In our code, if we were sending an HTTP request to: We would just need to change it to: This means that we would be able to access this server through: In this example, we are assuming that the server is running over port 3000 but this might be different for your circumstances. Our local backend/server is also running at this same address, just on a different port. Which means that the Ionic application us running over port 8100 at the IP Address 192.168.0.105. We can use this address instead of localhost and it will allow us to access a server running on our computer from the Ionic application running on a device. What is important for us is the External address listed above. This is where the live development servers are running and where we can view the application. When you run this command, you should see a message like this pop up at some point: Development server running! Local: External: Use Ctrl+C to quit this process It is also possible to do this without Ionic and the Ionic CLI, see the documentation on live reload for more information. NOTE: This tutorial assumes you already understand the basics of using Capacitor with Ionic applications. Then just run the following command to get your application ready to run on iOS or Android: ionic cap run android -l -external In order to do this, you will need to install the native-run package globally if you have not already: npm install -g native-run As long as you are running your application on the same WiFi network, you will be able to access a server that is running on your computer from your external device. So, how do we forward these requests from our mobile device to the computer that is running the server/backend? Using the Ionic CLI to access localhost externallyįortunately, this is quite easy to do with the Ionic CLI and Capacitor. Let's say you've got a server running on your machine at This is fine when you are testing your Ionic application on your computer because you can just send your HTTP requests to: But once you deploy the application as a native iOS or Android application to your device, this URL will no longer work since the context for localhost means that it will no longer be referring to the computer where your server is running. Using the Ionic CLI to access localhost externally On the left we have the terminal and on the right, we have our actual device’s screen casting through Vysor.How do you access localhost from a mobile device? Now you have your app running on a physical device with native plugin support and live reload. This should bring up the app inside the DevApp running on your device. Make sure your mobile device and your computer are on the same WiFi network. If you do not have the latest version of the Ionic CLI installed, run the command below: npm install -g ionicĭownload the Ionic DevApp ( iOS/ Android) on your device(s). You can see all code changes immediately on any device running DevApp. As soon as you run ionic serve, DevApp identifies and loads your apps, so you can preview them in the app. Find your apps running on local network.And you don’t need to install Android Studio or Xcode to view your apps on devices. This removes the need to set up Android SDK. They’re super easy to debug as you change your code because all it takes is running ionic serve. You may have an app that depends on some of the native plugins. The following features make Ionic DevApp great for developing Ionic apps: What’s awesome is that it is free and available for iOS and Android. When you run ionic serve, it installs the application onto all the devices running the Ionic DevApp. This makes it easier to test native plugins and any applications you are developing. It comes with tons of pre-installed native plugins ( view plugin support here). Ionic DevApp is an app that runs on your iOS/Android device. Luckily, Ionic announced the Ionic DevApp on 31st Oct 2017. But it usually took hours to set up the environment and tools to run/debug on devices. In general, hybrid apps with Ionic have always been fast. Tablets and Progressive Web Apps (PWA) come next in being the most targeted platforms. In Part 2 we’ll talk about the Ionic DevApp to see how it helps in developing apps faster.Īccording to a survey by Ionic, 94.3% of developers are targeting Android while 83.2% of them targeted iOS. In Part 1 of this series, we created a rapid prototype using Ionic Creator.
