How to Build a Simple CRM with Node.js & React

The majority of small businesses begin by using spreadsheets to manage leads. It functions initially, but it soon becomes disorganized, difficult to monitor, and ineffective. I therefore created a straightforward custom CRM to manage leads, monitor status, and maintain organization rather than depending on sophisticated tools. Here's a basic example of how to create one with React and Node.js. Tech Stack Node.js (Backend) Express (API) React (Frontend) MongoDB (Database) Core Features Add & manage leads Track contact details Basic status pipeline (New → Contacted → Closed) Backend (Node.js + Express) Create a simple lead model: const LeadSchema = new mongoose . Schema ({ name : String , email : String , status : String }); Basic API route: app . post ( ' /leads ' , async ( req , res ) => { const lead = new Lead ( req . body ); await lead . save (); res . json ( lead ); }); Frontend (React) Simple form to add leads: function AddLead () { const [ name , setName ] = useState ( '' ); const
