Overview
For mails supastarter integrates React Email which enables you to write your mails in React.
Why React Email:
It gives you the ability to style your mails with
Tailwind CSS just like in your application. Of course the config from your app
is reused for your mails. It also gives you the ability to use components in
your mails, so you can build a generic template and use it in all your mails.
Unfortunately, Svelte ecosystem doesn't have a well maintained library like this.
Providers
In the mail
package in your repository you can find the provider
folder.
There are multiple providers available:
Set from
mail address
Next up, set the from
mail address in the config.ts
file.
This is the mail address that will be used as the sender of all mails. Please make sure that the mail address and domain are verified in your mail provider.
Mail templates
In the mail
package in your repository you can find the templates
folder. In here all your mail templates are
located.
To preview your templates while developing you can run the following command in your terminal:
This will start a local server on port 3005
where you can preview your mails.
If this isn't working for you, try running the following command in the packages/mail/.react-email
subfolder:
Create a mail template
To create a new mail template, simply create a new .tsx in the templates
folder that has a default export of a React
component.
To use variables, just define them as props of your component.
The translation strings for your mail templates are defined in the packages/i18n/translatinons
folder.
Check out the offical docs of React Email for more information on how to use it and the available components.
Register the mail template
Before you can use your new mail template, you have to register it in the lib/templates.ts
file:
Use the mail template
Now you can send a mail with your template using the sendMail
method in your application:
Translations
All mail templates can be translated using the use-intl
(the core library of next-intl
) package. The translations are defined in the packages/i18n/translations
folder.
To use translations in your mail templates, you can use the createTranslator
function from use-intl/core
.
Each mail template is passed the locale
and translations
props. The locale
is the current locale of the user and the translations
are the translations for the current locale.
Per default the sendEmail
function will use the default locale you defined in your config.ts
.
The API uses the sendEmail function to send various mails like the magic link mail or the password reset mail.
In the API we have a locale
variable available in the context which will be automatically read from the users locale cookie, so it will match the selected language of the user for each request.
If you want to send a mail in a specific language you can pass the locale
prop to the sendEmail
function:
