Please provide more "global" email template variables...

[vonschappler]

It just came to my attention that some variables like for example {{ .SiteUrl }} should be set for all email templates.

Reason why Im saying this it's because I saw this odd behavior:

1. "auth.email.template.*"

2. "auth.email.notification.*"

is causing a break on the custom email templates created (like not redirecting to the correct links that relies on {{ .SiteUrl }} or not rendering / linking the images correctly, if they are hosted into {{ .SiteUrl }} as shown in the images above (case 1 and case 2)

I would kindly suggest the auth team to consider setting {{ .SiteUrl }} and all other possible "global / project variables" accessible to all email templates to avoid the behavior shown above!

Since we have access to {{ .SiteUrl }} and would need access to that for any and all email templates, I suppose that is for avoid hardcoding its value into our project, then I ask: "Why this "possibly global variable" can't be accessed in all email templates?"

Note

{{ .SiteUrl }} was one of the variables I noticed that should be exposed to all email templates, but there could be more variables to se considered as globally exposed to all email templates!

Suggestion:
Enable access to possibly global variables in all email templates to remove the need of hard-coded values

If it's not available in the notification emails then it's a bug and should be raised as such rather than a feature request. This is indeed a bug as I just checked the code base and it's missing the externalURL aka SiteURL in the code https://github.com/supabase/auth/blob/master/internal/mailer/templatemailer/templatemailer.go#L426-L487. You should open this on the https://github.com/supabase/auth repo as a bug in the issues.

I added this as a feature request per indication of someone helping me regarding this on Supabase's discord.
I'll be moving this then to an issue.
