Summary
Small, simple library to get non-empty blocks/transactions.
It simply takes an instance of web3
, an array of contract jsons for ABI injection and an optional middleware to modify TXs before being added.
Taken from Ed's blocks library in KLM.
Usage
Example Route:
Note: In my example, web3 and contract json's are injected via eth
const { BlockExplorer } = require('@appliedblockchain/simple-block-explorer')
const web3 = new Web3()
const componentJson = require('contracts/Components.json')
const contracts = [ componentJson ]
const txMiddleware = async (tx) => {
tx.value = Number(tx.value)
tx.extraProperty = 'testing'
return tx
}
const handler = async (ctx) => {
const blockExplorer = new BlockExplorer({
web3,
contracts,
txMiddleware
})
ctx.body = await blockExplorer.getTransactions()
}
