hapi-to

This plugin gives you an API for generating URLs dynamically in hapi using route ids and optional parameters, so you don't need to hardcode them into your views. This helps a bunch if you change the path structure of your routes, or move them into prefixed plugins in the future.

##Features

• Let's you change paths without breaking existing links + redirects
• 100% test coverage
• Works with params (including wildcard, optional and multi-params)
• Configurable with options

##Install

To download and add to dependencies run npm install --save hapi-to

Register with a server like any other hapi plugin with server.register():

var Hapi = require('hapi');

var server= new Hapi.Server();
server.connection({ port: 8080 });

server.register(require('hapi-to'), function (err) {
    
    if (err) {
        throw err;
    }
    
    server.start();
});

After registering, hapi-to will decorate the hapi request object with a new method: request.to().

##API

request.to(id, params, options)

Returns a URL to a route

• id - required route id. Set when creating a route with the config.id property.
• params - request parameters where:
  • query - an optional object of query string key-values. Will be stringified using the Qs module.
  • params - an optional object of path parameters. Number given must match route path. Each parameter value can be a string or an array of strings (for multi params)
• options - additional options which affect how the URL is generated where:
  • rel - Whether to generate a relative URL. Can be true or false (default).
  • secure - a boolean or "match". If true the URL will be https, if false will be http. If "match" (the default) will match the x-forwarded-proto header or the current request's connection protocol (in that order).
  • host - string that sets the host in the URL. Default is to match the current request.

##Example

var Hapi = require('hapi');

var server = new Hapi.Server();
server.connection({ port: 8080 });

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

        var url = request.to('hello', {
            params: { thing: 'stitch', num: 'nine' },
            query: { page: '1' }
        });

        reply.redirect(url);
    }
}, {
    method: 'GET',
    path: '/multi',
    handler: function (request, reply) {

        var url = request.to('rick', {
            params: { multi: ['never', 'gonna', 'give', 'you', 'up'] }
        });

        reply.redirect(url);
    }
}, {
    method: 'GET',
    path: '/a/{thing}/in/{num}/saves/time',
    config: {
        id: 'hello',
        handler: function (request, reply) {

            reply('You got here!');
        }
    }
}, {
    method: 'GET',
    path: '/{multi*5}',
    config: {
        id: 'rick',
        handler: function (request, reply) {

            reply('You got here!');
        }
    }
}]);

server.register(require('hapi-to'), function (err) {
    
    server.start();
});

If you run the above example and navigate to http://localhost:8080/ you will be redirected to http://localhost:8080/a/stitch/in/nine/saves/time?page=1

If you navigate to http://localhost:8080/multi you will be redirected to http://localhost:8080/never/gonna/give/you/up
