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 an 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).
