DAPI Client

Client library used to access Xazab DAPI endpoints

This library enables HTTP-based interaction with the Xazab blockchain and Xazab Platform via the decentralized API (DAPI) hosted on Xazab masternodes.

DAPI-Client provides automatic server (masternode) discovery using either a default seed node or a user-supplied one
DAPI-Client maps to DAPI's RPC and gRPC endpoints

Install

npm install @xazab/js-dapi-client

Usage

Basic

const DAPIClient = require('@xazab/dapi-client');
const client = new DAPIClient();

client.core.getStatus().then((coreStatus) => {
  console.dir(coreStatus);
});

Custom seed node

Custom seed nodes are necessary for connecting the client to devnets since the client library is unaware of them otherwise.

const DAPIClient = require('@xazab/dapi-client');

var client = new DAPIClient({
  seeds: [{
     host: 'seed-1.evonet.networks.xazab.xyz',
     httpPort: 3000,
     grpcPort: 3010,
  }],
});

client.core.getBestBlockHash().then((r) => {
  console.log(r);
});

Note: The seed node shown above (seed-1.evonet.networks.xazab.xyz) is for the Xazab Evonet testing network.

Custom addresses

Custom addresses may be directly specified in cases where it is beneficial to know exactly what node(s) are being accessed (e.g. debugging, local development, etc.).

const DAPIClient = require('@xazab/dapi-client');

var client = new DAPIClient({
  dapiAddresses: [
    '127.0.0.1:3000:3010',
    '127.0.0.2:3000:3010',
  ],
});

client.core.getBestBlockHash().then((r) => {
  console.log(r);
});

Command specific options

DAPI Client options can be passed directly to any command to override any predefined client options and modify the client's behavior for that specific call.

const DAPIClient = require('@xazab/dapi-client');

// Set options to direct the request to a specific address and disable retries
const options = {
  dapiAddresses: ['127.0.0.1'],
  retries: 0,
};

client.core.getBestBlockHash(options).then((r) => {
  console.log(r);
});
