  • A much smaller community, so unusual problems have fewer existing answers than React

Webpack

  • Build times slower than Go-based bundlers like esbuild, especially for large codebases
  • Configuration fragmentation across many plugins increases maintenance burden

Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Webpack: What can Webpack bundle?

Webpack can bundle JavaScript modules along with static assets including PNG, CSS, JPG, SASS, HBS files, and more, creating single or multiple chunks for browser usage.

Source
Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.

Webpack: Does Webpack require configuration?

Webpack supports both zero-config and custom configuration approaches. For simple projects, no configuration is needed, but complex builds benefit from webpack.config.js customization.

Source
Webpack: What is the 2026 roadmap for Webpack?

Webpack's 2026 roadmap includes native CSS module support, universal target compilation for multiple environments, lazy barrel optimization, and advancement toward version 6.

Source
Webpack: How does Webpack handle code splitting?

Webpack can create multiple chunks from a single entry point that are asynchronously loaded at runtime, reducing initial page load time by deferring non-critical code.
