Action Cable CLI

ACLI is an Action Cable command-line interface written in mRuby.

It's a standalone binary which can be used:

In development for playing with Action Cable channels (instead of struggling with browsers)
For monitoring and benchmarking.

Installation

Currently only MacOS (x86_64 and ARM) and Linux (x86_64) are supported. PRs are welcomed for other platforms support.

Usage

ACLI is an interactive tool by design, i.e., it is asking you for input if necessary. Just run it without any arguments:

$ acli

Enter URL:

# After successful connection you receive a message:
Connected to Action Cable at http://example.com/cable

Then you can run Action Cable commands:

# Subscribe to channel (without parameters)
\s channel_name

# Subscribe to channel with params

\s+ channel_name id:1

# or interactively

\s+
Enter channel ID:
...
# Generate params object by providing keys and values one by one
Enter key (or press ENTER to finish):
...
Enter value:
# After successful subscription you receive a message
Subscribed to channel_name


# Performing actions
\p speak message:Hello!

# or interactively (the same way as \s+)
\p+


# Retrieving the channel's history since the specified time

# Relative, for example, 10 minutes ago ("h" and "s" modifiers are also supported)
\h since:10m

# Absolute since the UTC time (seconds)
\h since:1650634535

You can also provide URL and channel info using CLI options:

acli -u http://example.com/cable -c channel_name

# or using full option names
acli --url=http://example.com/cable --channel=channel_name

# you can omit scheme and even path (/cable is used by default)
acli -u example.com

To pass channel params use --channel-params option:

acli -u http://example.com/cable -c ChatChannel --channel-params=id:1,name:"Jack"

You can pass additional request headers:

acli -u example.com --headers="x-api-token:secret,cookie:username=john"

Other commands:

# Print help
\?

# Quit
\q

Other command-line options:

# Print usage
acli -h

# Print version
acli -v

# Quit after M incoming messages (excluding pings and system messages)
acli -u http://example.com/cable -c channel_name --quit-after=M

# Enabling PONG commands in response to PINGs
acli -u http://example.com/cable --pong
