SwaggerClient and data:url's

[poluyanov]

Hi folks!

I tried to handle data:url for spec instead and faced an exception.

The documentation said

var specUrl = 'http://petstore.swagger.io/v2/swagger.json'; // data urls are OK too 'data:application/json;base64,abc...'

but it does not work.

Example

  const swaggerSpecBase64 = fs.readFileSync(__dirname + '/../swagger.yml').toString('base64');
  client = await SwaggerClient(`data:text/yaml;base64,${swaggerSpecBase64}`);

throws

 /source/node_modules/node-fetch/lib/index.js:1309
	throw new TypeError('Only HTTP(S) protocols are supported');
		      ^
  TypeError: Only HTTP(S) protocols are supported

What is wrong here?

i guess a update to node-fetch@3 would add support for dataurls

Yes @jimmywarting is absolutely right. We need node-fetch@3.x to be able to add support for data URLs. Here is a POC:

import fs from 'node:fs';
import util from 'node:util';
import fetch from 'node-fetch';

const data = fs.readFileSync('./petstore.json').toString('base64');
const dataURL = `data:application/json;base64,${data}`;

const response = await fetch(dataURL);
const jsonBody = await response.json();

console.dir(jsonBody);

When #2414 and #2415 are processed this issue will autoresolve.

+1 This would be a great add to allow a local load of a swagger file vs relying on a hosted version. Looking to use this solution where adding an extra HTTP fetch is not ideal.
