This disables symbol renaming in production builds. The original
variable and function names are preserved. All other forms of
compression applied by Closure (dead code elimination, inlining, etc)
are unchanged — the final program is identical to what we were producing
before, just in a more readable form.
The motivation is to make it easier to debug React issues that only
occur in production — the same reason we decided to start shipping
sourcemaps in #28827 and #28827.
However, because most apps run their own minification step on their npm
dependencies, it's not necessary for us to minify the symbols before
publishing — it'll be handled the app, if desired.
This is the same strategy Meta has used to ship React for years. The
React build itself has unminified symbols, but they get minified as part
of Meta's regular build pipeline.
Even if an app does not minify their npm dependencies, gzip covers most
of the cost of symbol renaming anyway.
This saves us from having to ship sourcemaps, which means even apps that
don't have sourcemaps configured will be able to debug the React build
as easily as they would any other npm dependency.
* Remove Blocks
* Remove Flight Server Runtime
There's no need for this now that the JSResource is part of the bundler
protocol. Might need something for Webpack plugin specifically later.
* Devtools
This is equivalent to the jsx-runtime in that this is what the compiled
output on the server is supposed to target.
It's really just the same code for all the different Flights, but they
have different types in their arguments so each one gets their own entry
point. We might use this to add runtime warnings per entry point.
Unlike the client-side React.block call this doesn't provide the factory
function that curries the load function. The compiler is expected to wrap
this call in the currying factory.
* Add Flight Build and Unify HostFormat Config between Flight and Fizz
* Add basic resolution of models
* Add basic Flight fixture
Demonstrates the streaming protocol.
* Rename to flight-server to distinguish from the client parts
* Add Flight Client package and entry point
* Fix fixture
