Parse styles to a Css string

快速解答by artf

Well, you should be able to take the CSS from any GrapesJS instance with editorInstance.getCss(). Which basically generates the CSS from the styles JSON

Question

Hi @artf !

  "editor": {
    "css": "* { box-sizing: border-box; } #wrapper{font-family:Helvetica,Arial Black, sans-serif;color:#9500b3;}",
    "html": "<div id=\"iecr\">Insert your text here</div>",
    "assets": "[]",
    "styles": "[{\"selectors\":[\"#wrapper\"],\"style\":{\"font-family\":\"Helvetica,Arial Black, sans-serif\",\"color\":\"#9500b3\"}},]",
    "components": "[]"
  }
}

Is there any way to parse the styles into a CSS string? This would be helpful in a scenario where you have multiple GrapesJs instances stored and you want to update the CSS on all of them. You can manipulate the styles because that is an array and it's reliable. Currently, on the CSS I am using regex to locate and update. Would prefer to parse the editor.styles and override the editor.css.

Thanks for reporting this, @lacieri.

Great question about [QUESTION]: Parse styles to a Css string. The recommended approach with StyleManager is to use the event-driven API.

Start here:

  1. Check the GrapesJS documentation for your specific module
  2. Look for the on() event listener method
  3. Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));

  • Share a minimal CodeSandbox reproduction
  • Include what you've already tried
  • Mention your GrapesJS version
