Editors

Visual Studio Code

caddy json-schema --vscode generates Visual Studio Code configuration in the current directory.

Open the directory in Visual Studio Code and it should just work. Ensure the config filename is of the format *caddy*.[json|yaml].

Note that you need vscode-yaml plugin to get similar experience for YAML files.

Vim/NeoVim

There are multiple Vim/NeoVim plugins with language server and JSON schema support.

Below is a config for coc-json and coc-yaml. The path to schema file is relative to the config file being edited.

{
  "json.schemas": [
    {
      "fileMatch": ["*caddy*.json"],
      "url": "./caddy_schema.json"
    }
  ],
  "yaml.schemas": {
    ".vscode/caddy_schema.json": ["*caddy*.yaml", "*caddy*.yml"]
  }
}
