Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Stripe Financial Connections
Hostile integrations using scripts to obtain financial data is trivial. Frameworks such as:
https://github.com/teampoltergeist/poltergeist
is an excellent example of such a framework. Implementing "bank drivers" using such frameworks would not be difficult.
Plaid and others seem to have done an awesome job scaling the hostile integration pattern. However, the idea that Stripe decided to build this in-house rather than rely on Plaid is perfectly reasonable.
After all, the tools to implement such a product are well known.

Migrating Selenium system tests to Cuprite
In our project, we’ve been running system tests (then called rather "Feature tests") since around 2016. System tests use a real browser in the background and test all layers of a Rails application at once: from the database all the way up to the nuances of JavaScript loaded together with the web pages. Back then, we wrote our system tests using Capybara with Poltergeist, a driver that ran a headless Phantom JS browser. Since this browser stopped being actively developed, we migrated our test suite to the Selenium / Webdriver wrapper around Chrome browser around ~2018. Chrome was itself fine for tests automation but the Selenium API was quite limited and we had to rewrite several Poltergeist features using 3rd party gems and tools.

RVTWS: a Ruby stack for modern web apps
Actually, Stimulus is pretty cool because you can compose multiple pre-built behaviors into one Stimulus controller, for a sort of functional approach to component behaviors. The tradeoff is that a growing web of Stimulus controllers (plus HTML data attributes associated with them) can become complex and hard to understand.

Tailwind style CSS transitions with StimulusJS
The stimulus-use project is a collection of reusable behaviors for Stimulus. If you are familiar with React, this project is similar to React’s hooks system, but for Stimulus controllers.

Pagination and infinite scrolling with Rails and the Hotwire stack
To make using the IntersectionObserver API easier, we will add the wonderful stimulus-use package to our application. This is not a requirement, but it does simplify the code a bit.
- Autocomplete search with Hotwire (zero lines of Stimulus or other JS)

Upgrade to Stimulus 3, say bye to IE11, and celebrate 🎉
Finally, as we recently added the Stimulus-Use library to our project, we made sure to upgrade it to current beta which supports Stimulus 3.

Hotwire: best practices for stimulus
As you’ll see below, I am importing useClickOutside from stimulus-use, it’s a great library with small, composable helpers, I urge you to check it out!

Migrating Selenium system tests to Cuprite
For example, we have a few ”live search“ fields, backed by back-end Fetch requests, on some pages. The live search function was usually triggered by the keyup event and Cuprite was such a fast typewriter that it frequently sent multiple requests almost at once. If some of the responses got a bit late or out of sync, the front-end JavaScript code began hitting issues. We solved this by adopting a technique called debouncing and, frankly, we should have done this since the beginning. By the way, we used the useDebounce module from the marvelous Stimulus-use library to achieve this.
