Submodule version

Git Submodule Version tool

Submodule version is a tool to manage git submodules as versioned packages.

This tool designed to split projects in-to submodules without npm-packages headache.

With submodule version code can be organized like a single monorepo, but each submodule can be easily reused in another projects like npm-package.

Problem to solve

Take a look on the next situation:

• Project has 2 submodules ui-button-element and render-engine
• Package ui-button-element dependents on the render-engine
• Third repo ui-slider-element dependets on newest version of the render-engine and not included in the project

This cause next problems:

• Add submodule ui-slider-element cause difficulties with handle different render-engine versions
• Manual swithing branches in submodules with big codebase can confuse
• Updated ui-button-element with new version of render-engine should be used in another project with the same version

Submodule version helps to

• Handle which project should be updated and which version should be installed
• Help update submodules and theirs dependencies
• Install new submodules

Installation

• Install sv tool npm i -D submodule-version
• Add workspaces section in package.json

    "workspaces": [
        "modules/*"
    ],

• Install first submodule npx sv i <git_repo>
• Install npm dependencies npm i. Submodule will be linked in node_modules and its dependencies will be installed
• Use your submodule in code import submodule from 'submodule-name' 🔥

How it works

• Each submodule and main project has own package.json with sv object inside. sv object will be generated automatically and will contain every dependency version

  "sv": {
      "[email protected]:guljeny/submodule-version.git": "^1.0.0"
  }

• Each submodule has a version tags, and sv use list of this tags to resolve dependencies
• Submodule version creates a graph of whole project and install only possible and actual versions

Versioning

Sumodules without specified version tags will be installed with ref to the latest commit. You should manage them manually.

To add new version in submodule:

• Specify version in package.json
• Add and push git tag with the same version (git tag 1.0.1)

Commands

• npx sv validate - Validate all dependencis and install missing modules
• npx sv install <git_url> [target_submodule] - Install new dependency
• npx sv update - Update all dependencies to the latest possible versions
• npx sv help - Description of all commands

Submodule dependencies

Sumbodules can contains their own dependencies specified in package.json as sv object.

To install submodule in submodule run npx install <git_url> [target_submodule]
