+# @geprog/vite-plugin-env-config
+
+Vite plugin for providing configurations from environment variables at runtime.
+
+## Usage
+
+Add `envConfig` plugin to `vite.config.js / vite.config.ts`:
+
+```js
+// vite.config.js / vite.config.ts
+import { envConfig } from '@geprog/vite-plugin-env-config';
+
+export default {
+  plugins: [envConfig()],
+};
+```
+
+Add a template file to your project at `./src/assets/env-config.template.js`:
+
+```js
+// ./src/assets/env-config.template.js
+(function (window) {
+  window.env = window.env || {};
+
+  // add a line for each environment variable
+  window['env']['BACKEND_URL'] = '${BACKEND_URL}';
+})(this);
+```
+
+Include `/assets/env-config.js` in your `index.html`:
+
+```html
+<!-- index.html -->
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <script src="/assets/env-config.js"></script>
+  </head>
+</html>
+```
+
+To access the environment variables use the built-in getter:
+
+```ts
+import { getEnvConfig } from '@geprog/vite-plugin-env-config';
+
+const backendURL = getEnvConfig('BACKEND_URL');
+```
+
+For production use `envsubst` as outlined in the [next section](#motivation).
+
+## Motivation
+
+To adhere to the principles of the [twelve-factor app](https://12factor.net/config)
+you might need to access environment variables that are set when your frontend server starts.
+Instead of building your frontend on startup,
+you can use a config template like the one above and populate it using `envsubst`:
+
+```Dockerfile
+CMD ["/bin/sh", "-c", "envsubst < ./src/assets/env-config.template.js > ./dist/assets/env-config.js && exec nginx -g 'daemon off;'"]
+```
+
+`@geprog/vite-plugin-env-config` provides the same functionality for your development environment.
