Output with TSX missing React import about intlc HOT 4 CLOSED

Going potentially further than this it's possible to use the aforementioned backend but still not require the imports, for example:

As a first version, perhaps it'll be fine to just find any possible nodes that have the tsx backend and import React regardless if we find one in the json. Even if we don't use any fragment or other react feature, I think the import won't have any impact on the runtime code. WDYT?

I'm suggesting this mainly because I have no idea what I'm doing with haskell so I'll need a simpler scope at first I think

This isn't worth extra effort to support right now, but long-term I can imagine someone wanting to use intlc with only the ts backend, not having React installed, and discovering an error due to an inapplicable import.

It'd be good to at least track support for that in another ticket. To my mind that should be solved before we potentially open source* this later in the year once the dust has settled on our web implementation.

* I think this is a good candidate for open sourcing with a blog post attached detailing how we solved internationalisation and why we opted to write our own tool.

I think import * as React from 'react'; would suffice.

For this case we could just include the import anyway and trust that tree shaking will remove it.

Note I think there are two reasons we need to import React:

• so we can reference the type React.ReactElement
• JSX compiles to React.createElement so React must be in scope

With the new JSX transform (PR), we no longer need to worry about importing React for JSX compilation. Once we've migrated to the new transform, the React import will still be necessary but only so we can reference the types.

That is the approach I took. Eager to get feedback on this PR, it's the first haskell real code I write ;)
