Redoc CLI commands

The CLI includes the following commands:

redoc-cli serve [spec]: Starts a local server with Redoc. You must include the required parameter, spec, which is a reference to an OpenAPI definition. Options include:
- --ssr: Implements a server-side rendering model.
- --watch: Automatically reloads the server while you edit your OpenAPI definition.
- --options: Customizes your output using Redoc functionality options or Redoc theming options. To add nested options, use dot notation.
redoc-cli build [spec]: Builds spec and Redoc into a zero-dependency HTML file. Options include:
- -t or --template: Uses custom Handlebars templates to render your OpenAPI definition.
- --templateOptions: Adds template options you want to pass to your custom Handlebars template. To add options, use dot notation.
--help: Prints help text for the Redoc CLI commands and options.
--version: Prints the version of the redoc-cli package you have installed.

Redoc CLI examples

Bundle

Bundle with the main color changed to orange:

redoc-cli build openapi.yaml --options.theme.colors.primary.main=orange

Bundle using a custom Handlebars template and add custom templateOptions:

redoc-cli build http://petstore.swagger.io/v2/swagger.json -t custom.hbs --templateOptions.metaDescription "Page meta description"

Sample Handlebars template:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf8" />
        <title>{{title}}</title>
        <!-- needed for adaptive design -->
        <meta description="{{{templateOptions.metaDescription}}}">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <style>
            body {
            padding: 0;
            margin: 0;
            }
        </style>
        {{{redocHead}}}
        {{#unless disableGoogleFont}}<link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,700|Roboto:300,400,700" rel="stylesheet">{{/unless}}
    </head>
    <body>
      {{{redocHTML}}}
    </body>
</html>
