Tool to track dependncies of software-projects

Metrics

• Lines of source and Number of files per category

  • Test
  • Examples
  • Functionality

• Resulting optimized binary size of the functionality including runtime-dependencies

• Total install-size of dev-dependencies in Bytes (on top of alpine-linux docker image) -> Pushed to docker registry

• Total install-size of external-dependencies -> Use docker image size if available

• Number of service dependencies (size cannot be calculated)

• Add file to repo -> Dockerfile.ruler

• Use resulting docker image sizes for dev-dependencies and total optimized binary size with runtime

• Cound lines of code / source lines based on three categories via simple tool

Dependency types

Dev-dependencies

• Everything a contributor needs to install in order to contribute to the project
• Typical examples: Testing frameworks, "devDependencies" section in package.json, build systems, compilers

Runtime-dependencies

• Everything the user of a software component needs in order to use/run the component/application

External-dependencies

• Software artifacts that do not reside in the same process (memory-address-space) of the component (e.g. databases, web-services, CDNs)

Service-dependencies

• Software that is not available as source-code nor binary and can therefore not be measured except for its existence

Implicit-dependencies

• e.g. operating system, are currently not measured

Goals

• Manuals / best-practices to cont. measure and track the above mentioned metrics
• Automated tooling to retrieve these metrics
• Visualize the results for some open-source projects
• Easy to use and integrate into existing projects -> Badges based on github repo urls
• simple-go binary instead of bash script that calls docker history to export layer sizes + does line counting for the actual code.

Non-goals

• https://dependencytrack.org/
• Building the docker images on separte infrastructure -> use what is already there.
