Shell

This project is a bootstrapper for downloading, setting up, and running a Node.js application. It automates the process of fetching the latest version of an app from a remote URL, unzipping it, installing dependencies, and starting the app.

Features

• Automatically downloads the latest version of the app.
• Cleans up old versions before setup.
• Installs dependencies and starts the app.
• Compares the current app version with the latest version to decide whether to update.

Setup

Prerequisites

• Node.js and npm installed on your system.
• Ensure you have access to the URLs specified in the .env file.

Steps

1. Clone this repository:

   git clone <repository-url>
   cd shell

2. Install dependencies:

   npm install

3. Configure the .env file (see below for details).

4. Start the bootstrapper:

   npm start

Configuring the .env File

The .env file contains environment variables required for the app to function. Below is an explanation of each variable:

• APP_URL: The URL to download the zipped Node.js app.
• INFO_URL: The URL to fetch the latest version information of the app.
• FILE_NAME: The name of the downloaded zip file.
• FOLDER_NAME: The name of the folder extracted from the zip file.

Example .env

APP_URL="https://example.com/dev/simple-nodejs-app-master.zip"
INFO_URL="https://example.com/dev/simple-nodejs-app-master-info.json"
FILE_NAME="simple-nodejs-app-master.zip"
FOLDER_NAME="simple-nodejs-app-master"

Info Template

The info-template.json file is used to define the structure of the version information fetched from the INFO_URL. Below is an example:

{
  "version": "2.0"
}

This file ensures that the app can compare the current version with the latest version available remotely.

Troubleshooting

• If the app fails to start, ensure the .env file is correctly configured.
• Check your internet connection if the app cannot download the zip file.
• Ensure Node.js and npm are installed and accessible in your system's PATH.
