# Start Developing To interact with the Keeta Network, we’ve built the **KeetaNet SDK** — a JavaScript and TypeScript-compatible library that works in multiple environments, including **Node.js**, modern **web browsers**, and other JavaScript runtimes. Whether you're building server-side applications or browser-based dApps, the SDK gives you everything you need to connect to the Keeta Network, manage accounts, send transactions, and more. ## Installation and Type Support The SDK includes full TypeScript definitions, so you’ll get autocomplete and inline type checking in modern editors. You can install it from npm: ```bash npm install @keetanetwork/keetanet-client ``` Type definitions are bundled with the package — no need to install anything extra. ## Using the SDK in NodeJS In Node.js, you can import the KeetaNet SDK like this: ```typescript import * as KeetaNet from '@keetanetwork/keetanet-client'; ``` Once imported, the SDK exposes several modules and utilities. The most important starting point is the `UserClient`, which lets you connect to the network and perform operations like sending tokens or fetching blockchain data. ```typescript const signer = KeetaNet.lib.Account.fromSeed(mySeed, 0); const client = KeetaNet.UserClient.fromNetwork('test', signer); ``` ## Using the SDK in the Browser You can also use the KeetaNet SDK directly in a browser using a script tag. Here's a basic example to get started: ```html ``` This is a good way to get started quickly without any build tools. Just keep in mind: **don’t store or expose real private keys or seeds in client-side code** in production apps.
