Exclude sub directory from static files in express

express, node.js

Solution

You can add your own middleware. Here's what I did to exclude some folders:

app.use('/public', (req, res, next) => {
  if (env !== 'development') {
    var result = req.url.match(/^\/js\/(maps|src)\/.+\.js$/)
    if (result) {
      return res.status(403).end('403 Forbidden')
    }
  }
  next()
})
app.use('/public', express.static(path.join(__dirname, '/public')))

Problem

Is there any way to exclude sub directory from express static middleware in express 4.8.5. For example if I have : ``` app.use(express.static(__dirname + 'public')); ``` And my public directory is like this : ``` - public - css - images - scripts - index.html - exclude_me - scripts - views - index.html ``` So I need to exclude last sub directory and when user does : ``` GET /exclude_me ``` It should call my route rather than returning directory automatically. I can't just remove it from public dir because it depends on stuff inside it because public directory is angular application and exclude_me is another angular application that fetches scripts from /exclude_me/scripts AND from /public/scripts. I know it is little confusing but it is how it is and I cannot just remove it from public dir because it won't see public/scripts any more which are needed and I cannot leave it because I cannot authorize it then (all authorization is in public/scripts) If there is some smarter way to do this, feel free to let me know :)
