Svelte-Web3-Connect

small set of tools used to easily connect an injected wallet (Metamask, Tally Oh!, Coinbase), when creating a web3 wesbite with svelte.

What?

This small library exports a few functions and stores that can be used in your svelte application

Requirements

1. svelte is added as a peer dependency (it must be installed in your project).
2. It works with ethers.js and expects it to be passed in the init() function

functions

init(ethers, shouldConnectAccount)

Initialize the providers and tries to reach the current injected wallet. If the user has already connected to the current website in the past, it will try to call connectAccount() too.

connectAccount()

Asks the current connected wallet to connect the account.

Requires init() to be called prior

disconnect()

Disconnects the current account

connectWithGivenProvider(ethereumProvider, ethersProvider)

Allows consumer to st Ethereum Provider and EthersProvider externally without relying on the injected wallet.

changeChainFor(chainId)

Asks the current wallet to switch the current network to network corresponding to chainId

stores

hasWallet

true if there is a provider known.

ethereumProvider

the current ethereum provider; by default the injected wallet, else the wallet provided when calling connectWithGivenProvider()

provider

the current ethers provider

chainId

the current chain id

signer

the current signer (if connectAccount has been called)

signerAddress

the current signerAddress (if connectAccount has been called)

connected

stores value getters

getChainId()

gets the value of current chainId store

getSigner()

getProvider()

getSignerOrProvider()

gets the value of current signer or provider stores

getEthereumProvider()
