# fastify-oas
**NOTE**: OpenAPI 3 support finally [landed](https://github.com/fastify/fastify-swagger/pull/333) in "official" [fastify-swagger](https://github.com/fastify/fastify-swagger) module. Consider using it instead of this one, since it has better support for $ref in schemas.
This plugin is deprecated and no longer mainteined. Feel free to fork it and publish if needed.

[OpenAPI 3.0+ (OAS3)](https://swagger.io/docs/specification/about/) documentation generator for Fastify.
It uses the schemas you declare in your routes to generate an OpenAPI (swagger) compliant doc.
This plugin based on [fastify-swagger](https://github.com/fastify/fastify-swagger/) that generates swagger 2.0 docs.
This plugin designed in such way to be compatible with it's predcessor and in most cases if you already use `fastify-swagger` you may just replace it with current plugin and it should work.

## Fastify support
- v0.X.X - v1.X.X - supports fastify v1.X.X
- v2.X.X - will support fastify v2.X.X*
Currently in Fastify v2.12.0 there's regression bug that breakes this exenstion for many users. So for now this extension doesn't support fastify 2.12.0. Cause it was cause by fastify minor change in order to preven issues this library will throw an error when you'll try to use it with that fastify version.
In order to use it, you can either lock your fastify at 2.11.0 or fastify-oas at 2.5.0 (but there are no gaurantee that it will work correctly).
## Installation
```sh
npm i fastify-oas --save
```
[Back to top](#toc)
## Features and requirements
* Supports OpenAPI 3+.
* Supports [fastify-swagger](https://github.com/fastify/fastify-swagger/) module configs.
* Supports swagger 2.0 fastify schemas.
* Supports fastify named schemas convertion to swaagger/openapi models.
---
* Requires fastify `>=1.9.0`.
* Node.js `>=8.9.0`.
NOTE: If you need to generate fastify routes from your swagger document - please refer to plugins in [See also](#see-also) like fastify-swaggergen or fastify-openapi-glue.
[Back to top](#toc)
## Usage
Add it to your project like regular fastify plugin. Use `register` method and pass it swagger options, then call the api constructor.
```js
const fastify = require('fastify');
const oas = require('fastify-oas');
const app = fastify();
app.register(oas, {
routePrefix: '/documentation',
swagger: {
info: {
title: 'Test openapi',
description: 'testing the fastify swagger api',
version: '0.1.0',
},
externalDocs: {
url: 'https://swagger.io',
description: 'Find more info here',
},
consumes: ['application/json'],
produces: ['application/json'],
},
exposeRoute: true
});
// put some routes and schemas
app.ready(err => {
if (err) throw err;
app.oas();
});
```
Please note, the schema format for Fastify routes is [JSONSchema](https://github.com/fastify/fastify/blob/v2.13.0/docs/Routes.md#routes-option) and you may encounter some differences in the format for route spec vs. output OpenAPI spec.
This plugin includes handling around a few of these differences.
One such case is the `example` or `examples` keywords:
```js
fastify.route({
method: 'POST',
url: '/',
schema: {
body: {
type: 'object',
description: 'an object',
examples: [
{
name: 'Object Sample',
summary: 'an example',
value: {a: 'payload'},
}
],
properties: {
a: {type: 'string', description: 'your payload'}
}
}
},
handler: // ...
})
```
Which produces a spec similar to:
```json
{
...
"content": {
"application/json": {
"examples": {
"Object Sample": {
"summary": "an example",
"value": {
"a": "payload"
}
}
},
"schema": {
"type": "object",
"properties": {
"a": {
"type": "string",
"description": "your payload"
}
}
}
}
}
}
```
(in this case, the name property is extracted as the examples key)

### Docs
See [Docs](/docs/README.md) for more details on the TypeScript types that you may use when working with OpenAPI spec.
### Plugin options
| parameter | type | description | default |
| -------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------ | ---------------- |
| `routePrefix` | String | Documentation endpoint | `/documentation` |
| `exposeRoute` | Boolean|Object** | If `true` the plugin will expose the documentation with the following apis: `/`, `//json`, `//yaml` | `false` |
| `addModels` | Boolean | If `true` adds fastify schemas as openapi models* | `false` |
| `openapi` | String | Openapi version | '3.0.0' |
| `yaml` | Boolean | If `true` returns yaml instead of json | `false` |
| `hideUntagged` | Boolean | If `true` remove routes without tags in schema from resulting swagger file | `false` |
| `swagger` | Object | Swagger object except paths | `{}` |
Note (*): Fastify-oas plugin gather all schemas, so you should ensure that all of them under current and nested scopes have unique names.
Note (**): see [Expose route options](/docs/interfaces/fastifyoas.exposeoptions.md)
[Back to top](#toc)
### Additional schema options
In order to remove some endpoints from Swagger/OpenAPI document you may add `{hide: true}` option to route schema.
```js
const fastify = require('fastify')()
fastify.get('/some-secrete-route/:id', {
schema: {
hide: true,
params: {
type: 'object',
properties: {
id: {
type: 'string',
description: 'user id'
}
}
},
response: {
201: {
description: 'Successful response',
type: 'object',
properties: {
hello: { type: 'string' }
}
}
},
}
}, (req, reply) => {})
```
[Back to top](#toc)
### OpenAPI
Unlike regular OpenAPI spec you'll still need some options from swagger 2.0.
```js
const fastify = require('fastify');
const oas = require('fastify-oas');
const app = fastify();
app.register(oas, {
routePrefix: '/documentation',
swagger: {
info: {
title: 'Test openapi',
description: 'testing the fastify swagger api',
version: '0.1.0',
},
externalDocs: {
url: 'https://swagger.io',
description: 'Find more info here',
},
consumes: ['application/json'], // app-wide default media-type
produces: ['application/json'], // app-wide default media-type
servers: [{
url: 'http://api.example.com/v1',
description: 'Optional server description, e.g. Main (production) server',
}],
components: {
// see https://github.com/OAI/OpenAPI-Specification/blob/OpenAPI.next/versions/3.0.0.md#componentsObject for more options
securitySchemes: {
BasicAuth: {
type: 'http',
scheme: 'basic',
},
},
},
},
});
```

### Swagger 2.0
This will not generate swagger 2.0 docs. It will generate openapi 3.0 docs, but from swagger 2.0 (and fastify-swagger) compatible configuration.
It will allow easily migrate from fastify-swagger.
The example below is taken from fastify-swagger repo to show the differences .
```js
const fastify = require('fastify')()
// before: fastify.register(require('fastify-swagger'), {
fastify.register(require('fastify-oas'), { // after
routePrefix: '/documentation',
swagger: {
info: {
title: 'Test swagger',
description: 'testing the fastify swagger api',
version: '0.1.0'
},
externalDocs: {
url: 'https://swagger.io',
description: 'Find more info here'
},
host: 'localhost',
schemes: ['http'],
consumes: ['application/json'],
produces: ['application/json'],
tags: [
{ name: 'user', description: 'User related end-points' },
{ name: 'code', description: 'Code related end-points' }
],
securityDefinitions: {
apiKey: {
type: 'apiKey',
name: 'apiKey',
in: 'header'
}
}
}
})
fastify.put('/some-route/:id', {
schema: {
description: 'post some data',
tags: ['user', 'code'],
summary: 'qwerty',
params: {
type: 'object',
properties: {
id: {
type: 'string',
description: 'user id'
}
}
},
body: {
type: 'object',
properties: {
hello: { type: 'string' },
obj: {
type: 'object',
properties: {
some: { type: 'string' }
}
}
}
},
response: {
201: {
description: 'Successful response',
type: 'object',
properties: {
hello: { type: 'string' }
}
}
},
security: [
{
"api_key": []
}
]
}
}, (req, reply) => {})
fastify.ready(err => {
if (err) throw err
fastify.oas()
})
```

## Development
In order to start development run:
```sh
npm i
npm run prepare
```
So that [swagger-ui](https://github.com/swagger-api/swagger-ui) static folder will be generated for you.
