# A statically generated blog example using Next.js and Prepr
This example showcases Next.js's [Static Generation](https://nextjs.org/docs/basic-features/pages) feature using [Prepr](https://prepr.io/) as the data source.
Once you have access to [the environment variables you'll need](#step-3-set-up-environment-variables), deploy the example using [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example):

## How to use
Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init) or [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) to bootstrap the example:
The `PREPRIO_PREVIEW_KEY` can be any random string (but avoid spaces), like a UUID`, this is used
for [Preview Mode](https://nextjs.org/docs/advanced-features/preview-mode).
### Step 4. Run Next.js in development mode
```bash
npm install
npm run dev
# or
yarn install
yarn dev
```
Your blog should be up and running on [http://localhost:3000](http://localhost:3000)! If it doesn't work, post on [GitHub discussions](https://github.com/vercel/next.js/discussions).
### Step 5. Try preview mode
In Prepr, go to one of the posts in your environment and:
- **Update the title**. For example, you can add `[REVIEW]` in front of the title.
- After you edit the publication save the post with a review state.
To view the preview, transform the url to the following format: `http://localhost:3000/api/preview?secret=<YOUR_SECRET_TOKEN>&slug=<SLUG_TO_PREVIEW>` where `<YOUR_SECRET_TOKEN>` is
the same secret you defined in the `.env.local` file and `<SLUG_TO_PREVIEW>` is the slug of one of the posts you want to preview.
You should now be able to see post that are in Review and Done state. To exit the preview mode, you can click on _"Click here to exit preview mode"_ at the top.
### Step 6. Deploy on Vercel
You can deploy this app to the cloud with [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
#### Deploy Your Local Project
To deploy your local project to Vercel, push it to GitHub/GitLab/Bitbucket and [import to Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example).
**Important**: When you import your project on Vercel, make sure to click on **Environment Variables** and set them to match your `.env.local` file.
