Web3

Thanks to ntrotner and thanks to the hints we have received in the context of this issue, Deno is ready for web3 with this module.

With this module you can connect your TypeScript in Deno program with the Ethereum Blockchain.

If you need to use nodejs instead of deno, check the web3 npm library. Some of you might also use the ethers library as an alternative.

In some months from now (writing this early 2022) it might be possible to just import such dependencies via skypack.dev.

Usage Example

Get Balance

deno run --allow-net https://deno.land/x/web3/usage-examples/get-balance.ts https://mainnet.infura.io/v3/<your-project-id>

import Web3 from 'https://deno.land/x/web3/mod.ts'

const providerURL = Deno.args[0]

const web3 = new Web3(new Web3.providers.HttpProvider(providerURL))

const balance = await web3.eth.getBalance("0x7a915e362353d72570dcf90aa5baa1c5b341c7aa")

console.log(`the balance is ${balance} wei`)

Get Transaction

deno run --allow-net https://deno.land/x/web3/usage-examples/get-transaction.ts https://mainnet.infura.io/v3/<your-project-id>

import Web3 from 'https://deno.land/x/web3/mod.ts'

const providerURL = Deno.args[0]

const web3 = new Web3(new Web3.providers.HttpProvider(providerURL))

const transactionHash = "0x0d558d490c89fc94ddfebd284e39da5c1bcff15d18c4e9fd2eb37a202d20c703"

const transaction = (await web3.eth.getTransaction(transactionHash))

console.log(transaction)

Create Account

deno run --allow-net https://deno.land/x/web3/usage-examples/create-account.ts https://mainnet.infura.io/v3/<your-project-id>

import Web3 from 'https://deno.land/x/web3/mod.ts'

const providerURL = Deno.args[0]

const web3 = new Web3(new Web3.providers.HttpProvider(providerURL))

const newAccount = await web3.eth.accounts.create()

console.log(newAccount)
