How to call Hapi Plugins for certain routes? - plugins

Question

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?

Answer 1

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
}
}
});
