如何在'sanitize-html'中的锚标记中设置或覆盖target =“_ blank”？

Question

I am using sanitize-html in my project. Say suppose I get a mail which has anchor tag, something like this: this is to test something <a href="https://www.google.com/">open google</a>

This mail appears in my mail box like this : this is to test something open google

Which opens google.com in the same tab. But I need to open in new tab . Here is my code.

__html = sanitizeHTML(children, {
        allowedTags: sanitizeHTML.defaults.allowedTags.concat([ 'img' ]),
        allowedAttributes: {
          '*': [ 'href', 'align', 'alt', 'center', 'bgcolor', 'style', 'width' ],
          'img': ['src'],
          'a' : ['target'] 
        },
       }

Here I want to set or override target = "_blank" . How to achieve that in sanitize-html ?

Unfortunately I could not find a tag for sanitize-html.

According to READ.MD/doc and your problem description, something like:

__html = sanitizeHTML(children, {
    ...,
    transformTags: {
      'a': function(tagName, attribs) {// simpleTransform also possible...
       return {
        tagName: 'a',//tagName
        attribs: {
            target: '_blank',
            href:   '*'
        }
    };
}

...should do it.

EDIT:

A better solution preserving the current (allowed!) attributes:

....
 transformTags: {
   'a': sanitizeHtml.simpleTransform('a', {target: '_blank'})
 }
