Multiple Hooks for Fast-Gateway

Thought

The other day I was consuming fast-gateway and I came across use-cases to support multiple hooks

How to use?

• import this package in your fast-gateway application
• create hooks functions
  • you can now import { onResponseHook } and use typeof onResponseHook to ensure strict typings
• in the config for fast-gateway in the Hooks section

import { fgMultipleHooks }  from 'fg-multiple-hooks'; // Typescript
const { fgMultipleHooks } = require('fg-multiple-hooks); // Javascript
hooks: {
    onRequest: (req, res) => fgMultipleHooks.onRequestHooks(req, res, hook1, hook2),
    onResponse: (req, res, stream) => fgMultipleHooks.onResponseHooks(req, res, stream, useDefaultHook, hook1, hook2)
}

Other Notes

• use as many hooks as you please

OnRequestHook

• Each hookFunction should return a boolean, which if returned as true will abort the request

OnResponseHook

• Each hookFunction should return a boolean, which if returned as true will abort the request
• Each hookFunction is capable of handling manipulation of stream (response from service to gateway)
• you can pass a boolean to define if the chain of hooks should add the default hook, handling basic scenario(copied from 'fast-gateway'), at the end
