nuxt-mail

Adds email sending capability to a Nuxt.js app. Adds a server route, an injected variable, and uses nodemailer to send emails.

Does not work for static sites (via nuxt generate) because the module creates a server route.

Install

# npm
$ npx nuxi module add nuxt-mail

# Yarn
$ yarn nuxi module add nuxt-mail

Configuration

Add the module to the modules array in your nuxt.config.js. Note to add it to modules instead of buildModules, otherwise the server route will not be generated.

// nuxt.config.js
export default {
  modules: [
    ['nuxt-mail', {
      message: {
        to: 'foo@bar.de',
      },
      smtp: {
        host: "smtp.example.com",
        port: 587,
      },
    }],
  ],
  // or use the top-level option:
  mail: {
    message: {
      to: 'foo@bar.de',
    },
    smtp: {
      host: "smtp.example.com",
      port: 587,
    },
  },
}

The smtp options are required and directly passed to nodemailer. Refer to their documentation for available options. Also, you have to pass at least to, cc or bcc via the message config. This has security reasons, this way the client cannot send emails from your SMTP server to arbitrary recipients. You can actually preconfigure the message via the message config, so if you always want to send emails with the same subject or from address, you can configure them here.

The module injects the $mail variable, which we now use to send emails:

Nuxt 3

Via composable

<script setup>
const mail = useMail()

mail.send({
  from: 'John Doe',
  subject: 'Incredible',
  text: 'This is an incredible test message',
})
</script>

Via injected variable

<script setup>
const { $mail } = useNuxtApp()

$mail.send({
  from: 'John Doe',
  subject: 'Incredible',
  text: 'This is an incredible test message',
})
</script>

Via Options API

<script>
export default {
  methods: {
    sendEmail() {
      this.$mail.send({
        from: 'John Doe',
        subject: 'Incredible',
        text: 'This is an incredible test message',
      })
    },
  },
}
</script>

Nuxt 2

For Nuxt 2, you need to install @nuxtjs/axios and add it to your module list before nuxt-mail:

// nuxt.config.js
export default {
  modules: [
    [
      '@nuxtjs/axios',
      ['nuxt-mail', { /* ... */ }],
    }],
  ],
}

Then you can use the injected variable like so:

<script>
export default {
  methods: {
    sendEmail() {
      this.$mail.send({
        from: 'John Doe',
        subject: 'Incredible',
        text: 'This is an incredible test message',
      })
    },
  },
}
</script>

Note about production use

When you use nuxt-mail in production and you configured a reverse proxy that hides your localhost behind a domain, you need to tell @nuxt/axios which base URL you are using. Otherwise nuxt-mail won't find the send route. Refer to @nuxt/axios options on how to do that. The easiest option is to set the API_URL environment variable, or set something else in your nuxt.config.js:

// nuxt.config.js
export default {
  axios: {
    baseURL: process.env.BASE_URL,
  },
}

Multiple message configs

It is also possible to provide multiple message configurations by changing the message config into an array.

// nuxt.config.js
export default {
  modules: [
    ['nuxt-mail', {
      message: [
        { name: 'contact', to: 'contact@foo.de' },
        { name: 'support', to: 'support@foo.de' },
      ],
      ...
    }],
  ],
}

Then you can reference the config like this:

mail.send({
  config: 'support',
  from: 'John Doe',
  subject: 'Incredible',
  text: 'This is an incredible test message',
})

Or via index (in which case you do not need the name property):

mail.send({
  config: 1, // Resolves to 'support'
  from: 'John Doe',
  subject: 'Incredible',
  text: 'This is an incredible test message',
})

Also, the module does not work for static sites (via nuxt generate) because the module creates a server route.

Setting up popular email services

Gmail

You have to setup an app-specific password to log into the SMTP server. Then, add the following config to your nuxt-mail config. Looks like there are multiple ways to configure Gmail, so it's best to try out the options:

// nuxt.config.js
export default {
  modules: [
    ['nuxt-mail', {
      smtp: {
        service: 'gmail',
        auth: {
          user: 'foo@gmail.com',
          pass: '<app-specific password>',
        },
      },
    }],
  ],
}

// nuxt.config.js
export default {
  modules: [
    ['nuxt-mail', {
      smtp: {
        host: "smtp.gmail.com",
        port: 587,
        auth: {
          user: 'foo@gmail.com',
          pass: '<app-specific password>',
        },
      },
    }],
  ],
}

Debugging mail errors

If the mail doesn't get sent, you can debug the error using the browser developer tools. If a 500 error is thrown (check out the console output), you can find the error message in the Network tab. For Chrome users, open the Network tab, then find the "send" request. Open it and select the "Response" tab. There it should show the error message. In most cases, it is related to authentication with the SMTP server.
