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:

Ensure you have a recent version of node and npm, then:

npm i -g webalizer

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.

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.

Clone this repository, and then:

npm install
npm run dev

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
