Introduction

As backend and frontend are decoupled, the components maintain their individual version numbers. DCP uses 3 digit versioning following the semantic versioning approach. Documentation updates for individual builds are not maintained.

Frontend versioning

Package versions of an individual app is maintained inside the package.json of the individual app. During build, the file fe-module-versions.json file on the document root needs to be updated. This file contains all active/currently deployed frontend version numbers. The update is happening automatically inside continuous-integration. If needed individual frontend apps can consume the version numbers from the file at the document root.

Backend versioning

Backend versions are maintained using the conventions of the corresponding programming language (.NET uses the AssemblyProperties.cs file). Every backend app needs to implement an endpoint returning the version number. The version endpoint should be exposed at /api/Version/GetBEVersion.

Branching strategy

In DCP we use 3 main branches:

• develop branch for new development
• test branch for automation testing
• main branch for Production deployment

Also, we use two secondary branches:

• stage branch for stable environment that can be used for automation test development
• education branch that is used as a training environment
