esm-env v1.2.1

esm-env

Uses export conditions to return environment information in a way that works with major bundlers and runtimes.

Usage

Install with npm install esm-env, then import as needed:

import { BROWSER, DEV, NODE } from 'esm-env';

Specify conditions in your bundler or runtime. For example:

• Node.js
• Bun
• Vite/Vitest
• webpack

If esm-env is used in both bundled code and an externalized library, you will need to specify conditions both at build-time and run-time.

Acknowledgements

Thank you to dominikg for refining the approach used by this library to suggest a more scalable method for adding additional conditions.
