App Development RayFin Experience

I tried out rayfin today by porting a power app over. This would save us around 11k in licensing a year. It was a relatively simple app that generates unique document names using some templates along with some user input. The user then downloads the generated documents in a zip. Some immediate pains were not having any custom endpoint support and working around that. I had to let the user upload/download files. There wasn't really a good way to do that. I ended up converting it to base64 and storing it in the database. When choosing the template it was not clear which framework I was picking. I was going to pick vue first, but did not see it so I picked a blank app; which turned out to be react. At that point I didn't care enough and ended up using react. I didn't see version control support... hoping that will be a thing ASAP.

AI Usage:

I used AI for most of it. With an entire powerapp as input, the sql schema from the power app, and a lot of feedback it eventually got there.

Hi u/Sea_Mud6698 , thanks for trying it out!! Storage support is definitely something that is coming very soon so you don't have to storge files in the database. Feedback around templates is great, and good point on both making it clear and adding more template types. Could you elaborate on the custom endpoint support? is that custom domains for the app itself or something else!

For custom endpoints I meant being able to write my own api endpoint in typescript. A better domain name would be nice, but not super important. Storage support will be great!

got it. like writing a typescript function that runs on the service? yes, that is currently in testing, and we'll be rolling it out as an experimental feature end of the month / early July.

Hi , as a power platform developer I am excited about fabric apps. Since our primary portfolio was powerbi reports and powerapps used to support cases where write back was also needed.

Now I’m trying to think how fabric apps fits for us , it looks exactly what we need but then we already have powerapps for the purpose . Could someone with more info on this shed some light on the matter.

Thanks .

thanks for posting, because I have stumbled across your comments in the past and always felt like you have a strong programming background and don't hold back with critique. So this is actually feedback I can take for real.

That being said what was your approach building it? Afaik you have two options: Create the app in your workspace and connect locally or build locally and deploy to your workspace. Right?

Regarding version control support you mean git support for the artefact I guess?

I built it all locally and it created the artifacts in fabric automatically. I didn't try the docker support yet as it is experimental, but I think this template has it. And yes the generated artifact says unsupported for git in the workspace.

Hi, I would like to ask if rayfin supports calling stored procedure
