Polkadot JavaScript API

Introduction

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.

Installation -

npm install --save @polkadot/api

Initialisation -

import Api from '@polkadot/api';

const provider = new Api.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));
