## Installation
You can add the module to your Hapi using npm:
```bash
> npm install hapi-swagger --save
```
**hapi-swagger** no longer bundles `joi` to fix [#648](https://github.com/hapi-swagger/hapi-swagger/issues/648). Install **hapi-swagger** with peer dependencies using:
```bash
npx install-peerdeps hapi-swagger
```
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.
```bash
> npm install @hapi/inert --save
> npm install @hapi/vision --save
```
## Documentation
- [Options Reference](optionsreference.md)
- [Usage Guide](usageguide.md)
## Quick start
In your Hapi apps please check the main JavaScript file and add the following code to already created a Hapi `server` object.
You will also add the routes for you API as describe on [hapi website](https://hapi.dev/).
```Javascript
const Hapi = require('@hapi/hapi');
const Inert = require('@hapi/inert');
const Vision = require('@hapi/vision');
const HapiSwagger = require('hapi-swagger');
const Pack = require('./package');
(async () => {
const server = Hapi.server({
port: 3000,
host: 'localhost'
});
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);
})();
```
### Tagging your API 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).
```Javascript
{
method: 'GET',
path: '/todo/{id}/',
options: {
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: Joi.object({
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`.
### Typescript
**hapi-swagger** exports its own typescript definition file that can be used when registering the plugin with **Hapi**. See example below:
#### Install Typescript Definition Files
```sh
npm i @types/hapi__hapi @types/hapi__inert @types/hapi__joi @types/hapi__vision @types/node hapi-swagger --save-dev
```
#### Register Plugin with Typescript
```typescript
import * as Hapi from '@hapi/hapi';
import * as HapiSwagger from 'hapi-swagger';
// code omitted for brevity
const swaggerOptions: HapiSwagger.RegisterOptions = {
info: {
title: 'Test API Documentation'
}
};
const plugins: Array> = [
{
plugin: Inert
},
{
plugin: Vision
},
{
plugin: HapiSwagger,
options: swaggerOptions
}
];
await server.register(plugins);
```

## Thanks
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.
