next-ver

Tells you the next semantic version for your local package

Install and use

Imagine a local package with current version 2.3.0 and a single semantic commit fix(something): fix the login. This tools computes the next version that should be used.

npm install -g next-ver
next-ver
next version should be 2.3.1

Then you can publish, for example using npm version command or one of the good helper CLI tools, like publish-please, np or ci-publish.

npm version 2.3.1

Incrementing version in package file

If there is a new version, you can update the version in the "package.json" file and commit the change, including creating a tag, just like the command npm version <new version> does.

Just add --go to the next-ver command

next-ver --go

Semantic version rules

A semantic version has form "major.minor.patch"

A typical semantic commit has message of the form "type(scope): message". Commits that do not follow this format are ignored when computing next version.

If there is a commit fix(something): ... then new version should increment the "patch" number. A commit feat(something): ... will increment the "minor" number. Finally, a commit with text "BREAKING" anywhere in the message or the message body text will increment the "major" number.

When there are multiple numbers, the will be only the highest single digit increment. For example, these 4 commits will increment the "minor" number only.

fix(this): ...
fix(that): ...
feat(log): ...
feat(server): ...

CLI options

• --go increments the version in the current folder's package.json
• --version, -v shows the version of next-ver itself

I recommend enforcing commit message format using pre-git with its default simple-commit-message format validator. They work great with semantic-release tool.

• latest-version-or-tag is used to fetch NPM tags and compare latest to the version in package.json

Testing and development

Uses separate repo next-ver-test for testing this tool via dont-break
