Webalizer
Intro
Webalizer is a web interface for running local programs and scripts remotely.
It is implemented as a command line application that reads command definition configurations and exposes those commands with a simple, easy to use UI. I use it for running tasks and scripts in my home server.
Despite it has authentication and I do my best to make it as secure as possible, it is intended to be used in a trusted environment, such as your home network and not directly exposed to the internet. Be careful. This is just a side project.
Here is a screenshot:
Installation
Ensure you have a recent version of node and npm, then:
npm i -g webalizer
Configuration
By default, webalizer will look for command definition files at
~/.webalizer/*.json
where each .json
file represents the configuration for a
single command in the web interface. Here is an example configuration file which
you can create for example at ~/.webalizer/start_vm.json
:
{
"command": "VBoxManage startvm Windows --type headless",
"name": "Start windows VM",
"description": "Starts the windows VM",
"button": "Start",
"shell": true,
"confirm": "Are you sure you want to start this VM?",
"timeout": 5000
}
The following configuration options are available:
command: Required. Actual program or shell script to run. Note that if your
command depends on any shell feature, you will need to set also shell: true
for it to work correctly.
name: Required. Name of this script to be shown in the UI
description: Optional. An explanatory description of what this command does.
button: Optional, defaults to "Run". Label the button for running this command will have in the UI
shell: Optional, defaults to false
. If set to true, the command
will be
run inside a shell. warning This might be more insecure than running just a
program. Use with caution.
confirm: Optional, defaults to false
. If set to true
, it will prompt for
confirmation with a default message when the user clicks the button to run the
command. If set to a non empty message, it will show this message to the user
instead of the default one
timeout: Optional, defaults to 1 minute. Maximum time for the script to run. After this time is reached, the script will be killed.
Running
ADDRESS=0.0.0.0 PORT=8088 USERNAME=someuser PASSWORD=somepass NEXTAUTH_URL=http://yourPublicServerAddressOrIP:8088 webalizer
The following environment variables are available:
ADDRESS: Optional, defaults to 127.0.0.1. IP address where the web application will listen for connections
PORT: Optional, defaults to 3000. Port where the web application will listen for connections
USERNAME: Optional. if this and the PASSWORD options are set to non empty values, the application will ask for logging in.
PASSWORD: Optional. if this and the USERNAME options are set to non empty values, the application will ask for logging in.
NEXTATUH_URL: Optional, only required if USERNAME and PASSWORD are set. Public URL you will use to reach your application.
SCRIPTS_ROOT: Optional, defaults to ~/.webalizer
. Directory where to look
for command definition files.

You can optionally customize development time env vars by doing
cp .env.example .env
and customizing the values in .env
To run tests:
npm test
