Uses flow-parser to scan the
potentially-flow-typed JavaScript AST file for import and require statements.
It rewrites modules according to the options passed in.
This behaves very similar to the
rewrite-module
in babel-preset-fbjs from the
fbjs package. The difference here is that
it isn't done through Babel, but through flow-parser, and therefore keeps flow types intact.
prefix: Module prefix to prepend to all rewritten modules. (defaults to './')
map: moduleMap to use for rewriting modules (empty by default)
flow: options to pass to flow-parser. See https://www.npmjs.com/package/flow-parser#options
