Commands:

Usage

There are two CLI commands: parse and ui.

Both commands can take input by file path (--file) or by STDIN.

Parse

The parse command reads in an NGINX config and writes out Ngindox YAML to STDOUT.

ngindox parse -f examples/nginx.master.conf > examples/nginx.master.yaml

Ngindox pays close attention to three commands in NGINX configs:

• upstream
• location
• root

These commands are parsed for their content, but may also be commented to annotate metadata that will be included in the Ngindox YAML and rendered in the Ngindox UI. For example:

# Group: Root
# Description: Static web content
root /path/to/html/files;

All comments immediately prior to parsed commands are assumed to be Ngindox metadata in YAML format, unless prefixed with an additional #. For example:

## This comment is freeform and ignored by Ngindox
# Group: Root
# Description: Static web content
root /path/to/html/files;

Another option for ignoring non-metadata is to use a YAML file delimiter (---) to prefix the metadata. For example:

# This comment is freeform and ignored by Ngindox
# ---
# Group: Root
# Description: Static web content
root /path/to/html/files;

UI

The ui command reads in an Ngindox YAML and writes out Ngindox UI HTML to STDOUT.

ngindox ui -f examples/nginx.master.yaml > examples/nginx.master.html

By default, the HTML output embeds <style> and <script> sections, including jquery.

Disable css and/or javascript by passing an empty string value to the respective option flags:

ngindox ui --css '' --javascript '' -f examples/nginx.agent.yaml > examples/nginx.agent.html

Piping

If no file is specified, input is expected on STDIN. This allows piping the intermediate Ngindox YAML without saving it to disk:

ngindox parse -f examples/nginx.agent.conf | ./cli.js ui > examples/nginx.agent.html

Note: Using STDIN for parsing disables file include expansion.
