@arbocollab/arbo-ckeditor-custom-build

Custom CKEditor 5 build with:

• ESM entry (tree‑shakable) -> dist/esm/main.js
• IIFE (CDN/global) -> dist/umd/ckeditor.js (global: window.ArboCKEditor)
• Duplicate‑load protection (prevents two distinct CKEditor 5 engine graphs on the same page)

NOTE: A CommonJS build is NOT currently emitted. Existing package.json fields that point at dist/cjs/* will need adjusting if you truly need CJS; otherwise consumers should use ESM or the IIFE. See "Package JSON alignment" below.

Install (ESM / bundlers)

npm install @arbocollab/arbo-ckeditor-custom-build

Use (ESM)

import { ClassicEditor } from '@arbocollab/arbo-ckeditor-custom-build';
ClassicEditor.create(document.querySelector('#editor')!);

CDN (Global IIFE)

<script src="https://cdn.jsdelivr.net/npm/@arbocollab/[email protected]/dist/umd/ckeditor.js"></script>
<script>
  ArboCKEditor.ClassicEditor.create(document.getElementById('editor'));
  // ArboCKEditor exports: ClassicEditor, BalloonEditor, createClassicEditor, createBalloonEditor
}</script>

CDN (ESM import)

<script type="module">
  import { ClassicEditor } from 'https://cdn.jsdelivr.net/npm/@arbocollab/[email protected]/dist/esm/main.js';
  ClassicEditor.create(document.querySelector('#editor'));
</script>

Avoid double loading

Do NOT both import the ESM bundle and include the IIFE script; the guard in index.ts will abort the second copy to prevent ckeditor-duplicated-modules errors.

Duplicate build protection

If a second distinct CKEditor 5 engine instance is detected, this build logs an error and throws early to keep the page stable.

Package JSON alignment

Current repo build emits:

dist/
  esm/main.js
  umd/ckeditor.js

If you do not produce dist/cjs/*, remove or update the main / exports.require fields before publishing to avoid broken "require()" consumers. Simplest minimal export map (ESM + CDN) could be:

{
  "main": "dist/umd/ckeditor.js", // optional legacy entry
  "module": "dist/esm/main.js",
  "exports": { ".": { "import": "./dist/esm/main.js", "default": "./dist/esm/main.js" } },
  "unpkg": "dist/umd/ckeditor.js",
  "jsdelivr": "dist/umd/ckeditor.js"
}

Only add CJS paths back if you reinstate the commented CJS build in rollup.config.mjs.

Publishing (summary)

npm version patch -w @arbocollab/arbo-ckeditor-custom-build
TARGET=ckeditor npx rollup -c      # or your build script
npm publish -w @arbocollab/arbo-ckeditor-custom-build --access public

Troubleshooting

| Issue | Fix | |-------|-----| | 404 / ENEEDAUTH | Re-login: npm whoami; ensure npmjs registry for this scope | | Duplicate build error | Remove extra CKEditor bundle / script tag | | Missing CJS file | Adjust package.json (see above) or enable CJS build |
