Dynamically enable ssr during react-router build?

[andrioidApacta]

Hi everyone! I'm considering taking our SPA to SSR; but I still need to build both versions until we're ready.

The ssr: false option is set in the configuration file. Is there any way to override that during build; or build both?

I'd really like to avoid patching the configuration file to achieve this. Is there a CLI option I missed?

You can enabled SSR, and then in your code ensure you only do CSR using something like ClientOnly. This will still SSR a fallback UI when requesting a document but the actual UI will be CSR-ed.

Also note that SPA navigations style is still going to happen with SSR enabled, the only difference with SSR enabled is that now instead of a single static HTML file you will send a HTML generated at the moment which can have content or it can be a fallback UI.

Thanks for your reply. My problem is that I'm shipping a static client bundle to a CDN and I can't stop doing that until I'm confident in the SSR version is working as intended. So, I want to build both while I'm transitioning.

npx react-router build --ssr false to override the configuration would solve my issue
