A step‑by‑step guide to configuring Rollup for reliable tree‑shaking and custom chunk splitting, including sideEffects declaration, manualChunks strategy, and verification with rollup-plugin-visualizer.
Stop managing fragmented build pipelines. Learn how Bun's integrated bundler replaces separate compilers and minifiers with a single, high-performance command.
Bun's integrated bundler handles TypeScript, JSX, and npm resolution in one command. Here is when it fits and when it does not.
Import only the Array.flat polyfill from core-js to support IE11 and Safari 10 without bloating your JavaScript bundle.
When ES2021 array methods like flat() fail silently across runtimes, core-js provides the polyfill—but integration requires deliberate tree-shaking, version selection, and early injection to avoid bundle bloat and global pollution.
Bun's built-in bundler can replace a sprawling webpack config with a single Bun.build() call. Here's a worked migration, how to verify the output, and where webpack still wins.
Learn how Rollup analyzes ES module graphs to drop unused exports, see a minimal configuration example, and understand the limits and common pitfalls that affect tree-shaking effectiveness.
Learn how Bun’s esbuild‑based bundler gives you instant builds for small JavaScript projects, with a concrete example, trade‑offs and next steps.
Bun’s single‑pass bundler slashes build times by up to 80% in large monorepos. A hands‑on example shows how to bundle TypeScript, JSX, and CSS with one command, compare timing to esbuild, and discuss trade‑offs like dynamic imports and code splitting.
