# With Dotenv example
## How to use
### Using `create-next-app`
Download [`create-next-app`](https://github.com/segmentio/create-next-app) to bootstrap the example:

create-next-app --example with-dotenv with-dotenv-app
```

## The idea behind the example
This example shows the most basic idea of babel replacement from multiple environment. We have 1 env variable: `TEST` which will be replaced in development env and in production env with different babel plugin. In local development, babel reads .env file and replace process.env.* in your nextjs files. In production env (such as heroku), babel reads the ENV and replace process.env.* in your nextjs files. Thus no more needed to commit your secrets anymore.
Of course, please put .env* in your .gitignore when using this example locally.
## Troubleshooting
### Environment variables not showing on the page
If for some reason the variable is not displayed on the page, try clearing the `babel-loader` cache:
```
rm -rf ./node_modules/.cache/babel-loader
```
