Ability to extract strings from intl-messageformat strings

[swac]

Which package?

intl-messageformat

Is your feature request related to a problem? Please describe.

I'd like to use intl-messageformat for a Node.js project. I've seen that there is a CLI for extracting strings from code into JSON files.

From the docs, I don't see an obvious way to achieve this. I have a string like this in my code:

const msg = new IntlMessageFormat('This is my string.', 'en-US').format();

I'd like to run the CLI to extract this into JSON in some way. I assume I would need to be able to specify an id and description for the string, but I'm not seeing where those would be specified.

Describe the solution you'd like

Something similar to react-intl's formatMessage or defineMessage functions would be great. If I could initialize a formatter with a locale, the way react-intl has IntlProvider, and then call formatMessage with an id, description, and defaultValue, that could work.

Describe alternatives you've considered

I'm new to this library and i18n in general, so I'm not sure what the alternatives would be.

@swac react-intl does support non-React env so maybe you can use that: https://github.com/formatjs/react-intl/blob/master/docs/API.md#createintl

Thanks @longlho! That approach seems to work great.
