Web applications with javascript : <p>Now I program all my web apps with Flask or Django. (blogs, social networks...). I need templates, db access, controllers, routing...</p>

<p>Now I want to do same web applications, but with javascript.</p>

<p>People tell me : You need NodeJs for server-side, Angular for the front, and for example firebase or mongodb. Or also you can use Express JS.</p>

<p>But can I just use Angular JS and Firebase for start a big web app ? Need I Node if Angular can Access/Update/Delete in my db ? </p>
