Every time you commit new code to your Zola site, Cloudflare Pages will automatically rebuild your project and deploy it. You will also get access to [preview deployments](/pages/configuration/preview-deployments/) on new pull requests, so you can preview how changes look to your site before deploying them to production.

### Handling Preview Deployments

When working with Cloudflare Pages, you'll often use preview deployments for testing changes before merging to your main branch. However, these preview deployments use different URLs (like `https://your-branch-name.my-zola-project.pages.dev`), which can cause issues with asset loading if your `base_url` is hardcoded.

To fix this, modify your build command in the Cloudflare Pages configuration to dynamically set the base URL depending on the environment:

```sh
if [ "$CF_PAGES_BRANCH" = "main" ]; then zola build; else zola build --base-url $CF_PAGES_URL; fi
```

This command uses:
- The `base_url` set in `config.toml` when building from the `main` branch
- The preview deployment URL (automatically provided by Cloudflare Pages as `$CF_PAGES_URL`) for all other branches
