Content excerpt support

Describe the solution you’d like

Please provide a way to fetch plain content body texts (not the body object of the current fetching result), in order to display excerpt on pages such as content list view. Feature like Content Excerpt of VuePress would be awesome.

Describe alternatives you’ve considered

Having <nuxt-content> prop for displaying excerpt and other selected content properties would be useful too.

@benjamincanac Sorry for misunderstanding. On the latest commit I succeeded in retrieving only plain excerpt texts using remark plugin properly and retext-stringify plugin additionally.

import remark from 'remark'
import remarkExcerpt from 'remark-excerpt'
import retextStringify from 'retext-stringify'

...
hooks: {
  'content:file:beforeInsert': async (document) => {
    if (document.extension === '.md') {
      const processed = await remark()
        .use(remarkExcerpt)
        .use(retextStringify)
        .process(document.text)
      document.excerpt = processed.contents
    }
  }
}

This workaround should be enough until it is officially supported in a more integrated way. Thank you.

@imlautaro This has been implemented in the core of @nuxt/content since then: https://content.nuxtjs.org/writing#excerpt.
