To get all files in a folder recursively, use the glob library.

Install it:

npm install glob

For example, to find all index.md files under content/post (at any depth):

• content/post/first/index.md
• content/post/second/index.md
• content/post/another/test/index.md

Example:

const glob = require('glob')

const root_folder = 'content/post'

glob(root_folder + '/**/index.md', (err, files) => {
  if (err) {
    console.log('Error', err)
  } else {
    console.log(files)
  }
})
