Plaintext

Maizzle can automatically create plaintext versions of your HTML emails.

Usage

Generate a plaintext version for all your email templates by adding a plaintext key to your templates source in config.js:

config.js

module.exports = {
  build: {
    templates: {
      plaintext: true,
    },
  },
}

Custom path

You may configure where the plaintext files are output and what file extension they have.

config.js

module.exports = {
  build: {
    templates: {
      plaintext: {
        destination: {
          path: 'dist/brand/plaintext',
          extension: 'rtxt',
        }
      },
    },
  },
}

The path option must be a directory path, otherwise a single plaintext file will be generated for all of your emails.

Using multiple Template sources? You can enable plaintext on a per-source basis:

config.js

module.exports = {
  build: {
    templates: [
      {
        source: 'src/templates',
        destination: {
          path: 'build-1',
        },
        plaintext: true // build-1 folder only: output plaintext files next to the HTML counterparts
      },
      {
        source: 'src/templates',
        destination: {
          path: 'build-2',
        },
        // build-2 folder only: output plaintext files in the `plaintext` subdirectory, with custom extension
        plaintext: {
          destination: {
            path: 'build-2/plaintext',
            extension: 'rtxt'
          }
        },
      },
      // plaintext won't be generated in the `build-3` directory, because we didn't enable it
      {
        source: 'src/templates',
        destination: {
          path: 'build-3',
        }
      },
    ]
  }
}

Front Matter

Generate a plaintext version for a single Template by enabling it in its Front Matter:

src/templates/example.html

---
plaintext: true
---

<x-main>
  <!-- your email HTML... -->
</x-main>

A .txt file will be output at the same location with the compiled Template.

Permalink

If you're using the permalink Front Matter key in your Template, Maizzle will output the .txt file at that location:

src/templates/example.html

---
permalink: example/email.html
plaintext: true
---

<x-main>
  <!-- your email HTML... -->
</x-main>

For the Template above, example/email.txt will be generated.

Customization

By default, the plaintext generator in Maizzle uses most default options from string-strip-html, with this exception:

dumpLinkHrefsNearby: {
  enabled: true
},

This ensures URLs from anchors are actually output in the plaintext version.

You may use a plaintext object in your config.js to overwrite any of the defaults from string-strip-html.

config.js

module.exports = {
  build: {
    templates: {
      plaintext: {
        ignoreTags: [],
        onlyStripTags: [],
        stripTogetherWithTheirContents: ['script', 'style', 'xml', 'not-plaintext'],
        skipHtmlDecoding: false,
        trimOnlySpaces: false,
        dumpLinkHrefsNearby: {
          enabled: false,
          putOnNewLine: false,
          wrapHeads: '',
          wrapTails: ''
        },
        cb: null,
      },
    },
  },
}

With the config above, Maizzle will output plaintext versions for all Templates.

Front Matter override

Using plaintext: true like in the Front Matter example will override your plaintext config object if you have it defined in config.js like above.

If you need to control string-strip-html options when generating plaintext for a single Template, you need to use enabled: true.

You basically add the options object as shown above, but in Front Matter syntax:

---
plaintext:
  dumpLinkHrefsNearby:
    enabled: true
    putOnNewLine: true,
    wrapHeads: '['
    wrapTails: ']'
---

<x-main>
  <a href="https://example.com">Click here</a>
</x-main>

That will output:

Click here

[https://example.com]

`<plaintext>` tag

You can output content only in the plaintext version, with the <plaintext> tag:

src/templates/example.html

---
plaintext: true
---

<x-main>
  This text shows in both the HTML and the plaintext versions.

  <plaintext>This will be output only in the plaintext version</plaintext>
</x-main>

`<not-plaintext>` tag

You may also discard content from the plaintext version while preserving it in the HTML, with the help of the <not-plaintext> tag:

src/templates/example.html

---
plaintext: true
---

<x-main>
  This text shows in both the HTML and the plaintext versions.

  <not-plaintext>
    <p>This paragraph will be output only in the HTML version</p>
  </not-plaintext>
</x-main>

API

You may render an HTML string to plaintext in your application with the help of the plaintext() method. The custom tags, like <plaintext>, are also supported.

app.js

const Maizzle = require('@maizzle/framework')

const {plaintext} = await Maizzle.plaintext(`<p>your html string</p>`)

// your html string

You can also pass a config object to this method:

app.js

const {plaintext} = await Maizzle.plaintext('html string', {
  plaintext: {
    // string-strip-html options
  }
})

The object that you pass here must contain a plaintext: {} key, as explained in the customization section above.
