Why we need to use angular cli? - angularjs

Hello everyone I want to learn angular, but I am bit confused like what is the use of angular cli??
Why I need to write 3 different files like app.html, app.component.ts and app.module.ts instead of writing code in those three files can't we use angular cdn directly? How better that component based architecture will work?
Please do not laugh at me I am new to this topic so previous are random questions that came to my mind while surfing the internet.

Angular CLI stands for Angular Command Line Interface (see this link). As the name implies, it is a command line tool for creating angular apps. It is recommended to use angular cli for creating angular apps as you don't need to spend time installing and configuring all the required dependencies and wiring everything together.
The Angular CLI is used for much more than just creating an Angular project. It can be used to create components, services, pipes, directives and more. Also it helps in building, serving, testing etc. CLI itself is quite something to learn about, it makes Angular development workflow much easier and faster.

I will try to provide little more thorough answer on this and give a few examples too.
First of all, Angular CLI is a command-line interface tool that you use to initialize, develop, scaffold, and maintain Angular applications directly from a command shell. It saves you from the hassle of complex configurations and build tools like TypeScript, Webpack, and so on.
After installing Angular CLI, you’ll need to run one command to generate a project and another to serve it using a local development server to play with your application.
Here are a few basic and useful commands that show the benefit of using it:
ng help
ng generate --help
ng new my-first-project
cd my-first-project
ng serve
For more commands info and their full explanation refer to the official documentation here: Angular CLI Official Page.
You do not have to use Angular CLI in order to create and run and develop Angular apps, but isn't it best to use "GG" electric socket covers with "GG" frames for those covers?

Angular cli can ease you work setting up maintain and customize your angular projects. Here are some of the main reasons you should use it:

Does Nuxt and React have a GUI like Vue CLI3 that includes a convenient template generation wizard and build button?

I have made several products with Vue CLI 3.
However, I have never created a new project using Nuxt.
I am also interested in React because its market share is high.
However, I have never created a new project.
The reason is that I'm used to the convenience of Vue CLI 3.
Convenient template creation wizard
GUI with build buttons
I like the environment that exists.
For me, too much freedom in naming and arranging files is a problem.
I can't decide on the best one, so I can't develop fast.
There are two things I expect from Nuxt and React:.
$ vue create my-project
$ vue ui
Do Nuxt and React currently have those features?
If it does not exist,
Please tell me how you solve it.
If you have used vue cli then I'm pretty sure you can use nuxt's create-nuxt-app
It is easy just as it seems. The cli will guide you throughout the initialization process.

What barebone set up for developing web apps in angularjs?

I know its base on what you need, but in bare minimum what would be the best start up frameworks, task runners, plugins etc to develop real world web application? Im a noob but I think Il set it up as using:
Npm, angularjs ,jquery, expressjs, grunt, bower, bootstrap?
Then you just check which plugin you need for particular job?
Because alot of tutorials are pretty focus on just the angular side of things but never a real world development environment that could help with the job.
And follow up question is it advisable to have a dst and src folder and when youre done put everything in dst? What would be your take on this matter? Thank you
And for your question, I would suggest Angular CLI. It creates all the boilerplate to start coding in Angular, including task manager with all most all the tasks you need, CSS and boiler plates, etc.. It even has a command-line interface which would help you create components, classes, services, etc of your app from the terminal.

Creating multi project application

I'm new to Aurelia and I want to create an app that call for other apps.
Example : I want to create 3 projects, project A, project B and common and wish to call common in both projects A and B.
I've tried some examples with npm and others, but this never works.
Is there a simple way for doing that ?
Best way to utilize your common features for your 2 projects is to use an aurelia plugin.
Aurelia plugins are very good at encapsulting reusable components.
JSPM, the default package manager for Aurelia, supports private github repo and even local ones (easier during the early development phase).
So intalling your plugin in your project will be as easy as typing something like that :
jspm install github:mygithubaccount/myplugin#master
I would advise you to start reading one of plugin authoring blog post, then check the repo plugin to see how to package yours.
Check the blog post about AureliaFlux, it is worth reading.
You can also use the aurelia skeleton-plugin repository as a starting point.
Good luck.

Is there a way I can use angular-generator without yeoman?

Basically what I want is a scaffolding tool (without bower and other stuff that it comes with) and controller, service/factory generators.
Yeoman is great but I was wondering if there's anything minimalist cli out there for angular.
Well, if all you want is a base angular app structure, that is called a boilerplate. There are a few available:
https://github.com/angular/angular-seed
https://github.com/ngbp/ngbp
https://github.com/angular-app/angular-app
However, you seem to also want a controller, service/factory generator. This will always require:
some kind of task runner (like Grunt)
or an IDE that supports templates.
Since you don't seem to like grunt (grunt IS AWESOME), these IDEs might help you...
Eclipse supports template, you can find some here
IntelliJ's PHPStorm or WebStorm have a feature called Live Templates which, IMHO, are far better than eclipse. You can find some premade templates here, but is easy to roll your own, as explained in this tutorial.
If you want a command line interface but not Yeoman's, you might want to have a look at the "Generation" section of this collection. As of today, it has one option that uses Lineman and two that made their own CLI, but they use bower. Anyway, if what you're looking for exists, it should be in there somewhere.

Is angular-seed the de-facto empty project to start with?

After having been convinced to learn and use Angular.js, I was going to start a concrete web UI application so as to launch the learning wheel of experience. ( The app is going to be some kind of personal planning, to do list, reminder, pomodoro technique oriented, and so on...)
One of the tutorial videos I have seen, by the author of Angular, is about best practices. And one of the best practices is to start with the angular-seed project.
That is what I was going to do, but after googling a little, there are already at least two other projects that claim to be the good starting point:
angular-enterprise-seed
angular-sprout
I'm beginner, but I like to invest in the long term. Should I worry about using something else than angular-seed ? I feel like it's too early to ask myself this question, but if there are already two other projects, maybe there are some good reasons.
I've found that though many people use various seed projects, the easiest & most consistent starting point for an angular app (or any javascript web app) is Yeoman.
This app is a scaffolding tool that allows you to specify generators which will build the up the kernel of your application, complete with whatever libraries you desire (via bower) and a working grunt build file (most generators come stock with a build task, server task for live editing, and testing task)
Though an app like this is necessarily opinionated, the scaffolding it produces is still very generic.
example:
mkdir my-app
cd my-app
npm install generator-angular
npm install generator-karma
yo angular
They all have different merits so it depends on what you are looking to do. I wrote angular-enterprise-seed and can speak to its relative merits.
It is server-agnostic. This is important since a core tenet of AngularJS, and one of many things that make it attractive, is that it follows the Client MVC paradigm. This means it is entirely decoupled from any and all server technologies. Many existing seeds tie AngularJS to server technologies, such as angular-sprout (NodeJS) or grilled-feta (Google App Engine/Java). In the case of the aforementioned projects, if NodeJS and/or Java environments aren't already on your system, then you will have to go through several hoops just to see the seed come up. This can be alienating to PHP and Python developers, which results in limiting the project's community.
Up and running in seconds. Because it is server-agnostic, it can be run in any container (heck the filesystem for that matter). Suggested method is running "python -m SimpleHTTPServer" from the root directory -- this comes native on Mac and Linux so there are no additional steps.
Live preview. It's cheap to check on status of the project because a live version is always hosted on github. Because it's server agnostic, this is automatically done by copying master to the gh-pages branch from a cron job.
Rich styling. It includes Twitter Bootstrap and custom/buildable LESS out of the box, along with Angular-UI, Angular-NG, fonts, and a myriad of other tools to provide rich styling and responsiveness capabilities.
Widgets. Like Angular-Seed and Angular-Sprout, Angular-Enterprise-Seed exemplifies "best practice" layout, routing, etc. But it also provides a host of pre-built components that can be taken off the shelf and immediately reused. This is a bit difficult to do as it can require the convergence of several technologies. For example, to create the grid example, I combined angular-ui, angular-ng, angular-js, and jquery styling. There are component examples for modals, pagination, alerts, grids, and more.
Angular-seed is great as an academic exercise if you want to learn how the pieces work, but it will leave you longing for a more substantial jump-off point.
I haven't used angular-sprout so I can't speak to its merits. Maybe there is some room to merge angular-sprout and angular-enterprise-seed?
I recognize that this is an older question, but it seems to have a fair number of views, so it makes sense to recommend what has recently become a very popular alternative to both Yeoman and angular-seed: ng-boilerplate. ng-boilerplate differs from angular-seed in that it's designed from the ground up for large production web apps, and therefore is a better solution than angular-seed in my opinion.
To explain the differences between the Yeoman and ng-boilerplate methods of app kickstarting, I'll quote ngbp's creator, Josh D. Miller:
Yeoman is awesome. But the problem I have with the generators for AngularJS is that they package by layer rather than by feature. If we store all controllers in a "controllers" folder and all services in a "services" folder, etc., and all our tests someplace else entirely, it can be quite challenging to reuse our components.
This is also pretty good discussion by Josh on the Yeoman angular-generator issues forum, that goes more in depth regarding the setup of ng-boilerplate vs. yeoman.
Just to be clear, Yeoman is not a generator. Yeoman is a format/system for making generators. There are several generators made with Yeoman that you can use to generate an AngularJS application. People often mistakenly refer to one or another of them as "the" Yeoman generator. But there are many. Confused yet? Yeoman isn't the only generator making system. Brunch is another one.
To answer your question, here is a very comprehensive side-by-side comparison of many AngularJS generators one can use to start making a web application with AngularJS. Currently, it contains over 200 different aspects of these things. One of them is file organization style. So you can easily see which ones organize the files by feature if that's important to you. It is to me.
There are still several of these left to be added. The two mentioned in this thread are new to me. But this comparison should give you a good idea of the options and how they compare. It's editable too, so if any of you are experts in any of these things, feel free to share what you know.
God only knows why people keep making more and more of these things instead of just helping to improve the existing ones. If you have any guesses, I would love to have that mystery solved.
EDIT: to gain access to the doc I ask that you either complete a questionnaire to share your knowledge of something or lobby the experts to do so.

I like using Yeoman as well. Try these to get a good scaffold:
npm install -g generator-angular # install generator
yo angular # scaffold out a AngularJS project
bower install angular-ui # install a dependency for your project from Bower
grunt test # test your app
grunt server # preview your app
grunt # build the application for deployment
