Summary

This is a general refresh PR, which sets the project up for Node 20 support in a forthcoming BackstopJS release.

Details

• configure .eslintrc.js to use ecmaVersion: 2020
• general eslint formatting adjustments with the latest rules
  • adds eslint-disable where necessary
• updates addon-test-support/index.js export — this was not working with ember-cli@^5.4.0, or perhaps @ember-test-helpers@^3.2.0
• specify "type": "commonjs" in package.json
• update all the things

General Testing Performed

• ✓ ember install ember-backstop
• ✓ ember generate acceptance-test home-test
• File: tests/acceptance/home-test.js Line 3: import backstop from 'ember-backstop/test-support/backstop';
• File: tests/acceptance/home-test.js

  15:   test('it renders the thing', async function (assert) {
  16:     await visit('/');
  17:     await backstop(assert);
  18:     assert.dom('#ember-welcome-page-id-selector').exists();
  19:   });

@garris this PR sets dependencies.backstopjs to "^6.3.3 and bumps debug to "^4.3.4", but includes everything in #87 as well.

@garris would you need any help to merge and release it?

[garris]

@villander Actually yes. It took a while to get 6.3.x stable-- would be great to get this done now that we're stable on the backstop side!

If you could bump backstop to latest and get a clean test I would gladly pull it in.

Please let me know if you need anything else from me.

Cheers

@garris is there any CI in this repo? would be great to have the ember tests running here. I'll test this branch with my app and get back to you.

[garris]

Hi @villander -- unfortunately no CI tests yet -- would be great to set that up. That said, this project is in maintenance mode at this point -- not anticipating any major contributions. But if you add some CI tests I will add it to the GH actions section.
