We want to change the defaults for `revealOrder` and `tail` on SuspenseList. This is an intermediate step to allow experimental users to upgrade. To explicitly specify these options I added `revealOrder="independent"` and `tail="visible"`. I then added warnings if `undefined` or `null` is passed. You must now always explicitly specify them. However, semantics are still preserved for now until the next step. We also want to change the rendering order of the `children` prop for `revealOrder="backwards"`. As an intermediate step I first added `revealOrder="unstable_legacy-backwards"` option. This will only be temporary until all users can switch to the new `"backwards"` semantics once we flip it in the next step. I also clarified the types that the directional props requires iterable children but not iterable inside of those. Rows with multiple items can be modeled as explicit fragments.
SSR Fixtures
A set of test cases for quickly identifying issues with server-side rendering.
Setup
To reference a local build of React, first run npm run build at the root
of the React project. Then:
cd fixtures/ssr
yarn
yarn start
The start command runs a webpack dev server and a server-side rendering server in development mode with hot reloading.
Note: whenever you make changes to React and rebuild it, you need to re-run yarn in this folder:
yarn
If you want to try the production mode instead run:
yarn start:prod
This will pre-build all static resources and then start a server-side rendering HTTP server that hosts the React app and service the static resources (without hot reloading).
