Generate Swagger JSON API from NextJS Api Routes

🏠 Homepage

✨ Demo

Prerequisites

  • nextjs >= 9

Motivation

This package reads your JSDoc-annotated source code on NextJS API route and generates an OpenAPI (Swagger) specification.

nextjs + swagger-jsdoc = next-swagger-doc

Install

yarn add next-swagger-doc

Usage #1: Create an single API document

yarn add next-swagger-doc swagger-ui-react
  • Create an live swagger page, e.g: pages/api-doc.tsx
import { GetStaticProps, InferGetStaticPropsType } from 'next';

import { createSwaggerSpec } from 'next-swagger-doc';
import SwaggerUI from 'swagger-ui-react';
import 'swagger-ui-react/swagger-ui.css';

const ApiDoc = ({ spec }: InferGetStaticPropsType<typeof getStaticProps>) => {
  return <SwaggerUI spec={spec} />;
};

export const getStaticProps: GetStaticProps = async ctx => {
  const spec: Record<string, any> = createSwaggerSpec({
    definition: {
      openapi: '3.0.0',
      info: {
        title: 'NextJS Swagger',
        version: '0.1.0',
      },
    },
  });
  return {
    props: {
      spec,
    },
  };
};

export default ApiDoc;

Usage #2: Use NextJS API route to create Swagger JSON spec

  • Step 1: Create an api route on nextjs, e.g: pages/api/doc.ts
import { withSwagger } from 'next-swagger-doc';

const swaggerHandler = withSwagger({
  definition: {
    openapi: '3.0.0',
    info: {
      title: 'NextJS Swagger',
      version: '0.1.0',
    },
  },
  apiFolder: 'pages/api',
});
export default swaggerHandler();
  • Step 2: Add JSdoc to any NextJS API routes, for example: pages/api/hello.ts
import { NextApiRequest, NextApiResponse } from 'next';

/**
 * @swagger
 * /api/hello:
 *   get:
 *     description: Returns the hello world
 *     responses:
 *       200:
 *         description: hello world
 */
const handler = (_req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json({
    result: 'hello world',
  });
};

export default handler;
  • Step 3: Access the Swagger API doc
