Elite Pro Hacks For Vite Intermediate

Advanced performance tips and optimizations for Vite Intermediate

Dynamic chunk naming strategy

Code

chunkFileNames: (chunkInfo) => { const facadeModuleId = chunkInfo.facadeModuleId ? chunkInfo.facadeModuleId.split('/').slice(-1).replace(/\.[^.]*$/, '') : 'chunk'; return `chunks/[name]-[hash].js`; }

ImprovementPredictable chunks

Caveat

⚠️ Complex naming logic

Detect circular dependencies

Code

export default function circularPlugin() { return { name: 'circular', writeBundle() { analyzeDependencies(); } }; }

ImprovementPrevent infinite loops

Caveat

⚠️ Build-time analysis only

Inject metrics into bundle

Code

transformIndexHtml: (html) => html.replace('</body>', `<script>window.__BUILD_TIME__='${new Date().toISOString()}'</script></body>`)

ImprovementBuild metadata

Caveat

⚠️ Dev-time only

Multi-entry monorepo builds

Code

input: { app1: './apps/app1/index.html', app2: './apps/app2/index.html' }, output: { dir: 'dist', entryFileNames: '[name]/[name]-[hash].js' }

ImprovementIndependent builds

Caveat

⚠️ Requires careful config

Content hash for long-term caching

Code

entryFileNames: '[name]-[hash].js', chunkFileNames: '[name]-[hash].js, assetFileNames: '[name]-[hash][extname]'

ImprovementImmutable caching

Caveat

⚠️ Hash stability dependent
