I'm building a web app with the frontend done in react, and I was wondering if it's possible to compile my react code into static HTML and JS files to be used with any server. So far I've been using the server run with
npm start
but for my final project I need to use a different one.
npm run build
This command creates a built version of your application in the build folder
Static builds are a standard in react deploying pipelines. You have to setup a build pipeline with webpack configuring it for minification assets management and so on.

I have created two apps using 'Visual Studio Code' and 'node.js.' I run them using command 'npm start,' and they show in the browser. I want to build them or deploy them so they can be used by anyone. It says there to use command 'npm run build.' How to do that, and what technique you use in order to build them?
It depends on what configuration you used for building the React app. If you used create-react-app, npm run build is the correct command for building it.
If you used a different configuration (e.g. webpack), you should use the relevant command for that configuration.
Either way, deploying it will be as easy as copy/pasting the build folder's content to the server you want to host it, after running the build command.
Visual Studio Code or any other Code Editor for that matter is not relevant. You can develop, build and deploy any React app using any Code Editor you want, it's just a matter of preference.
"Building" refers to the task of preparing (transforming, minifying, compressing, etc.) all the relevant project files so that they're ready for production (assuming that your build scripts are configured to do so).
"Deploying" an app is usually a separate task that will deploy (upload) your current project build to a development platform provider like Firebase, Netlify, Azure, etc. Note that you have to register with a provider and setup a new project on their end before your deploy your project.
Which provider you use is totally up to you. Also, you have to configure your current project once you've chosen your development provider. They'll provide instructions on how to deploy your project.
On a side note, keep in mind that you can configure your own npm scripts so that they run whatever you want. More about that here
kindly we need to build my created app with static bundle how I can do it with the react-react-app template.
Best Regards
According to this it will be sufficient to run
npm run build
if you've created your react app using create-react-app.
I have not checked it.
A second way would be to use webpack as a third party tool.
Typically deployment process: You build once
In Java or any other programming language, you build your application once and then deploy to various environments. There is like .env or .properties file which has environment configurations that are loaded when application starts.
How does react work
In react, from my understand there is package.json. So, it uses it to do build. OUr package.json has following content:
"price": "http://11.222.111.122/myApi/pricing",
"teacher" : "http://11.222.111.122/myApi/teacher",
"mainbanner" : "https://11.222.111.122/myApi/mainbanner",
We running build the application and run on Apache server (not on node.js)
Question:
a. How can we have environment file so that we can specify to use above urls at time of starting application.
Obviously, we have different urls for different environment.
Navigate into your React project folder using Terminal or CMD and build your React project using command:
npm run build
Then a build folder will be created inside your React project which will contain the final production files. Just upload those files into www or public folder of your Apache server.
If you want use it as subdomain, upload it to your subdomain folder.
Remember that React built version works like other Javascript web applications at the end.
I am developing a project with frontend on ReactJS and backend on Java (Spark framework). To build server with frontend, I build the frontend using yarn build and then, using Maven, copy contents of build folder to src/main/resourses/public folder, from which Spark serves all static files. Recently, I moved to CRA and since then all icons disappeared on production build.
When I run the project on webpack-dev-server, everything works fine. All icons are loaded as you can see below:
But when I build production version of the frontend and copy it to the public folder, I get an this error:
The same fragment on production build:
My thoughts are that either icon fonts are copied incorrectly at some point, or the server cannot properly load the fonts, which is less probable as they were loaded earlier when I did not use CRA.
Also, it seems that fonts do exist in the website, because they appear as Sources in Chrome Dev Tools. However, as I said they might be loaded improperly.
P.S. I'm using the following versions of Semantic UI. I generated semantic folder in src directory using npm i semantic-ui.
semantic-ui: ^2.4.2;
semantic-ui-react: ^0.85.0
I found an issue. The problem was that after I built the frontend, Maven incorrectly copied the production build to the public folder
The solution was found here
I come from a background in Angular, but I wanted to start learning React. I want to make a React front-end for a nodejs Express web service.
In Angular, I could simply build the source code into a static folder with a standard index.html, and it can be deployed on any web server. With React however, every tutorial I see is about running React in its own server using create-react-app and npm start.
I know you can also just use script tags to import the React framework in a static page, but then you can't use JSX syntax, and I would like to. Is it possible to simply build a React project into a static folder with an index.html that can be deployed on any web server?
Yep, you can do what you're describing. If you want to use JSX syntax, you'll need Babel, which transpiles it into standard JavaScript.
You can avoid the complexities of setting it up by using create-react-app to create the app, then running npm build instead of npm start. This will compile everything into a build directory, complete with index.html.
CRA uses its server for development purposes. You don't need CRA for using React of course. But, as your app getting bigger and bigger you will need some more extra tools. For example you want to see your code instantly without refreshing your browser. Here comes the dev server and hot reloading.
CRA uses Webpack behind the scenes. It is a great tool for bundling (obviously) all your files (including css), minifying, uglifying, optimizing your code etc.
For simple code or testing purposes using one file and attaching React and Babel to your file could be enough but for real apps you will need more. Either you will use something like Webpack on your own or you will use CRA and let it do all the extra stuff for you.
