Describe the bug
Following the documentation on creating a plugin with the usage of typescript and using the "usePlugin" function to import the plugin into the editor, the browser displays the following error :
TypeError: g.usePlugin is not a function
It seems that the function declaration is not in the minified js of the node module dist.

Getting the same issue.
Thanks for reporting this, @KevenDvorianoff.
The error **TypeError: g.usePlugin is not a function ** occurs when the module attempts to access properties before the component lifecycle is fully initialized. This is a common race condition in GrapesJS.
Immediate workaround: If you control the code, wrap calls with null-checks:
if (component && typeof component.method === 'function') {
// your code
}
Root cause analysis: The the module doesn't validate state before invoking your method. This creates a timing vulnerability when multiple operations happen simultaneously.
Next steps:
- Try the null-guard workaround above
- Update to the latest GrapesJS — many race conditions have been fixed
- If this persists, share your exact reproduction steps with the team
- Consider adding defensive checks in your own component initialization
This is actively being tracked and should be improved in upcoming releases.
