const contentType = getType('html');

console.log(contentType);//text/html; charset=utf-8

mime-types

mime.lookup(path)

mime.lookup('json')             // 'application/json'
mime.lookup('.md')              // 'text/markdown'
mime.lookup('file.html')        // 'text/html'
mime.lookup('folder/file.js')   // 'application/javascript'
mime.lookup('folder/.htaccess') // false
 
mime.lookup('cats') // false

mime.contentType(type) 獲取完成的頭部

mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
mime.contentType('file.json') // 'application/json; charset=utf-8'
 
// from a full path
mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'

mime.extension(type) 獲取類型的默認擴展名

mime.extension('application/octet-stream') // 'bin'
