CLI

Usage

All command should be run in your app folder with capacitor project ignited. See below.

Capacitor: Cross-platform native runtime for web apps

Init

npx @capgo/cli init [apikey]

This method is here to onboard you step by step.

It will add your app to Capgo. It will add the code to your app to validate the update. Likewise, it will build your app. Furthermore, it will upload your app to Capgo. And it will help you to check if the update works.

npx @capgo/cli login [apikey]

This method is here to remember the apikey for you.

Optionaly you can give:

--local This will store your apikey in the local repo and git ignore it.

--path [/path/to/my/bundle] to upload a specific folder.
--channel [test] to upload to a specific channel.
--external="https://mydomain.com/myapp.zip" to link to an external URL instead of upload to Capgo cloud, it should be a zip URL in HTTPS.

--bundle-url prints bundle url into stdout. Useful when parsing bundle url from shell.
--no-code-check to ignore the code check and send the bundle anyway.

⭐️ External option helps to unlock 2 cases: corporate with privacy concern, don’t send the code to a third part and app bigger than 200 MB. With this setting, Capgo store only the link to the zip and sends the link to all apps.

👀 Capgo cloud never looks at what is in the link (for external option), or in the code when stored.

🔑 You can add a second layer of security by using encryption, then Capgo will not be able to look or modify anything, it becomes “trustless”.

Example of package.json for version

{
  "version": "1.0.2"
}

⛔ Version should be greater than “0.0.0”.

💡 Don’t forget to update the version number each time you send one, version number cannot be overrode, or reused after deletion for security reason.

Disable updates strategy

There are a few ways to handle disabling updates for too old versions.
Capgo cannot update native code thus an update from a version with the old native code to a version with the updated native code should not be possible. There are a couple of ways to achieve that.

First, the major strategy. It prevents an update from 0.0.0 -> 1.0.0. The major is the highlighted number (1.0.0 and 0.0.0).
Second is the minor strategy. It prevents an update from 0.0.0 -> 1.1.0 or an update from 1.1.0 to 1.2.0. BE AWARE this strategy does not prevent an update from 0.1.0 -> 1.1.0

Third, the patch strategy. It was added into capgo as a very strict mode. It’s not recomended to be used unless you fully understand how it works. In order for it to accept a update the following conditions must be meet:

The major is the same between the new and the old version
The minor is the same between the new and the old version
The patch of the new version if greater then the patch of the old version

Here is an example of which scenarios the update is allowed or denied

0.0.311 -> 0.0.314 ✅
0.0.0 -> 0.0.314 ✅
0.0.316 -> 0.0.314 ❌
0.1.312 -> 0.0.314 ❌
1.0.312 -> 0.0.314 ❌

Lastly the most complicated strategy. The metadata strategy.
First you need to know that initially after you enable it the updates WILL fail as the channel is lacking the required metadata.
If the channel is lacking metadata you will see a message like this:

If you see something like this you know that you have to go to the current bundle for the failing channel and set the metadata.
First, figure out what channel is failing. You can do that by looking at the misconfigured column

Then go to the failing channel and click on Bundle number. This should take you to the bundle page.

Once there fill the Minimal update version field. This should be a semver.
If the value you pass is not a semver you will get an error, but if everything goes correctly you should see something like this:

Now, you likely do not want to set this data manually every time you update. Fortunately, the CLI will prevent you from sending an update without this metadata

To properly upload a bundle when using the metadata option you need to pass the --min-update-version with the valid semver. Something like this:

The --min-update-version is not the ONLY way to do compatibility. There also exists the --auto-min-update-version. Here is how it works.

First, it takes a look at the version curently uploaded to the channel. It checks compatibility same as bundle compatibility command would. Second, if the new version is 100% compatible it reuses the min_update_version from the latest version in the channel. If not, then it sets the min_update_version to the bundle number of the newly uploaded version.

You will always get an information what is the min_update_version when using this option. It will look something like this:

If the new version is not compatible it should look something like this

End-to-End encryption (Trustless)

Capgo supports end-to-end encryption, this means that your bundle(code) is encrypted before sent to the cloud and decrypted on the device. For that, you need to generate an RSA key pair, you can use the following command to generate it.

The encryption system is a combination of RSA and AES, the RSA key is used to encrypt the AES key, and the AES key is used to encrypt the file.

See below for more information about the encryption system.

Create key for your app

npx @capgo/cli key create

Optionally, you can give: --force to overwrite the existing key. This command will create for you a key pair in your app, and will ask you to save the private key in a safe place. It’s recommended to not git commit the private and public key, and to not share it with anyone.

After your local test, remove the key from the config file and add it on the CI step with key save

Save key in your app config

npx @capgo/cli key save

Optionally, you can give:

--key [/path/to/my/private_key] the path of your private key.

--key-data [privateKey] the private key data, if you want to use inline. This command is useful if you followed the recommendation and didn’t commit the key in your app, and in the config.
