CRUD Application with LMDB and Bun

This project implements a fully functional CRUD application using Bun and LMDB. The server-side code is written in TypeScript and follows an object-oriented approach. The application performs all four CRUD operations (Create, Read, Update, Delete) on an LMDB database stored in the base.mdb file.

The client-side interface is a simple table with two fields: id and title. Users can add, edit, and delete records through a modal window. The client communicates with the server via AJAX requests to the CRUD endpoints.

Project Structure

/data/base.mdb 
/index.ts
/index.html
  • Server: The server is built with Bun and runs on port 5000. It provides an API for handling CRUD operations using LMDB.
  • Client: A simple front-end interface allows users to interact with the data through a dynamic HTML table, using Cheerio for server-side HTML manipulation.

Features

  • Object-Oriented Design: The project is written using OOP principles to ensure maintainability and scalability. A universal database connector is provided for interacting with LMDB.
  • CRUD Operations: Supports creating, reading, updating, and deleting records in the LMDB database.
  • AJAX Communication: The front-end communicates with the server asynchronously via AJAX requests to perform CRUD operations.
  • Cheerio for Dynamic Content: The table and modal content are dynamically generated and updated using the Cheerio library on the server side.
  • Client-Server Architecture: The client-side interface updates dynamically based on the data retrieved from the LMDB database via the server.

Requirements

  • Bun: This project requires the Bun runtime for execution.
  • LMDB: Lightning Memory-Mapped Database is used for data storage.
  • Cheerio: A lightweight, fast HTML parser used for handling dynamic HTML content.

How to Run

  1. Clone the repository.
  2. Install Bun and dependencies:
bun install
  1. Run the project with the following command:
bun run index.ts
  1. The server will start on http://localhost:5000, where you can interact with the CRUD interface.

Endpoints

  • Create: POST /create
  • Read: GET /read
  • Update: POST /update
  • Delete: POST /delete

Front-End Table

  • Displays the id and title of records stored in the LMDB database.
  • Users can add, edit, and delete records via the modal window.

This project was created using bun init in bun v1.1.27. Bun is a fast all-in-one JavaScript runtime.
