PCF Tools

Assemble API Blueprint specs with concatenation, templating, and inheritance.

Installation

sudo npm install -g pcf-tools

build command

pcf build path/to/specs path/to/output.md

Loads spec.json at the root of the folder, which looks like this:

{
  "name": "Prolific Store",
  "inherit": "node_modules/pcf-specs",
  "version": "1.1.0",
  "features": [
    "overview",
    "endpoints/products",
    "endpoints/cart",
    "endpoints/checkout",
    "models/product",
    "models/cartItem"
  ],
  "excludeEndpoints": {
    "/products/{id}/reviews": [
      "POST"
    ],
    "/checkout/gift-cards": true
  }
}

A rundown of each option:

name - The name of the API. inherit (optional) - Path to specs to inherit from. See "Spec Inheritance" to learn how specs are merged. version - Semantic versioning of the specs (not the API). features - Concatenates each markdown file at the given path within the spec folder (with .md omitted). excludeEndpoints (optional) - A map of endpoint paths to omit. If the value is an array, it will only omit those methods. If it is true, it will omit all methods for that endpoint.

Setting Up The File Structure

First we'll lay out a basic example, then explain the purpose of each directory and file.

spec/
  spec.json
  package.json
  Makefile
  overview.md
  node_modules/
  endpoints/
    products.md
  examples/
    product.json
  schemas/
    product.json
  models/
    product.md
  headers/
    session.js

package.json

If you plan on extending a public base spec, like pcf-specs, initiate an npm package.json file:

npm init

Then install the spec:

npm install pcf-specs

This will allow you to lock your spec to a specific version of the parent one using the package.json file.

overview.md

The introductory part of the spec, including title:

# Google Maps API

This is the Google Maps API. Enjoy!

endpoints/

This holds the markdown files that will be concatenated together. They also allow you to use Handlebars templating, providing several helpers:

# Group Products
These are the endpoints regarding products.

## Product [/products/{id}]

### Get Product [GET]
Gets the full product model for the given id.

+ Parameters

  + id (required, string, `12345`) ... The id of the product.

+ Response 200 (application/json; charset=utf-8)

  + Body

            {{example 'product'}}

  + Schema

            {{schema 'product'}}

The example helper inserts the JSON from examples/product.json, while schema inserts the JSON from schemas/product.json.

examples/

Holds example JSON bodies to be returned by endpoints. Here is an example that extends a parent one. Notice you can also use templating within a JSON file as well:

{
  "__exclude": ["rating"],
  "reviews": "{{example 'reviewCollection'}}",
  "materials": [
    "cotton",
    "polyester"
  ]
}

See JSON File Features to learn about __exclude and other functions.

schemas/

Includes body schemas to be included in endpoint files.

models/

Includes markdown files that describe each model. These are typically appended at the end of the blueprint.

# Group Product Model

Description of the product model.

{{schema 'product'}}

Headers

Includes flat JSON files representing names and example values of headers.

{
  "sessionId": "a8d8f9ea108382374"
}

JSON File Features

You can manipulate JSON structures using special keys that act as functions.

"__exclude": ["key1", "key2"] - Omits specified keys. Used to suppress inherited keys from parent specs. Can be at any level in the JSON object. "__include": ["key3", "key4"] - Only uses specified keys. Can be used anywhere in JSON object. Takes precedence over __exclude. "__inherits": "examples/shortProduct.json" - Merges this object into specified object. "key": "{{example 'addressCollection'}}" - Imports specified JSON object.
