sails.js: how to disable etags

问题

I read this not very new post about disabling some things in sails.js. Specifically what I would like to try out is the disabling of etags.

Does anyone know how to disable that in sails.js (0.11.0)?

回答1:

You could disable it in the bootstap.js file:

// config/bootstrap.js
module.exports.bootstrap = function(cb) {

  // Add this line to access to the Express app and disable etags
  sails.hooks.http.app.disable('etag');

  // It's very important to trigger this callback method when you are finished
  // with the bootstrap!  (otherwise your server will never lift, since it's waiting on the bootstrap)
  cb();
};

The above answer is only for dynamic files. For static files, you must override the www middleware by adding this code to the config/https.js file

www: (function() {
  var flatFileMiddleware = require('serve-static')('.tmp/public', {
    maxAge: 31557600000,
    etag: false
  });

  return flatFileMiddleware;
})(),

The maxAge has to be there if you still want to set the cache-control header with an age. Also note that this will override the cache option in the same http.js file used to define that age.

For my purpose, I only wanted to remove the etags from the static files served up in the /min folder, which are the minified css and js files. So to do this I had to define a route in the routes.js file

'get /min/*': { 
  skipAssets: false,
  fn: [
    require('serve-static')('.tmp/public', {
      maxAge: process.env.NODE_ENV !== 'production' ? 0 : 31557600000,
      etag: false
    }),
  ]
}
