Pull Request Formatting

This is a guide to formatting your pull requests.

This is adapted from Angular’s commit convention.


Messages must be matched by the following regex:

/^revert(Item): ?(chore|docs|feat|fix|perf|refactor|style|test)(\(.+\))?: .{1,72}/;

Known issues

husky hooks are currently not compatible with GitHub Desktop’s commit tool on Node 16+. There is an open issue about this on their repo, therefore there is nothing we can do about this. We recommend either committing through the command line, or using VSCode’s source control.


Appears under the “Features” header, Command subheader in a potential changelog:

feat(Command): add 'foo' command

Appears under the “Bug Fixes” header, Database subheader, with a link to issue #28 in a potential changelog:

fix(Database): handle caching

close #28

Appears under the “Performance Improvements” header, and under “Breaking Changes” with the breaking change explanation in a potential changelog:

perf(Server): improve patching by removing 'bar' option

BREAKING CHANGE: The 'bar' option has been removed.

The following commit and commit 667ecc1 do not appear in the changelog if they are under the same release. If not, the revert commit appears under the “Reverts” header.

revert: feat: Discussions (#4662)

This reverts commit c8cb81ec50aae940efa35ad3d69ee69c2db89125.

Full Message Format

A commit message consists of a header, body and footer. The header has a type, scope and subject:

<type>(<scope>): <subject>

The header and the subject are mandatory, while the scope of the header is optional.


If the commit reverts a previous commit, it should begin with revert:, followed by the header of the reverted commit. In the body, it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.


If the prefix is feat, fix or perf, it will appear in the changelog. However, if there is any BREAKING CHANGE, the commit will always appear in the changelog.

Other prefixes are up to your discretion. Suggested prefixes are chore, style, refactor, and test for non-changelog related tasks.


The scope could be anything specifying the place of the commit change, usually the name of a Vtuber. For example WebScript, Faq etc…


The subject contains a succinct description of the change:

  • use the imperative, present tense: “change” not “changed” nor “changes”
  • don’t capitalize the first letter
  • no dot (.) at the end


Just as in the subject, use the imperative, present tense: “change” not “changed” nor “changes”. The body should include the motivation for the change and contrast this with previous behavior.

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the phrase BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.
