I've just published version 1.1.0 of my library, which is built to help developers who want to use SteemConnect on the Google Firebase platform. Let's discuss what has been added!
Quick links

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

Long-lived token support
steemconnect-firebase-functions main feature is making it easier to implement OAuth2 authorization code grant. This kind of OAuth2 flow has one big advantage - it enables app to require so called offline scope, which is used to obtain a refresh_token. The name of this token is quite describtive - it allows to refresh an access token. But why would we even do that?
It turns out that access_token expires after 7 days. With refresh_token, the app can get a new access_token instead of forcing user to login once again.
refreshAccessToken function
Version 1.1.0 of steemconnect-firebase-functions includes a brand new function used to exchange refresh_token for new access_token with SteemConnect.
Example usage:
import { refreshAccessToken } from 'steemconnect-firebase-functions';
const clientId = 'client-id';
const clientSecret = 'client-secret';
const refreshToken = 'refresh-token';
let newAccessToken;
refreshAccessToken(clientId, clientSecret, refreshToken).then(response => {
newAccessToken = response;
});
AccessTokenResponse interface
I believe that AccessToken interface name was confusing because interface had access_token property, so I decided to rename interface name to AccessTokenResponse. I have also added an optional refresh_token property.
The interface now has the following code:
export interface AccessTokenResponse {
access_token: string;
expires_in: number;
username: string;
refresh_token?: string;
}
Broadcasting more types of operations to the Steem blockchain
Until version 1.1.0 the steemconnect-firebase-functions library had only one function that allowed to broadcast operations to the Steem blockchain - broadcastOperations.
Although that was enough to do broadcast literally anything, I've added some functions that support the most frequently used operations - upvote, post, and comment. I hope it will be useful for the developers!
broadcastPost function
As the name suggests, you can use this function to broadcast a post to the Steem blockchain.
Example usage:
import { broadcastPost } from 'steemconnect-firebase-functions';
const accessToken = 'access-token';
const mainTag = 'test-tag';
const postAuthor = 'jakipatryk';
const postPermlink = 'test-post-432rhbb23';
const postTitle = 'Test post';
const postBody = 'This is a test post content';
broadcastPost(
accessToken,
mainTag,
postAuthor,
postPermlink,
postTitle,
postBody
).then(response => {
console.log(response);
});
broadcastPostWithBeneficiaries function
Works almost the same as the broadcastPost function, but in addition, enables to set up beneficiaries - an account which will get a part of the rewards of broadcasted post.
Example usage:
import { broadcastPostWithBeneficiaries } from 'steemconnect-firebase-functions';
const accessToken = 'access-token';
const mainTag = 'test-tag';
const postAuthor = 'jakipatryk';
const postPermlink = 'test-post-432rhbb23';
const postTitle = 'Test post';
const postBody = 'This is a test post content';
const beneficiariesAccount = 'utopian.pay';
const beneficiariesWeight = 2500; // 25%
broadcastPostWithBeneficiaries(
accessToken,
mainTag,
postAuthor,
postPermlink,
postTitle,
postBody,
beneficiariesAccount,
beneficiariesWeight
).then(response => {
console.log(response);
});
broadcastComment function
Broadcasts a comment to given post/other comment.
Example usage:
import { broadcastComment } from 'steemconnect-firebase-functions';
const accessToken = 'access-token';
const parentAuthor = 'ned';
const parentPermlink = 'steemfest2-closing-dinner';
const commentAuthor = 'jakipatryk';
const commentPermlink = 'f34fre5';
const commentBody = 'This is a test comment';
broadcastComment(
accessToken,
parentAuthor,
parentPermlink,
commentAuthor,
commentPermlink,
commentBody
).then(response => {
console.log(response);
});
broadcastUpvote function
Broadcasts an upvote.
Example usage:
import { broadcastUpvote } from 'steemconnect-firebase-functions';
const accessToken = 'access-token';
const voter = 'jakipatryk';
const author = 'ned';
const permlink = 'steemfest2-closing-dinner';
const weight = 10000; // 100%
broadcastUpvote(accessToken, voter, author, permlink, weight).then(response => {
console.log(response);
});
What next?
The current documentation is... bad. That's what I will be working on now.
