To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.

Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Let me show what I mean…

There are template parser errors that can be easy catched by stackblitz

It gives me some information but I want the error to be highlighted

What Is MEAN STACK and Scope of MEAN STACK Developer ?

What is MEAN Stack Developer?
MEAN Stack Developer is a programmer who operates on the MEAN stack. He works on the backend plus the front end of the application. They are all JavaScript based and therefore a MEAN developer should have excellent JS knowledge, for which you can join MEAN Stack Online Training Program.

Skillets of MEAN Stack developer
• Knowledge of working on the Front-end and Back-end processes
• Work with HTML & CSS
• Understanding of programming templates and architecture design guidelines
• Knowledge of continuous integration, web development, and cloud technologies
• Excellent understanding of DB architecture
• Knowledge of SDLC and experience developing in an Agile environment
• Collaborate with the IT team to build robust systems to support business objectives
• Hands-on experience on Mongo, Angular, Express, Node.
Future of MEAN stack Developer

Being, a Mean stack developer is a highly desirable, challenging vocation. So, if you are ready to work on the diverse skill set and have the experience of working with various code languages and application, then you will become successful MEAN stack developer.

Scope of MEAN stack developer

MEAN Stack Development is the best career prospect today with unlimited growth and scope. The national Indian median salary was around 76K $ pa according to Glassdoor.com. All you need to do is get cracking on your skill set by joining MEAN Stack course in Delhi, earn your certification and through your job experience and continued experiential learning keep pace with newer iterations in technology.
Developers are available in various process streams like Backend, Frontend, Database, Testing, and Mobile Apps. Older practices were that as you gain experience and expertise you would pursue specialization and progress your career in that direction.

MEAN Stack (Angular 10) Tutorial: Upload Image File

The following tools, frameworks, modules, and libraries are required for this tutorial:

  1. Node.js
  2. MongoDB
  3. Angular 10
  4. Angular CLI
  5. Express.js
  6. Mongoose.js
  7. Multer.js
  8. Angular Material Input File
  9. Terminal or Command Line
  10. IDE or Text Editor (we are using VSCode)

Before the move to the main steps of this tutorial, make sure that you have installed Node.js and MongoDB on your machine. You can check the Node.js version after installing it from the terminal or Node.js command line.

node -v
v12.18.0
npm -v
6.14.5

You can watch the video tutorial from our YouTube channel here. If you like it, please share, comment, and subscribe to this channel.

Let’s get started with the main steps!

Step #1: Create a New Node Express.js App

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. To create the Express.js app, we will be using the Express generator. Type this command to install it.

sudo npm install -g express-generator

Next, create an Express.js app by typing this command.

express mean-uploader --no-view

Go to the newly created mean-uploader folder then install all NPM modules.

cd ./mean-uploader
npm install

Open this Express.js project with your IDE or Text Editor. To use Visual Studio Code, type this command.

code .

Now, we have this Express.js app structure for the mean-uploader app.

.
|-- app.js
|-- bin
|   `-- www
|-- node_modules
|-- package-lock.json
|-- package.json
|-- public
|   |-- images
|   |-- index.html
|   |-- javascripts
|   `-- stylesheets
|       `-- style.css
`-- routes
    |-- index.js
    `-- users.js

To check and sanitize the Express.js app, run this app for the first time.

nodemon

or

npm start

Then you will see this page when open the browser and go to localhost:3000.

To make this Express.js server accessible from the different port or domain. Enable the CORS by adding this module.

npm i --save cors

Next, add this import to app.js after other require.

var cors = require('cors');

Then add this line to app.js before other app.use.

app.use(cors());
