IOTA TypeScript SDK Quick Start

The IOTA TypeScript SDK is a modular library of tools for interacting with the IOTA blockchain. Use it to send queries to RPC nodes, build and sign transactions, and interact with a IOTA or local network.

Installation​

npm i @iota/iota-sdk

Network locations​

The following table lists the locations for IOTA networks.

info

It is suggested to use dedicated nodes/shared services rather than public endpoints for production apps with high traffic volume.

You can either run your own full nodes, or outsource this to a professional infrastructure provider (preferred for apps that have high traffic).
