## What it is
The official TypeScript SDK for the Fuel blockchain network, providing providers, wallets, transaction crafting, contract deployment, and Sway ABI type generation. It includes a `fuels` CLI for scaffolding fullstack dApps, building Sway programs, and running local nodes with hot reload.

## Use cases
- connect to the Fuel network from TypeScript
- deploy and interact with Sway smart contracts
- generate TypeScript types from Sway ABI JSON
- create and manage Fuel wallets from keys or mnemonics
- build and test a Fuel dApp with a local node
- craft and submit custom UTXO-based transactions

## When to choose
- you are building a frontend or Node.js dApp on the Fuel network
- you want end-to-end type safety between Sway contracts and TypeScript
- you need to deploy contracts or run a local Fuel node during development

## When to avoid
- you are targeting Ethereum or another non-Fuel blockchain
- you need a Rust or Go SDK for Fuel instead of TypeScript
- your project does not involve the Fuel ecosystem at all
