    info: Finds all of the wizards that are available, sorted by hat size
    
  post: /wizard createWizard
    info: Gives birth to a new wizard setting their name & (optionally) hat size

Docs are rendered to index.html & spec.json in your output directory, which is docs by default. If there are compilation errors they are rendered instead.

Writing Docs

You write you doc specification in its own directory, which defaults to api/. There should be an info.yml in that directory which describes your api, it can have a name, description and template. The template refers to an npm package defining the api template, see Custom Templates.

Api Info

info.yml

name: Wizards Api
# template: my-custom-npm-template 
description: >
  A simple API for creating & managing those pesky wizards

Endpoint Versions

Ocelot expects each version of your api to be in its own directory inside your input directory, e.g. v1/ or 1.0.0/, but you can have a single version at the root if you want. Ocelot sees any directory with an endpoints.yml file in as an api version.

endpoints.yml

wizards:
  base: /wzrd
  name: Wizards
  endpoints:
  id: index
    method: get
    url: /list
    name: Fetch Wizards
    info: Looks for all wizards and sorts them by hat size
  post: /new create
    name: Create Wizard
    body:
      name: string - The name of the wizard

Above is an example of an endpoints file, at the top level you have your groups which are a set of endpoint definitions.

Group Definition

Field Info
name The name of the group
base optional – A base url for this group, relative to the version's base
endpoints The list of endpoint definitions

Endpoint Definition

An endpoint is a specific url & http method that performs some logic in your api and returns a response.

Field Info
id An identifier for the endpoint
method The http method to access the endpoint
url The url to access the endpoint, relative to the group
name The name of the endpoint
info optional – A longer description of the endpoint
responses optional – A list of Response Definition
params optional – The url parameters e.g. /find/:id, an Argument Definition
query optional – The query parameters e.g. ?key=val, an Argument Definition
body optional – The json/form body parameters, an Argument Definition
Endpoint Shorthand

As seen at the very top, you can use the endpoint shorthand which defines the method, url & id in one go. The equivalent of the previous example would be:

endpoints:
  get: /list index
    name: Fetch Wizards
    info: Looks for all wizards and sorts them by hat size

Argument Definition

An argument definition is a YAML object with descriptions for a set of arguments. They key is the name of the argument and the value is a string definition containing the type, a dash (-) and the description. If the key ends with a ?, it is marked as optional.

name: string - The name of the wizard
age?: number - An optional age of the wizard

Response Definition

200: Success index/success.json
404: Not Found index/failed.json

A response definition is an array of objects which describe potential responses that the endpoint can return. It is in three parts, the key is the http status code, the first part is the human-friendly name and the last is the body, a reference to a file with an example json response in.

  • name is a friendly name of this response
  • status is the http status code this response comes with
  • body is a reference to a file which contains the example body (a json file)

To look for the body it will look look in data/ directory relative to your endpoints.yml file.

Version Info

When writing an endpoints.yml file, you can optionally define a version block at the top which defines meta information about this version of your api.

version: 0.0.1
base: /
groups:
  - wizards
  - witches
  - misc
---
wizards:
  # An endpoint group ... 

Version Block

Field Info
version The name of this version
base optional – The base url for this version, all endpoints will be under this
groups optional - The order of the endpoint groups in this version, an array of strings

Custom templates

A template is an npm package used to render an api definition using pug. The package should have a template/ directory which should contain:

  • info.yml – A file containing info about the template
  • index.pug – A pug template to render the api definition
  • error.pug – A pug template to render errors or warnings

info.yml

name: Custom Template
version: 0.1.2
link: https://example.com
 
assets:
- js
- css
- img
Field Info
name The name of the template
version The version of the template
link A link to the template's author
assets optional – A list of directories that will be copied into the compiled result

For more info, see the default template. There is also the spec.json, which is created along side your index.html, which is used to render the docs.
