Repositories

Chronos supports multiple repositories, both local and Git based. This allows you to have a single server for multiple projects or multiple repositories for a single project.

Repositories can be configured in the chronos.json file as follows:

{
  "port": "8080",
  "gitRepos": [
    {
      "id": "vosDocs",
      "url": "https://github.com/Vanilla-OS/documentation"
    },
    {
      "id": "vosVib",
      "url": "https://github.com/Vanilla-OS/vib",
      "rootPath": "docs/articles"
    }
  ],
  "localRepos": [
    {
      "id": "myAwesomeProject",
      "path": "/myAwesomeProject/documentation"
    }
  ]
}

Each repository must have a unique id, Chronos requires it to identify the repository when requesting articles.

Local repositories

Each local repository must contain an articles folder with the following structure:

documentation
├──articles
├─── en
│    └─── article1.md
└─── it
     └─── article1.md

Git repositories

You can use a Git repositories as well, just add them to the GitRepos array in the chronos.json file, Chronos will automatically clone them and update on each restart.

Background updates

In the current version, automatic updates are in experimental stage and are not yet fully implemented.
