ethjs-schema


The complete Ethereum RPC specification as a JSON object export.

Install

npm install --save ethjs-schema

Usage

const schema = require('ethjs-schema');

console.log(schema.tags);

// result ['latest', 'earliest', ...]

About

This is a pure JSON export of the Ethereum RPC specification. This can be, and is being used to generate the ethjs-query object. This object specification is not standardized, it is the leanest data structure implementation I could come up with for the Ethereum RPC spec.

The entire spec is contained in the schema.json file.

Specification Details

Method Specification:

methods: {
  <method name : [ input(s), output(s), minimum required outputs, 'latest' tag default position (if any) ] >,
}

example:

{
  methods: {
    "eth_getBalance": [["D20", "Q|T"], "Q", 1, 2],
    ...
  },
  ...
}

Primitives:

  • "D" : bytes data
  • "D20" : bytes data, length 20
  • "D32" : bytes data, length 32
  • "B" : boolean true or false
  • "S" : string data
  • "Array|DATA" : either an array of DATA or a single bytes DATA
  • "Q" : a number quantity
  • "QP" : a number quantity (with frontal padding)
  • "Q|T" : a number quantity or a tag (e.g. 'latest', 'earliest' ...)

Note, post version 0.1.1 value primitives have been compressed.

Tags:

{
  "tags": ["latest", "earliest", "pending"],
}

Complex Data Structures (.objects):

The __required property is added to specify which properties of the object must be fulfilled in order to be a valid object structure (ready for payload transmission).

  • "EthSyncing"
  • "SendTransaction"
  • "EstimateTransaction"
  • "CallTransaction"
  • "Block"
  • "Transaction"
  • "Receipt"
  • "Filter"
  • "FilterChange"
  • "SHHPost"
  • 'SHHFilter'
  • "SHHFilterChange"
  • "SHHMessage"

example:

{
  "objects": {
    "SendTransaction": {
      "__required": ["from", "data"],
      "from": "D20",
      "to": "D20",
      "gas": "Q",
      "gasPrice": "Q",
      "value": "Q",
      "data": "D",
      "nonce": "Q"
    },
    ...
  }
  ...
}

Help out

There is always a lot of work to do, and will have many rules to maintain. So please help out in any way that you can:

  • Create, enhance, and debug ethjs rules (see our guide to "Working on rules").
  • Improve documentation.
  • Chime in on any open issue or pull request.
  • Open new issues about your ideas for making ethjs-schema better, and pull requests to show us how your idea works.
  • Add new tests to absolutely anything.
  • Spread the word.

Please consult our Code of Conduct docs before helping out.

We communicate via issues and pull requests.
