Consume variables in your environment with the Preact CLI
npm install @marvman/preact-cli-plugin-env-varsConsume variables in your environment with the Preact CLI.
 
```
$ yarn add @marvman/preact-cli-plugin-env-vars
And include in your project by creating a preact.config.js:
`js
import envVars from "@marvman/preact-cli-plugin-env-vars";
export default function (config, env, helpers) {
envVars(config, env, helpers);
}
`
The plugin allows to use any environment variables prefixed with PREACT_APP_ to be used within your script:
`js`
console.log(process.env.PREACT_APP_SECRET_CODE);
The environment variables are embedded during the build time.
To define permanent environment variables, create a file called .env in the root of your project:
```
PREACT_APP_SECRET_CODE=abcdef
These variables will act as the defaults if the machine does not explicitly set them.
Please refer to the dotenv documentation for more details.
