Aside from configuring the . npmrc file , there are other best practices you should follow to ensure a smooth deployment on Elastic Beanstalk:
Constant review of dependencies
It is essential to review the application's dependencies regularly and ensure that they are up-to-date and well-organized in package.json . In addition, key dependencies required for both development and production should be clearly separated, avoiding including unnecessary dependencies in production.
Logs and error monitoring
During deployment, I believe it is essential to enable a good denmark mobile numbers list logging system to monitor errors in real time . In Elastic Beanstalk, Nginx and application logs should be reviewed periodically to identify and troubleshoot potential configuration or execution errors.
eb logs
This command allows you to review the instance logs and find details about errors that may be affecting the operation of the application, such as connection problems (error 502) or missing dependencies.
Validating the local environment before deployment
Make sure your application works correctly in the local environment before deploying. Testing the entire npm install , npm run build , and npm start flow in a production-like environment helps you identify and fix potential issues before pushing it to Elastic Beanstalk.
Documenting the deployment flow
It is good practice to document the entire deployment process, including any additional steps that need to be performed, such as manual installations or environment-specific configurations. This ensures that in the event of future issues, you can follow a clear process to reproduce or fix errors.
Deployment Automation
Leveraging deployment pipeline automation through custom scripts or CI/CD (continuous integration/continuous deployment ) tools can improve efficiency and reduce human error. Elastic Beanstalk facilitates this automation through the use of configuration files (such as Procfile) and integration with the EB CLI.
By following these recommendations and adjusting the .npmrc and package.json configurations , we were able to avoid critical errors during deployment and ensure that the application worked correctly on Elastic Beanstalk. Having a good understanding of how dependencies and configurations work in the cloud is key to maintaining a smooth and uninterrupted deployment flow.
