Package Exports

branchdb-client
branchdb-client/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (branchdb-client) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Client-BranchDB

Stage: Building Version(1.0.0)

Introduction 🚀

@branchdb/client is the official Node.js client SDK for Branch DB, a lightweight, in-memory key-value database. This SDK handles all the complexities of network communication and protocol serialization, allowing you to interact with your Branch DB server using a simple, asynchronous Methods.

Features ✨

Persistent Connections: Manages a single, persistent TCP connection to your Branch DB server. Asynchronous API: All methods return Promises, making it easy to integrate into modern Node.js applications using async/await.
Type-Safe Responses: Handles the deserialization of the server's custom binary protocol, providing structured responses with status codes and payloads.
Data Manipulation: Provides high-level methods for all core database operations, including SET, GET, DEL, TTL, GETALL, FLUSH FORCE, EXISTS, PERSIST and EXPIRE.

Installation 📦

To install the SDK, run the following command in your project directory:

npm install @branchdb/client

Getting Started 🧑‍💻

This example shows you how to connect to your Branch DB server and perform basic operations.

Prerequisites

The Branch DB server must be running and listening on a specified port (default: 1981).

Example Usage

import { Branch } from "@branchdb/client";

const config = {
  host: process.env.BRANCH_DB_HOST || "localhost",
  port: parseInt(process.env.BRANCH_DB_PORT || "1981"),
};

const client = new Branch(config);

async function main() {
  try {
    await client.connect();
    console.log("Successfully connected and authenticated!");

    const setResponse = await client.set("user:101", '{"name": "Alice"}', 60);
    console.log("SET response:", setResponse);

    const getResponse = await client.get("user:101");
    console.log("GET response:", getResponse);

    const delResponse = await client.del("user:101");
    console.log("DEL response:", delResponse);
  } catch (error) {
    console.error("An error occurred:", error);
  }
}

main();

Methods Reference 📚

The Branch client provides the following asynchronous methods:

Method	Description
connect()	Establishes a connection with the server.
set(key, value, ttl?)	Sets a key-value pair, with an optional TTL in seconds.
get(key)	Retrieves the value for a given key.
del(key)	Deletes a key-value pair.
exists(key)	Checks if a key exists.
ttl(key)	Returns the remaining time to live for a key.
expire(key, ttl)	Sets a new TTL for an existing key.
persist(key)	Removes the TTL from a key.
getall()	Returns a list of all keys in the database.
flush()	Deletes all keys from the database.
