EAS Update not working EXPO_ROUTER_APP_ROOT is not defined

No response

Summary

I recently switch using default Expo environment variables for eas. So i defined all my env variables in my eas.json. Since i made that change, eas update is no longer working.

Running: eas update --branch preview --platform ios doesn't work anymore.

eas build and local development is working fine tho.

Managed or bare?

Reproducible demo or steps to reproduce from a blank project

1. Setup base project
2. init eas and set environment variables for each profile
3. run an eas update

I found the problem:

in front of my eas command, i had this:

NODE_ENV=test eas update --branch preview --platform ios

which was not required anymore because i was using the env in the eas.json and not my .env.test

And i saw in the expo router code that the EXPO_ROUTER_APP_ROOT is ignore in test.

   // Skip loading the app root in tests.
          // This is handled by the testing-library utils
          process.env.NODE_ENV !== "test" &&
          t.isIdentifier(parent.node.property, {
            name: "EXPO_ROUTER_APP_ROOT",
          }) &&
          !parent.parentPath.isAssignmentExpression()
        ) {

I remove the NODE_ENV=test and everything is good.

How can we handle a staging .env file ? i tried using .env.staging but expo throw that this file is not supported..

NODE_ENV=staging at the build time, it will load env from .env.staging , I am also going to implement this in this week.

@agrittiwari it doesnt work if you use eas cli because .env.staging is not a supported file. Im getting an error message saying this.

You can only use

.env.production .env.test .env.development

and same with additionnal .local extension

[amandeepmittal]

Expo CLI loads .env files as per the standard defined by the file resolution here based on their priority reference. It's also covered in the docs here.

As per that standard, .env.staging is not supported.

Hey @oliviercperrier have you find a way to work around this? I was also using NODE_ENV=test as staging to load variables and build failed with the expo-router error.

I'm also facing a similar issue, but I'm not using EAS. I need to load my test environment variables when running start, run and so on... Example NODE_ENV=test expo run:ios. But I'm just presented with this error:

error: node_modules/expo-router/_ctx.ios.js: node_modules/expo-router/_ctx.ios.js:Invalid call at line 2: process.env.EXPO_ROUTER_APP_ROOT
First argument of `require.context` should be a string denoting the directory to require.

standard .env is not enough. NODE_ENV=test behaviour seems different so it's not suitable to replace staging env. Hope expo can support more in EXPO_PUBLIC.

You da real MVP!
