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.\n\nEthObjects hold Ethereum bare bones data with lots of helper functions for viewing and moving them in and out of other popular formats.\n\n```\nnpm install eth-object\n```\n\nThe following objects are supported:\n\n```javascript\nconst { Account, Header, Log, Proof, Receipt, Transaction } = require('eth-object')\n```\n\n## Formating\n\nThe data formats used/returned for account, `header`, `log`, `proof`, `receipt`, and `transaction` are `eth-object`s. 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.\n\nAn account, for example, will look like this:\n\n```javascript\n// [\n// ,\n// ,\n// ,\n// ,\n// ]\n```\n\nIts a 4-item array of _bytearrays_ representing the _nonce, balance, storageRoot, and codeHash_ respectively. \n\nBut they not just simple arrays that do this:\n\n```javascript\nconsole.log(account[0]) // => \n```\n\nThey also have helper methods for:\n\n- The object's named fields property:\n\n```javascript\nconsole.log(account.nonce) // => \n```\n\n- Conversion to printable formats\n\n```javascript\nconsole.log(account.toJson())\n// {\n// \"nonce\":\"0x01\",\n// \"balance\":\"0x\",\n// \"storageRoot\":\"0xc14953a64f69632619636fbdf327e883436b9fd1b1025220e50fb70ab7d2e2a8\",\n// \"codeHash\":\"0xf7cf6232b8d655b92268b3565325e8897f2f82d65a4eaaf4e78fcef04e8fee6a\"\n// }\n```\n\n- Conversion to the native bytes:\n\n```javascript\nconsole.log(account.buffer) // native format (used to calculate hashes and roots)\n// \n```\n\n- A text-pastable version of the bytes\n\n```javascript\nconsole.log(account.hex) // rlp encoded bytes as a hex string\n// \"0xf8440180a0c14953a64f69632619636fbdf327e883436b9fd1b1025220e50fb70ab7d2e2a8a0f7cf6232b8d655b92268b3565325e8897f2f82d65a4eaaf4e78fcef04e8fee6a\"\n```\n\nAnd they can be created from a direct RPC result or any other format that you may find yourself with:\n\n```javascript\nAccount.fromRpc(rpcResult)\nAccount.fromHex(hexString)\nAccount.fromBuffer(Bytes)\nAccount.fromRaw(nativeArray)\n```\n\n","readmeFilename":"README.md"}
