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.

LLRT: A low-latency JavaScript runtime from AWS
pljs (https://github.com/plv8/pljs) is a postgres language plugin that also uses quickjs. given how much faster the startup is compared to v8, and that most postgres functions are very small and do very little compared to a node.js program, it is quite good.
I can definitely see aws' lambda operations gaining quite a bit from this.

PLJS – JavaScript Language Plugin for PostreSQL
a bit more than an experiment at this point. pljs, even in its early state, has some very good results: https://github.com/plv8/plv8/issues/531#issuecomment-1627883...
passing through v8's javascript/c++ membrane has always been painful, and appears to be getting worse.

Sending Email From Postgres
From here you'll write a send_email function in Postgres that calls the API. I initially wrote the entire function in PLpgSQL and spent an entire day to get it debugged and working. And even then I wasn't happy with it. In my opinion that language is unintuitive and difficult to learn and debug. I switched over to PLV8, an extension for Postgres that supports writing functions in Javascript. It takes one click in the Supabase UI to enable this extension, and it will save hours and hours of time.

I wrote a database engine in Typescript
You jest, but the evil geniuses at plv8 have already done it for Postgresql.

Surrealdb – FOSS document-graph database, for the realtime web in Rust
To be honest I haven't used it, but I've extensively used pl/pgsql and a little pl/ruby, and know that https://plv8.github.io/ exists - it might be what you're looking for and it's on my list of things to play with

Show HN: Postgres.js – Fastest Full-Featured PostgreSQL Client for Node and Deno
but, let's take your straw man a little further. let's suppose that all of the actual parsing is done for you already, and all you're doing is iterating through the data structure, creating objects through the c++ api, and calling it good. that should be faster than calling the c++ JSON.parse(), shouldn't it? since we don't have to actually parse anything, right? no, it's actually much slower. you can see this in action at https://github.com/plv8/plv8/blob/r3.1/plv8_type.cc#L173-L60...
again, we're not talking about whether javascript in an interpreter is faster than c++, we're talking about whether v8's api causes enough slowdown that some workloads that require a lot of data between c++ and javascript are slower than the same workload that requires very little data between c++ and javascript ... because passing through v8's c++/javascript membrane is slow.

What are some alternatives?
