Línea de trabajo

Reproduce the issue by running the Rolldown panel's “Run build” or VITE_DEVTOOLS_ROLLDOWN=true vite build with devtools.apply set to serve. Start by tracing the build integration from that entry point to node_modules/.rolldown/; done means a new sid_* session is written and appears in the panel without leaving the build hanging.

Descripción

bug
Describe the bug

In practice, no config gives you a "Run build" that both records a session and exits cleanly.

Versions

  • vite 8.3.2
  • @vitejs/devtools 0.7.6
  • @vitejs/devtools-rolldown 0.7.6

Config

export default defineConfig({
  devtools: { apply: "serve" },
})

apply: "serve" is needed because with the default (devtools: true / apply: "all"), vite build starts a standalone DevTools server after the build and never exits. That hangs CI.

I was a able to hack it using the config below.

Workaround

build: {
  rolldownOptions: {
    ...(process.env["VITE_DEVTOOLS_ROLLDOWN"] === "true" && { devtools: {} }),
  },
},
devtools: { apply: "serve" },

Love the tool btw! Exactly what I needed and a considerable upgrade from the old plugin approach that created simple static files.

Reproduction

Steps to reproduce

  1. Run vite (dev server).
  2. Open the Rolldown panel in the DevTools dock.
  3. Click "Run build".

Expected:

A new session is written to node_modules/.rolldown/ and shows up in the panel.

Actual:

The build finishes successfully, but no session is written and the panel has nothing new to show. Running the same command by hand gives the same result:

VITE_DEVTOOLS_ROLLDOWN=true vite build   # no new node_modules/.rolldown/sid_* directory
