Lodestar Eth Consensus API

This package is part of ChainSafe's Lodestar project

Typescript REST client for the Ethereum Consensus API spec

Usage

We use more typesafe approach for the API client, where all the errors are returned not thrown. This approach is more easy to document and better to handle all possible error cases.

import {getClient, HttpError} from "@lodestar/api";
import {config} from "@lodestar/config/default";

const api = getClient({baseUrl: "http://localhost:9596"}, {config});

api.beacon
  .getStateValidator(
    "head",
    "0x933ad9491b62059dd065b560d256d8957a8c402cc6e8d8ee7290ae11e8f7329267a8811c397529dac52ae1342ba58c95"
  )
  .then((res) => {
    if (res.ok) {
      console.log("Your balance is:", res.response.data.balance, res.ok, res.status);
    } else {
      console.error(res.status, res.error.code, res.error.message);
    }
  });
