use Angular commit guidelines

it wil be much helpful to create changeLog

• feat: A new feature
• fix: A bug fix
• docs: Documentation only changes
• style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
• refactor: A code change that neither fixes a bug nor adds a feature
• perf: A code change that improves performance
• test: Adding missing tests
• chore: Changes to the build process or auxiliary tools and libraries such as documentation generation
