Express Routing & Connected API

Using Express Routing

Routing refers to how an application’s endpoints (URIs) respond to client requests
You define routing using methods of the Express app object that correspond to HTTP methods
The application “listens” for requests that match the specified route(s) and method(s), and when it detects a match, it calls the specified callback function
Route paths, in combination with a request method, define the endpoints at which requests can be made
- Route paths can be strings, string patterns, or regular expressions
  - The characters ?, +, *, and () are subsets of their regular expression counterparts
  - The hyphen (-) and the dot (.) are interpreted literally by string-based paths
