Fatal error when a variable with the same name as expanded variable is declared

[hpedrorodrigues]

Hey 👋🏻

Context

A RangeError (more specifically Maximum call stack size exceeded) is raised when we declare a variable with the same name as the expanded variable.

e.g.,

MY_VAR=${MY_VAR}

If we change the value to something else. It works just fine.

This is an issue in dotenv-expand, and it was fixed in 11.0.0 (more details in the linked issues).

Description

Even though the issue is already fixed in dotenv-expand, we still use version 5.1.0 here.

vite-plugin-env-compatible/package.json

Line 48 in 12cd100

"dotenv-expand": "5.1.0"

Also, since 5.1.0 is not compatible with version 11.0.0 (as expected 😅), we cannot force a resolution to 11.0.0 in the user project.

Solution

We need to bump dotenv-expand to at least 11.0.0 to fix this issue.

In the meantime, we can declare variables this way, and it should work:

MY_VAR='\${MY_VAR}'
