cnsh

cnsh is a lightweight package manager that provides a minimal alternative to Yarn. It fetches packages from the npm registry and installs them in a simplified directory structure.

Features

• Add Packages: Install packages from the npm registry.
• Remove Packages: Uninstall packages from your project.
• Install Dependencies: Install all dependencies listed in package.json.
• Global and Local Installation: Supports both global and local package management.
• Simple and Efficient: Focuses on essential features for ease of use.

Installation

To install cnsh globally, follow these steps:

1. Install via npm

   Run the following command in your terminal:

   npm install -g cnsh --verbose

   This will install cnsh globally, making it available from any directory on your system.

2. Verify Installation

   To check if cnsh is installed correctly, run:

   cnsh <random-letters-and-numbers>

   For example:

   cnsh asdf1234

   If cnsh is installed, you should see the following output in red text:

   Unknown command. Use "add", "remove", or "install".

   This confirms that cnsh is properly installed and recognizing commands.

Usage

cnsh offers a simple set of commands for managing packages. Here’s how to use it:

Adding a Package

To add a package to your project, use:

cnsh add <package-name> --verbose

the verbose flag is optional, it is used to display more information

For example, to add lodash:

cnsh add lodash --verbose

This installs lodash into your project's cnsh_lib directory.

Updating

To update it, run this command in your terminal:

npm install -g cnsh@latest

Removing a Package

To remove a package, use:

cnsh remove <package-name>

For example, to remove lodash:

cnsh remove lodash

Installing Dependencies

To install all dependencies listed in your package.json, use:

cnsh install

This reads the package.json file and installs all listed dependencies into your cnsh_lib directory.

Global Installation

To install a package globally, use:

cnsh add -g <package-name>

Global packages will be installed in a global directory (typically ~/.cnsh-global/cnsh_lib).

Help

For a list of available commands and help, use:

cnsh --help

Note: Running unavailable commands will display the available commands. Since the help command itself is unavailable, it's kind of a win-win situation!

Example: Using axios with cnsh

Here’s a demonstration of how to use axios with cnsh:

1. Install axios

   cnsh add axios

2. Create a Simple Node.js Script

   Create a file named app.js with the following content:

   // Import axios from the local path where cnsh stores it
   import axios from './cnsh_lib/axios/package/dist/esm/axios.min.js';
   
   // Function to fetch data from a public API
   async function fetchData() {
       try {
           const response = await axios.get('https://jsonplaceholder.typicode.com/posts/1');
           console.log('Data fetched:', response.data);
       } catch (error) {
           console.error('Error fetching data:', error);
       }
   }
   
   // Call the fetchData function
   fetchData();

or if you like CommonJS better:

async function fetchData() {
    try {
        const axios = await import('./cnsh_lib/axios/package/dist/esm/axios.min.js');
        const response = await axios.default.get('https://jsonplaceholder.typicode.com/posts/1');
        console.log('Data fetched:', response.data);
    } catch (error) {
        console.error('Error fetching data:', error);
    }
}

fetchData();

UMD:

(function (root, factory) {
    if (typeof define === 'function' && define.amd) {
        // AMD
        define(['axios'], factory);
    } else if (typeof module === 'object' && module.exports) {
        // Node.js or CommonJS
        module.exports = factory(require('./cnsh_lib/axios/package/dist/axios.js'));
    } else {
        // Browser global
        root.fetchData = factory(root.axios);
    }
}(typeof self !== 'undefined' ? self : this, function (axios) {
    'use strict';

    // Function to fetch data from a public API
    async function fetchData() {
        try {
            const response = await axios.get('https://jsonplaceholder.typicode.com/posts/1');
            console.log('Data fetched:', response.data);
        } catch (error) {
            console.error('Error fetching data:', error);
        }
    }

    // Return the function as part of the UMD module
    return fetchData;
}));

// To call fetchData in a browser environment:
fetchData();

3. Run Your Script

   Execute your script using Node.js:

   node app.js

   You should see the data fetched from the public API printed to your console.
