Stop watching folder changes in reactjs - reactjs

Question

i'm working on a react project where user can uploads files,and the problem that i'am facing is when i upload a file to the server and save that file into folder called uploads which lives in the public folder,then when this process finished the page refreshed that's because the app watching for any changes and refresh the page
and i know that i can stop this by edit the webpackdevserver.config File but i don't know how to do that.
webpackdevserver.config:

const ignoredFiles = require('react-dev-utils/ignoredFiles');
const redirectServedPath = require('react-dev-utils/redirectServedPathMiddleware');
const paths = require('./paths');
const getHttpsConfig = require('./getHttpsConfig');
const host = process.env.HOST || '0.0.0.0';
const sockHost = process.env.WDS_SOCKET_HOST;
const sockPath = process.env.WDS_SOCKET_PATH; // default: '/sockjs-node'
const sockPort = process.env.WDS_SOCKET_PORT;
module.exports = function(proxy, allowedHost) {
return {
// WebpackDevServer 2.4.3 introduced a security fix that prevents remote

// While we're investigating better solutions, for now we will take a
// compromise. Since our WDS configuration only serves files in the `public`
// folder we won't consider accessing them a vulnerability. However, if you
// use the `proxy` feature, it gets more dangerous because it can expose
// remote code execution vulnerabilities in backends like Django and Rails.
// So we will disable the host check normally, but enable it if you have
// specified the `proxy` setting. Finally, we let you override it if you
// really know what you're doing with a special environment variable.
disableHostCheck:

// project directory is dangerous because we may expose sensitive files.
// Instead, we establish a convention that only files in `public` directory
// get served. Our build script will copy `public` into the `build` folder.
// In `index.html`, you can get URL of `public` folder with %PUBLIC_URL%:
// <link rel="icon" href="%PUBLIC_URL%/favicon.ico">
// In JavaScript code, you can access it with `process.env.PUBLIC_URL`.
// Note that we only recommend to use `public` folder as an escape hatch
// for files like `favicon.ico`, `manifest.json`, and libraries that are
// for some reason broken when imported through webpack. If you just want to
// use an image, put it in `src` and `import` it from JavaScript instead.

after(app) {

app.use(redirectServedPath(paths.publicUrlOrPath));
// This service worker file is effectively a 'no-op' that will reset any

app.use(noopServiceWorkerMiddleware(paths.publicUrlOrPath));
},

};
and here where is store the files uploaded:
structureAPP
So my question is Like so:
How do i can edit webpackdevserver.config File to stop watching uploads File ?
i have been searching for this problem for two days and didn't fix it.
thanks in advance.

watchOptions: {
ignored: ignoredFiles(paths.appSrc),
},
This is indeed where ignored path are listed but ignoredFiles(paths.appSrc) is not the src folder. If you look higher you see ignoredFiles.js comes from the react-dev-utils module.
const ignoredFiles = require('react-dev-utils/ignoredFiles');
With react create app, the default ignoredFiles.js returns the node_modules folder which speeds up things by avoiding the watcher to go through all modules. Now it is possible to add more folders as watchOptions.ignored accepts an array So you can add your uploads path directly in the watchOptions.
watchOptions: {
ignored: [ignoredFiles(paths.appSrc), yourUploadPath],
},
