Uses export conditions to return environment information in a way that works with major bundlers and runtimes.
npm install esm-envUses export conditions to return environment information in a way that works with major bundlers and runtimes.
Install with npm install esm-env, then import as needed:
``js`
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.
Thank you to dominikg for refining the approach used by this library to suggest a more scalable method for adding additional conditions.
