How to skip SSL certificate checking?

[grzegorzblaszczyk]

When I do this:

import ky from 'https://unpkg.com/[email protected]/index.js';

(async () => {
  class HTTPError extends Error {}
  const response = await ky('https://some-url-with-invalid-ssl-cert.com/file.txt', {
    method: 'GET'
  });

  if (!response.ok) {
    console.log (`Response: ${response}`)
  }

})();

I get:

WARN RS - rustls::session:718 - Sending fatal alert BadCertificate

How to skip SSL certificate checking in ky?

ky is using the browser Fetch API underneath. I don't think this is possible.

In browsers it's not possible. However, if using it in node (for instance, in automated tests using avajs) it can be done like this:

(package.json)
  "ava": {
    "environmentVariables": {
      "NODE_TLS_REJECT_UNAUTHORIZED": "0"
    }
  }

Use only in development mode, like in tests.
