web3.js as a Svelte store.

Installation

npm i svelte-web3

Basic Usage

Import the ethereum main helper and needed derived Svelte stores (see list below):

import { ethereum, web3, selectedAccount, isListening } from 'svelte-ethereum';

To enable connection to the current window provider:

ethereum.setBrowserProvider()

If connection is successful, you can access the instantiated web3.js with the current window provider using the $ svelte store syntax :

$web3.eth.getBalance(<Ethereum address>)

Derived stores

• chainId: The current blokchain Id.
• chainName: Name of the The current blokchain.
• isListening: true if connection to the provider was successful.
• selectedAccount: current selected account.

Svelte stores are automatically updated when network or selected account change.

Please see the file example/App.svelte for more usage information.
