A standard Phoenix app contains a priv/repo/seeds.exs script file, which populates a database when it is run, so that developers can work with a conveniently prepared environment.

Plausible Analytics
Simple, open source, lightweight (< 1 KB) and privacy-friendly web analytics alternative to Google Analytics.
I just swapped out Google Analytics with Plausible for AINIRO.IO. It’s only been a week, but so far I am super jazzed about it. First of all, Plausible doesn’t use cookies, so I can completely drop all cookie disclaimers and popups I had because of GDPR. Second of all, the site scores significantly better on load time. This results in a 10x better user experience for my website visitors, while making sure the website is still 100% conforming to GDPR laws.

Project mention: A Technical Dive into PostgreSQL's replication mechanisms | news.ycombinator.com | 2024-01-11
You can LISTEN/NOTIFY. Or you can use logical replication and a custom subscriber.[1] Supabase uses the latter.[2]

firezone
Open-source VPN server and egress firewall for Linux built on WireGuard. Firezone is easy to set up (all dependencies are bundled thanks to Chef Omnibus), secure, performant, and self hostable.

The best language for the task at hand, when presented with time constraints, is the one that you already know well. OP said in the article that they authored Papercups [1]. Adopting Elixir for a websocket-push service makes a lot of sense, then. However, why don't you learn Elixir, some OTP, and then reconsider that question? You could be missing out.

Project mention: Ask HN: How does your CI/CD stack look like today? | news.ycombinator.com | 2023-07-30
Another https://dagger.io fan here. Have been using it since late 2021 to continuously deploy a Phoenix app to Fly.io: https://github.com/thechangelog/changelog.com/pull/395. Every commit goes into production.
This is what the GHA workflow currently looks like: https://github.com/thechangelog/changelog.com/blob/c7b8a57b2...
FWIW, you can see how everything fits together in this architecture diagram: https://github.com/thechangelog/changelog.com/blob/master/IN...

You can actually have "background jobs" in very different ways in Elixir.
> I want background work to live on different compute capacity than http requests, both because they have very different resources usage
In Elixir, because of the way the BEAM works (the unit of parallelism is much cheaper and consume a low amount of memory), "incoming http requests" and related "workers" are not as expensive (a lot less actually) compared to other stacks (for instance Ruby and Python), where it is quite critical to release "http workers" and not hold the connection (which is what lead to the creation of background job tools like Resque, DelayedJob, Sidekiq, Celery...).
This means that you can actually hold incoming HTTP connections a lot longer without troubles.
A consequence of this is that implementing "reverse proxies", or anything calling third party servers _right in the middle_ of your own HTTP call, is usually perfectly acceptable (something I've done more than a couple of times, the latest one powering the reverse proxy behind https://transport.data.gouv.fr - code available at https://github.com/etalab/transport-site/tree/master/apps/un...).
As a consequence, what would be a bad pattern in Python or Ruby (holding the incoming HTTP connection) is not a problem with Elixir.
> because I want to have state or queues in front of background work so there's a well-defined process for retry, error handling, and back-pressure.
Unless you deal with immediate stuff like reverse proxying or cheap "one off async tasks" (like recording a metric), there also are solutions to have more "stateful" background works in Elixir, too.
A popular background job queue is https://github.com/sorentwo/oban (roughly similar to Sidekiq at al), which uses Postgres.
It handles retries, errors etc.
But it's not the only solution, as you have other tools dedicated to processing, such as Broadway (https://github.com/dashbitco/broadway), which handles back-pressure, fault-tolerance, batching etc natively.
You also have more simple options, such as flow (https://github.com/dashbitco/flow), gen_stage (https://github.com/elixir-lang/gen_stage), Task.async_stream (https://hexdocs.pm/elixir/1.12/Task.html#async_stream/5) etc.
It allows to use the "right tool for the job" quite easily.
It is also interesting to note there is no need to "go evented" if you need to fetch data from multiple HTTP servers: it can happen in the exact same process (even: in a background task attached to your HTTP server), as done here https://transport.data.gouv.fr/explore (if you zoom you will see vehicle moving in realtime, and ~80 data sources are being polled every 10 seconds & broadcasted to the visitors via pubsub & websockets).

tesla
The flexible HTTP client library for Elixir, with support for middleware and multiple adapters.
I haven’t used commanded, exmachina, or ash:
- Tesla has a mode which can be used completely without macros, and I am increasingly encouraging that it be the only way that it is used. So does the author (as of 2020): https://github.com/elixir-tesla/tesla/issues/367#issuecommen...
There is also `req` mentioned in a recent post as an alternative (it looks good, but I am still playing with it to see if it is a suitable replacement for Tesla in all cases).
- Absinthe is something of a compiler itself, because it has to strictly define things the way that is specified in the GraphQL spec. You can now import an SDL file, but you still need to hook resolvers and middleware into it. Honestly, I don’t think that the schema definitions in JS/TS are much better for GraphQL in terms of readability.
Being heavily macro-based means that there are sharp edges that are harder to work around when you want to add your own macros for code reuse purposes. That said, aside from the schema definition, Absinthe is entirely usable without macros. Within the schema definition, Absinthe isn’t making anything up, it’s using the same basic definitions that the GraphQL spec do, adapted for Elixir syntax.
Exmachina didn’t interest me because I don’t think much of factory_bot (which used to be called factory_girl), as I saw it abused far more than used well (IMO, it’s impossible to use correctly). Ash…looks like an interesting experiment, but I don’t know that there’s a lot of pick-up with it compared to Phoenix. And I have yet to find a use for CQRS/ES, so there’s no reason for me to play with commanded. I certainly wouldn’t consider any of these three to be "major" players in Elixir. Tesla and Absinthe? Yes.
