Server Side Pagination Using NodeJS, MongoDB and Angular Material Tables

Normally, we use Angular Material's data tables with pagination (mat-paginator) to list the results. This is not an efficient and optimal approach particularly if there are lots of records to show in the table. Angular Material's pagination just divides the received records into the paginated records. So, if we need to display lots of records in data tables, then the efficient and optimal approach is to use Server Side Pagination. Following, sections will demonstrate the server-side pagination using NodeJS (API), MongoDB (database), and Angular Material data tables. API using NodeJS and MongoDB Following is a sample code, written in NodeJS...

Profile Image Upload Functionality Using Angular and Node

In a recent project, I was working on a user profile component that can be used by the user to edit their profile information. A part of that component was a profile image section which lets the user change their profile picture. The profile picture is sent to the Node API via HTTP Post request, stored in a folder and then name/URL of the image is stored in the database. In this post, I will share the code on how to implement this functionality.

JavaScript Build Setup For Development of WordPress Blocks – NodeJS

JavaScript build setup helps to speed-up the development of WordPress blocks and creates the two main files i.e. build/index.js and build/index.asset.php which are used while developing the actual WordPress block inside plugin or functions.php of WordPress installation. The index.js file contain the compiled code (from ESNext and JSX syntaxt to plain JavaScript) for the actual WordPress block and index.asset.php file contains the dependencies and version information (generated from the used packages) to be injected while registering the WordPress block.

API Development Using NodeJS, ExpressJS and MySQL

In this tutorial guide, we will build a simple NodeJS API using ExpressJS and MySQL with basic CRUD (create, read, update, delete) operations. NodeJS is a JavaScript run-time environment used to execute JavaScript code outside browsers i.e on the servers. Visit our other blog post, to learn more about what is NodeJS? NodeJS along with ExpressJS (web framework for NodeJS) is a widely used combination to build RESTful API’s with a database query language like MySQL or MongoDB.
