[Suggestion] Consider using `esbuild` for 100x speedup

[andreialecu]

Do you want to request a feature or report a bug?

https://github.com/evanw/esbuild is a new bundler that is 100x more performant than current JS based bundlers. Large code-bases can be bundled and minified in under a second.

One issue with full migration to esbuild is that babel plugins would not be supported. However, for users who do not use babel plugins, or who can work around it, there could be an option to switch metro from using babel to esbuild.

Alternatively, just the minifier from esbuild could be used, as an extra option to terser or uglify.

Another option is swc https://swc.rs

Any updates on this? We're trying to bundle a complex react-native monorepo which currently takes about 15 min to build js on a i7 macbook pro.
