Steemit Post Comment Using Nodejs
In this tutorial, you will learn to use steemjs to post a comment to steemit.com.
Prerequisites
- Basic knowledge in nodejs
The data is fetched as JSON from URL and then it is sent to the steemit. We will be using the following dependencies
- Steem
- HTTP
You can install these by the following command
npm install steem --save
npm install http --save
First, we need to create two variable for steem and http
var steem = require('steem');
var http = require('http');Next, We will create a server and listen to a port. You can use any other port.
http.createServer(function (req, res) {
}).listen(2001);The next part is to fetch the data that we want to post. You need to add your username, posting key from steemit(Wallet -> Permission->Show Private Key)
http.get('http://yourwebsite.com/api/steemit.json',function(res){
var body = '';
res.on('data',function(chunk){
body += chunk;
});
res.on('end',function(){
var post = JSON.parse(body);
steem.broadcast.comment(
'POSTING_PRIVATE_KEY', // your steemit posting private key
'',
post.category,
'YOUR_STEEMIT_USERNAME', // your username
post.slug, // Your Steemit post slug
post.title,
post.message,
{ tags: [ post.tags ] },
function(err, result) {
console.log(err, result);
$('#message').text(err);
$('#ms').text(result.id);
});
})
});
Example of JSON file that we fetch from URL
{
title: "Your Post Title",
message: "Your message contents goes here. You can add image url too.",
tag: ""general" ",
category: "programming",
slug: "your-post-title"
}Full Source Code:
After uploading the file to your server you need to run node file.js or forever start file.js
