# Configuration

For most uses you probably do not need any specific configuration on each package within your repository. But there are a few options to customize beachball's behavior.

There are two types of configurations:

  1. repository config
  2. package config

# Configuration Files

Each type of configuration can be specified one of several ways. The configuration of beachball is provided by cosmiconfig (opens new window), therefore, you can specify configuration in different kinds of files (and even as CLI arguments).

  • beachball key inside package.json
  • .beachballrc
  • .beachballrc.json
  • beachball.config.js

Be consistent! We encourage you to use the same convention within the same monorepo! When in doubt, just use beachball.config.js.

# beachball.config.js

By far the most flexible of these is, of course, the type of configuration written in JavaScript (exposed as a CommonJS module). We'll concentrate on this type of configuration.

module.exports = {
  key: value,
  key2: value2
  key3: value3

You can place these in either the root of a repo or within a package like so (package config overrides the repo configuration where applicable). For example:
