STEEM and STEEM Dollar Donations For Livestreamer - with

in utopian-io •  last year

Hey folks! In todays post I'm going to introduce - A new platform for livestreamer who wants to accept STEEM donations during their streams.

SteemAlerts uses streamlabs to display donation alerts and steemconnect for the authentification. The complete project is a nodeJS expressjs app.

router.get('/steem', function(req, res) {
    if (!req.query.access_token) { //if the url query has no access token redirect the user to steemconnect
    } else {
        steem.setAccessToken(req.query.access_token); // set the access token, response) { //request the users steem profile
            response.account.json_metadata = JSON.parse(response.account.json_metadata);
            req.session.steem = {           //and store it in the session
                security_context: {
                    access_token: req.query.access_token
                user: response
            res.redirect("/")       //now redirect the user back to the landingpage

After the users logged in with StreamLabs and Steem he can proceed to his Dashboard:

The dasboard consinsts of a small template with a huge amount of javascript code to keep all the informations up to date.
To start SteemAlerts the user has to click the red status message in the menu:

As soon as he click the button an ajax request to /api/donations/add/1 is started:

Now I retreive the account history for the user:
steemAPI.api.getAccountHistory(, -1, 1000, function (err, result)
and iterate throught all transaction of type "transfer". To avoid that power up transactions are shown I check that the "from" field is different to the current user. In the first request I add all new transactions to the database and set them to hidden.
database.addTX(ele[1].trx_id, JSON.stringify(ele), ele[1].op[1].to, parseFloat(ele[1].op[1].amount), "STEEM", hidden);

Hidden means that they dont appear in the dashboard. No SteemAlerts continuously checks for new incoming transfers of STEEM and STEEM Dollar. As soon as a new transfers was found a SteemAlert calculates the value of the sent STEEM into USD. (Streamlabs only support fiat currencies).

This is how the alert is sent. ele is the transaction and price is the current price for STEEM in USD. The message is built using the transaction as well and always looks like:
@{username} sent you {amount} {currency} If the user set a memo to the transaction the message is extended with: with the message: {memo}

    name: ele[1].op[1].from,
    identifier: ele[1].op[1].from,
    amount: parseFloat(ele[1].op[1].amount) * price,
    currency: 'USD',
    message: message
    }).catch(function (e) {

Here is an example of a SteemAlerts donation:

As you can see the amount of Steem is beneath the amount of USD so you will be able to keep track of your STEEM donations. Additionally the dashboard will update with the new total amount of donated STEEM and will display the donation with some details in the table.

The live site is available at and is currently in a closed beta phase. If you're interested in SteemAlerts and want to participate find me on the utopian discord and write me a direct message. Join my Discord:
