EthObject

Trying to serialize Ethereum Trie / LevelDB data from hex, buffers and rpc into the same format is tough. This library aims to solve that with re-usable and composable objects that you can just call Object.from to ingest new data.

EthObjects hold Ethereum bare bones data with lots of helper functions for viewing and moving them in and out of other popular formats.

``
npm install eth-object
`

The following objects are supported:

`javascript
const { Account, Header, Log, Proof, Receipt, Transaction } = require('eth-object')
`

Formating

The data formats used/returned for account, header, log, proof, receipt, and transaction are eth-objects. They mimic the native Ethereum format of being _arrays of byteArrays and nested arrays (of the same)_. This is the format you would find in the native database after being rlp-decoded.

An account, for example, will look like this:

`javascript
// [
// ,
// ,
// ,
// ,
// ]
`

Its a 4-item array of _bytearrays_ representing the _nonce, balance, storageRoot, and codeHash_ respectively.

But they not just simple arrays that do this:

`javascript
console.log(account[0]) // =>
`

They also have helper methods for:

- The object's named fields property:

`javascript
console.log(account.nonce) // =>
`

- Conversion to printable formats

`javascript
console.log(account.toJson())
// {
// "nonce":"0x01",
// "balance":"0x",
// "storageRoot":"0xc14953a64f69632619636fbdf327e883436b9fd1b1025220e50fb70ab7d2e2a8",
// "codeHash":"0xf7cf6232b8d655b92268b3565325e8897f2f82d65a4eaaf4e78fcef04e8fee6a"
// }
`

- Conversion to the native bytes:

`javascript
console.log(account.buffer) // native format (used to calculate hashes and roots)
//
`

- A text-pastable version of the bytes

`javascript
console.log(account.hex) // rlp encoded bytes as a hex string
// "0xf8440180a0c14953a64f69632619636fbdf327e883436b9fd1b1025220e50fb70ab7d2e2a8a0f7cf6232b8d655b92268b3565325e8897f2f82d65a4eaaf4e78fcef04e8fee6a"
`

And they can be created from a direct RPC result or any other format that you may find yourself with:

`javascript
Account.fromRpc(rpcResult)
Account.fromHex(hexString)
Account.fromBuffer(Bytes)
Account.fromRaw(nativeArray)
