How to Implement Server-Side Search in Node.js and MongoDB Using $regex
When building scalable web applications, querying and filtering large datasets directly from the database is essential. Client-side filtering only works for small lists, but as your database grows, you need server-side search . In this tutorial, we will walk through how to build a dynamic search feature in a Node.js application using Express, EJS, Mongoose, and MongoDB's $regex operator . Prerequisites & Tech Stack Make sure you have Node.js and MongoDB installed on your system. We will use the following packages: Express : Fast web framework for handling HTTP requests. Mongoose : Elegant ODM library for MongoDB and Node.js. EJS : Embedded JavaScript templating engine for rendering dynamic views. Body-Parser / Express Urlencoded : For parsing incoming form and query data. Step 1: Set Up the Project Folder Open your terminal or command prompt and run the following commands to create and enter your project directory: mkdir searching cd searching Next, initialize a new No...
