EOSIO MongoDB Queries

Quickly and easily create complex MongoDB Queries for the EOSIO blockchain.

Install

npm

$ yarn add eosio-mongodb-queries

web

<script src="https://wzrd.in/standalone/eosio-mongodb-queries@latest"></script>

Quickstart

import { MongoClient } from "mongodb";
import { getAccount } from "eosio-mongodb-queries";

(async () => {
    const client = await MongoClient.connect("mongodb://localhost:27017", { useNewUrlParser: true });

    // Optional Parameters
    const options = {
        gte_block_num: 0,
        lte_block_num: Infinity,
    };
    const result = await getAccount(client, "eosnationftw", options);
    // {
    //   name: 'eosnationftw',
    //   block_num: 6101090,
    //   stake_quantity: 2.8,
    //   stake_net_quantity: 0.4,
    //   stake_cpu_quantity: 2.4
    // }
})();

EOSIO Full Node

You must first enable the MongoDB plugin to your EOSIO full node by including the following to your configuration.

config.in

# Override default maximum ABI serialization time allowed in ms (eosio::chain_plugin)
abi-serializer-max-time-ms = 5000

# Plugin(s) to enable, may be specified multiple times
plugin = eosio::mongo_db_plugin

# MongoDB URI connection string, see: https://docs.mongodb.com/master/reference/connection-string/. If not specified then plugin is disabled. Default database 'EOS' is used if not specified in URI. Example: mongodb://127.0.0.1:27017/EOS (eosio::mongo_db_plugin)
mongodb-uri = mongodb://localhost:27017

Replay Blocks

To allow actions to be decoded from the ABI, you must replay all blocks from the genesis.

$ nodeos --replay-blockchain --hard-replay-blockchain --mongodb-wipe

  • options.name (string | Array<string>)? Filter by action names (eg: "undelegatebw", "delegatebw")
  • options.limit number Limit the maximum amount of of actions returned (optional, default 25)
  • options.skip number? Skips number of documents
  • options.sort object? Sort by ascending order (1) or descending order (-1) (eg: {block_num: -1})
  • options.match object? Match by entries using MongoDB's $match (eg: {"data.from": "eosio"})
  • options.trx_id string? Filter by exact Transaction Id
  • options.irreversible boolean? Irreversible transaction (eg: true/false)
  • options.block_num number? Filter by exact Reference Block Number
