I can't get a vanilla Rails + Turbolinks app working

14 2 1

Hi  Guys,

I just went through the Rails & Turbolinks tutorial - because I am creating a Shopify app for the first time. I got to the stage where my app is loading but all I am seeing is the "Loading..." page which is the 'SplashPage#Index' but it isn't redirecting to my 'Home#Index' like I expect.

I am using Rails, Ruby 3.0.1 and I am not using React. I want to just use Rails & Turbolinks if possible to build my app, so that's why I chose that tutorial.

This is the server log (note, I blanked out my IP address for privacy purposes).

Started GET "/?hmac=5e2e8c366d75e39831b775be635e4118a99c&host=bWFueS1wcmXlzaG9waWZ5LmNvbS9hZG1pbg&locale=en&new_design_language=true&session=7deccadd83c28b82dd4dd2902fff5c76573f365f637c2a&shop=random-shop.myshopify.com&timestamp=1619310003" for 69.160.XXX.XX at 2021-04-24 19:20:04 -0500

What could be causing this behaviour and how can I fix it?

What other code would you need to see to help me troubleshoot this properly?

Edit 1

Not sure if this has any bearing on anything, but from my `rails console`, when I do `ShopifyApp.configuration.api_key`, I get `nil` returned.

I did some more debugging and this is what I found.

The JS Console produces the following error:

Not sure what causes this and how to fix it or even how to debug it properly.

This is an accepted solution.

I finally figured it out. Even though I am not using NPM explicitly, I needed to still include the `@shopify/app-bridge` utilities into my JS package pipeline.

I did this by running the following commands:

    $ yarn add @Shopify/app-bridge
    $ yarn add @Shopify/app-bridge-utils

It worked like a charm, and now everything is good to go.
