DRPC SDK

Client-side library for working with DRPC (drpc.org). It's responsibility to communicate with DRPC and also to check provided
signatures for response data, validating data authenticity. Supports node and browser.

Installation

npm install drpc-sdk

Example

``js
import { HTTPApi } from 'drpc-sdk';

async function getBlockHeight() {
let api = new HTTPApi({
api_key: 'api key',
url: 'https://drpc.org/api',
provider_ids: ['test'],
provider_num: 1,
});

// single request
let blockheight = await api.call({
method: 'eth_blockNumber',
params: [],
});

// batch request
let batch = await api.callMulti([
{
method: 'eth_blockNumber',
params: [],
},
{
method: 'eth_getBlockByNumber',
params: ['0x100001'],
},
]);
}

This module is written to work in node and browser. Because of that, by default webpack and other bundlers will try
to bundle node dependencies (like node-fetch, etc). However, if you use webpack you can just define constant and it will eliminate any
non-browser code.

`js
{
// ....
plugins: [
new webpack.DefinePlugin({
__isBrowser__: 'true',
}),
],
};
`

If you're using web3.js, drpc-sdk exposes the provider

`js
import { HttpDrpcProvider } from 'drpc-sdk/dist/esm/providers/web3';
// for cjs
// import { DrpcProvider } from 'drpc-sdk/dist/cjs/providers/web3';

async function getBlock(tag) {
let state = provider({
api_key: 'api key',
url: 'https://drpc.org/api',
provider_ids: ['test'],
provider_num: 1,
});
// or WsDrpcProvider for websockets
let provider = new HttpDrpcProvider(state);
let web3 = new Web3(provider);

let result = await web3.eth.getBlockNumber();
}
`

If you're using ethers.js, drpc-sdk exposes the provider

`js
import { DrpcProvider } from 'drpc-sdk/dist/esm/providers/ethers';
// for cjs
// import { DrpcProvider } from 'drpc-sdk/dist/cjs/providers/ethers';

async function getBlock(tag) {
let state = provider({
api_key: 'api key',
url: 'https://drpc.org/api',
provider_ids: ['test'],
provider_num: 1,
});
let provider = new DrpcProvider(state);
let block = await provider.getBlock(tag);
}
