Express: Request parameters

I mentioned how the Request object holds all the HTTP request information.

These are the main properties you’ll likely use:

.appholds a reference to the Express app object
.baseUrlthe base path on which the app responds
.bodycontains the data submitted in the request body (must be parsed and populated manually before you can access it)
.cookiescontains the cookies sent by the request (needs the cookie-parser middleware)
.hostnamethe hostname as defined in the Host HTTP header value
.ipthe client IP
.methodthe HTTP method used
.paramsthe route named parameters
.paththe URL path
.protocolthe request protocol
.queryan object containing all the query strings used in the request
.securetrue if the request is secure (uses HTTPS)
.signedCookiescontains the signed cookies sent by the request (needs the cookie-parser middleware)
.xhrtrue if the request is an XMLHttpRequest
