Create Nodejs JavaScript Microservices Project with Postgres Database in Docker Container

In this video we will create microservices in Nodejs JavaScript with postgres database deployed in docker container. Using Express, PG & Sequelize ORM JavaScript module in this project. We will connect microservices running in node server with postgres sql database running in docker container. I will also show step-by-step code to create microservices in Nodejs. I will explain Sequelize ORM module in JavaScript. I will explain how to connect JavaScript microservice to postgres db running in docker container. ** Chapter Timestamps ** 0:00 Introduction to Nodejs Javascript Microservices with Postgresdb 0:52 Agenda of this tutorial 2:46 Architecture Diagram of tutorial explained 6:37 Prerequisite of Nodejs microservice tutorial 7:36 Basic of Docker Container & Docker HUB repository 8:55 Download Postgre DB TAG from Docker HUB repository 10:31 Run Postgres DB in Docker Container 18:21 Understanding of Nodejs modules like Express, PG, Sequelize 19:57 GIT Repository of this project 21:12 Coding Microservice in Nodejs 22:43 Coding database entity and Repository components 32:34 Coding business layer components 28:00 Coding controller components 40:48 Coding routes components 43:12 Coding main app component 45:49 Coding config components 46:35 Running Microservice app 48:00 Testing Microservices end points 57:13 Stopping the docker container 59:00 Summary of Nodejs microservice with postgres sql ** Important Nodejs Packages or Modules ** • Express - Express is a node js web application framework that provides broad features for building web and mobile applications. It is used to build a single page, multipage, and hybrid web application. It's a layer built on the top of the Node js that helps manage servers and routes. • Sequelize - Sequelize is a Node.js-based Object Relational Mapper that makes it easy to work with MySQL, MariaDB, SQLite, PostgreSQL databases, and more. • PG - Non-blocking PostgreSQL client for Node.js. Pure JavaScript and optional native libpq bindings. • Body-parser - Body-parser parses an HTTP request body. Specifically in the context of a POST, PATCH, or PUT HTTP requests where the information is contained in the body. body-parser allows you to access req. Also helps in parsing the DB URLs. • UUID - UUID is used to generate 16-byte unique value. This is used for the primary keys. ** Docker Container ** A container is an isolated environment for your code. This means that a container has no knowledge of your operating system, or your files. It runs on the environment provided to you by Docker Desktop. This is why a container usually has everything that your code needs in order to run, down to a base operating system. ** Docker File ** A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. This page describes the commands you can use in a Dockerfile ** Docker Image ** Docker is used to create, run and deploy applications in containers. A Docker image contains application code, libraries, tools, dependencies and other files needed to make an application run. When a user runs an image, it can become one or many instances of a container. ** Docker HUB Repository ** Docker Hub is a hosted repository service provided by Docker for finding and sharing container images with your team. #nodejstutorial #postgres #dockertutorial ** CHECK OUT OUR OTHER VIDEOS ** Difference between Monolithic and Microservice Architecture https://youtu.be/AkLxyMUyGg0 Spring boot project setup: https://youtu.be/bsgA20eJKxs Spring Boot Microservice with postgres database Project: https://youtu.be/iw4wO9gEb50 Prepare Docker file, Container and Build Image: https://youtu.be/g_pdTzjnuso Deploy Docker Image AWS Elastic Container Service: https://youtu.be/ZlR5onuwZzw Solid Principle Tutorial https://youtu.be/7d4ZrBfXweE ** CHECK OUR PLAYLISTS ** Microservice Architecture and Microservice Design Patterns Tutorial https://youtube.com/playlist?list=PL2NZAYdLkYvgY74JFZMuluTJy-J_A_8NA Spring Boot Complete Tutorial https://youtube.com/playlist?list=PL2NZAYdLkYvg_VlNmszrb-Um0wRx5yGDF Docker Containers Complete Tutorial https://youtube.com/playlist?list=PL2NZAYdLkYvhZQo2VTVCSug_zVjekNodi Java Design Pattern Complete Tutorial with Examples https://youtube.com/playlist?list=PL2NZAYdLkYvglL0xl-4tgBAribrcjeuNH ** ABOUT OUR CHANNEL ** CodeOneDigest is a youtube channel that produces videos on programming languages, cloud and container technologies, Software design principles, Java frameworks in English and Hindi languages.
