Visual Studio Code has a dedicated plugin for debugging apps that run in an Android WebView. The plugin creates a bridge between the device and the Visual Studio Code developer tools and permits debugging right from the editor. In order to use this plugin to debug your Ionic apps, first install it then start your app in the Android emulator or connect your Android device and run the app. Ionide is an organization which builds high quality, cross platform developer tools for F#. Our flagship project is Ionide-VSCode - a Visual Studio Code plugin, with more than 1 million downloads, transforming VSCode into a fully-fledged F# IDE. I am also running visual studio code (version 1.22.1). When I type a command in the terminal (git bash) which opens the browser, for example ionic serve the windows default browser (Google chrome) opens up. Is it possible to change the default browser for visual studio code to FireFox, while keeping Google chrome as Windows' default browser?

And then how to create and work with the Ionic 2 project using the Visual Studio Code editor. Visual Studio Code editor is an open source editor. So you can use it as free for your Ionic project development. To download the Visual Studio Code editor, please go to the below link.
Debugging a Capacitor Ionic application
Ionic documentation is increasingly recommending Capacitor over Cordova as the native runtime environment for running the applications on mobile devices. While the different approach to handling native source code in Capacitor has its advantages, the debugging experience for the TypeScript part of the applications leaves a lot to be desired.
For Cordova apps, Visual Studio Code users can install the Cordova Tools Extension and debug the Ionic application running on an Android device directly inside the text editor with minimum configuration effort:
- In the Run pane click on the create a launch.json file link and select Cordova from the list of choices.
- This will add a long list of launch configurations for Cordova apps. When the application is running, select Attach to running android on device or Attach to running android on emulator to attach the debugger to it. From here on, you can set breakpoints, inspect variables, and do everything else that the Visual Studio Code debugger supports.
As expected, these configurations don't work with Capacitor applications. Unfortunately, there's currently no Visual Studio Code extension with such functionality for Capacitor. Which leaves Chrome and Edge DevTools as the only available options for debugging. Since they are both based on Chromium, they offer a very similar experience and the choice is a matter of personal preference.
To attach the debugger to a running application, follow these steps:
- Navigate to
chrome://inspect
in Chrome (oredge://inspect
in Edge) - Wait for device discovery to complete and click on the inspect link under the entry corresponding to the device and the application you want to debug.
On the Sources tab, you can navigate the sources and set breakpoints to break the application execution. Unfortunately, source maps for (Angular-based) Ionic applications don't work, so you're stuck with transpiled and bundled JavaScript code which makes the debugging experience much worse.
However, there is a fix for that. All credit for the following instructions goes to Even Monfee. I'm including them here for convenience:
- Create a file named
attach-source-maps.js
with the following contents in the root of your project folder: - Modify the
ionic.config.json
file to include the following:
With these changes, the mapped source code of the application will be available in the
webpack://./src
folder on the Sources tab:Keep in mind that the source code is now included in the bundle and therefore significantly increases its size. Make sure you're not doing this for your production builds, either by adding a check to the script above or by removing the hook from
ionic.config.json
before starting the build.If you want to test the debugging experience yourself, you can use the code from my GitHub repository. I created two Ionic applications based on the conference starter template: one with Cordova and one with Capacitor. I added the source map fix from above to both of them.
Unfortunately, you can't debug Capacitor Ionic apps directly from Visual Studio Code yet, like you can Cordova Ionic apps. You will need to use Chrome or Edge DevTools instead. To make the source maps work with them, you can use a build hook which includes the source code in the final application bundle.
Do you use VS Code for Ionic and Angular development? Chances are good that you do. It’s a little app from the unlikeliest of companies that is becoming a big deal.
Plugin Ionic Visual Studio Code
At its core, VS Code (Code from here on), is a code editor that is free, open source, runs on multiple platforms, and has wide support for most major programming languages and environments.
It goes beyond a simple editor, though, and starts to blur the line between a lightweight editor and a full-blown integrated development environment (IDE). Code is super fast, takes seconds to install, and provides key development features most commonly found in large, commercial IDEs.
One of my favorite features of Code is its vast extension ecosystem. There are thousands of extensions out there built by the community that enhances functionality. Green light matthew mcconaughey amazon.
In this post, I’m going to share some of my favorite extensions that can help increase productivity when building Ionic and Angular apps.
Extensions for Teams
First, let’s talk about a few that will help out development teams. It is important when coding on a team that you maintain consistent coding styles and patterns. These extensions will help teams stay consistent on the really important decisions like tabs vs spaces, and if semicolons should or shouldn’t be used.
Prettier
Prettier is a library that provides consistent formatting and style choices in code. The Prettier extension for Code will read a common configuration file (.prettierrc) and apply these rules to code whenever you use Code’s built-in formatting. The rules available in Prettier aren’t numerous, but they are beneficial. Below is a sample .prettierrc file:
Wps to pdf online. This fairly common ruleset will provide some practical code formatting that your entire team will adopt. Setup Code to format on save, then formatting will always be applied, with no need to run some task to do it later!
TSLint
Where Prettier is mainly concerned with the formatting of code, TSLint rules can help enforce certain coding conventions like making sure triple equals is always used for equality checking. This helps make sure code complies with best practices decided by the team (as configured in the tslint.json file). TSLint can also fix common problems automatically:
Installing the TSLint extension shows lint errors in Code immediately, versus waiting for the build system to report them.
Note: It was recently announced by the TSLint team that they plan on deprecating TSLint and focus on making TypeScript work better for ESLint. TSLint is still a good choice, though, until the work on ESLint for TypeScript is complete.
GitLens
GitLens surfaces data from git history directly into the editing surface of Code. With it, you can easily see who last edited a particular line of code, view differences, and easily browse repos on a particular commit. There are so many features here and I only use a small subset of them (much like git itself), but it saves a ton of time when needing to view commit history.
Extensions for Development in Ionic & Angular
This next set of extensions will help in your day-to-day coding activities by streamlining development.
Peacock
If you ever work with multiple copies of Code open it can be confusing which project you are currently looking that. Peacock aims to fix that by letting you assign toolbar colors for a particular project. For instance, you can assign your Ionic project a red toolbar, and your backend Node project a blue toolbar, making it much easier to see what project you are working on in a particular window.
Auto Rename Tag
This extension is so simple it’s a wonder that it isn’t included in the default version of Code yet. With the below extension enabled, you can now rename a tag in HTML and have the closing tag rename with it:
It also works great on Ionic component tags as well.
Angular Language Service
The Angular Language Service extension is maintained by the Angular team and gives code completion and go-to definition support inside of HTML templates. No more wondering what you named that model object when trying to write our HTML!

Angular Snippets
This set of Angular snippets has long been maintained by the great John Papa from Microsoft. Updated with each version of Angular, you will find dozens of snippets (bits of code that can quickly generate by typing a simple command) for the most common Angular tasks.
Ionic 4 Snippets
Much like the Angular snippets, this gem will complete Ionic component tags in your HTML quickly as well as some special snippets for code and CSS files. This extension saves on having to go back and forth on the docs so much. If you are still on Ionic 3, search for Ionic 3 snippets.
Angular2 Switcher
Of all the Angular based extensions, this one is perhaps my favorite. It allows you to quickly switch back and forth between the HTML, code, and CSS files that make up your component with quick keystrokes.
While the switching between files is a nice time saver, another feature this extension has is the ability to either cmd/ctrl+click (or hit f12) on variables and functions in HTML to quickly take you to the definition for them in the code file.
Code Spell Checker
This one is self-explanatory but extremely helpful: It catches spelling mistakes in code files. Often I find this helps catch unintended bugs by making a typo in a variable name that TypeScript wouldn’t otherwise catch (like in templates).
Wrapping Up
Ionic Capacitor Debug Visual Studio Code
Code is a great editor for any development project. With a vast ecosystem of extensions and plugins, you can greatly customize your development environment. Have any favorite extensions that I didn’t cover here? Post them in the comments down below!
Ionic Preview Visual Studio Code
If you are looking for a more full-featured app builder for working on Ionic apps, then you might be interested in Ionic Studio. It shares many similarities with Code but offers a deeper integration into Ionic with a drag and drop interface, a properties editor, and on-device testing for quickly building out Ionic apps.
