Paid Feature

This feature is only available in paid plans. Learn More

The Audit tab flags common issues so you can address them before finishing your email or page design. It currently looks for accessibility checks so you can identify and fix common issues during the design process. It addresses:

  • Missing alternate text for images
  • Missing links in buttons or menus
  • Missing image URLs

As an added bonus, by using the Audit tab and learning from the issues it flags, you can become more practiced and aware of these considerations so they’re part of your design and development workflow instead of an afterthought.

Enable / Disable

You can enable or disable this feature.

unlayer.init({
  features: {
    audit: true
  }
})

Custom Validators

If you want to run the content for other types of issues, you can create custom validators.

Global Validator

A global validator can be used to identify general design issues. For example, if you want to run and analyze the content for potential spamminess.

unlayer.setValidator(function (data) {
  const { html, design, defaultErrors } = data;
  
  return [
    {
      id: 'DESIGN_CUSTOM_ERROR',
      icon: 'fa-smile',
      severity: 'WARNING',
      title: 'This is a custom error',
      description:
        'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce pretium non lectus venenatis lacinia. Fusce vitae venenatis nibh. Sed laoreet ornare lorem, a convallis nibh suscipit eu. Ut dictum commodo velit vitae interdum.',
    },
  ].concat(defaultErrors);
});

Each error needs to have the following parameters.

NameDescription
idA unique ID for the error type
iconIcon that users see in the errors tab. The value can be class name of any fontawesome icon, or a URL for your icon's image
severityERROR or WARNING
titleTitle of the error message
descriptionDescription of the error message

Tool Validator

Similar to the global validator, you can also create custom validators for different tools. This can be done for built-in tools, as well as custom tools, using 'custom#tool_name' as the first argument. These validators can check and validate different values of the tools' properties.

Here's an example of attaching a validator to the button tool.

unlayer.setToolValidator('button', function(data) {
  const { defaultErrors, values } = data;

  return [
    {
      id: 'CUSTOM_ERROR',
      icon: 'fa-smile',
      severity: 'WARNING',
      title: 'This is a custom button error',
      description: `Lorem ipsum dolor sit amet ${values?.text}.`,
    },
  ].concat(defaultErrors);
});

Translations (i18n) for Validators

The title and description for each error can include translated text to keep it i18n compliant. You can read more about our localization.

unlayer.init({
  translations: {
    en: {
      custom_translation_title: 'This is a custom title',
      custom_translation_desc: 'This is a custom description.',
    },
  },
});

unlayer.setToolValidator('button', function (data) {
  return [
    {
      id: 'CUSTOM_ERROR',
      icon: 'fa-smile',
      severity: 'WARNING',
      title: 'custom_translation_title',
      description: 'custom_translation_desc',
    },
  ];
});

Check Status

You can check if there are any active errors or warnings in the design by using the following method.

unlayer.audit(function(data) {
  console.log(data);
  
  // {
  //   status: "PASS",
  //   errors: [],
  // }

  // {
  //   status: "FAIL",
  //   errors: [{...}],
  // }
});

Spam Example

Here's an async example where you can use an external API to check your content for spam.

unlayer.setValidator(async (data) => {
  const { html, design, defaultErrors } = data
  const errors = []

  // Check HTML for spamminess using a third-party API
  const isSpammy = await isHtmlSpammy(html);

  if (isSpammy) {
    errors.push(
      { 
        id: 'SPAM_ERROR',
        icon: 'fa-image',
        severity: 'WARNING',
        title: 'Content is Spammy',
        description:
          'The content seems to be spammy. Fix your content.',
      }
    );
  }

  return errors.concat(defaultErrors);
});
