It's just going to patch the code that was changed and keep the state in your app. ![]() Hot Reloading is not gonna reload your entire application. It's just gonna be like, okay, the file changed, reload the entire app. ![]() The difference between the two is, Live Reloading is gonna reload your entire application. It's different than the next thing, which is Hot Reloading. Enable Live Reload, that's just going to watch your files and then reload the app for you when things change. ![]() Debug JS Remotely, we're gonna do that in just a second, it's pretty cool. It's gonna reload your app, completely reinitialize the state and reload your app. On this developer menu, the first thing we have is Reload, which does exactly what it sounds like. So let's just walk through some of the stuff that's happening. The main thing is, on your emulator, on your device or whatever, as long as you can hit the menu button or shake your device, you get access to the developer menu here. > Scott: DevTools, we kinda saw a lot of the stuff that I was going over. Now these pages will refresh on file changes either in your tests or application files… blazingly fast!Ĭodementor React Expert Christian Alfoni is a full stack web application enthusiast currently working on JSFridge, which brings video and fiddles into a new concept, jFlux.io, a unidirectional framework that gives the functionality of React JS components in a much simpler syntax, and more.Transcript from the "React Native Developer Tools" Lesson When on you app and/or your tests, hit that button and you will see the little circle in the center will become a black dot. This puts a small button up in the right corner of your browser. To make LiveReload work you need to install an extension to Chrome, LiveReload. Go to “localhost:3000/testrunner.html”, here you will find your tests.Go to “localhost:3000”, here you will find your app.Start up a webservice in the “build” folder, f.ex.Think: "require('react')" or "require('underscore')" var dependencies = // Now this task both runs your workflow and deploys the code, // so you will see "velopment" being used to differenciate // what to do var browserifyTask = function ( options ) ) Getting in the flow These are NPM modules you have // installed in node_modules. We need a bunch of dependencies, but they all do an important // part of this workflow var gulp = require ( 'gulp' ) var source = require ( 'vinyl-source-stream' ) var browserify = require ( 'browserify' ) var watchify = require ( 'watchify' ) var reactify = require ( 'reactify' ) var gulpif = require ( 'gulp-if' ) var uglify = require ( 'gulp-uglify' ) var streamify = require ( 'gulp-streamify' ) var notify = require ( 'gulp-notify' ) var concat = require ( 'gulp-concat' ) var cssmin = require ( 'gulp-cssmin' ) var gutil = require ( 'gulp-util' ) var shell = require ( 'gulp-shell' ) var glob = require ( 'glob' ) var livereload = require ( 'gulp-livereload' ) var jasminePhantomJs = require ( 'gulp-jasmine2-phantomjs' ) // We create an array of dependencies. By letting our current workflow bundle our tests with external dependencies and watchify we can make this a lot faster! It would also be nice that our tests run automatically when we do changes to our project. Now Karma is great, but by including browserify as part of the testing it got very slow. The initial version of this workflow used Karma for testing. You will not do any changes to React JS or underscore I suppose? Testing What we want to do is only touch these external dependencies once and never touch them again during the workflow session. You might not notice this when only React JS is part of the bundle, but as you load up more dependencies it can take several seconds on each save and rebundle of your project. Luckily we have watchify that makes sure that it does not rebundle what it already has bundled, BUT browserify still goes through the files and figures out if something should be done. When browserify rebundles your project it goes through all the require statements in your application code and figures out what to put into your bundle. You can grab this boilerplate at react-app-boilerplate.There were specifically two things we did not handle very well on the initial workflow: Well, I got some more experience with it and here is PART2. I wrote an article on working with React JS in a browserify workflow.
