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.

[AskJS] JavaScript for data processing
We used to use a library called Pond.js, https://github.com/esnet/pond, but the reliance on Immutable.JS caused some performance pitfalls, so we wrote a system from scratch that deals with data in a batched streaming fashion. A lot of the concepts were borrowed from a Rust library called timely-dataflow, https://github.com/TimelyDataflow/timely-dataflow.

react query or redux toolkit for frequently changing data (with websocket) ?
An easy way to cache data in the short term would be to insert the timeseries data into a BTree (I'd recommend this implementation). When you mount the component, first request the window of your chart from the BTree, inserting the events, and simultaneously request the data from the server. Once the data from the server comes in, wipe everything then redraw with the data from the server.

[AskJS] JavaScript for data processing
Separately to the processing, the in-memory database we use is https://github.com/qwertie/btree-typescript, again able to support millions of data points per second.
What are some alternatives?
