How does Astro use data to optimize incremental builds?

Astro tracks which data files or sources changed and rebuilds only the pages or components that depend on that data, making builds faster and more efficient.

beginner

Which file types or data sources typically trigger incremental builds in Astro?

Changes in markdown files, JSON, API data, or any content files used in pages can trigger incremental builds for only affected pages.

beginner

Why are incremental builds important for large Astro projects?

Because rebuilding the entire site can take a long time, incremental builds speed up development and deployment by only updating what changed.

How can you ensure Astro correctly detects data changes for incremental builds?

By properly importing or referencing data files in your components or pages, Astro can watch those files and rebuild only affected parts when data changes.

What does Astro rebuild during an incremental build?

A The entire website every time

B Only pages or components affected by changed data

C Only CSS files

D Only JavaScript files

Astro rebuilds only the parts of the site that depend on changed data, saving time.

Which of these can trigger an incremental build in Astro?

A Opening the browser

B Changing a CSS variable only

D They rebuild everything twice

Incremental builds save time by rebuilding only what changed.

How does Astro know which pages to rebuild after data changes?

A By user manual selection only

B By guessing randomly

C By rebuilding all pages every time

D By tracking data imports and dependencies in pages

Astro tracks which pages use which data to rebuild only affected pages.

What should you do to help Astro detect data changes for incremental builds?

A Import or reference data files properly in your components

B Avoid using any data files

C Only use inline data in HTML

D Disable incremental builds

Proper data imports let Astro watch files and rebuild affected parts.
