A one day, single-track online event celebrating the future of cross-platform app development
There are two ways to start using Capacitor: adding Capacitor to an existing frontend project (recommended), or starting a fresh project. Capacitor was designed primarily to drop-in to existing frontend projects, but comes with a simple starting project structure if you’d like to start fresh.
Capacitor provides a native mobile runtime and API layer for web apps. It does not come with any specific set of UI controls which you will most likely need unless you’re building a game or something similar.
We strongly recommend starting a Capacitor project with your mobile frontend framework of choice (such as Ionic Framework).
Make sure you have all the required Dependencies installed for the platforms you will be building for. Most importantly, make sure you update CocoaPods using
pod repo update before starting a new project, if you plan on building for iOS using a Mac.
package.json file and a folder containing all web assets are required to get started. In addition, a
<head> element is needed in the main
index.html file, as Capacitor is injected there upon app initialization.
To add Capacitor to your web app, run the following commands:
cd my-app npm install @capacitor/core @capacitor/cli
Then, initialize Capacitor with your app information.
npx is a new utility available in npm 5 or above that executes local binaries/scripts to avoid global installs.
npx cap init
This command will prompt you to enter the name of your app and the app id (the package name for Android and the bundle identifier for iOS). Use the
--web-dir flag to set the web assets folder (the default is
Next, install any of the desired native platforms:
npx cap add android npx cap add ios
🎉 Capacitor is now installed in your project. 🎉
Capacitor comes with a stock project structure if you’d rather start fresh and plan to add a UI/frontend framework separately.
To create it, run:
npx @capacitor/cli create
This command will prompt you to enter the name of your app and the app id (the package name for Android and the bundle identifier for iOS).
This will create a very simple starting app with no UI library.
