ensureSymlink(srcpath, dstpath, [type, callback])

Ensures that the symlink exists. If the directory structure does not exist, it is created.

• srcpath <String>
• dstpath <String>
• type <String>
• callback <Function>

Example:

const fs = require('fs-extra')

const srcpath = '/tmp/file.txt'
const dstpath = '/tmp/this/path/does/not/exist/file.txt'
fs.ensureSymlink(srcpath, dstpath, err => {
  console.log(err) // => null
  // symlink has now been created, including the directory it is to be placed in
})

// With Promises:
fs.ensureSymlink(srcpath, dstpath)
.then(() => {
  console.log('success!')
})
.catch(err => {
  console.error(err)
})
