() Function - GeeksforGeeks

Now suppose you wanted to ignore logging requests for static files, but to continue logging routes and middleware defined after logger(). You would simply move the call to () to the top, before adding the logger middleware:

Express cors middleware - Express - web

Sets the Content-Type HTTP header to the MIME type as determined by () for the specified type. If type contains the “/” character, then it sets the Content-Type to type.

Serving static files in Express - Express - web

Some template engines do not follow this convention. The library maps Node template engines to follow this convention, so they work seamlessly with Express.

This property is an object containing properties mapped to the named route “parameters”. For example, if you have the route /user/:name , then the “name” property is available as . This object defaults to {}.

Returns an instance of a single route, which you can then use to handle HTTP verbs with optional middleware. Use () to avoid duplicate route names (and thus typo errors).

In Express , the * character in regular expressions is not interpreted in the usual way. As a workaround, use {5,} instead of *. This will likely be fixed in Express 5.

This property is an object containing a property for each query string parameter in the route. When query parser is set to disabled, it is an empty object {} , otherwise it is the result of the configured query parser.
