1. How Do The Top Mobile
App Companies Debug
Ionic Applications?

2. Introduction
It doesn’t take long for a few problems to start popping up when working with Ionic applications. That’s why
the best developers share their understanding of Ionic app debugging here.
Debugging an app created using Ionic isn’t always easy. After all, every digital product behaves differently on
the browser. The same goes when the top mobile app companies launch it as a native application.
However, these things don’t stop the top mobile app companies from debugging applications created using
Ionic. The experts working with such establishments are proficient in various tools designed for debugging.
They also understand the techniques they must apply at the right spot confidently to fix a problem in the code.
This topic will attempt to elucidate how the top mobile app companies debug apps created on Ionic. It’ll also
contain information on API call inspection and the methods of accessing the underlying database.
Furthermore, you’ll learn a bit more about exploring stored application files.

3. Debugging tools for the browser
Before entering the thick of it, you should check out the basics first. As most of the top mobile app companies
design Ionic apps like websites, the debugging process matches the methods employed in fixing regular sites.
Most developers prefer to use Google Chrome, but it’s also possible to do it using Safari, Firefox or any other
recognized browser.
The top mobile app companies press a combination of three buttons to toggle the tools required by developers
on Windows and macOS devices. The button combos are, of course, different for both. The only thing you need
to know is that this area is where the top mobile app companies do their magic.
These options don’t just help developers see console messages but also allow them to perform every
debugging task, whether it involves inspecting memory usage or setting breakpoints.

4. Debugging iOS applications remotely
It doesn’t matter whether the top mobile app companies deploy an app to a native gadget. It won’t change the
fact that it’s a web application. Naturally, the developers will be able to keep using browser-based tools for
debugging.
It’s a procedure experts describe as remote debugging. At any moment, the top mobile app companies retain
accessibility to every native device log that happens inside their applications.
The name comes from the need to connect to the browser app-fixing tools to a remote webview. The top
mobile app companies wish to start with iOS applications first. The developers will begin by deploying the app
to the connected device or a simulator. They can even do it with livereload when using a capacitor.
The fun starts from here when they open Safari as it doesn’t work with Chrome for iOS. First, the top mobile
app development companies will enable the “Show Develop” menu in the menu bar within Safari. Then, they’ll
select the “develop” menu from the top because they have the device and the running webview inside the
same.
It’ll lead to a new window with every known debugging tool devised for browsers. In this window, the top
mobile app development companies will now debug the Ionic app development as it runs. The process will be
like performing the task on a regular browser preview.

5. Debugging Android apps remotely
The top mobile app development companies will use another process to connect to an already-working
Android app. The method is relatively similar, though. The developers will start by launching the app on the
connected gadget.
To conduct the remote debugging inspection process, experts from the top mobile app development
companies will open Google Chrome and navigate to a specific section that will display all the connected
devices.
Now, they’ll click on “inspect” for the problem they want to debug. It’ll open another window with the
recognizable debugging tools of Google Chrome. The top mobile app development companies usually hide the
app preview as it doesn’t add any benefit to the debugging unless they want to use a DOM element. It reduces
the performance rate and makes it clumsy too.
At this stage, the developers should be ready to debug the app on every platform using browser-based tools.

6. Whether they store data in the localStorage of simple browsers or use Ionic Storage, developers will want to
analyze the stored information or even change it manually while developing and debugging the app.
When it comes to finding the data, developers can delve directly into the “Application” tab of the tools for
debugging. It’ll bring up every possible storage location. From this list, the specialists from the top mobile app
development companies can choose the location the app is using. If it’s Ionic Storage, they’ll find the data
below “IndexedDB.” After that, they’ll find the database’s name.
If they use Capacitor Storage, on the other hand, the data will remain inside localStorage.

7. If you hire Ionic developer, you’ll probably expect the service provider to debug the APIs when needed. If the
app connects to any APU, the developers may or may not receive and send data. Problems start when they
notice an error in red inside the log that points to an issue affecting the API call.
When you hire Ionic developer, the expert will enter the “Network” tab of the tools to check every outgoing
API call from the application.
On one side, they’ll keep tabs on the names of the various endpoints the app is contacting. On the other side,
they’ll get more tabs to check for the “header” data, the server’s “response,” and the “preview” of the
outgoing call.
Make sure to hire Ionic developer that checks all the elements in the list marked red. In reality, they must do it
thoroughly. They have to determine the reason why the API call fails depending on the “status-code” they
receive. It can also appear in the form of an “error message” present inside the server’s response.
When you hire Ionic developer, ask them about the most common problems they face regarding APIs. They’ll
say that they encounter more COR errors than anything else. However, it’s an issue affecting the server.
Developers must fix it inside the Ionic app unless they add proxy servers to their API calls.

8. If you hire Ionic developer, you have to find out whether they can debug the database files of SQLite.
Debugging Capacitor storage or Ionic Storage is easy on a browser. However, things become more challenging
if the tools use the native implementation on a device, such as the SQLite database hiding below.
Even the best developers feel nervous when debugging the SQLite database as they must extract the database
from the app to inspect the content. However, it’s possible to do it as long as you hire Ionic developer that
knows how to fix the problems affecting the data-saving logic.

9. If your app is created using Ionic 3.0 for mobile app developers, it may create specific files by itself. It can
write a few settings to keep track of content generated by users. Debugging such an app may need the
developers to see the information and gain access to the “file system.”
It sounds difficult, even to specialists who use Ionic 3.0 for mobile app developers. Nonetheless, the process
isn’t too challenging. Developers can adhere to the same processes described above for iOS to extract the
“app container” and navigate to the folder they chose for storing the documents.
If it involves Android and Ionic 3.0 for mobile app developers, the data won’t be written in the app’s folder.
Instead, it’ll remain inside a global documents folder that every app can access. Fortunately, it’s not a problem
for Ionic 3.0 for mobile app developers as it provides an excellent tool called “Device file explorer.” It lets
developers browse all the files on the connected device directly from the Android Studio.
