# Example app with [babel-macros](https://github.com/kentcdodds/babel-macros)
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-babel-macros with-babel-macros-app
|
|
# or
|
|
yarn create next-app --example with-babel-macros with-babel-macros-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example:
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-babel-macros
|
|
cd with-babel-macros
|
|
```
|
|
|
|
Install it and run:
|
|
|
|
```bash
|

## The idea behind the example
|
|
|
|
This example features how to configure and use [`babel-macros`](https://github.com/kentcdodds/babel-macros) which allows you
|
|
to easily add babel plugins which export themselves as a macro without needing
|
|
to configure them.
|
|
|
|
You'll notice the configuration in `.babelrc` includes the `babel-macros`
|
|
plugin, then we can use the `preval.macro` in `pages/index.js` to pre-evaluate
|
|
code at build-time. `preval.macro` is effectively transforming our code, but
|
|
we didn't have to configure it to make that happen!
|
|
|
|
Specifically what we're doing is we're prevaling the username of the user who
|
|
ran the build.
