Introduction

NestJS Referers is a simple package that implements decorator based validation for the referer header of incoming HTTP requests. The adopted syntax for specifying allowed URL's was based on Algolia's example.

A few examples:

• https://algolia.com/* will restrict access to all referers starting with https://algolia.com
• *.algolia.com will restrict access to all referers ending with .algolia.com
• If you want to allow access for the full domain algolia.com, you can use algolia.com/

Regarding security, you should know that referers can be easily spoofed like any other HTTP header, so you should not rely on this technique alone for securing requests.

Installation

npm i nestjs-referers --save
