optimizeDeps: circular chunk dependency causes TDZ error with molstar (regression in beta.13 / rolldown rc.3) #597
Description
Describe the bug
vite@8.0.0-beta.13 (rolldown 1.0.0-rc.3) introduced a regression where optimizeDeps produces chunks with circular imports that cause runtime errors. Works fine on 8.0.0-beta.11 (rolldown 1.0.0-rc.2).
Expected behavior
Chunks produced by optimizeDeps should not have circular imports that break top-level initialization, or the shared chunk should contain the entry chunk's code to avoid the cycle.
Browser console:
Uncaught TypeError: Cannot read properties of undefined (reading 'MappedStatic')
at getSecondaryStructureParams (molstar_lib_mol-model-props_computed_secondary-structure__js.js:10:33)
The optimized output has this circular structure:
zhang-skolnik-*.js (shared) ──imports──> secondary-structure.js (entry)
^ │
└──────────────imports─────────────────────┘
Workaround doesn't work, causes cascading CJS issues
optimizeDeps: {
exclude: ["molstar"],
