Wanted to share that I created a couple of packages to make working with fluent and react easier. Both packages are in https://github.com/udacity/fluent-react-utils and are currently at their very beginning stages.
This will parse your react source code and pull out l10n IDs and messages (and comments!) and compile everything it finds into an ftl file for you.
This one allows for custom Localized components to make reading and writing fluent-react source code more succinct. (It also pairs closely with fluent-react-extract)
I’d love to hear some feedback about these packages. As I said, they are still very much in their infancy, so anything that jumps out as a change we should consider, feel free to file an issue.
