VITE0007Remove unused Vite define constants
Flags unused define in Vite define code before it leaks into runtime behavior.
vite-doctor/viteconfigurationinfoNo fix
Why it happens
Vite configuration runs in both dev and build pipelines. Narrow, explicit settings reduce surprises across SSR, workers, and local file access.
Fix
Remove unused define, or move it to the Vite runtime/API that owns that behavior.
Example
Remove unused define constants
Before
export default defineConfig({
define: {
__UNUSED_FLAG__: JSON.stringify(true),
},
})
After
export default defineConfig({
define: {},
})
