Vite env Variable Undefined after Converting CRA to Vite | Vite env Variables Not Working

If you have recently converted your Create React App (CRA) project to Vite, you may have encountered issues with environment variables not working as expected. This can be frustrating, especially if your project relies on these variables for configuration and functionality.

One common issue that developers face after converting from CRA to Vite is undefined environment variables. This can happen for a few different reasons, but it is important to understand how Vite handles environment variables and how they differ from CRA.

Understanding Vite Environment Variables

In Vite, environment variables are accessed using the `import.meta.env` object. This provides access to variables defined in the `.env` files as well as system environment variables. Vite handles environment variables differently than CRA, so it’s important to update your code to use the new syntax and structure for accessing these variables.

Common Issues with Vite Environment Variables

After converting from CRA to Vite, developers often encounter issues with environment variables being undefined. This can be due to incorrect syntax or usage of the `import.meta.env` object, or it could be related to differences in how Vite processes and bundles the environment variables.

Resolving Undefined Environment Variables

If you are experiencing issues with undefined environment variables in Vite, there are a few steps you can take to troubleshoot and resolve the issue:

• Double check your `.env` files to ensure that the variables are properly defined and have the correct syntax.
• Make sure that you are accessing the environment variables using the `import.meta.env` object in your code.
• Check for any differences in the way Vite handles and processes environment variables compared to CRA.
• Consult the Vite documentation and community resources for tips and best practices for working with environment variables in Vite.

Conclusion

Converting from CRA to Vite can bring about changes in how environment variables are handled and accessed in your project. If you are encountering issues with undefined environment variables after the conversion, it is important to understand how Vite handles environment variables and to make the necessary updates to your code to ensure they are working properly.
