Solving Firebase CLI Deploy Errors Related to Node.js Versions

If you are a developer working with Firebase, you may have encountered the frustrating error message that states: "Deploys to runtimes below Node.js 10 are now disabled in the Firebase CLI." This issue typically arises after updating the Firebase CLI, and it can hinder your ability to deploy essential Cloud Functions for your applications. Fortunately, there is a workaround that will allow you to continue deploying your functions without losing functionality or incurring costs prematurely.

Understanding the Problem

The Firebase CLI recently enforced a restriction on deploying Cloud Functions using Node.js versions lower than 10. This change means that if your project’s package.json file specifies Node.js 8 as the supported runtime, you will encounter deployment errors. Here’s a summary of the key points to keep in mind:

Node.js 8 is Unsupported: As of March 15, 2021, any existing functions deployed using Node.js 8 will stop executing.

Firebase CLI Version Impact: After updating to version 9.0.0, the Firebase CLI no longer supports deploying functions using Node.js 8.

Payment Plan Limitations: If you are using the Spark payment plan, you may wish to delay upgrading Node.js to avoid billing changes.

Steps to Resolve the Issue

Option 1: Upgrade to Node.js 10 or Higher

The recommended approach is to update your project’s functions to use Node.js 10 or a later version. However, moving to a newer version may require changing your payment plan from Spark to something that includes billing. If you're ready to take that step, you'll need to:

Update the engines field in your package.json to specify the desired Node.js version (10, 12, or 14).

Test your functions locally to ensure compatibility with the new version.

Deploy the updated functions using the Firebase CLI.

Option 2: Downgrade Firebase CLI

If you cannot immediately upgrade your Node.js version due to plan limitations or other constraints, you can temporarily downgrade your Firebase CLI to continue using Node.js 8 without immediate payment implications. Here’s how to do that:

Open your command line interface.

Run the following command to downgrade to the latest compatible version of the Firebase CLI (before version 9):

This will install version 8.20.0 of the Firebase CLI, allowing you to deploy your functions still relying on Node.js 8 until March 15, 2021.

Conclusion

In conclusion, while the Firebase CLI has moved on from Node.js 8 support, you don't need to panic about immediate action if you're on the Spark plan. By either upgrading to a supported Node.js version or temporarily downgrading your Firebase CLI, you can continue to deploy your functions without issues. Make sure to plan your upgrades accordingly to ensure smooth functionality and avoid sudden disruptions in your Firebase services.

Remember that keeping your dependencies and runtime versions up to date is crucial for maintaining security and performance in your applications. As always, happy coding!
