How to call Hapi Plugins for certain routes?

Im using Hapi 12.1.

Trying to figure out how to call certain extension points only on certain routes.

For example for : '/hello' I want to call three different extension points that work on the 'onRequest' step.

For: '/goodbye' I want to call a different extension point that works also on the 'onRequest' but is a different operation and a 'onPreAuth' step.

For: '/health' Dont call any extension points, and just drop into the handler straight away..

I have tried various ways to create a plugin, define the routes, and extension points. But it seems the the extension points are global, and dont only operation on the plugin's scoped routes.

What am I missing?

You have access to the path on your extension points, using request.route.path. With that, you can define what you want to run, depending on the path. Example:

server.ext('onPreAuth', function (request, reply) {

    switch(request.route.path) {
        case '/test1':
        case '/test2':
            // Do something

            break;
        case '/test3':
            // Do something else

            break;
    }

    reply.continue();
});

Alternatively, you can also make it dependent on the route configuration:

server.ext('onPreAuth', function (request, reply) {

    if(request.route.settings.plugins.runPreAuth) {
        // Do something

    }

    reply.continue();
});

Then, you just define in your route the configurations:

server.route({
    method: 'get',
    path: '/test1',
    handler: function(request, reply) {

        reply({result: 'ok'});
    },
    config: {
        plugins: {
            runPreAuth: true
        }
    }
});
