babel-plugin-transform-raw-jsx's Issues

Invalid reactive assignment in async functions

Consider the following code:

let text = 'hello world'
let foo = await bar()
let view

if (foo.baz > .5)
  view = (<i>{text}</i>)
else
  view = (<b>{text}</b>)

Currently, this will lead to a runtime error, because of a conflict with how Babel rewrites the async function, and how scopes are handled by the plugin.

As a fix, two things can be done:

  1. Force a scope to exist when the plugin runs.
// Note that we added the brackets
if (foo.baz > .5) {
  view = (<i>{text}</i>)
} else {
  view = (<b>{text}</b>)
}
  1. Force babel to use another scope for variable assignment.
// This is a single statement, so Babel won't bother creating a new scope
// and no conflict will result from this; yay!
view = foo.baz > .5 ? (<i>{text}</i>) : (<b>{text}</b>)
