Getting release channel in app

Expo SDK
1

SDK version: 23.0.0

$exp --version
46.0.5

I’ve built an app using:

exp build:ios --release-channel staging

and

exp publish --release-channel staging

However, the releaseChannel is not in Expo.Constants.manifest as stated in docs.

I need it to be able to pull out certain configs specifically for each environment. I.e:

import Expo from 'expo';
const { Constants: { manifest } } = Expo;
const releaseChannel = manifest.releaseChannel || 'default';

const config = {
    default: {
        API_BASE_URL: 'my-dev-url',
        [some default configs]
    },
    staging: {
        API_BASE_URL: 'my-stage-url',
        [some staging configs]
    },
    production: {
        API_BASE_URL: 'my-production-url',
        [some production configs]
    }
}[releaseChannel];

hi @tommyy - this should be fixed now. You may need to republish to trigger a pull from the server in order to see the changes in the manifest.

Hi, just want to confirm why releaseChannel is not in the manifest object in the docs: https://docs.expo.io/versions/latest/workflow/how-expo-works/#expo-manifest

releaseChannel is not in the manifest object in __DEV__ mode, are you seeing this in production?

10

yes I am

11

Are you accessing it like Constants.manifest.releaseChannel?

12

yes I am. I know that in production, releaseChannel will be available. I think it should be part of the manifest object in the Expo docs(https://docs.expo.io/versions/latest/workflow/how-expo-works/#expo-manifest) . I am using flow to handle types in my codebase. I get an error regarding releaseChannel because the there is no type for it in the expo-constants flow-typed definitions(https://github.com/flow-typed/flow-typed/blob/master/definitions/npm/expo-constants_v5.x.x/flow_v0.69.0-/expo-constants_v5.x.x.js)

I also vote for it being part of the documentation.
