How to initialize dhive client?

• I've created a separate file named dhive_client.js file
• Content of it are as follows.
• I've added multiple API endpoints.

var dhive = require("@hiveio/dhive");
var client = new dhive.Client([
  "https://api.hive.blog",
  "https://api.deathwing.me",
  "https://hive-api.arcange.eu",
  "https://hived.emre.sh",
  "https://api.openhive.network",
  "https://rpc.ausbit.dev",
  "https://rpc.mahdiyari.info",
  "https://hive-api.3speak.tv",
  "https://techcoderx.com",
]);

module.exports = {
  client,
};

How to fetch notifications of an account using dhive library?

• I would recommend creating a separate file
• I created get_notifications.js file
• Here are the content for it.
• NOTE: I tried sending limit above 100 & it failed.
• So, limit must not exceed 100.

async function getNotifications(client, account) {
  try {
    let data = await client.call("bridge", "account_notifications", {
      account: account, //"sagarkothari88",
      limit: 100,
    });
    return data;
  } catch (e) {
    return false;
  }
}

module.exports = {
  getNotifications,
};

• With above function in place, now you can easily getNotifications for any account.
• Note that, I've used sagarkothari88 as account name.
• You can use any account name / hive user.
• It must not include @ sign.
• If there is some error getting notifications, above function will simply return false.

const { client } = require("./dhive_client");
const { getNotifications } = require("./helper/get_notifications");

async function mainFunction() {
  const account = "sagarkothari88";
  const data = await getNotifications(client, account);
  console.log(`Notifications data - ${JSON.stringify(data)}`);
}

mainFunction();
