OurDB Server

OurDBServer is a lightweight key-value store server built in V, designed for simplicity and performance. It provides basic CRUD operations with security features such as host and operation restrictions.

Features

• Supports set, get, and delete operations.
• Allows configurable host restrictions.
• Middleware for logging and security.
• Incremental mode for automatic ID assignment.
• Configurable storage options.

Installation

• Ensure you have V installed on your system:

Usage

Starting the Server

You can start the server using the following command:

mut server := new_server(OurDBServerArgs{
    port:               3000
    allowed_hosts:      ['localhost'] // Add more hosts as needed
    allowed_operations: ['set', 'get', 'delete'] // Add more operations as needed, these are the current supported operations
    secret_key:         'your-secret-key'
    config:             OurDBConfig{
        path:             '/tmp/ourdb'
        incremental_mode: true
        reset:            true
    }
}) or { panic(err) }
server.run(background: false )
