What is Capacitor-updater?
Capacitor-updater, a technology that helps in the delivery of app updates and improvements to the end users instantly.
This is especially great if you want to do critical bug fixes and deliver instantly without going through the App Store reviews.
You can think of it as “web-like” agility of side-loading updates as soon as they are available.
Moreover, it provides rollbacks if the new update crashes the app
How does it work?
I use Capgo in all my projects I build. That allows me to put less time in the App Store review process.
You can read more about it here.
Are there any limitations?
As good as it may sound, there are a few things that we need to keep in mind. The first thing is that OTA updates only work with web bundles. You may think that this isn’t really a big limitation because, in Capacitor JS, we write almost all code in JS CSS and HTML. While this may be true, there still are native modules that we install to our app. If a module changes your android or iOS directories, you can’t use OTA to update your app. That’s because these directories’ contents are used to compile Native binaries, which OTA can’t update. Even native app cannot update this part.
Let’s get started 🚀
It’s time to sign up, and get your API key to upload your first version! Begin by signing up for a Capgo account.
Once you’re logged into Capgo, You will have an onboarding page
Follow the steps on the onboarding page to add your first app.
Install the Capgo SDK
From a command line, directly into the root of your Capacitor app, run:
npm i @capgo/capacitor-updater && npx cap sync
To install the plugin into your Capacitor app.
And then add to your app this code as a replacement of CodePush one:
This will tell the native plugin the installation as succeeded.
Login to Capgo CLOUD
First, use the
all apikey present in your account to log in with the CLI:
npx @capgo/cli@latest login YOU_KEY
Add your first app
Let’s get started by first creating an app in Capgo Cloud with the CLI.
npx @capgo/cli@latest app add
This command will use all variables defined in the Capacitor config file to create the app.
Upload your first version
Run the command to build your code and send it to Capgo with:
npx @capgo/cli@latest bundle upload
By default, the version name will be the one in your
Check in Capgo if the build is present.
You can even test it with my mobile sandbox app.
Make channel default
After you have sent your app to Capgo, you need to make your channel
default to let apps receive updates from Capgo.
npx @capgo/cli@latest channel set production -s default
Configure app to validate updates
Then do a
npm run build && npx cap copy to update your app.
Receive a Live Update on a Device
For your application to receive a live update from Deploy, you’ll need to run the app on a device or an emulator. The easiest way to do this is simply to use the following command to launch your local app in an emulator or a device connected to your computer.
Open the app, put it in the background and open it again, you should see in the logs the app did the update.
Congrats! 🎉 You have successfully deployed your first Live Update. This is just the start of what you can do with Live Updates. To learn more, view the complete Live Updates docs.
