Express middleware to return 503 if server is too busy right now

express-toobusy

Keep your Express server responsive even under heavy load! This trivial middleware uses toobusy-js library which is doing all the magic. Express-toobusy is just a handy wrapper middleware for Express.

 
    app.use(require('express-toobusy'));
 

If you want to specify your own max lag value, use it like this:

 
    app.use(require('express-toobusy')(40));
 

For details on max lag meaning and default values refer to toobusy-js documentation.
