Full, runnable src of Blog Feed can be downloaded as part of: tutorials/javascript (or download just this tutorial:

This tutorial pulls a list of the most recent five user’s posts from the blockchain and displays them in simple list. Also some notes about usage of client.database.getDiscussions API.


Tutorial is demonstrates the typical process of fetching account blog posts. It is quite useful if you want to embedd your blog posts on your website these tutorial will help you achieve that goal as well. This tutorial will explain and show you how to access the Hive blockchain using the @hiveio/dhive library to build a basic blog list of posts filtered by a tag

  1. Configure connection Configuration of dhive to use proper connection and network
  2. Query format Simple query format to help use fetch data
  3. Fetch data and format Fetch data and display in proper interface

1. Configure connection

In order to connect to the live Hive network, all we have to do is provide connection url to a server that runs on the network. dhive by default set up to use live network but it has flexibility to adjust connection to any other testnet or custom networks, more on that in future tutorials.

In first couple lines we require package and define connection server:

const { Client } = require("@hiveio/dhive");

const client = new Client('');

2. Query format

var query = {
    tag: 'hiveio', // This tag is used to filter the results by a specific post tag
    limit: 5, // This limit allows us to limit the overall results returned to 5

3. Fetch data and format

client.database.getDiscussions function is used for fetching discussions or posts. The first argument to this function determines which equivalent of the appbase condenser_api.get_discussions_by_* api calls it’s going to use. Below is example of query and keyword ‘blog’ indicates condenser_api.get_discussions_by_blog and somewhat counter-intuitively query.tag indicates the account from which we want to get posts.

    .getDiscussions('blog', query)
    .then(result => {
        var posts = [];
        result.forEach(post => {
            const json = JSON.parse(post.json_metadata);
            const image = json.image ? json.image[0] : '';
            const title = post.title;
            const author =;
            const created = new Date(post.created).toDateString();
                `<div class="list-group-item"><h4 class="list-group-item-heading">${title}</h4><p>by ${author}</p><center><img src="${image}" class="img-responsive center-block" style="max-width: 450px"/></center><p class="list-group-item-text text-right text-nowrap">${created}</p></div>`

        document.getElementById('postList').innerHTML = posts.join('');
    .catch(err => {
        alert('Error occured' + err);

The result returned form the service is a JSON object with the following properties:

From this result we have access to everything associated to the post including additional metadata which is a JSON string that must be decoded to use. This JSON object has additional information and properties for the post including a reference to the image uploaded. And we are displaying this data in meaningful user interface. Note: it is truncated to one element, but you would get five posts in array
