@s54a/init || TempLate CLI || Project Initializer

When I was starting a new project, I used the 'create vite app' command. Then, I began to remove and add files for the project. It struck me that I could create it once and paste it everywhere when I start a new project. Thats how I started building this.

There are two branch of this project in this one I have removed images & a few files to reduce the size

Visit the Github Readme to see examples

How it Works

The package stores Templates inside a folder called "Templates" then when you run the init command it displays the templates and then it will paste the folder at the location where the terminal is open.

Simply it just copies & pastes the Folders from one place to another

Folder Structure

📁 init
├── 📁 templates
│   └── 📁 templateTest
│       ├── 📄 index.html
│       ├── 📄 main.js
│       └── 📄 style.css
├── 📄 index.js
├── 📜 LICENSE
├── 📝 Readme.md
└── 📋 package.json

For testing purposes, only one template has been included, consisting of three files (HTML, CSS & JS). Additional templates have not been added to avoid making the package unnecessarily large.

(Note ChatGPT built this folder structure)

Installation

This package provides an Executable Command

You will have to install this package globally to be able to use the init command.

npm install -g @s54a/init

Usage

To begin, open a terminal at the desired project location and run this command

init

This displays all available templates from the template folder, listed by folder name. Choose a template and enter the desired folder name when prompted to create a new project with the selected template's contents.

Users can also create templates themselves by running:

init -a "C:\Users\{User}\Desktop\Projects\Ongoing Projects"

Upon execution, the tool generates a new folder path containing the contents of the user-created template. Subsequently, when the init command is invoked, it showcases the recently created template under the specified name.

Tip: For Windows users, you can quickly access the folder by selecting it and then pressing ctrl + shift + c.

By Default when you create a Template it skips the node_modules folder and its contents.

But for reason you want to create a template with node_modules folder you will have to pass the -y flag.

init -a "O:\test\cliTest" -y

Templates can be removed using the following command:

init -r "template name"

(Note: The name must match exactly.)

Templates can also be added from GitHub with:

init -c "https://github.com/user/repoitoryName.git"

This process involves cloning the repository into the current terminal directory, removing the .git folder from the cloned repository, executing the init -a "repoName" command to create a copy in the templates folder, and then deleting the cloned repository folder from the current terminal location.

I have used this Regex to verify if the given string is a link or not.

const urlRegex =
  /^(https?|ftp):\/\/(([a-z\d]([a-z\d-]*[a-z\d])?\.)+[a-z]{2,}|localhost)(\/[-a-z\d%_.~+]*)*(\?[;&a-z\d%_.~+=-]*)?(\#[-a-z\d_]*)?$/i;

The reason it performs all these steps is because I attempted to accomplish it in a simpler manner but couldn't find one.

To see all the Commands (Help)

init -h

This a similar project built with Typescript https://github.com/pongsatt/mycli/blob/master/src/index.ts

Read this if you are a beginner

I asked one of my friend who is a beginner in Web Dev. She asked me a question how will I make templates or why use this instead of Copy Pasting

So when ever you do

npm create-react-app ProjectName

npm create-vite-app ProjectName

These files are generated (with create react app)

my-app/
├── README.md
├── node_modules/
├── package.json
├── .gitignore
├── public/
│   ├── favicon.ico
│   ├── index.html
│   ├── manifest.json
│   └── robots.txt
└── src/
├── App.css
├── App.js
├── App.test.js
├── index.css
├── index.js
└── logo.svg

As you can see there are so many files which aren't necessary so you will have to remove these files remove code from index.css or maybe more files.

So you can do this once and use this template by using this package or just copy paste.

So why use this package instead of copy pasting So assume you have created many templates now you will create a folder to store them and every time you will start a new project you will have to go to that location copy that file and paste it at the location where you are starting the project and then change the name.

So this package does all that when you create a template and add it as a template from Command Line Interface and what I have learned & heard is that you will much faster at things with CLI then GUI.

Why I Created this

When you start Learning to code you will create multiple new projects so every time you will have to create new files

e.g. index.html, style.css, app.js

When you will advance to React you will do

So every time you will do that you will have to remove files edit content of the files.

So I thought it is a hassle so lets just do it once and I wil copy & paste it every time whenever I start a new project.

Then I thought I can create a cli which does that for me & I started building this package.

Then on a suggestion of a friend I also added the Clone & Create Template from Github Feature.

How I use this Package

I use this Package whenever I start a new project.

I have created my own template and added them as templates using init -a "folder path" command.

I have also added templates on Github.

So if I am on a new device or format my current one so I can just run the init -c "github_url" command after installing the package to clone new project and create a new template.

So if you are a Freelancer or Someone who is learning to code, or starting a new Project you can use this.

Extra Info

While Deploying Packages on NPM I realized that whatever you have in your project will get included even if you use npm ignore. I don't know if npm ignore works or failed. So I created another branch of this project in which I removed images and extra files. To reduce the size of the package & the node_modules size.

Here is the difference

So the Packa`ge Size is reduced by 300 Kilo Bytes

Source Code

Every time when I look at the open source I feel it is a hassle to navigate around files to see the code.

And this project source code is in a single file.

So I am adding the source code in the markdown file so you can read it all in one place.
