What is API Extractor?

API Extractor generates an api.md file containing the public API for a package. @fluentui/react and related packages as well as @fluentui/web-components use API Extractor to ensure that API changes must be reviewed before being merged into master. (@fluentui/react-northstar and related packages do not use API Extractor as of writing.)

Build Tasks

As part of a package's build process, the api-extractor task checks the package's public API with the package's auto-generated .api.md file. Be sure to commit the updates with your other changes

In PR builds, the task will fail if it detects missing API file updates.

To generate the API markdown file commit your changes, then run:

yarn nx run <package-name>:build

Commit and push the updated file.
