# Version Groups

By default, all packages in the repository are versioned based solely on the changes as specified by the change files. Developers are expected to create these change files along with the bump type for the packages as they go.

Some projects require bumping versions together so that the consumers really only need to remember one single version number when bumping related packages. The most famous of this strategy is Babel that versions all their related packages together with the locked step versioning.

beachball strives to be automated and flexible, so it provides a concept of version groups. Whenever one of the packages of one of the packages inside a group is bumped, the entire group's packages will get bumped the same way.

Note: a package cannot belong to multiple groups - beachball will not allow its commands to work with that configuration

# Configuring groups

In the configuration section, we discussed how to configure beachball. Here's an example of a config file named beachball.config.js:

module.exports = {
  bumpDeps: true,

We can add a group by adding it to the configuration like this:

module.exports = {
  bumpDeps: true
+ groups: [
+   {
+      name: "group name",
+      include: ["packages/groupfoo/*"],
+      exclude: ["packages/groupfoo/bar"]
+   }
+ ]

beachball uses minimatch to match which packages belong to which group via this configuration. In the above configuration, packages located inside packages/groupfoo would be bumped together.

NOTE: Beachball does not guarantee currently that these packages have the same version number, but that it will be bumped at the same rate. This is an area of active development, so please consider submitting feature request issues to change its behavior with justifications
