Git Flow

We use the simplified git-flow to improve team development speed. Unlike the standard git-flow, we don't have a release branch.

When a feature branch is finished, you must submit a Pull Request to develop branch.

Don't forget assign your partner to review it.

App Version

The App Version use Semantic Versioning concept.

The Semantic Versioning concept is simple: all versions have 3 digits: x.y.z.

• the first digit is the major version
• the second digit is the minor version
• the third digit is the patch version

When you make a new release, you don’t just up a number as you please, but you have rules:

• up the major version when you make incompatible API changes
• up the minor version when you add functionality in a backward-compatible manner
• up the patch version when you make backward-compatible bug fixes

npm version [major|minor|patch] --no-git-tag-version
