Examples

beachball publish -r http://localhost:4873 -t beta

Notes

Overriding concurrency

In large monorepos, the process of fetching versions for sync or before publishing can be time-consuming due to the high number of packages. To optimize performance, you can override the concurrency for fetching from the registry by setting options.npmReadConcurrency (default: 5). You can also increase concurrency for hook calls and publish operations via options.concurrency (default: 1; respects topological order).

API surface

Beachball does not have a public API beyond the provided options. Usage of private APIs is not supported and may break at any time.

If you need to customize something beyond what's currently supported in the options, please open a feature request or talk with the maintainers.

AI integration

Normally, Beachball uses an interactive CLI prompt for generating change files. Since this doesn't work for AI agents, we have a change file skill with manual instructions.
