Set the version key in lerna.json to independent to run in independent mode. (There is work on this already at atlassian/lerna-semantic-release). Combining this mode with something like semantic-release would make it less painful. Independent mode allows you to more specifically update versions for each package and makes sense for a group of components. Each time you publish, you will get a prompt for each package that has changed to specify if it's a patch, minor, major or custom change. Independent mode Lerna projects allows maintainers to increment package versions independently of each other. As a result, all package versions will stay synchronized to the version in lerna.json. This will force Lerna to always version and publish all packages, regardless of if they have changed since the previous release. To prevent this, use the -force-publish option with lerna version and lerna publish. Lerna will only version and publish packages that have changed since the previous release, causing package versions to drift apart over time. One issue with this approach is that a major change in any package will result in all packages having a new major version. Use this if you want to automatically tie all package versions together.

Because of that, running lerna publish with a major version zero and choosing any non-prerelease version number will cause new versions to be published for all packages, even if not all packages have changed since the last release. Note: If you have a major version zero, all updates are considered breaking. This means that you only publish a new version of a package when you need to.

When you run lerna publish, if a module has been updated since the last time a release was made, it will be updated to the new version you're releasing. The version is kept in the lerna.json file at the root of your project under the version key. Fixed/Locked mode (default) įixed mode Lerna projects operate on a single version line. Lerna allows you to manage your project using one of two modes: Fixed or Independent.
