API documentation generator for hapi

Lead Maintainer: Nicolas Morel

Description

lout is a documentation generator for hapi servers, providing a human-readable guide for every endpoint using the route configuration. The module allows full customization of the output.

Live demo

You can find a live demo of lout using the unit tests routes. The routes are of course fake but you can get a grasp of what lout looks like given various inputs.

Usage

var Hapi = require('hapi');
var server = new Hapi.Server();

server.connection({ port: 80 });

server.register({ register: require('lout') }, function(err) {
});

server.start();

Usage before Hapi 8.x

var Hapi = require('hapi');
var server = new Hapi.Server(80);

server.pack.register({ plugin: require('lout') }, function() {
    server.start();
});

Usage before Hapi 7.x

var Hapi = require('hapi');
var server = new Hapi.Server(80);

server.route([{
    your routes...
}]);

server.pack.require('lout', function() {
    server.start();
});

Parameters

The following options are available when registering the plugin:

• 'engines' - an object where each key is a file extension (e.g. 'html', 'jade'), mapped to the npm module name (string) used for rendering the templates. Default is { html: 'handlebars' }.
• 'endpoint' - the path where the route will be registered. Default is /docs.
• 'basePath' - the absolute path to the templates folder. Default is the lout templates folder.
• 'cssPath' - the absolute path to the css folder. Default is the lout css folder. It must contain a style.css.
• 'helpersPath' - the absolute path to the helpers folder. Default is the lout helpers folder. This might need to be null if you change the basePath.
• 'partialsPath' - the absolute path to the partials folder. Default is the lout templates folder. This might need to be null if you change the basePath.
• 'auth' - the route configuration for authentication. Default is to disable auth.
• 'indexTemplate' - the name of the template file to contain docs main page. Default is 'index'.
• 'routeTemplate' - the name of the route template file. Default is 'route'.
• 'filterRoutes' - a function that receives a route object containing method and path and returns a boolean value to exclude routes.

Ignoring a route in documentation

If you want a specific route not to appear in lout's documentation, you have to set lout settings for this specific route to false.

Here is an example snippet of a route configuration :

{
  method: 'GET',
  path: '/myroute',
  config: {
    handler: [...],
    [...]
    plugins: {
      lout: false
    }
  }
}

If you want to exclude multiple routes using conditions, you can use filterRoutes when registering lout :

server.pack.register({
  plugin: require('lout'),
  options: {
    filterRoutes: function (route) {
      return route.method !== '*' && !/^\/private\//.test(route.path);
    }
  }
}, function() {
    server.start();
});
