// completition works here
const jsMime = mime.mimeToInfo['application/javascript']

// mime to content encoding
console.log(mime.mimeToContentEncoding(jsMime))
// "application/javascript; charset=utf-8"

// find mime for file
const maybeMime = mime.findMimeForFile('./static/index.html')
console.log(maybeMime)
// text/html
console.log(mime.getMimeInfo(maybeMime))
// {
//   source: 'iana',
