js-library-distribution

To prevent global pollution when developing a JavaScript library, you must avoid modifying native prototypes or global objects. This practice ensures your library integrates safely into diverse customer environments without causing conflicts with existing scripts.

The best way to support tree-shaking in an npm package is to manage import side effects so code only executes upon explicit initialization. You should also provide dual ESM/CJS package formats to optimize bundling for your consumers.

To manage peer dependencies for an SDK and avoid version conflicts, utilize peer dependencies for safe integration into customer environments. This prevents your library from bundling duplicate versions of shared frameworks.

Yes, you can use dual ESM and CJS formats for TypeScript library distribution. Supporting dual package formats ensures broad compatibility across different module resolution strategies while maintaining tree-shaking optimization.

Your JavaScript SDK breaks existing functionality on a SaaS platform likely because it modifies native prototypes or introduces import side effects. Adhering to strict isolation patterns prevents global pollution and ensures safe integration.
