GrapesJS is a free and open-source Web Builder Framework designed to facilitate the creation of HTML templates, websites, newsletters, and mobile applications. It's primarily intended for integration into Content Management Systems (CMS) to provide a powerful visual editing experience. The current stable version is `0.22.15`, with the project demonstrating a positive and sustainable release cadence, frequently publishing patch releases. Key differentiators include its framework-centric approach, offering core UI components like a Block Manager, Style Manager, Layer Manager, Code Viewer, and Asset Manager. It focuses on generating clean, standards-based HTML and CSS output, unlike some other tools that might rely on specific frontend frameworks.
npm install grapesjsVerified import paths — ran on the pinned version, not inferred.
This quickstart initializes a GrapesJS editor in a designated DOM element, configures local storage for persistence, and adds a few basic draggable blocks (section, text, image). It also includes basic panel configurations and logs the generated HTML and CSS on content updates.
Update `require('grapesjs')` or global script references to use `grapesjs` (lowercase 'g'). For ESM, use `import grapesjs from 'grapesjs';`.Refactor custom component registrations from `model: defaultModel.extend({...})` to `model: { defaults: {...} }` as per the updated documentation.For npm installations, add `import 'grapesjs/dist/css/grapes.min.css';` to your entry file. For CDN usage, include `<link rel="stylesheet" href="//unpkg.com/grapesjs/dist/css/grapes.min.css">` before your script.
Avoid manipulating components with `replaceWith()` directly within complex lifecycle event handlers, especially when UndoManager is active. Consider deferring the operation or temporarily disabling UndoManager around such critical operations if absolutely necessary. Review GrapesJS issue tracker for specific workarounds or fixes related to your version.
Ensure `import grapesjs from 'grapesjs';` is at the top of your module, or for global scripts, that `<script src="path/to/grapes.min.js"></script>` is loaded before attempting to call `grapesjs.init()`.
Verify the CDN link or local script path for `grapes.min.js` is correct and accessible. Ensure the script tag is placed before any inline script that attempts to use `grapesjs`.
This is an active bug. Check the GrapesJS GitHub issues for potential fixes, workarounds, or official patch releases. Temporarily, you might need to try slightly older patch versions or implement custom logic to guard against `null` references where `hasFocus` is called.
