Postman to swagger

We like to use postman, but often we get asked for swagger docs. There doesn't seem to be any open source postman v2.0.0 => swagger/openApi tools. Maybe a commercial reason, here is one for you.

Usage

import postmanToSwagger from 'postman-to-swagger';

const convertAndSave = postmanJson => {
  // This returns the actual swagger v2.0 spec as a json
  const swaggerJson = postmanToSwagger(postmanJson);

  // Example if you want to save it somewhere
  fs.writeFile(
    '../_docs/swagger.json',
    JSON.stringify(swaggerJson, null, 2),
    'utf8'
  );
};

With swagger-ui-express

import postmanToSwagger from 'postman-to-swagger';
import swaggerUi from 'swagger-ui-express';
import mockCollection from './mockCollection.json';

swagger.get('/swagger', swaggerUi.setup(postmanToSwagger(mockCollection)));
// Static stuff
swagger.use('/', swaggerUi.serve, (req, res) => res.status(404).end());

What it converts

• name, description, version
• routes, folders
• examples, status codes

Demo

# Build this lib
npm run build
# Go into demo folder and install
npm install
# Then run the demo
npm run watch

Future improvement

• Apimatic has this models thing that is kind of useful, maybe we can also do that.
• Use lodash/fp, lodash/fp/flow to slim down module size

Repos to watch

• api-flow - broken, but maybe inspiring.
• postman2swagger2 - Doesn't support postman v2
