Doesn't work with ESM

[machineghost]

I tried to use this library, but apparently, it can't handle ES Modules (ie. "type": "module" in package.json),.

When I tried to run it, it immediately failed after trying to require one of my (ESM) API endpoints (feedback.js).

Error [ERR_REQUIRE_ESM]: require() of ES Module /home/me/project/next/pages/api/feedback.js from /home/me/project/next/node_modules/nextjs-http-supertest/index.js not supported.
Instead change the require of feedback.js in /home/me/project/next/node_modules/nextjs-http-supertest/index.js to a dynamic import() which is available in all CommonJS modules.

When I read the error, the problem is that you are using const package = require('package') instead of import package from 'package' doesn't it ?

Sorry, I should have included the stack trace to make things clearer ... and now I've stopped using Supertest and can't easily repro the error.

However, the core problem was that:

 const package = require('package')

wasn't coming from my code ... it was coming from Supertest code. My code is using ESM, and only has imports.

if your problem comes from using ESM in CJS project like error message suggests, try dynamic imports like below.

async function _load() {
  const server = await import('nextjs-http-supertest')

  // your codes
}
