React APP ReferenceError: require is not defined - reactjs

Integrating GULP with my React Project. On firing up the project, the following is the error that I face: https://prnt.sc/trw1if
Do check the screenshot above. This is a particular issue that I face.
Do let me know what am I doing wrong here. I've tried different presets for it as well. I am also attaching my GULP file here:

var sass = require('gulp-sass');
const imagemin = require('gulp-imagemin');
var concat = require('gulp-concat');
var uglify = require("gulp-uglify");
var browserSync = require("browser-sync").create();
const rollup = require('gulp-better-rollup');
// const babel = require('rollup-plugin-babel');
const resolve = require('rollup-plugin-node-resolve');
const commonjs = require('rollup-plugin-commonjs');
gulp.task('jsCompile', function () {
return gulp.src(['src/*.js', 'src/**/*.js', 'src/**/**/*.js'])
.pipe(babel({
presets: ['#babel/preset-react', '#babel/preset-env']

.on('error', function (err) {

console.log('error Babel: ' + err.message + '\n');
console.log(err.codeFrame);
this.emit('end');
}))
// .pipe(rollup({ plugins: [babel(), resolve(), commonjs()] }, 'umd'))

How to eliminate dead code elimination in React using only Gulp and Browserify?

I try to build my React project with gulpfile.js in production mode so the query developer tools show green color in browser tab. However, it still failed with dead code elimination error, which means development version is still detected in react developer tools.
I have already tried many ways to eliminate this error. One of the closest solution is to add 'unreachable-branch-transform' and gulpif argv in browserify part in gulpfile.js. Please check gulpfile.js content below.

My React project is only using gulp and browserify inside gulpfile.js, so this project doesn't use any build tools listed in documentation link below (grunt, webpack, browserify (standalone),rollup).
https://reactjs.org/docs/optimizing-performance.html
Do you have any suggestion how to eliminate dead code elimination, but only by using gulp and browserify inside it ? Thanks in advance.

Requried is not defined, after migrating from Gulp 3 to 4

I have a project which used Gulp 3 + Node 11 (The project is AngularJS with the basic webpack + babel etc ...).
The need arose to migrate to Gulp 4 + Node 12. I changed the syntax from Gulp 3 to 4, the command "gulp build" is running, the console appears that everything is ok.
But when I try to access the application it says that:
Uncaught ReferenceError: require is not defined
at eval (eval at globalEval (jquery.js:2)
This error is repeated with other libs as well.
Below a part of my gulp.js, the calls part, probably the error is here. I think I'm getting complicated in this business of having to force sync on gulp 4, which I didn't have on Gulp 3.

I just run into the same problem while upgrading to gulp 4.
The depending tasks have to be specified as series or in parallel, just the name is not enough anymore.
Example
gulp.task('copy', ['sass-min'], function() {
Becomes
gulp.task('copy', gulp.series('sass-min'), function() {
gulp.parallel can also be used to execute the tasks in parallel
I had this exact problem with Gulp and it turns out that you must do away with tasks like that.
You must define your tasks as simple functions and then use your functions to define a task with gulp.series() or gulp.parallel().
I don't use this on Angular, but here's my gulpfile:
const bsync = require('browser-sync');
const gulp = require('gulp');
const autoprefixer = require('gulp-autoprefixer');
const sass = require('gulp-sass');
function sync(done) {
bsync.init({
files: [
'*.html',
'assets/css/**/*.css',
'assets/js/**/*.js'
],
host: '0.0.0.0',
server: './',
port: 8080,
reloadDelay: 1000,
ghostMode: false,
notify: false
});
done();
}
function styles() {
return gulp.src('./assets/scss/**/*.scss')
.pipe(sass({ outputStyle: 'expanded' }).on('error', sass.logError))
.pipe(autoprefixer({ remove: false }))
.pipe(gulp.dest('./assets/css'))
.pipe(bsync.stream());
}
function watchFiles() {
gulp.watch('./assets/scss/**/*.scss', styles);
}
gulp.task('start', gulp.series(sync, styles, watchFiles));
I've got inspired by this example. Hope it helps.

setting proxy or backend URL while doing gulp build:dist

We have some code in Angular JS which is build using gulp (babel).
We have necessity to redirect the api service calls to a different server.
Hence, which development we run gulp server and with that add the api-host server in the proxy argument while running gulp server, as follows:
gulp serve:dist --mock no --proxy http://<host-name>:8090
Now, after development, we build and distribute the same bundle to different host (not the same host where the api services are hosted). Now we are not able to connect to the api server. The command we use to build is
gulp build:dist --mock no
Even if we add the proxy argument here, it doesn't works.
gulp build:dist --mock no --proxy http://<host-name>:8090
We tried customizing the "gulpfile.babel.js" file. but no result.
The following is the "gulpfile.babel.js" used:

You can use gulp-ng-config to add constant in you app module.
Or you a JSON as a config file inside your gulp:
//Gulp file
var fs = require('fs');
var settings = JSON.parse(fs.readFileSync('./config/config.json', 'utf8'));
....
gulp.task('statics', g.serve({
port: settings.frontend.ports.development,
...
}));
gulp.task('production', g.serve({
port: settings.frontend.ports.production,
root: ['./dist'],
...
}));
