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": [["DATA20", "QUANTITY|TAG"], "QUANTITY", 1, 2],
    ...
  },
  ...
}

Primitives:

• "DATA" : bytes data
• "DATA20" : bytes data, length 20
• "DATA32" : bytes data, length 32
• "Boolean" : boolean true or false
• "String" : string data
• "Array|DATA" : either an array of DATA or a single bytes DATA
• "QUANTITY" : a number quantity
• "QUANTITY|TAG" : a number quantity or a tag (e.g. 'latest', 'earliest' ...)

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": "DATA20",
      "to": "DATA20",
      "gas": "QUANTITY",
      "gasPrice": "QUANTITY",
      "value": "QUANTITY",
      "data": "DATA",
      "nonce": "QUANTITY"
    },
    ...
  }
  ...
}
