MongoDB Text Search With Node.js

Fuzzy Text Search And Autocompletion With MongoDB And Node.js

• Exact match text search with self-deployed MongoDB
• Fuzzy text search with MongoDB Atlas
• Text autocompletion
• Sort search results by score
• Search through multiple text fields
• Limit search results to specific country code
• Populate database with fake users
• Small user interface for searching

• Node.js
• TypeScript
• Docker
• Self-deployed MongoDB or MongoDB Atlas

Recommended OS: Linux

Requirements: Node.js, Docker

Setup

• npm install (Install NPM dependencies for server)

Self Deployed Search

• docker-compose -f docker-compose.yml up --build (Start services)
• npx ts-node fake-data.ts .env.local (Add fake data to MongoDB)
• mongodb://admin:password@localhost:27017 (MongoDB Compass connection URI)
• http://localhost:3000/search?query=gilbert (Basic search)

MongoDB Atlas Search

• Create MongoDB Atlas cluster
• Create a user with password and set MONGODB_USERNAME and MONGODB_PASSWORD in .env.atlas
• Create API Key for your project
  1. Go to Project Settings
  2. Select Access Manager
  3. Select API Keys
  4. Create API Key
  5. Set Project Permissions to Project Search Index Editor
  6. Set MONGODB_ATLAS_PUBLIC_KEY and MONGODB_ATLAS_PRIVATE_KEY in .env.atlas
• docker-compose -f docker-compose.yml up --build (Start services)
• npx ts-node fake-data.ts .env.atlas (Add fake data to MongoDB)
• http://localhost:3001/search?query=gilbert (Fuzzy search)

User interface

• cd client && npm install (Install NPM dependencies for client)
• cd client && npm run dev (Start user interface in development mode, http://localhost:4000)

Cleanup

• docker-compose -f docker-compose.yml rm -s -f -v (Stop and remove Docker containers)

• self-deployed-api.ts (Node.js API to fetch search results from self-deployed MongoDB)
• atlas-api.ts (Node.js API to fetch search results from MongoDB Atlas, which has more features)
• fake-data.ts (Script to populate MongoDB with fake data)
• util.ts (Utilities for TypeScript and MongoDB)
