Hapi-405-Routes

Plugin for Hapi.js to include 405 Method Not Allowed Responses on routes for a given set of methods.

Overview

This plugin registers additional routes with your hapi service for routes with specific methods not implemented.

Say you have a farming web service has an api with only 2 routes:

GET /farm/goats // route which retrieves data about all goats on the farm.

POST /farm/goats // route which allows for creation of additional goats.

By default, hapi responds with a 404 if there is not route/method match registered with the service. If a user were to request OPTIONS /farm/goats they would get a 404 response.

This plugin builds additional routes based on the route paths already implemented which will respond with a 405 status code. Using this plugin and requesting OPTIONS /farm/goats will respond with a 405 Method Not Allowed.

Additionally the 405 routes can be configured to respond with an allow header specifying which methods are allowed for the requested route path. See [options](# Options) below.

Installing

This plugin is available through an npm module.

npm install hapi-405-routes

Usage

This plugin must be registered after the implemented routes have already been registered with the service.

// my service routes
server.route(routes);

// this 405 route plugin
server.register([
    {
        register: require('hapi-405-routes'),
        options: {
            methodsToSupport: ['GET', 'DELETE', 'PATCH', 'POST', 'OPTIONS'],
            setAllowHeader: true,
            log: true
        }
    }
]);
