@polkadot/api

Warning - currently this does not actually do all that much, it is an attempt to put into code some thoughts about how to maintain the endpoints. This library provides a clean wrapper around all the methods exposed by a Polkadot network client. Methods are auto-generated for the JsonRPC interface definitions.

Usage

Installation -

npm install --save @polkadot/api

Initialisation -

import Api from '@polkadot/api';
import HttpProvider from '@polkadot/api-provider/http';

const provider = new HttpProvider('http://127.0.0.1:9933');
const api = new Api(provider);

Making calls -

api.chain
  .getHeader('0x1234567890')
  .then((header) => console.log(header))
  .catch((error) => console.error(error));

Available methods
