hapi-route-hierarchy

Hapi plugin that automatically sets up your routes based on your directory hierarchy.

What is this?

The purpose of this plugin is to allow intuitive route setup by basing routes on your directory structure. For example, imagine you have a Hapi project with this folder structure:

my_hapi_project
│   server.js
│
└───routes
    │   login.js
    │
    └───users
        │   group_a.js
        │   group_b.js

Assume that server.js simply starts the Hapi server, after registering the plugin like this:

server.register(
    {
        plugin: require( 'hapi-route-hierarchy' ),
        options: {
            root: __dirname + '/routes',
            glob_pattern: '**/*.js'
        }
    }, ( err ) => {
        // Start the server...
    }
)

All the files under /routes include the data for all the routes. So for example, /routes/login.js might look like this:

module.exports = {
    method: 'GET',
    path: '/login',
    handler: function( request, h ) {
        return h.response( 'You have been authenticated!' );
    }
};

This will result in a route at /login, which is rather boring, but what if we put something similar in /routes/users/group_a.js:

module.exports = {
    method: 'GET',
    path: '/group_a',
    handler: function( request, h ) {
        return h.response( 'Here is a list of all users in group A!' );
    }
};

This would result in a route at /users/group_a.

In this way you can easily keep your routes organized by ensuring they always match your directory structure.

Plugin Options

root

• REQUIRED

  • Relative path from process.cwd()
  • Absolute path

glob_pattern

• REQUIRED
• Type: string
• Description: The glob pattern to use to determine which files should be loaded as route files.

glob_options

• Type: object
• Description: Options that will be passed to the glob NPM module. Here is a full list of available options.

Route files

The route files can define route data in 3 different ways:

Object

module.exports = {
    method: 'GET',
    path: '/some_path',
    handler: function( request, h ) {
        // Do something...
    }
};

Array

module.exports = [
    {
        method: 'GET',
        path: '/some_path',
        handler: function( request, h ) {
            // Do something...
        }
    },
    {
        method: 'POST',
        path: '/some_other_path',
        handler: function( request, h ) {
            // Do something...
        }
    }
];

Function

Note that this variation allows you to access the Hapi server object

module.exports = function( server ){
    return {
        method: 'GET',
        path: '/some_path',
        handler: function( request, h ) {
            let some_fancy_plugin = request.server.plugins['some_fancy_plugin'];
            h.response( some_fancy_plugin.doFancyThings() );
        }
    };
};
