The new feature is dead simple all you need is a Codepen URL, and you’re good to go. Thankfully, those days are gone! Now, you have the ability to start a project based on a Codepen demo. You’d start a new project, copy all the assets from Codepen into their appropriate locations, remove the inline template, go back and make sure you caught that lone semicolon you forgot the first time… Until now, taking Codepen demos and moving them into an Ionic project was a bit of a mess. It also provides an ideal environment in which to demonstrate issues that you may find during your development. It’s the perfect place to share code and play with ideas and concepts in a sandbox. Ionic loves Codepen! In fact, we really love Codepen just check out our Codepen page. Ionic App LiveReload Command Examples: $ ionic emulate ios -livereload -consolelogs -serverlogs Live Reload app dev files from the device How do you start it? You can pass a few flags, in any combination, in your run/emulate commands: $ ionic This lets you build your app quickly in the browser, then debug it on an actual device or emulator ( Genymotion works, too). Not only can you run LiveReload, you can also access console logs from the device and server logs showing which files the device is requesting. Do note, however, that LiveReload only works for devices that support web sockets. This reduces the requirement to constantly rebuild the app for small changes. With this in mind, we added the ability to have LiveReload run when you’re testing on a device! The LiveReload functionality is similar to Ionic Serve, but instead of developing and debugging an app using a standard browser, the compiled hybrid app itself is watching for any changes to its files and reloading the app when needed. This allows you to develop your app in the browser and have it update instantly when changes are made to any development files. One of the best features of the CLI is the LiveReload server that gets started when you run ionic serve.

When I have to only modify a few lines of HTML, CSS or JavaScript/TypeScript which I certainly know won’t break anything which needs debugging.When I know that there is close to no chance of any JS error which is very hard to debug.When I don’t have to develop anything, only to run/serve the application.Well, this is totally up to you when can you turn this off, but for me, these are the cases or scenarios when I turn off the source map: The side effects of disabling the source maps are just the matter of our understanding □ When are the cases where you don’t need source maps? Which can be easily seen in the transpiled code without the need of source map. For example, the exception clearly says that at line 2729, some variable is having null value and you are trying to invoke items on it. Transpiled JavaScript code in Chrome’s developers’ consoleĪs you can see, it is not very hard to debug simple problems even the source map are disabled. Since this article is about source maps in development, let’s see what happens when we run our Angular app using ng serve: For example, fast page load time with small-sized files. While in production, on the other hand, our primary focus is performance. While in development, Angular by default enables the source map since our focus is development □, of course, so our code tends to fail and we often need to inspect our code in browser’s development console. Let’s talk about source map in Angular/Ionic application. source maps - a short introductionĪ source map is a general concept used by browsers which help you debugging your code easily by reconstructing the original source (from compiled/minified) and present the reconstructed code in the debugging or developers console. So that your debugging in the browser can be simplified. Hmmm… in simple words, source maps are files which map from the transformed (compiled or JavaScript) sources/files to your original source code. Well, one of the reasons this happens is when you are using various libraries along with some big fat library (like Angular Material) and the source maps are being generated and used. Have you ever felt that whenever you run some of your Angular/ Ionic application ( ng serve or ionic serve) your system’s fan gets superpower (basically starts running & sounding with full power due to low memory)?
