Use version control: Utilize a version control system (VCS) like Git to track the changes in your codebase. Version control enables collaboration, keeps a detailed history of changes, and makes it easy to revert to a previous version if necessary.

Automate testing: Implement automated testing to check your code’s functionality and ensure it meets the desired requirements. Write unit tests, integration tests, and end-to-end tests to cover different aspects of your application.

Continuous integration and delivery (CI/CD): Set up a CI/CD pipeline to automatically build, test, and deploy your application. It will help you catch errors early, speed up the delivery process, and ensure code quality.

Use containers: Containers are lightweight, portable, and self-contained units of software that run on any infrastructure. They make it easy to deploy applications to different environments and make it easier to manage and update applications.

Document your code: Write clear, concise comments and documentation for your code, APIs, and features. Doing this helps other developers understand your work and simplifies contributing or troubleshooting issues.

Build microservices: Microservices are small, independent services you can develop, deploy, and scale independently. Using them makes it easier to develop and maintain applications and makes applications more resilient to failures. You can read more about microservices best practices here: 11 Effective Microservices Development Best Practices.

Use cloud-native architectures: Cloud-native architectures take advantage of the scalability, elasticity, and pay-as-you-go pricing of cloud computing. Using them can help organizations save money on infrastructure costs and scale their applications more efficiently.

Prioritize security: Take security seriously from the start of your project. Follow best practices for secure software development, such as the OWASP Top Ten, and stay up to date with security updates and patches for your dependencies. 

Following these best practices ensures that your modern application is well-structured, maintainable, and scalable, leading to a more successful development experience.
