Disable chrome react DevTools for production

Question

I'm trying to browserify my react app for production using gulp and envify to setup NODE_ENV. So I can remove react warning, error reporting in the console, and even my code to disable some features like the require of react-addons-perf.

And it's working great. When I search in my app.js for "production" to see if there are theses typical conditions :

if("development" !== "production") {
    ...
}

There is nothing, so, as I said, it seems to work well.

But, I still can see that chrome's react DevTools tab with all react components, like if I was on a development website. How can I disable this tab in chrome's dev tools ?

Here is my gulp task :

var production  = process.env.NODE_ENV === 'production' ? true : false;
var environment = process.env.NODE_ENV ? process.env.NODE_ENV : 'dev';

...

var bundler = browserify({
    debug: !production,

    // These options are just for Watchify
    cache: {}, packageCache: {}, fullPaths: true
})
.require(require.resolve('./dev/client/main.js'), { entry: true })
.transform(envify({global: true, _: 'purge', NODE_ENV: environment}), {global: true})
.transform(babelify)
.transform(reactify);

var start = Date.now();
bundler.bundle()
    .on('error', function (err) {
        console.log(err.toString());
        this.emit("end");
    })
    .pipe(source('main.js'))
    .pipe(gulpif(options.uglify, streamify(uglify())))
    .pipe(gulpif(!options.debug, streamify(stripDebug())))
    .pipe(gulp.dest(options.dest))
    .pipe(notify(function () {
        console.log('Built in ' + (Date.now() - start) + 'ms');
    }));
};

According to an issue on Github, you can add run a single javascript line before react is loaded to prevent it.

From #191 of react-devtools

<script>
window.__REACT_DEVTOOLS_GLOBAL_HOOK__.inject = function () {}
</script>

Then, you may consider wrapping this with your environment condition, like that you could do sth like below in your server side rendering. Let's say Pug (formerly known as Jade):

#{process.env.NODE_ENV == 'production' ? "window.__REACT_DEVTOOLS_GLOBAL_HOOK__.inject = function(){}" : ""}

However, it would be still a good practice to put the business logic and the sensitive data back to your server.

If you are using redux-devtools-extension you can do this.

const devTools =
  process.env.NODE_ENV === "production"
    ? applyMiddleware(...middlewares)
    : composeWithDevTools(applyMiddleware(...middlewares));

const store = createStore(rootReducer, initialState, devTools);

This will make sure your devtools extension only works in the development environment and not in the production environment
