Webpack to Vite: Improving Speed and Performance

Description and use

Migrating from Webpack to Vite reduced build times, improved performance, and simplified configuration.

Problem

The build process was slow and resource‑intensive, hindering development speed.

Outcome

The migration cut build times by a significant margin, improved developer experience, and simplified the build configuration.

Workflow

• 1. Identified build bottlenecks in Webpack.
• 2. Set up a Vite project with minimal configuration.
• 3. Migrated source files and updated import paths.
• 4. Replaced Webpack plugins with Vite equivalents or native features.
• 5. Tested development server and production builds.
• 6. Benchmarked performance before and after migration.
• 7. Adjusted configuration for edge cases and third‑party libraries.
• 8. Deployed the new build pipeline to production.

Evidence

We migrated from Webpack to Vite to improve build speed and performance.

Source

Vite’s dev server is built on native ES modules, which eliminates the need for bundling during development.
