Create Nodejs Javascript Microservices with PostgresDB | Nodejs Express PG Sequelize Tutorial
In this video we will learn how to create microservices in javascript Nodejs with postgres database using Express PG & Sequelize ORM packages. I will also show step-by-step code to create microservices in Nodejs with postgres db. I will explain Sequelize ORM for many RDBMS for nodejs.
** Important Nodejs Javascript 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.
