ethblockart-humanizer v1.0.6

Transforms Ethereum block's metadata

to a humanized view.

Transaction Types

• erc20, nft, transfer, unrecognized

Transaction Value, Gas

• average, minimum, maximum, median, summ value/gas in transactions array

Block Season

• winter, sprint, summer, autumn

Daytime

• night, morning, day, afterday, evening in UTC

This package uses block data structure via EthBlock.Art.

If you want to use this package outside of EthBlock.Art development boilerplate, you need to be sure if the block data structure from your API are prepared to this package structure based on useDApp's (and EthBlock.Art) block metadata response.

Different APIs are gives different 'block metadata'.

For example, web3 node module has input instead of data property in transactions array item.

Install & Use

npm i ethblockart-humanizer

import { getBlockHumanized } from 'ethblockart-humanizer';

// ...
const humanizedBlock = getBlockHumanized(block);
// ...
