Capture a template output for reasons like sending e-mail?

acidjazz opened this issue 2 years ago · 12 comments

I want to use templates to send e-mails via AWS SES - is this possible with fiber?

Answer 1 · 2022-09-22T04:50:20.000Z

I was able to capture the html doing this:

buffer := new(bytes.Buffer)
err := c.App().Config().Views.Render(buffer, "demo", render.H{
	"hostname": setting.Core.WebURL,
	"demo":     params,
})

if err != nil {
	return render.Error(c, err.Error())
}

you can also use the template system without the fiber app

Since the email is related to the endpoint (contact form, login button, notifications) it would be nice to do this in fiber.

My above examples is working well, maybe we can add a c.ReturnRender() or something?

I'll give a PR a shot once I get some time

but there are already several render functions ?
the view engine has one where it assigns the output to a writer, which in the case of fiber is the context output and fiber also has a render method where you can specify which template to render

no extension of functionality needed

Do any of these functions return the html as a string? AKA what I need ?

no return as string, it gives this string to a writer

Answer 7 · 2022-09-22T07:02:59.000Z

all the view engines in our template make that

OK so then how would I use this to get the HTML to send in an email?

Answer 9 · 2022-09-22T07:13:28.000Z

you already use it

only you don't have to go through the app configuration but just use the engine instance

i don't see any other method to return as string as necessary

Answer 10 · 2022-09-22T13:54:02.000Z

How do I go after the engine instance itself?

I find it pretty necessary to be able to route templates to other sources like email - these are standard things API's do.

Answer 11 · 2022-09-22T14:09:29.000Z

correct, these are also possible with the frameworks but have to be implemented by yourself

a framework cannot offer solutions for every case, otherwise it becomes too big and overloaded

as said, it is possible using template engine
-> you can put this in a self written function and provide it to others via packages

Answer 12 · 2022-09-22T14:58:24.000Z

I see the framework as the solution in this case - I have everything I need to send out my notification/confirmation/contact/etc - I have the logged in user and all of their information

All I have to do next is something like

if _, err := aws.SendEmail(c.Locals("user").email, "Contact Us Form", html); err != nil {
	return render.Error(c, err.Error())
}

I think it makes perfect sense this functionality is w/in fiber since you're already providing Templating and this framework is angled towards API's.

To be completely honest I'm building an entirely JSON-only API - so E-mail is the only reason I'm even using Templating
