Build Event Handlers overview
Build Event Handlers let your integration hook into the Netlify build process of a site that is using your integration. The old way of doing this was through Netlify Build Plugins. Build Event Handlers are only active on a site level (learn more about integration levels)
Build Event Handlers expand what Netlify builds are capable of. For example, Build Event Handlers allow you to:
- speed up builds by optimizing and debugging your build cache
- import and convert data from external sources
- check for broken links in a site after building
- analyze and optimize site asset handling for better runtime performance
- generate content like sitemaps, RSS feeds, and search indexes
You can use the Netlify SDK utility tools to run, test, and build your integration as you work.
Once you publish your integration, it will be available for Netlify users to add to their sites or teams.
