Creating Swagger files is hard. This makes it easier.

Made by ReadMe! Need great hosting for your API? Check us out!

npm install oai -g

Go to a directory with your API, and type:

oai init

It will walk you through how to document your API with Open API Initiave.

Rather than trying to juggle one gigantic repo, oai uses something called swagger-inline. It lets you include a little swagger snippet in a comment above your code, and collects them all together into one Swagger file:

```javascript
/*
 * @api [get] /pet/{petId}
 * description: "Returns all pets from the system that the user has access to"
 * parameters:
 *   - (path) petId=hi* {String} The pet ID
 *   - (query) limit {Integer:int32} The number of resources to return
*/
route.get("/pet/:petId", pet.show);
```

You need to start with @api [method] path, but everything below it is a valid Swagger Path Definition.

You can also do inline parameters, which are shorthand for parameters. They aren't valid Swagger, however Swagger Inline knows how to compile them:

- (in) name=default\* {type:format} Description

Hosting Swagger files is hard! So, we have an online component that hosts your Swagger file for you. Just type the following to get a URL:

oai host

This will upload your Swagger file and give you a URL you can use.
