App

Expected behavior

My app should be open

Actual behavior

In web directory I removed Laravel app and I try to configure Symfony app. I added files to directory and I changed web/shopify.web.toml file like this:

type="backend"

[commands]
dev = "symfony server:start"

I use command npm run dev and url doesn't works.

Stack trace

user my-app % npm run dev                                       

> my-app@1.0.0 dev
> shopify app dev

Hi @sebastianpisula. Thanks for bringing up this issue.
The template used to create the application configures vite in the frontend to redirect the requests to the backend
https://github.com/Shopify/shopify-frontend-template-react/blob/f720a83458f3e83db4f2b5e85644345fc658cd32/vite.config.js#L54:L61

When you run the app using the CLI, there are some env variables set when the backend and frontend processes are run.
PORT, SERVER_PORT, BACKEND_PORT
You should configure symfony to run the http server listening to one of those three env variables.

In your logs the CLI has run the backend using the random port 65384 and the symfony server seems to run using the port 8000 by default. That's the reason you can see the error

2023-03-06 18:13:49 | frontend | 7:13:49b/PM [vite] http proxy error:
2023-03-06 18:13:49 | frontend | Error: connect ECONNREFUSED 127.0.0.1:65384
2023-03-06 18:13:49 | frontend |     at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16)

I don't know anything about symfony but maybe configuring the toml like this could do the trick `dev = "symfony server:start --port=${PORT}"

Please, let me know if this works for you.

Thanks, great idea but I have errors:

Help:

  The local web server is optimized for local development and MUST never be used
 in a production setup.

I modified web/frontend/vite.config.js and I changed line #17 from:

    target: `http://127.0.0.1:${process.env.BACKEND_PORT}`,

to:

  target: `http://127.0.0.1:8000`,

and in tome file without port:

dev = "symfony server:start"

and works!

But I not sure that hardcoded proxy is good way. What you think ?

[alvaro-shopify]

@sebastianpisula , sorry for the wrong tip. I don't know anything about how symfony sets the port, you should do a little research and set it to one of the three env variables PORT, SERVER_PORT, BACKEND_PORT

That temporary solution is going to work but it's specific for your scenario. Using the env variable it's the only way to have a generic solution

Closing as it sounds like this was a specific config issue. Feel free to re-open with more context if this affects more use cases. Thank you!
