Resolving AWS Amplify Build Issues: How to Ensure Your Nuxt App Fails on JavaScript Errors

When deploying a web application, especially with frameworks like Nuxt.js, it’s crucial that the build process accurately reflects the code's integrity. A common frustration for developers hosting their Nuxt applications on AWS Amplify is that the build continues successfully even if there are JavaScript errors present in the code. This can lead to unforeseen issues, like a broken website, which can severely impact user experience. Almost every developer has experienced this at some point, leading to the question: How can we ensure the build fails on errors?

The Issue: Build Does Not Fail on Error

In the case at hand, the developer's build command used the following configuration:

Despite the --fail-on-error flag appearing to be set, the build commands didn’t halt on encountering a JavaScript error, which left the application in a broken state. This raises the important question: how do we ensure that build processes properly reflect failure and success status?

The Solution: A Two-Step Command

To address this issue, the suggested solution involves enhancing the build command to include a verification step. By modifying the build command, you can ensure that the operations from npm run generate are successfully completed before moving on. The adjusted command looks like this:

Why This Works

The addition of && proceed_the_CI serves as a logical operator that checks the exit status of the npm run generate command. If the command fails (i.e., if any JavaScript errors occur during the build process), the second part (proceed_the_CI) will not execute. This ensures that your Continuous Integration (CI) process respects any issues within the build phase.

Benefits of Using This Method

Error Handling: It allows for immediate error detection which can save time and resources on debugging broken builds.

Improved User Experience: When the website is ultimately deployed, users will not encounter a flawed interface.

Cleaner Codebase: You’re incentivized to maintain a bug-free code state, leading to improved quality across your application.

Conclusion

The --fail-on-error flag in AWS Amplify may create some confusion about its functionality. By incorporating the && proceed_the_CI in your build command, you can ensure that your Nuxt application’s build process catches errors and fails accordingly. This leads to a smoother development experience and a better product for users.

If you're developing in Nuxt.js and hosting on AWS Amplify, adopting this strategy will result in a more robust and reliable deployment process. Stay proactive in your coding practices, and your builds will successfully reflect the quality of your code.
