Elite Pro Hacks For Vite Advanced

Advanced performance tips and optimizations for Vite Advanced

Plugin memoization for expensive transforms

Code

const cache = new Map(); export default function memoPlugin() { return { name: 'memo', transform(code, id) { const key = `${id}:${code.length}`; if (cache.has(key)) return cache.get(key); const result = expensiveTransform(code); cache.set(key, result); return result; } }; }

Improvement+400% transform speed

Caveat

⚠️ Memory overhead

Conditional plugin loading per environment

Code

const plugins = process.env.VITE_ENV === 'test' ? [testPlugin()] : process.env.VITE_ENV === 'staging' ? [stagingPlugin()] : [productionPlugin()]

ImprovementEnvironment-specific optimization

Caveat

⚠️ Complex config logic

Automatic dependency analyzer

Code

export default function depAnalyzer() { const deps = {}; return { name: 'dep-analyzer', resolveId(id) { if (!id.startsWith('node:')) deps[id] = true; return null; }, buildEnd() { console.log('Dependencies:', Object.keys(deps)); } }; }

ImprovementBuild visibility

Caveat

⚠️ Post-build only

Smart chunk naming by frequency

Code

const frequency = {}; export default { chunkFileNames: (chunk) => { frequency[chunk.name] = (frequency[chunk.name] || 0) + 1; return frequency[chunk.name] > 5 ? 'hot/[name].js' : 'chunks/[name].js'; } }

ImprovementCaching optimization

Caveat

⚠️ Build-time statistics

Framework bridge plugin for multi-framework apps

Code

export default function bridgePlugin(frameworks) { return { name: 'bridge', resolveId(id) { for (const fw of frameworks) if (id.startsWith(`@${fw}/`)) return `\0${id}`; }, load(id) { for (const fw of frameworks) if (id.startsWith(`\0@${fw}/`)) return loadFromFramework(fw, id); } }; }
