Getting started

To use this tool, you will need to setup authentication with github tokens first.

  1. Have access to the SpringTree Solutions organization on github
  2. Create a github personal access token for the eva-cli to confirm you have access. The token will require the read:org and read:user scopes, see github creating a personal token guide for more information here
  3. Once you have the token, store it using the set-token command like so
eva set-token --token=TOKEN_HERE

If you ever need to verify if your token is still valid you can use the verify-token command like so.

eva verify-token

You can now use the tool in any eva cli project, which require a eva-cli.json in root of the project. Which looks like so, every key in this object is explained in the eva-cli section down below.

    "version": 1,
    "assets": {
        "appIcon": "src/assets",
        "appLogo": "src/assets",
        "appSplashScreen": "src/assets",
        "appSplashScreenGif": "src/assets",
        "colors": "src/theme",
        "eva-config": "src/assets/env"
    "framework": "ionic",
    "projectName": "eva-companion-app"


Once the eva-cli.json is configured correctly, and you are authenticated successfully you can use this tool by running the switch command.

eva switch

This will let you choose interactively choose a customer and target.

CI setup

For CI, you won't be calling set-token but the switch:ci command with same flags as the regular switch command. For authentication it will either look at the EVA_SWITCH_TOKEN environment variable or you can pass the token as a flag like so.

eva switch:ci --token=TOKEN_HERE

eva-cli.json file

The eva-cli.json file holds the configuration which the eva-cli will look at once executed, it will help the tool determine which project its being used in and which assets to fetch.

'assets' key

The assets object key will represent any project's assets defined in on the customer manager here. The key will essentially be used as an identefier to find the matching customer project asset which will be uploaded on the customer manager as well under https://eva-customer-manager.firebaseapp.com/customers/details/:customerId/:projectId The value of any key under assets will be the path where you would like to copy the uploaded asset. The copied file name will be equal to the asset id regardless of the original uploaded file name.

'eva-config' Asset key

The eva-config key here is a special one, as its a preserved key for the selected target which gets written under the file name eva-config.json

'framework' key

The framework key can be any of the values of 'ionic' | 'angular' | 'flutter' | 'react' | 'xcode' to help collect usage data and have framework specific behavior in the future.

'projectName' key

the projectName needs to be an existing project under projects in the customer manager. It will be used by the eva-cli to show you relevant customers for this project.

'postSwitchScriptPath' key

The postSwitchScriptPath needs to be a relative path of an executable script which will be executed once the switch mechanism is finished. This script will be passed the eva-cli.json as argument.


These are the possible commands in a nutshell as outlined here above.
