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.
pg-mem
- Setting up PostgreSQL for running integration tests
-
Show HN: I open-sourced the in-memory PostgreSQL I built at work for E2E tests
I've used pgmem https://github.com/oguimbal/pg-mem for the last couple of years for the same thing.
-
Ask HN: How do you test SQL?
I was wondering the other day how to classify tests that use a test double like pg-mem, which isn't a mock but isn't the Dockerized test DB either :

How to test nestjs modules?
In my case, I use TypeORM with PostgreSQL, and there's pg-mem to run an instance in memory, it supports most of the common functionality of PostgreSQL but you will need to do some adjustment to your code to be within the limits.
-
Working with offline data
Postgres in the browser is possible through pg-mem: "pg-mem is an experimental in-memory emulation of a postgres database" but it also suffers from no persistence. If you can persist to a file somewhere then read it in on startup (and if your local data isn't huge) this might work.

Haskell as a first timer - Am I missing something ? Or is something broken ?
Dont get me wrong: I am trying to contribute to opensource as well, so I get that supporting small projects can be demanding. There's nothing wrong in not spending your weekends on OS. But not asking for help, nor specifying that a project is unmaintained, nor even answering issues & pull requests for years feels just wrong.
-
Ask HN: What Are You Working On?
A pure Javascript in memory emulation of Posgres, to help writing better node tests https://github.com/oguimbal/pg-mem
-
pg-mem, an in memory postgres DB instance for your unit tests, is now bound to multiple libraries (Knex, Typeorm, Slonik, pg, pg-promise) ... suggestions for the next one ?
Okay, I had a bit of spare time,I've implemented that, and it is now available with [email protected]
-
Zero delay development & unit testing iterations
To get a glimpse of what I'm talking about, you can clone this repo and follow "Development" instructions (by the way this is a small OS lib I maintain, I wrote about it here)
LIPS
- LIPS: Powerful Scheme based Lisp interpreter in JavaScript
-
(Learn 'Scheme)
Sweet, I'll have to give that a go :)
Another option in browser land is lips[0], which exclusively targets a js backend.

All Web frontend lisp projects
For Scheme implementations there are LIPS and biwascheme. I haven't done more than play around with them, so I can't really give an informed opinion about pros and cons or favorites.

Extending a Language — Writing Powerful Macros in Scheme
Your example revealed a bug in my Scheme interpreter. This is an example that fails to match:
-
What other Scheme parser tricks do you know?
In my interpreter, LIPS Scheme, vector literal syntax is created using a syntax extension, a token that is mapped to a function or a macro. So you can use things like this:
-
How to list defined symbols?
I'm not sure about other Scheme interpreters but in my interpreter LIPS Scheme, there is (env) function that returns a list of symbols. You can also access environment objects e.g. (current-environment) return object that is used internally. And you can even access the scope chain because the env object has __parent__ property that returns the parent scope.

May I see some of your projects? :)
Few of my Open Source projects: * jQuery terminal * LIPS Scheme * Gaiman * Sysend * Wayne

Async / Await in Scheme
(define promise (--> '>(fetch "https://lips.js.org/") (then (lambda (res) (res.text))) (then (lambda (text) (. (text.match #/\s*([^>]+?)\s*<\/h1>/) 1)))))

Yes we are men. Men is what we are.
ngl when I first saw the headline my first thought was, “Wait, bring CAR into JavaScript? Make it a Lisp? But hasn't it already been done?”
-
If you were hired to create a new distribution of Lisp, what would you include?
Languages like Biwa Scheme and LIPS Scheme are good for running Scheme in the browser. But I would prefer compiling Scheme code to JavaScript in the server, then serving the compiled JavaScript image to the browser.
What are some alternatives?
NeDB - The JavaScript Database, for Node.js, nw.js, electron and the browser
scheme-lsp-server
Prisma - Next-generation ORM for Node.js & TypeScript | PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB and CockroachDB
biwascheme - Scheme interpreter written in JavaScript
Lowdb - Simple and fast JSON database
murex - A smarter shell and scripting environment with advanced features designed for usability, safety and productivity (eg smarter DevOps tooling)
typescript-clean-architecture - It is my attempt to create Clean Architecture based application in TypeScript.
atbswp - A minimalist macro recorder
maplibre-gl-js - MapLibre GL JS - Interactive vector tile maps in WebGL2
osmosis-js - JS reference implementation of Osmosis, a JSON data store with peer-to-peer background sync
database-js - Common Database Interface for Node
spleeter-web - Self-hostable web app for isolating the vocal, accompaniment, bass, and drums of any song. Supports Spleeter, D3Net, Demucs, Tasnet, X-UMX. Built with React and Django.
