is it possible to migrate a plain react-app into next-app? - javascript

Is it possible to change/convert a plain react app into next app?
I have a project created with create react app but things have changed and now I want to switch the project into next app
maybe there's a possible way to do that? or should i start over from scratch to build my next app project?
I've been trying to research on how to migrate the project, but didn't found the solutions.

It's difficult to answer this question without seeing the actual project and dependencies you use, but here's a few considerations:
You'll need to convert your current routing solution to the one Next.js uses. Their routing is determined by the file system structure, rather than in code (like react-router). For more information, see their docs: https://nextjs.org/docs/routing/introduction
Ensure all your components and dependencies can render on the server, this may require moving behaviour that uses browser APIs into useEffect hooks (like window or document properties).
Move your hosting and building to something that supports Next.js configurations. There are a few including Vercel, Netlify & AWS.
Also check out their own migration guides that cover how to convert configurations to Next.js: https://nextjs.org/docs/migrating/incremental-adoption
In short, it really depends on what you're currently using and will require manual conversion your code. I hope this was still helpful.

How to run ReactApp created by create-react-app on XAMP using index.php rather than index.html?

I have thoroughly searched the web about creating a website using React as a front end and PHP as a backend for like a week now. I have found many solutions about configuring webpacks and stuffs. But most of them only aim for index.html. So, I decided to create one LARGE react app and used CDNs of React, ReactDOM, and Babel to run it on index.php which is running on XAMPP. The main reason for creating one large app is because I cannot use full functionality of creating components and importing them.
But now, I want to use MDBootstrap, and its React components. But I cannot use them since importing is not available. I have watched tutorials and read articles about webpack and configured it. But all those were for index.html. And lastly, I have also found tutorials using PHP, XAMP(MySQL), and React. However, most of them run on Node server rather than XAMP server.
So I want to create something like
Website
react_app
index.php
where react_app is created by create-react-app or does have a same functionality as it like imports and stuffs. I do know that NPM server runs index.html from /build/, but I do want to run it on XAMP server using index.php.
Here is a link you can follow to do what you are asking for https://medium.com/#MartinMouritzen/how-to-run-php-in-node-js-and-why-you-probably-shouldnt-do-that-fb12abe955b0
and a possible other answer here Execute PHP scripts within Node.js web server
Only thing is, it is not really advisable to do this. It carries a number of security risks. I would advice you learn to seperate concerns and follow the Model-View-Controller (MVC) design attached to React.
You can still have React as your view while PHP is in the back. requests are sent and received through an api call. Check out this simple tutorial on achieving this https://blog.bitsrc.io/how-to-build-a-contact-form-with-react-js-and-php-d5977c17fec0
I hope this helps you with what you need. If it doesn't, let me know. glad to help!

ReactJS vs NodeJS - Why do I need to create both?

I understand that React is frontend, and NodeJS is the backend that allows Javascript code to function outside of a browser. What I don't understand (and this is after following tutorials online on setting up a React project and a NodeJS project) is why I have to create an instance of each.
For example, in my React project, I managed to create a website. But because I needed a backend, I decided to use NodeJS. But I'm doing NodeJS tutorials, and I can create a website using NodeJS too. I'm confused because right now, it's appearing to be that React and NodeJS do the SAME THING.
I have never worked with NodeJS before so I am a bit confused. I was under the impression that I would just use NodeJS to host the backend, but after seeing that I'm literally having to create an entire website with NodeJS, I don't understand how I'm supposed to use React and NodeJS together.
How do the two, React and NodeJS, integrate together to create a fully-functioning web app? I have yet to see something online that clearly breaks down how the two interact.
React is front-end library. It provides great tooling for creatiing user interfaces. And it creates a single page application. Which means when you open a react app. It does not reload and its really fast.
While you could also use nodejs and something like handlebars to create a website. But that website would be rendered on server and then served to the user. But its alot more than that. There are a lot of things that you want to do on the server. Like authentication. You want that part to be secure. So you keep it on the server.
Now the answer to the final part of your question.
For a fully functional app. You would use react to create user interfaces. And nodejs for creating an API which your react app will call.
NodeJS is not just regular javascript, it is a javascript runtime that sits on top of a C++ engine called V8, provided by Google. Node executes outside the browser, whereas React / Vue / Angular / etc are in-browser javascript frameworks.
React is a whole separate animal; it is a framework that renders its own DOM in the browser. It is a javascript engine that is configured to optimize DOM manipulation.
While the development pattern of frontend and backend appear similar, they are doing different things. React is handling component lifecycles, applying dynamic style rules, processing in-browser data, and making API calls. Node is handling requests from the browser, coordinating access to the server's file system, managing network I-O, performing cryptographic evaluation, etc. Because of these different responsibilities, Node makes use of different dependencies (read: node modules) than a frontend framework.
Ultimately, Node and React communicate through HTTP calls (or, less frequently, through a WebSocket or SOAP protocol).
It would behoove you to read about how node works under the hood.
NodeJS is just a runtime that allows you to run javascript code outside of the browser.
In order to compile and transpile the react JS app, they use webpack and other tools which runs over NodeJS.
NodeJS will serve as your backend, whereas ReactJS will create the interface/UI where you can actually manipulate your server (nodeJS). So first you'll write your NodeJS server or API. You don't need to use ReactJS to create a frontend that would interact with your node server, like you said you can use NodeJS to create your views as well through a different library. ReactJS is just one choice of many for the front end of your NodeJS app.
The point is that react and any other SPA library is working on a client-side (browser).
React fetch and consume the data from the server API.
You don't need to use Node.js for building API. You can use various frameworks based on the technology you prefer.
If you are not familiar with the Back End, you can use https://www.npmjs.com/package/http-server to have a fake API service and can build the Front End part with it.
NodeJS is a javascript framework that allows you to create a server to serve up websites using Express or the built in libraries. It also is capable of building a website with just NodeJS.
You can take advantage of the ability to do server side rendering with a NodeJS server.
https://reactjs.org/docs/react-dom-server.html
There is a ReactJS framework called NextJS tha has server side rendering of ReactJS component.
https://nextjs.org/#features
You could potentially have some areas of your website that are built solely with NodeJS and other pages that use ReactJS and a NodeJS backend. But it is cleaner to use ReactJS for the front-end and NodeJS for the backend.

Change built react project

I have deleted a react project but have it’s built version on a server. Is there a way to reverse the build process? I’ve read that doing changes to an already build project is nearly impossible. Any help? (It’s is gatsby-react Template I’ve used but with major changes to design etc.)

Ionic3 import external web hosted javascript library

I am trying to create a iOS/Android app based on a client side html5 web project, (i.e. a site) I did.
I thought Ionic would be the ideal choice, that it would help me to port my web application as soon as possible.
In my site, I would use the 'script src="https:// ..."' tag to load the external lib, then calling it in another script
tag. However, I can't import and use it in Ionic3.
I tried many solutions tagged with 'ionic2' and nothing really seems to work.
It also seems no one knows a general solution for this, since each answer was case-specific.
Does anyone know a general way of importing external js file and using its objects and 'classes' in ionic3?
(I would prefer to load from the web, but I am also accepting to download and load it fro file. )
(If ionic isn't the best way of accomplishing my objective, I am open to suggestions)
I think you need to wait till release the Ionic 4 and Stencil.
What is all about Ionic 4 and Stencil?
The magical, reusable web component generator.
Stencil is a tool for building modern Web Components
Stencil combines some of the best features from traditional
frameworks, but outputs 100% standards-compliant Custom Elements, part
of the Web Component spec.
Stencil was created by the Ionic Framework team to build faster, more
powerful mobile and web apps. Stencil is the foundation for the next
generation of Ionic Framework, but is completely independent of Ionic
or any other UI framework.
Here you can see the official doc.
Nice video about the power of Ionic 4
Nice article about it
First of all have a look at this useful ionic resource, it explains how to add thirs party libraries using npm.
If you cannot use npm because of whatever reason you have to put the source .js file into your assets/js folder and import it in your index.html using a <script> tag. Then you have to tell typescript that your library exists. This is done like so: declar var <library-handle>. Where <library-handle> can be an exported function/class if the library already uses ES2015 or the object which exposes the functions using prototype. This is the tricky part where you may have to try a few things until you get it to work.
You can have a look at my answers here, here and here where I explained how to add different third party libraries to ionic projects.

How do I use an ember component in more than one ember application?

I have two different ember applications, but a specific subsection of both will be absolutely identical. I would much prefer, moving forward, to edit a single source of truth for this functionality, and then plug it into both applications whenever it is changed.
What would be a way to accomplish this?
I would assume there is a way to simply plug in the components themselves or, barring that, building another ember app and embedding it in the larger app. Either solution, or another solution, would be acceptable.
Your question is about building and distributing applications, rather than about Ember per se. I would first define the shared code in a namespace: (http://emberjs.com/api/classes/Ember.Namespace.html) and then wrap that up as a node.js module, with a package.json file that describes the module.
Then, I would use bower to install the package by specifying the module in the bower.json dependency section. (http://bower.io/)
This approach gives you more control over your development of all three products- two applications and a shared framework. It then allows you to version your shared code so you don't have to upgrade both applications at the same time- Quite a few problems solved by leveraging the package management features of bower.
One way to achieve this, which actually has much less to do with ember itself, is to have a common place to retrieve files for you applications. Such as a CDN url that you can hit for common libraries, images, global files etc. It seems as thought you may be trying to have the same file locally in two places, and have both update whenever you make changes to one common place. This could also be achieved by simply having a symlink to that file in each project.
Either way, your solution will probably be a server action than it will be an actually Ember issue.
Hope this helps.
