Expose node API for extracting message IDs out of a file #619

Closed hjylewis closed 4 years ago

hjylewis commented 4 years ago

Let me know if this functionality already exists. I haven't been able to find an easy way of doing it.

Which package? @formatjs/cli

Is your feature request related to a problem? Please describe. I'm developing a library to inject message translations on a per-file basis so that messages will be dynamically added to a bundle. Given a file, this library needs to be able to detect what IDs are used in that file.

Describe the solution you'd like I would like an API to extract the messages from a file programmatically without outputting them to a file. This would look like a function that given a filename, returns the array of messages. @formatjs/cli already does this internally, I am asking for that function to be exported for external use.

Without this, libraries will have to reproduce the logic in @formatjs/cli which is prone to breaking as the library updates. libraries like https://github.com/akameco/extract-react-intl-messages already do this.

Describe alternatives you've considered It might be possible to run the cli in a child process and read the standard output?

Have you tried babel-plugin-react-intl?

hjylewis commented 4 years ago

I'm aware of babel-plugin-react-intl. How would I use it in this context? I would have to run it using babel which would require the user's babel config which is what @formatjs/cli is already doing under the hood, right?

This should be in @formatjs/cli@1.4.1
