`this.getModuleInfo().code` support in dev

[vladmiller]

Describe the bug

I am building a plugin that prerenders static pages from markdown/react components.

I am programmatically setting the entrypoints, provide the resolveId and load hooks to load the content.

In the reproduction code you will see that I first load load.html file and then, when I load the load.html I am also trying to load some-code?proxy module and get it's code.

In the build mode it works fine. With the dev mode, the load for proxy does not return code.

While debugging, I have noticed that build mode goes directly to rollup, however, in dev mode there is a PluginContext instead.

I have pinpointed the execution to the load method inside of PluginContext. It loads the source-code, however, the last call to this.getModuleInfo does not return the code. And the resulting ModueInfo does not contain anything except id and empty meta.

Reproduction

Steps to reproduce

pnpm install

# Build works fine
pnpm vite build

# Dev
pnpm vite

# Navigate to http://localhost:5173/home

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.
