## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Download [`create-next-app`](https://github.com/segmentio/create-next-app) to bootstrap the example:
|
|
|
|
```
|
|
npm i -g create-next-app
|
|
create-next-app --example with-dotenv with-dotenv-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-dotenv
|
|
cd with-dotenv
|
|
```
|
|
|
|

|
## 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
|
|
```
