Managing Environments
Flagship manages configuration settings with environment files. The files are located in the top-level env directory and use the naming syntax env.{name}.js. Each file exports a JS object that contains desired settings for the specified environment. For example, an app may have a different API endpoint between UAT and production builds.
Your app must have an environment named env.prod.js, as this is the default environment when running the app. You may have any number of other named environments.
The environment can be specified when running Flagship init by passing the --env flag. For example, to select an env named env.uat.js, run init with yarn run init --env="uat". If no env is selected, init will use the prod environment.
When running the app in RN development mode, you can use Flagship's developer menu to switch between environments.
- Tap the version number button in the bottom right of your screen
- Tap on Env Switcher
-
Select an environment
-
Review the settings to be applied and tap Switch to [...] env
- Your app will reload with the specified config
You can retrieve the active configuration by importing it from the fsapp package:
import { env } from '@brandingbrand/fsapp';You can then reference any property on the env object:
console.log(env.apiHost);You can place any key and value into the environment files, but Flagship has a number of built-in items as well. Here's a description of these items:
The internal name of your app; for example, this will be used to name the Xcode project files.
Example: name: 'BestBargains'

Example: displayName: 'Best Bargains'
