Swagger Snippet

Generates code snippets for given Swagger / Open API specification files.

This package takes as input a Swagger 2.0 / Open API specification. It translates the specification into an HTTP Archive 1.2 request object. It uses the HTTP Snippet library to generate code snippets for every API endpoint (URL path + HTTP method) defined in the specification in various languages & tools (cURL, Node, Python, Ruby, Java, Go, C#...).

Installation

npm i --save swagger-snippet

Build Swagger Snippet (for use in browser)

Clone the Swagger Snippet repository. Install required dependencies:

npm i

Build a minified version of Swagger Snippet (swaggersnippet.min.js):

npm run build

Usage

As a module

let SwaggerSnippet = require('swagger-snippet')

// define input:
var swagger = ... // a Swagger / Open API specification
var targets = ['node_unirest', 'c'] // array of targets for code snippets. See list below...

try {
  // either, get snippets for ALL endpoints:
  var results = SwaggerSnippet.getSwaggerSnippets(swagger, targets) // results is now array of snippets, see "Output" below.

  // ...or, get snippets for a single endpoint:
  var results2 = SwaggerSnippet.getEndpointSnippets(swagger, '/users/{user-id}/relationship', 'get', targets)
} catch (err) {
  // do something with potential errors...
}

Within the browser

Include the swaggersnippet.min.js file created after building the the library (see above) in your HTML page:

<script type="text/javascript" src="path/to/swaggersnippet.min.js"></script>

Use Swagger Snippet, which now defines the global variable SwaggerSnippet.

Output

The output for every endpoint is an object, containing the method, url, a human-readable description, and the corresponding resource - all of these values stem from the specification. In addition, within the snippets list, an object containing a code snippet for every chosen target is provided. As of version 0.4.0, the snippets include examplary payload data.

If getSwaggerSnippets is used, an array of the above described objects is returned.

For example:

[
  ...
  {
    "method": "GET",
    "url": "https://api.instagram.com/v1/users/{user-id}/relationship",
    "description": "Get information about a relationship to another user.",
    "resource": "relationship",
    "snippets": [
      {
        "id": "node",
        "title": "Node + Native",
        "content": "var http = require(\"https\");\n\nvar options = {..."
      }
    ]
  }
  ...
]
