Using semantic-release

semantic-release automates the package release workflow including: determining the next version number, generating the release notes, and publishing the package. This removes the immediate connection between human emotions and version numbers, strictly following the Semantic Versioning Specification and communicating the impact of changes to consumers.

MAJOR.MINOR.PATCH version numbering

Increment the:

• MAJOR version when making incompatible API changes,
• MINOR version when adding functionality in a backward compatible manner,
• PATCH version when making backward compatible bug fixes.

Rules for committing to development branch

| commit | release | next version | sample commit message | |-----------|---------|--------------|-----------------------------------------------------| | refactor: | patch | 1.0.0->1.0.1 | refactor: implement calculation method as recursion | | fix: | patch | 1.0.0->1.0.1 | fix: add missing parameter to service call | | docs: | patch | 1.0.0->1.0.1 | docs: update readme | | style: | patch | 1.0.0->1.0.1 | style: update readme | | test: | patch | 1.0.0->1.0.1 | test: update unit tes | | build: | major | 1.0.0->2.0.0 | build: upated look file | | ci | patch | 1.0.0->1.0.1 | ci: add new stage (integration test) | | revert | patch | 1.0.0->1.0.1 | revert: revert to commit | | feat: | minor | 1.0.0->1.1.0 | feat(lang): add Polish language | | chore: | minor | 1.0.0->1.1.0 | chore: drop support for Node 6 | | perf: | minor | 1.0.0->1.1.0 | perf: -//- |

Conventional Commits

• The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.

• The commit message should be structured as follows:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

• The commit contains the following structural elements, to communicate intent to the consumers of your library:

1. fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).

2. feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).

3. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.

4. types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the Angular convention) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others.
