Express utilities

Express utility functions

The pillarjs GitHub organization contains a number of modules for utility functions that may be generally useful.

Utility modules	설명

csrf	Contains the logic behind CSRF token creation and verification. Use this module to create custom CSRF middleware.
finalhandler	Function to invoke as the final step to respond to HTTP request.
parseurl	Parse a URL with caching.
path-to-regexp	Turn an Express-style path string such as ``/user/:name` into a regular expression.
resolve-path	Resolves a relative path against a root path with validation.
router	Simple middleware-style router.
send	Library for streaming files as a HTTP response, with support for partial responses (ranges), conditional-GET negotiation, and granular events.
