+# 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:
+
+```js
+import { BROWSER, DEV, NODE } from 'esm-env';
+```
+
+Specify `conditions` in your bundler or runtime. For example:
+- [Node.js](https://nodejs.org/api/cli.html#-c-condition---conditionscondition)
+- [Bun](https://bun.sh/docs/runtime/modules#custom-conditions)
+- [Vite/Vitest](https://vite.dev/config/shared-options#resolve-conditions)
+- [webpack](https://webpack.js.org/configuration/resolve/#resolveconditionnames)
+
+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](https://github.com/dominikg) for refining the approach used by this library to suggest a more scalable method for adding additional conditions.
