Update your STEEM apps! Big changes coming for 3rd party developers

in #steemitdev4 years ago (edited)

We have created a new public jussi endpoint for third party applications to use. Jussi is our custom built caching layer, for use with steemd and other various services (such as SBDS). The jussi endpoint is available now at https://api.steemit.com. Condenser (the front-end application for steemit.com) is already using api.steemit.com today. We encourage all third party developers to begin using the new endpoint right away. We are planning to deprecate the steemd.steemit.com endpoint in favor of api.steemit.com in the near future.

What does this mean for third party developers?

For our public steemd endpoint using api.steemit.com, apps will need to speak to it through http/jsonrpc instead of websockets. The libraries we maintain will soon be updated to default to api.steemit.com instead of steemd.steemit.com, which will cover a lot of apps that don't set an endpoint and just use the default.

JSONRPC has been chosen to be used for all of our infrastructure for a variety of reasons; the two biggest being the ability to more easily load balance and manage connections, and the ease of use for new developers - as JSONRPC is much more common than websockets.

Is it going to be difficult to update my steem apps?

In most cases it will be extremely easy to make this change. The four most popular steem libraries (steem-js, steem-python, radiator, and dsteem) that the majority of steem apps are built with already support http/jsonrpc. Other libraries may as well. All you'll need to do is update the endpoint/url to https://api.steemit.com from the older wss://steemd.steemit.com. If you have a custom written app that doesn't use one of the popular libraries you will need to change your transport method to http/jsonrpc from websockets.

How long do I have?

The timeframe for deprecating steemd.steemit.com is not determined yet, but you should start implementing this change as soon as possible if you are using our public nodes for your STEEM apps. We will announce a final date before the endpoint is taken away.


I'm a user..not a geek
I have no idea what this means.
That said..I REALLY APPRECIATE the update.
It makes me feel a LOT better knowing that the devs
and are working on Steemit.
similar updates during the last few weeks when Steemit was broke.

I put an oar in here ,since we are in the same boat.

Basically, for end users, you can expect steemit.com and all steem-based tools to become more stable and more responsive.

Two imperfect metaphors that describe what happened in two levels of detail:

  1. You ever gone to an office to talk with a super expert about something, but they are too busy. But, it turns out that their assistant was helpful and solved your problems without you having to wait around.

  2. Whenever you want to work on Steem, you go down to the steem office. There's this one really smart giant, but kinda grumpy robot who takes your request and goes to work magic on the blockchain then gets back to you. They tried making his brain bigger and giving Botty tons of coffee to get him to work faster. They even tried giving him more arms. Still Botty got way too busy and developed a bit of a temper. It's pretty hard to build more like Botty because he's fat, has a ton of custom parts and fills up the building. He also slurps down the electricity and takes ages to wake up if he goes to sleep.
    But, it turns out that most of what botty does is read stuff from steem. And, there's some bots made from high quality mass produced parts that are way less fat, slurp less power and wake up super quick when summoned. These bots are super good at handling your steem requests and remembering what they read just in case you or the next customer needs it. They don't like to bother Botty unless they need too. These guys are called Jussi.
    So now, you when you go to steem office you talk with any of the available Jussi bots. If you're just asking to read something, chances are your Jussi bot can pull it from their memory. When Jussi can't remember something or they need to write something into the blockchain (like upvotes, postings etc) then they go ask Botty and get back to you at super fast bot speeds.
    When the steem office gets really busy, it's super easy to open up more counters and have more Jussi bots ready to serve - afterall Jussi bots are made from cheap mass produced but high quality parts. When steem gets less busy then some Jussi counters can be closed to save power.

That's kinda what happened.

I'm going to turn this into a post.

That explains everything.
Thank you.

Like Everitt, I'm an end user, not a developer.
My IT experience is in usability and human factors (aka "developers' most hated person"), not code.
I'm also PR and communications.
I just want things to WORK... and when they don't, I want someone to wave a flag and say "Yeah, shit's broken right now, but we're fixing it..."
Silence when shit breaks is a bad deal. People lose confidence.
So THANK YOU for the update.

These more frequent updates are great. Please keep them coming & thanks for all your hard work.

But got some bugs. I updated one of the server that runs on Yehey.org Load Balancer servers to use https://api.steemit.com as suggested instead of wss://steemd.steemit.com. Getting this error.

Everything is working fine but when I start in the homepage, click on new or hot I have to reload/refresh the screen to see the posts. Then go back to homepage, it also require to refresh. This behavior is only happening when using https://api.steemit.com.

I will also post this findings in github.com.
Thank you for your hard work.

Excellent! Thank you so much for keeping us informed on what's being done to improve the performance of this site we love so much. I'm already starting to see improvements. Things are actually working as expected again!


I like to read the dev blog to keep up to date, although it’s in very general terms since most of this goes over my head... But...
Whatever is going on, to me, Steemit seems much more stable and responsive this evening. And as they say in the tech world, “The proof is in the pudding.” (Just kidding. No one says that in the tech industry, or anywhere else probably... but if I hit “post” and this comment sails right through I’m going to celebrate with some pudding...)

I hope you have plenty of pudding.

"The proof is in the pudding", I'll remember that.

Ahem: "the proof of the pudding is in the eating."

Shortening it the way people have, it sounds like "look for the engagement ring or other prize, it's inside the pudding!" :)

Thanks for the updates. Good to know that devs are working to make the application better!

Does this mean things will be less glitchy?
Be nice to here from the Dev's when the site is having problems...
Why can't the dev's do something like what the extensions for firefox/crome [email protected]? and implement some way of getting rid of dead followers,and hiding resteems or sort them like Busy.org ? why all the cool things coming from add on's...
Be nicer if things were more unified rather than having to switch things through second? party...app,ext,page.
I am not a tech,so Idk.
Thank You for the great site! I do understand it is still beta stage,I can't wait to see how this grows and expands!

Great, even more apps are coming soon.. wish I could have an online training how to use this..

Very good news. I can imagine a scenario where 3rd party developers utilize the new api to bring a number of innovative personal and business services to market. This will in turn help to broaden the appeal of Steem blockchain technology.

It's obvious now that your team is working tirelessly to make steemit, steem as better as steemians has dreamed @steemitdev

jussi is another great added value as it's name was derived from juicy.

It's a cool custom built caching layer.

The guy who made it, @layz3r, is a latin nerd and claims it is latin for “request”.

From what I understand, jussi is the "first-person singular perfect active indicative" of jubeō, jubēre, that is an alternative form of the Latin verb iubeō, iubēre, that means "to command, to order".
So jussi means "I commanded" or "I ordered".

Sounds good but it’s a language I don’t understand 😂

Dear @ned

I met you very briefly around this time last year at the Indaba Hotel in South Africa. Today we're having the annual lunch for my mom's birthday at the Indaba and my aunt and uncle and I got onto the Steemit discussion (I just joined about a month ago).
Honestly, I don't know if it will reach you or if it will mean anything at all. I just wanted to say - hang in there. Many people can't grasp the "ride the wave" concept very well, but I think you're doing pretty well. From the sounds of things, people have been gunning for you personally. It must be pretty difficult to feel like you're carrying this all, but you seem to have a community behind you that truly believe in you. I owned a small business when I was 27, I can't even begin to think what it might feel like to manage something of the magnitude you're dealing with. You're doing a fantastic job @ned .

Yay ! A transparent cache service, that is (I guess) exactly what was needed for these performances issues!

So happy it is back to running smoothly again. Good work @steemitdev

Hope that all developer will read this post and will take action.

Well This is really a huge step towards making the apps more fast.

Awesome Post, Keep it up!

hi @steemitdev, @ned


This came up in a #community challenge where people in #GHANA and Africa want to promote #STEEMIT at their various locations.


I like these changes, but where is the Jussi currently drawing data from?

I believe Hivemind isn't ready yet, and wasn't easily able to understand which of the other sources are being used for what.

I tried running the docker SBDS as this seems very useful to me, but the documentation isn't really there yet, I couldn't easily see the DB schema, and getting the data as checkpoints required Amazon S3 permissions I don't have. Are there any public sources for this checkpoint data?
