What is caseless?

The caseless npm package is a utility for managing HTTP headers in a case-insensitive manner. It allows you to get, set, and delete headers on an object without worrying about the case sensitivity of the header names.

What are caseless's main functionalities?

Setting headers

This feature allows you to set headers on an object. The headers are managed in a case-insensitive way, so setting 'A-Header' would overwrite 'a-header' if it already exists.

{"var caseless = require('caseless');\nvar headers = {};\nvar c = caseless(headers);\nc.set('a-Header', 'the value');\nconsole.log(headers); // Output will be { 'a-header': 'the value' }"}

Getting headers

This feature allows you to retrieve the value of headers regardless of the case of the header name you provide.

{"var caseless = require('caseless');\nvar headers = {'a-header': 'the value'};\nvar c = caseless(headers);\nconsole.log(c.get('A-Header')); // Output will be 'the value'"}

Checking if a header exists

This feature allows you to check if a header exists in the object, regardless of the case of the header name.

{"var caseless = require('caseless');\nvar headers = {'content-type': 'application/json'};\nvar c = caseless(headers);\nconsole.log(c.has('Content-Type')); // Output will be true"}

Deleting headers

This feature allows you to delete headers from the object. The deletion is case-insensitive.

{"var caseless = require('caseless');\nvar headers = {'content-type': 'application/json'};\nvar c = caseless(headers);\nc.delete('Content-Type');\nconsole.log(headers); // Output will be {}"}
