This is a OpenAPI (aka Swagger) plug-in for HAPI When installed it will self document the API interface in a project.
Release Notes for v9.0.x which only supports hapi v17 and above. Note: For hapi versions below v17, you must use versions v7.x.x of this module.
You can add the module to your HAPI using npm:
$ npm install hapi-swagger --save
If you want to view the documentation from your API you will also need to install the inert
and vision
plugs-ins which support templates and static
content serving.
$ npm install inert --save
$ npm install vision --save
In your HAPI apps main JavaScript file add the following code to created a HAPI server
object. You will also add the routes for you API as describe on hapijs.com site.
const Hapi = require('hapi');
const Inert = require('inert');
const Vision = require('vision');
const HapiSwagger = require('hapi-swagger');
const Pack = require('./package');
(async () => {
const server = await new Hapi.Server({
host: 'localhost',
port: 3000,
});
const swaggerOptions = {
info: {
title: 'Test API Documentation',
version: Pack.version,
},
};
await server.register([
Inert,
Vision,
{
plugin: HapiSwagger,
options: swaggerOptions
}
]);
try {
await server.start();
console.log('Server running at:', server.info.uri);
} catch(err) {
console.log(err);
}
server.route(Routes);
})();
As a project may be a mixture of web pages and API endpoints you need to tag the routes you wish Swagger to
document. Simply add the tags: ['api']
property to the route object for any endpoint you want documenting.
You can even specify more tags and then later generate tag-specific documentation. If you specify
tags: ['api', 'foo']
, you can later use /documentation?tags=foo
to load the documentation on the
HTML page (see next section).
{
method: 'GET',
path: '/todo/{id}/',
config: {
handler: handlers.getToDo,
description: 'Get todo',
notes: 'Returns a todo item by the id passed in the path',
tags: ['api'], // ADD THIS TAG
validate: {
params: {
id : Joi.number()
.required()
.description('the id for the todo item'),
}
}
},
}
Once you have tagged your routes start the application. The plugin adds a page into your site with the route /documentation
,
so the the full URL for the above options would be http://localhost:3000/documentation
.

I would like to thank all that have contributed to the project over the last couple of years. This is a hard project to maintain, getting HAPI to work with Swagger is like putting a round plug in a square hole. Without the help of others it would not be possible.
