Swagger UI Restify ESM

Adds middleware to your restify app to serve the Swagger UI bound to your Swagger document. This acts as living documentation for your API hosted from within your app.

Swagger version is pulled from npm module swagger-ui-dist. Please use a lock file or specify the version of swagger-ui-dist you want to ensure it is consistent across environments.

This version of Swagger UI for Restify is compatible with ECMASCRIPT Modules.

Usage

Install using npm:

$ npm install --save swagger-ui-restify-esm

Restify setup app.mjs

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';
import swaggerSpec from './swagger.json' assert { type: "json" };

const server = restify.createServer();

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerSpec, { baseURL: "/docs/" }))

Open http://<app_host>:<app_port>/docs/ in your browser to view the documentation.

swagger-jsdoc

If you are using swagger-jsdoc simply pass the swaggerSpec into the setup function:

// Initialize swagger-jsdoc -> returns validated swagger spec in json format
const swaggerSpec = swaggerJSDoc(options);

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerSpec, { baseURL: "/docs/" }))

Swagger Explorer

By default the Swagger Explorer bar is hidden, to display it pass true as the 'explorer' property of the options to the setup function:

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';
import swaggerSpec from './swagger.json' assert { type: "json" };

const server = restify.createServer();

var options = {
  explorer: true,
  baseURL: 'docs/',
};

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerSpec, options))

Custom swagger options

To pass custom options e.g. validatorUrl, to the SwaggerUi client pass an object as the 'swaggerOptions' property of the options to the setup function:

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';
import swaggerSpec from './swagger.json' assert { type: "json" };

const server = restify.createServer();

var options = {
	swaggerOptions: {
    validatorUrl: null,
  },
  baseURL: 'docs/',
};

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerSpec, options))

Custom CSS styles

To customize the style of the swagger page, you can pass custom CSS as the 'customCss' property of the options to the setup function.

E.g. to hide the swagger header:

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';
import swaggerSpec from './swagger.json' assert { type: "json" };

const server = restify.createServer();

var options = {
  customCss: '.swagger-ui .topbar { display: none }',
  baseURL: 'docs/',
};

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerSpec, options))

Custom JS

If you would like to have full control over your HTML you can provide your own javascript file, value accepts absolute or relative path

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';
import swaggerSpec from './swagger.json' assert { type: "json" };

const server = restify.createServer();

var options = {
  customJs: '/custom.js',
  baseURL: 'api-docs',
};

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerSpec, options))

Load swagger from url

To load your swagger from a url instead of injecting the document, pass null as the first parameter, and pass the relative or absolute URL as the 'swaggerUrl' property of the options to the setup function.

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';

const server = restify.createServer();
var options = {
  swaggerUrl: 'http://petstore.swagger.io/v2/swagger.json',
  baseURL: 'docs/',
}

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(null, options))

Load swagger from yaml file

To load your swagger specification yaml file you need to use a module able to convert yaml to json; for instance yamljs.

npm install --save yamljs

import restify from 'restify';
import swaggerUi from 'swagger-ui-restify-esm';
import YAML from 'yamljs';

const server = restify.createServer();

const swaggerDocument = YAML.load('./swagger.yaml');

server.get("/docs/*", ...swaggerUi.serve)
server.get("/docs/", swaggerUi.setup(swaggerDocument, { baseURL: 'docs/' }))
