StreamBuilder: our open-source framework for powering your dashboard.

Today, we’re abnormally jazzed to announce that we’re open-sourcing the custom framework we built to power your dashboard on Tumblr. We call it StreamBuilder, and we’ve been using it for many years.

First things first. What is open-sourcing? Open sourcing is a decentralized software development model that encourages open collaboration. In more accessible language, it is any program whose source code is made available for use or modification as users or other developers see fit.

What, then, is StreamBuilder? Well, every time you hit your Following feed, or For You, or search results, a blog’s posts, a list of tagged posts, or even check out blog recommendations, you’re using this framework under the hood. If you want to dive into the code, check it out here on GitHub!

StreamBuilder has a lot going on. The primary architecture centers around “streams” of content: whether posts from a blog, a list of blogs you’re following, posts using a specific tag, or posts relating to a search. These are separate kinds of streams, which can be mixed together, filtered based on certain criteria, ranked for relevancy or engagement likelihood, and more.

On your Tumblr dashboard today you can see how there are posts from blogs you follow, mixed with posts from tags you follow, mixed with blog recommendations. Each of those is a separate stream, with its own logic, but sharing this same framework. We inject those recommendations at certain intervals, filter posts based on who you’re blocking, and rank the posts for relevancy if you have “Best stuff first” enabled. Those are all examples of the functionality StreamBuilder affords for us.

So, what’s included in the box?

The full framework library of code that we use today, on Tumblr, to power almost every feed of content you see on the platform.

A YAML syntax for composing streams of content, and how to filter, inject, and rank them.

Abstractions for programmatically composing, filtering, ranking, injecting, and debugging streams.

Abstractions for composing streams together—such as with carousels, for streams-within-streams.

An abstraction for cursor-based pagination for complex stream templates.

Unit tests covering the public interface for the library and most of the underlying code.

What’s still to come

Documentation. We have a lot to migrate from our own internal tools and put in here!

More example stream templates and example implementations of different common streams.

If you have questions, please check out the code and file an issue there.

already got a blazed marvel post. the adpocalypse is closer than we think so heres your daily PSA

don't interact with corporate tumblr accounts

yes even to dunk on them. i don't care if you have the sickest burn of the century lined up, don't even give them the time of day

the eventual and inevitable fall of twitter marks a change in the advertising industry, and tumblr is unclaimed territory. if we want tumblr to remain the social media bastion it has become, it needs to remain as unappealing to corporations as possible. do not engage. in a marketing strategist's eyes, any kind of attention is good attention. don't "silence, brand" them. don't kungpowpenis them. don't send them hate anons. don't hate-follow them. corporate tumblrs are not a single entity and they will not be harassed off this site. we only have a shot at repelling them because of tumblr's lack of an algorithm. so turn off recommended posts on your dashboard, put it chronological order, and install an adblocker. if you don't seek out these blazed posts and actively ignore them when they happen upon you, the corporations will starve. in this case, the best kind of protest is a silent one

Longest application process ever. So many interview rounds. So much traveling.

My cartoon for this week’s New Scientist magazine.

Which path should he choose?

The path of the warrior, the path of the scholar, or the path of the artist?

Thank you, /r/ProgrammerHumor, I love you endlessly.
