kli

kommand line interface

The KDK CLI (a.k.a. kommand line interface or kli) is a multiplexer for usual git/yarn commands initially created to develop KDK-based applications more easily. It allows to quickly clone, install, link, unlink, switch branch on all modules and applications using a single command. It can be used by any project requiring to manage a dependency tree between different NodeJS modules stored in git repositories.

Concepts

The CLI relies on a workspace file defining the dependency tree between your (KDK-based) application and modules like this:

module.exports = {
  kdk: {
    dependencies: [],
    branches: ['master', 'test']
  },
  kApp: {
    application: true,
    dependencies: ['@kalisio/kdk'],
    branch: 'master'
  }
}

Each key is a git repository, i.e. a module, monorepo or application, with the following available properties:

Property Description
dependencies List of dependent (KDK-)based modules if any
branch Branch the module should be forced on whatever the target branch of the CLI
branches List of branches the module is available on (if the target branch of the CLI is not included it will be skipped)
application Indicates if this is the main KDK-based application module, i.e. it has an api subfolder
path Relative path to the repository on the local disk
organization GitHub/GitLab organization the repository belongs to
output Name of the repository folder on the local disk
url Root URL to the remote git repositories (if not given will be https://github.com)

TIP

The branch option can also target a git tag, typically fo production releases.

Installation

Prerequisites

Before you continue, you need to make sure that the following tools are installed on your system:

  1. Git
  2. Node
  3. Yarn

Production mode:

npm install -g @kalisio/kli

Development modes

To use the master branch locally:

git clone https://github.com/kalisio/kli.git
cd kli
yarn install
yarn link

Usage

By default, all operations will take effect in the current working directory so that subdirectories named according to modules will be created or expected to already exist.

// Will clone all repositories
kli workspace.js --clone
// Will install dependencies in all modules and application
kli workspace.js --install
// Will perform link between required modules and application
kli workspace.js --link
// Will perform unlink between required modules and application
kli workspace.js --unlink
// Will perform branch switching on all modules and application having the given target branch
kli workspace.js --branch test
// Will perform branch switching on all modules and application using the specified branch in workspace
kli workspace.js --switch

WARNING

By default all git operations target the kalisio organization, you can change this for the whole workspace using the organization CLI option or on specific modules only using the organization option in the workspace file. Like this you include modules coming from a separate organization but used as dependencies of the project owned by the main organization of the project.

WARNING

All operations are performed relative to the CWD by default, you can change this for specific modules only using the path option in the workspace file providing a module path relative to the CWD or absolute. Like this you can for instance have modules coming from a separate organization isolated into their own directory.

INFO

Sample workspaces are provided in this repository.

Full CLI usage is the following:

Usage: index <workspacefile> [options]

Options:
  -V, --version                      output the version number
  -o, --organization [organization]  GitHub organization or GitLab group owing the project (default: "kalisio")
  -u, --url [url]                    Git server base URL (default: "https://github.com")
  -c, --clone [branch]               Clone git repositories (with optional target branch) for all modules
  -p, --pull                         Pull git repositories for all modules
  -i, --install                      Perform yarn install for all modules
  -l, --link                         Perform yarn link for all modules
  -ul, --unlink                      Perform yarn unlink for all modules
  -b, --branch <branch>              Switch to target git branch in all modules where it does exist
  -s, --switch                       Switch all modules to the default git branch specified in workspace (if any)
  -m, --modules <modules>            Comma separated list of modules from the workspace to apply command on
  -h, --help                         output usage information

To enable verbose output for debugging use this before running it:

export DEBUG=kli*

Tips

Working on multiple versions

In order to be able to switch easily between different versions of NodeJS you usually use a version manager like n/nvm under Linux/Mac or nvm under Windows. However, as links are global to a Yarn installation it can be tricky to switch between different versions of the same repository using different NodeJS versions, e.g. KDK on master branch running under NodeJS v12 and KDK on another branch running under NodeJS v16.

Although you can have a single local KDK repository and switch between the branches we do not recommand it. Indeed, each time you will switch you will also have to reinstall all the dependencies for the new NodeJS version, which can be cumbersome and has proven to be error-prone for package managers. Moreover, the branch names between the different repositories in a complex architecture might not be consistent. Last but not least, sometimes the repositories themselves might change their names or location between different versions.

In a nutshell, we recommand creating a different workspace for your application and clone each repository in a different folder for each version. This way it is far more easier to switch from one version to another, before switching to a new version you simply need to unlink the previous version workspace:

// We are currently using NodeJS v12
cd nodejs12
kli workspace-nodejs12.js --link
...
// Start working with NodeJS v16
kli workspace-nodejs12.js --unlink
nvm use 16.0.0
cd nodejs16
kli workspace-nodejs16.js --link

Aliasing the KLI

When installing the KLI in development mode, it could be useful to create an alias, e.g. in your .bashrc, to use it:

alias kli="node Path/to/kli/index.js"
