What are the common pitfalls of tree shaking in JavaScript?
Some common pitfalls include not using ES6 modules, relying on dynamic imports, and not configuring your bundler correctly.
Why is using ES6 modules important for tree shaking?
ES6 modules allow static analysis, which helps bundlers identify unused code more effectively.
Can you give an example of a dynamic import issue?
Sure! If you use dynamic imports, the bundler may not be able to determine which parts of the code are unused, leading to larger bundle sizes.
How can I configure my bundler for better tree shaking?
Make sure to set the 'sideEffects' property in your package.json and use tools like Webpack or Rollup with proper settings.
Are there any tools to help analyze tree shaking effectiveness?
Yes, tools like Webpack Bundle Analyzer and Source Map Explorer can help you visualize and analyze your bundle.
