In the picture, the term user is sometime in singular and sometime in plural: Is that Ok?

@furkan3ayraktar Mb this demo project(and lein template) should contain .dir-locals.el? It will reduce friction for Emacsers.

Hi team,

I checked the code a bit and seems for this example app there's no error handling for:

• database operations
• rpc calls

What will happen to current example app if the disk of the database server is full?

I also posted a similar question in the forum https://polylith.freeflarum.com/d/7-distributed-error-handling-for-microservice-deployment-style

Guess this is an important piece if we want to build a real application, since extensive error handling will actually shape the interface quite a bit, increasing the development cost.

Hi I'm having trouble running lein ring server-headless in environments\development. It's giving me the following error:
Could not locate clojure/realworld/rest_api/api__init.class or clojure/realworld/rest_api/api.clj on classpath. Please check that namespaces with dashes use underscores in the Clojure file name.
I'm using leiningen v 2.8.3, updated lein-ring to 0.12.5. I've also checked namespaces using dashes though I don't think it could be the issue. I also could not create symbolic links when creating new components.

I'm using cider, M-x cider-jack-in-clj,

I haven't been able to find any Polylith examples which use a real, realworld database like Postgres (or MySQL etc.). I have a few Clojure web services which use Postgres + connection pooling (hikari), though I have no idea how to incorporate that into a Polylith project.

Hi,

1. Install the [Polylith tool](https://github.com/polyfy/polylith#installation)

this link from the readme just puts you to the polilith repo, I guess there is no installation section anymore or something.

Update the doc to reflect that we now use :local/root when specifying which bricks to include in a project.

For example this sentence:
If you look at the directory projects/realworld-backend, you will see a standard deps.edn file. The magic here is the project's deps.edn file which refers to the sources, resources and tests of actual components and bases.

Here we could also link to the deps.edn file.

Sorry for the stupid question, I've never used Closure before and just installed lein today for this demo and noticed this error:

$ lein ring server-headless
'ring' is not a task. See 'lein help'.

Please advice, thank you.

Instead of querying the database with user's JWT, it could be nice to validate the token with clj-jwt and extract the user id from claims. Then, the database can be queried by the user id instead of the token. This will eliminate the need for saving the JWT in to the database in the first place.

Thanks to @stask for pointing out this issue.

I wanted to try to run this application, but when I checked it out I couldn't get it to build. It tosses a large stacktrace while building the systems/realworld-backend (attached below).

lein -v reports Leiningen 2.9.1 on Java 1.8.0_202 OpenJDK 64-Bit Server VM

According to the latest tweet, and my own experience with this new version of the plugin, you no longer need the Cursive-specific instructions to replace :extra-deps with :extra-paths. Version 1.13.0 of the Cursive plugin fixes this. I'm using the EAP release of IntelliJ, though today I just updated to the Beta release and maybe that means things can work without the EAP channel.

Either way, :local/root works now with Cursive and you can update the readme.

Question

In the clojure.realworld.database.schema you define comment-table and all other tables don't have the -table suffix. Is there a reason for that? Most probably I have limited view on this and trying to figure out what is the rationale here.

Thanks for creating this!
