Running a Sails.js application results in the automatic addition of the HTTP header
X-Powered-By: "Sails <sailsjs.org>"Is there a way to prevent or modify this header?
Absolutely, it is definitely achievable.
To achieve this, you must deactivate the middleware in Sails known as poweredBy and ensure that Express.js server does not include its own header.
To accomplish this task, simply modify your configuration file config/http.js as follows:
module.exports.http = {
middleware: {
disablePoweredBy: function(request, response, next) {
var expressApp = sails.hooks.http.app;
expressApp.disable('x-powered-by');
// response.set('X-Powered-By', 'One Thousand Hamsters');
next();
},
order: [
// ...
// 'poweredBy',
'disablePoweredBy',
// ...
]
}
};
In this code snippet, we are fetching an instance of Express Application from Sails hooks and using its disable() method to set the configuration parameter x-powered-by to a value of false, thereby preventing the header from being displayed.
To activate this custom middleware, add it to the order array by replacing the existing poweredBy middleware with disablePoweredBy.
If desired, uncommenting the response.set() method allows you to specify your preferred header value.
Make changes to your config/http.js file by setting the poweredBy option to false:
module.exports.http = {
middleware: {
poweredBy: false
}
}
There is no need to manually disable the express X-Powered-By header since Sails will take care of it automatically. More information can be found here.
Instead of creating a new middleware, you have the option to override the poweredBy middleware in Sails.js. An example of how to do this is:
module.exports.http = {
middleware: {
poweredBy: function (req, res, next) {
// Uncomment the line below if you want to replace with your own
// res.set('X-Powered-By', "Some Great Company");
return next();
}
}
}
