Readme
This is the Wordnik Swagger code for the restify framework. It's a fork of https://github.com/wordnik/swagger-node-express.git with some fixes to work with Restify.

READ MORE about swagger!
See the swagger website or the swagger-core wiki, which contains information about the swagger json spec.
Try a sample! The source for a functional sample is available on github:
Adding swagger to your restify-based API
Include swagger.js in your app and add restify as the app handler:
var restify = require("restify")
, url = require("url")
, swagger = require("swagger-node-restify");
var server = restify.createServer();
server.use(restify.bodyParser());
restify.defaultResponseHeaders = function(data) {
this.header('Access-Control-Allow-Origin', '*');
};
swagger.setAppHandler(server);
You can optionally add a validator function, which is used to filter the swagger json and request operations:
// This is a sample validator. It simply says that for _all_ POST, DELETE, PUT methods,
// the header api_key OR query param api_key must be equal to the string literal
// special-key. All other HTTP ops are A-OK */
swagger.addValidator(
function validate(req, path, httpMethod) {
// example, only allow POST for api_key="special-key"
if ("POST" == httpMethod || "DELETE" == httpMethod || "PUT" == httpMethod) {
var apiKey = req.headers["api_key"];
if (!apiKey) {
apiKey = url.parse(req.url,true).query["api_key"]; }
if ("special-key" == apiKey) {
return true;
}
return false;
}
return true;
}
);
You now add models to the swagger context. Models are described in a JSON format, per the swagger model specification. Most folks keep them in a separate file (see here for an example), or you can add them as such:
swagger.addModels(models);
Next, add some resources. Each resource contains a swagger spec as well as the action to execute when called. The spec contains enough to describe the method, and adding the resource will do the rest. For example:
var findById = {
'spec': {
"description" : "Operations about pets",
"path" : "/pet.{format}/{petId}",
"notes" : "Returns a pet based on ID",
"summary" : "Find pet by ID",
"method": "GET",
"params" : [swagger.pathParam("petId", "ID of pet that needs to be fetched", "string")],
"responseClass" : "Pet",
"errorResponses" : [swagger.errors.invalid('id'), swagger.errors.notFound('pet')],
"nickname" : "getPetById"
},
'action': function (req,res) {
if (!req.params.petId) {
throw swagger.errors.invalid('id'); }
var id = parseInt(req.params.petId);
var pet = petData.getPetById(id);
if(pet) res.send(JSON.stringify(pet));
else throw swagger.errors.notFound('pet');
}
};
swagger.addGet(findById);
Adds an API route to restify and provides all the necessary information to swagger.
Finally, configure swagger with a public
URL and version:
swagger.configure("http://petstore.swagger.wordnik.com", "0.1");
and the server can be started:
app.listen(8002);
Now you can open up a swagger-ui and browse your API, generate a client with swagger-codegen, and be happy.
Other Configurations
.{format} suffix removal
If you don't like the .{format} or .json suffix, you can override this before configuring swagger:
swagger.configureSwaggerPaths("", "/api-docs", "");
That will put the resource listing under /api-docs
, and ditch the .{format}
on each of the apis you're adding to. Make sure to set the paths correctly in your spec configuration though, like such:
// note the .{format} is removed from the path!
var findById = {
'spec': {
"description" : "Operations about pets",
"path" : "/pet/{petId}",
"notes" : "Returns a pet based on ID",
...
