ScriptForm

About

A stand-alone webserver that automatically generates forms from JSON to serve as frontends to scripts.

ScriptForm takes a JSON file which contains form definitions. It then constructs web forms from this JSON and serves these to users. The user can select a form and fill it out. When the user submits the form, it is validated and the associated script is called. Data entered in the form is passed to the script through the environment.

Example

The following example lets you add new users to a htpasswd file via ScriptForm. It presents the user with a form to enter the user's details. When the form is submitted, the job_add_user.sh script is called which adds the user to the htpasswd file.

Form definition file: test_server.json

{
  "title": "Test server",
  "forms": {
    "add_user": {
      "title": "Add user",
      "description": "Add a user to the htpasswd file",
      "submit_title": "Add user",
      "script": "job_add_user.sh",
      "fields": [
        {"name": "username", "title": "Username", "type": "string"},
        {"name": "password1", "title": "Password", "type": "password"},
        {"name": "password2", "title": "Repeat password", "type": "password"}
      ]
    }
  }
}

The script job_add_user.sh:

#!/bin/sh

if [ -z "$password1" ]; then
    err "Empty password specified" >&2; exit 1
fi
if [ "$password1" != "$password2" ]; then
    err "Passwords do not match" >&2; exit 1
fi

htpasswd -s -b .htpasswd $username $password1 || exit $?

We can now start ScriptForm to start serving the form over HTTP:

$ scriptform -p8080 ./test_server.json
