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.

Show HN: Mongita is to MongoDB as SQLite is to SQL
It's a good question and to be accurate, depending on the benchmark, Mongita is about the same speed at SQLite to several-times slower.
There is less happening algorithmically than you would think. Where the tricky slow bits do exist, they have largely fallen into the happy-path of fast data structures in the Python language/stdlib. I also use sortedcontainers for indexes which helped quite a bit (http://www.grantjenks.com/docs/sortedcontainers/).
If you're curious, the benchmark code is in the repo: https://github.com/scottrogowski/mongita/blob/master/benchma...

- I wrote an embedded database (like SQLite) that implements most of the PyMongo/MongoDB API
- I wrote an embedded NoSQL database (embedded as-in SQLite) that implements the PyMongo API.

Show HN: Insomnium – 100% local and privacy-focus fork of Insomnia API client
Yes! I plan to maintain it long-term! I will be rolling out some feature improvements and updates these few weeks.
I still think Kong did a good job in crafting the product. I started using Insomnia in my previous company 3 years ago and our team loved it.
What happened recently felt a little bit like the Unity fiasco (of course, in a much smaller scale). Though as a user I would say Kong had taken a bad turn, I'm still grateful to them for open-sourcing such a fantastic product.
One of the reasons I forked it was because I've read the code and I think it's quite nicely written overall (but unfortunately things like nedb that was used is no longer maintained https://github.com/louischatriot/nedb so it's probably wise to swap out at some point)

Error: Failed to flush to storage
Sounds like node is trying to fsync to an unsupported file system. Top hit on goolge does not look promising: https://github.com/louischatriot/nedb/issues/407

Looking for something like NeDB
You can pick one from this NeDB's issue that fits your needs, or keep using NeDB if it is still working for you, no longer maintained != not working.

How to Design Programs
At least for my needs, NeDB[0] is the best of both worlds for prototyping and early-stage production releases. It's human-readable, on-disk, greppable, still supports indexing and a subset of Mongo features while remaining serverless and in-memory.

Multi Provider Booster Rockets
Local: Local specific logic. For example, code to write to a Nedb table.

default "has vision" token settings
What I'd do to get the best understanding of how NeDB works is to dive into the docs here. The primary things to keep in mind are that there can be other non-JSON data in those files, and that all of the document data is appended and periodically compacted, which means you'll often have an arbitrary number of duplicates and versions within the same file.

Embedded DB for ElectronJS?
I've used https://github.com/louischatriot/nedb before but it may not meet your needs.

Views Of Data
NeDB compatible with MongoDB

Mongita is to MongoDB as SQLite is to SQL
Also, there is a javascript solution called nedb: https://github.com/louischatriot/nedb, which does largely the same thing

I wrote an embedded NoSQL database (embedded as-in SQLite) that implements the PyMongo API.
There is similar project in Javascript called NeDB
What are some alternatives?
indradb - A graph database written in rust
Lowdb - Simple and fast JSON database
lungo - A MongoDB compatible embeddable database and toolkit for Go.
LokiJS - javascript embeddable / in-memory database
mongodb-memory-server - Spinning up mongod in memory for fast tests. If you run tests in parallel this lib helps to spin up dedicated mongodb servers for every test file in MacOS, *nix, Windows or CI environments (in most cases with zero-config).
