AE Expressions in external JSX: how does it work currently?

[johnm029]

This is an edited version of my original post, which contained errors (I figured out my mistake).

But I would like to know if there is any reference available about how to format JSX/JSON files to use with the footage() method. I want to be able to build an external functions library. Thanks!

Hello. Here is a github repo with exactly what you want to do. You have an exmple of how the file can look like and how to use it. If you look at the user's repos, you will find some more similar.

Exactly what I needed, DoruCatana. Thank you!

We also have a jsx function library which might be quite similar to what you're looking to do.

Feel free to let me know if you have any questions about it.

Even more enlightening. Thank you, Tim!

I made this 1 minute tutorial which describes the process:

In a nutshell, your files must look like normal JSON files, but may also contain functions as values, which is not permitted in JSON. Therefore, you also have to name them jsx, since it is not proper JSON anymore.

Thanks, Mathias. Your video actually started me down this path!
