[botoxparty]

When running a production build I get:

Uncaught TypeError: Super expression must either be null or a function, not undefined

I think this is similar to this: https://github.com/front/gutenberg-js/issues/14

[botoxparty]

Indeed it is, wouldn't really want to turn off optimisation though.

How would I go about debugging this?

[botoxparty]

Running npm build for the @front/g-editor also produces the same result.

https://www.npmjs.com/package/@frontkom/g-editor

[arnvanhoutte]

Have you find a way to fix this?

[botoxparty]

No, I would need sourcemaps for gutenberg-js.js

[arnvanhoutte]

@SofiaSousa Will this be looked at? Or is this a Wordpress issue?

[botoxparty]

I would be happy to work on the development of this to get it production ready @SofiaSousa if you could point me in the direction of source maps for gutenberg-js.js

Also I feel like this particular error could have something to do with it not registering that React is loaded?

@botoxparty that's would be great!, I hope you get help.

[SofiaSousa]

@botoxparty I'm not sure about what you are asking but you can check the source maps here https://unpkg.com/@frontkom/gutenberg-js@3.0.1/build/js/gutenberg-js.js.map or in gutenberg-js build folder after running npm run build.

@SofiaSousa can you please fix the production error: Uncaught TypeError: Super expression must either be null or a function, not undefined.

we will be very thankful

[SofiaSousa]

It's probably related with circular dependencies of the @wordpress/gutenberg packages and we probably can't do anything about that in gutenberg-js.

[botoxparty]

@SofiaSousa so do you get this same error? Are the current contributors going to continue working on this project or has it been abandoned?

[Qoraiche]

@SofiaSousa so there is no way to build? development server works fine for the g-editor but the build doesn't. any trick?

thanks again for your help

[SofiaSousa]

As @arnvanhoutte suggested at g-editor/issues/4:

At the moment: turning optimizations off.

Project is not abandoned, but solving this is not a priority. If you want to suggest a solution please create a pull request.

[Qoraiche]

@SofiaSousa i think it's Impossible/Difficult to use gutenberg-js in a production environment since the production build produces an unsolvable error! what is your solution? Thanks again

[Qoraiche]

This error has been fixed in the new update of g-editor.

[arnvanhoutte]

Excuse me if I have been getting this wrong, but the fix there seems to be to turn compression off: https://github.com/front/g-editor/commit/7e742d1e4bd91342d3ac6755a4aa00dae166b3be

I don't really see that as a fix, but more like a temporary workaround

[Qoraiche]

@arnvanhoutte , I think they can not fix this issue directly because it's caused circular dependencies inside Gutenberg itself. the only solution is to disable compression on the TerserPlugin front/g-editor@7e742d1.
