[steemconnect-firebase-functions] Version 1.2: state, createFirebaseAccount, and broadcasts

Development of steemconnect-firebase-functions doesn't stop, because I want to use it in the project I am going to start coding soon. Version 1.2 has just been released!

Quick Recap

steemconnect-firebase-functions is a library designed to help developers who want to create apps based on SteemConnect and Firebase. The library makes it easy to:

• implement OAuth2 Authorization Code Grant (enables user to log in to your app using SteemConnect)
• broadcast operations to Steem blockchain (post, comment, upvote, etc.)
• make operations on the Firebase products (Authentication, Firestore)

• NPM: https://www.npmjs.com/package/steemconnect-firebase-functions

New Features

Version 1.2.0 comes with a few new features. As I mentioned in the introduction, I am going to create a new project based on SteemConnect and Firebase, so I had to add them.

State

I have enabled to use so-called state variable in the SteemConnect authorization URL by adding optional parameter state in the getAuthorizationUrl function. This parameter can be used for example to prevent cross-site request forgery attacks.

PULL REQUEST

createFirebaseAccount

I found it useful to add additional user data to the user profile, so they would become available on the auth object on the frontend. What kind of additional data am I talking about? Most important are username and photoURL (for example avatar).

I added createFirebaseAccount function that either creates an Firebase auth account or updates it if one already exists.

Example usage:

import { createFirebaseAccount } from 'steemconnect-firebase-functions';

import * as admin from 'firebase-admin';

const serviceAccount = require('../serviceAccountKey.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount)
});

const uid = 'steemconnect:jakipatryk';
const username = 'jakipatryk';
const photoURL = 'https://some-uri.image/avatar';

createFirebaseAccount(admin, uid, username, photoURL).then(() => {
  console.log(5 * 20 + 11);
});

See how I implemented it: COMMIT.

broadcastFollow

This version of steemconnect-firebase-functions also comes with new broadcast functions. First one simply broadcasts a follow to the blockchain.

Example usage:

import { broadcastFollow } from 'steemconnect-firebase-functions';

const accessToken = 'access-token';
const username = 'jakipatryk';
const userToFollow = 'ned';

broadcastFollow(accessToken, username, userToFollow).then(result => {
  console.log(result);
});

See how I implemented it: COMMIT

broadcastUnfollow

So we can broadcast follow, it would be great if we could also broadcast unfollow. Yep, you are right.

Example usage:

import { broadcastUnfollow } from 'steemconnect-firebase-functions';

const accessToken = 'access-token';
const username = 'jakipatryk';
const userToUnfollow = 'ned';

broadcastUnfollow(accessToken, username, userToUnfollow).then(result => {
  console.log(result);
});

See how I implemented it: COMMIT.

broadcastReblog

This one was actually kinda funny. Did you know that operation id of the reblog is... follow? I also didn't know, but it just works like that.

Example usage:

import { broadcastReblog } from 'steemconnect-firebase-functions';

const accessToken = 'access-token';
const username = 'jakipatryk-dev';
const postAuthor = 'jakipatryk';
const postPermlink =
  'steemconnect-firebase-functions-version-1-1-0-has-just-been-published';

broadcastReblog(accessToken, username, postAuthor, postPermlink).then(
  result => {
    console.log(result);
  }
);

See how I implemented it: COMMIT.

Summary

Version 1.2.0 of steemconnect-firebase-functions introduces a few new features, such as optional state variable in the SteemConnect authorization URL, createFirebaseAccount function to create Firebase auth account with user details, broadcastFollow, broadcastUnfollow, and broadcastReblog functions.

A new version might be released if I decide that I need some additional functionality during coding my new project, which is not public yet... Stay tuned ;)
