Hi, this is my first time asking here. I have a backend made with Go, now I want to pair it with Elm but I don’t know what will be the best fit library to use. I saw elm-spa and elm-pages, but I’m confuse what to pick, btw my frontend also needs authentication, and routing guard. TIA.

Hi @mystique09. Basically all elm application use what is called TEA ([The Elm Architecture](https://guide.elm-lang.org/architecture/)). Using elm in the frontend is very much the same whatever backend you use. You simply need to be able to serve an html and a JS file (where the JS is the result from elm compilation). Some more info about that [in the guide](https://guide.elm-lang.org/interop/).

Regarding how your app is organized, many like the way [Richard’s “Real World”](https://github.com/rtfeldman/elm-spa-example) example app is structured.  
Now there also exists a few helper frameworks such as [Elm Land](https://elm.land/) (successor to elm-spa).  
And a few static site generator libraries such as [elm-pages](https://elm-pages.com/).

If not already, I’d suggest registering to the [elm slack](https://elm-lang.org/community/slack), where you can more easily find out what really fits your needs.

I use elm-spa and like it a lot. Here is repo:

`api` and `frontend` directories may be of interest. We build and compress the [elm.js](https://github.com/simpleiot/simpleiot/blob/master/frontend/public/elm.js.gz) file (only 50KB) and then embed that using go-embed. We then serve the compressed file by using this HTTP wrapper that decompresses the file on the fly:
