Write React component and deploy it at runtime? - reactjs

I'm a bit new to React.
My company is starting to build a product than needs to be customized by any client.
Is it possible to create a component (let's call it plugin) and deploy it into a folder in a production environment and that component being rendered without recompiling the entire app?
e.g.: I have a form and i need another form calling a client's API that renders some info and then pass that info to the main app form. That 2nd form should be this kind of plugin, due to the fact that it depends on the clients' APIs for the component to render a table, a chart, or whatever the component itself renders.
I've been googling and i haven't found a solution yet.
Thank you all :D

Find best practice to make dynamic layout React app in server

Definition of our requested Dynamic App
We Have to make an app with Dynamic Layout.
Our marketing team needs to change layout of page. for example ordering the components or maybe add new route to react app or maybe add or remove some component from some page.
Technologies that we are using
We are using typescript as our base language of create-react-app and redux for state management.
My Solution
My Solution for this is to generate .TSX file in server on changes come from a panel and build entire project with new files created by server.
I prefer to not use dynamic import, because user must waits for a api to get the page layout structure then client must import the components and after that every component request it's desired api call from server! Too much time waist!!
Your Idea
What do you think about this structure?
Is there any bottle neck that I may encounter? or maybe i didn't saw?

What's the difference between React App and React Component

We will be doing our first project using React.
It will not be a Single Page App, but a Multiple Page App.
What I'm trying to figure out at the moment is : what's the difference between a component and an app.
If I only use components, can I still use Redux to have some state management on the current page ? Or do I need an app for this ?
Thanks for the information you can bring !

There is no special object called "React App". React Components build an "React App" by coming together.
But React Components are formed like tree structure. That means each component have a parent component so you can create a React Component that named "App" and can put another components inside it.
You don't need redux for state management in React Components.
I hope the answers have helped.
Your app may contains a single component and still it will be a react App. If you are using multiple components in a page you can still use react-redux. Redux is basically a container for your states and let suppose you need some state from one component to be consumed in another, Redux provide you a mechanism to make the communication efficient and predictable.
You can also look at the React Context APIs as an alternate to Redux.
An app is simply a component that holds the root of the work you are trying to do. For example an App may have the navigation menu, testimonials, adverts, content, login avitar etc.
If you are making a single App per page (For example a testimonial) then you would still have a SPA. For example, adding testimonials, searching, editing.
You should only use Redux if you are using a SPA with lots of different parts with data in common. If you are making a one-app-per-page and there is no cross over in data then you can simply using Reacts State/Props to hold your data.
Redux is good, but it forces you into a complex path your should try to avoid. If you find yourself wanting data from different domains (customers address and a list of testimonials) then you should use Redux.
If this is a new applications (green) then I strongly recommend you build the whole thing within a SPA using React-Router to control components. you can use frameworks like Next.JS to ensure the site remains small in size (dynamically loading script only when required).

Set an externally accessible URL for a React component

I developed a React component representing a window that allows the user to interact with a chatbot. This window opens when the user clicks a button. Now, I want to make this button available in any site or application of my choice. The first idea that came to mind is to associate a URL to this button so I can call it in our site or application by simply creating a link like:
Chat with the robot .
I find the idea functional but I do not know how to associate a URL to a component in React. I looked at the React-Router side of what I understood it just allows to create the navigation between component of the same application but I do not know if its URL can be accessible outside the application where they are created.
Do you know any tips for solving such problems?
And if you have ideas other than linking the URL to the component, I'm interested.
Thank you in advance !!!
You cannot use a react component by pulling it in as external code. react-router works by wrapping you application. Any component you want to use has to be part of the actual codebase.

What happens with the state in a React isomorphic App

I am building an isomorphic app with React that must support users without JS.
I am new in this technology and I have a basic doubt:
The server can store the components states to emulate what React does in the client-side?
I imagine this flow when the user dont have JS:
The user click a button and send a request to the server.
The server recovers the state of the app and makes changes in it.
The components listen this changes and are rendered again.
Is it correct?
Assuming that you're using react-router :
The server aims to initialize your state, to provide it the default minimum values necessary to make your application work while getting an url.
For example, if you have an application in which you want to display a user list, let say on /users URL, when you'll send your first request, the server will store the users in the react state.
After that first load, you'll be working on the client side using react-router, and making XHR request.
However, if you refresh your page, the process will start again : first load initializing the state and then client side navigation.
EDIT : Explanations =>
When you want to use react on the server, this means that you use a Nodejs server. The fact is that react-dom provides a method called renderToString that transform a react jsx component into standard HTML.
This aims to load the first call faster
Why ?
When you load a "big" JS application on the client, you have some delay time, the time your browser needs to download your JS bundle.
Server side rendering aims to avoid that behaviour, or at least, to gives the feeling that the app starts faster.
In no case you can only use react, even if you use your server side renders. Why ? . Because your events on buttons, or asynchronous load on client, or keypress are in JS language.

How to add universal support existing react project

I've created a react redux project, now how do I add some SEO functionalities to project? I do not want to waste much time while refactoring codes.
You need to setup the redux store on the server and pass its initial state down to the client, so that the server-render and initial client render don't differ
Not all life cycle functions are called on the serverside, mainly componentDidMount is not called. This indeed helps if you want to do some AJAX data fetching (which you only want to do on the client).
If you are using react-router you need to setup the serverside route matching
Here are some more details: React can be used on server side rendering. What does that mean?
