SSR Using `ModuleRunner` API

::: tip Feedback
Give us feedback at Environment API feedback discussion
:::
server.ssrLoadModule has been replaced by importing from a Module Runner.
Affected scope: 
Vite Plugin Authors
::: warning Future Deprecation
ModuleRunner was first introduced in 
v6.0. The deprecation of 
server.ssrLoadModule is planned for a future major. To identify your usage, set 
future.removeSsrLoadModule to 
"warn" in your vite config.
:::
Motivation
The 
server.ssrLoadModule(url) only allows importing modules in the 
ssr environment and can only execute the modules in the same process as the Vite dev server. For apps with custom environments, each is associated with a 
ModuleRunner that may be running in a separate thread or process. To import modules, we now have 
moduleRunner.import(url).
Migration Guide
Check out the Environment API for Frameworks Guide.
server.ssrFixStacktrace and 
server.ssrRewriteStacktrace do not have to be called when using the Module Runner APIs. The stack traces will be updated unless 
sourcemapInterceptor is set to 
false.
