Transactions and data validation

In microservices architecture, transactions are crucial for maintaining data consistency when multiple operations need to be executed atomically. Data validation and sanitization are critical for preventing common security vulnerabilities.

Transactions in microservices

Transactions in microservices are a challenge that requires careful design and trade-offs. Transactions are operations that ensure the consistency and reliability of data across multiple systems. However, in microservices architecture, where each service has its own data store and communication is asynchronous and unreliable, implementing transactions becomes more complex and costly. There are different approaches and patterns to handle transactions in microservices, depending on the requirements and constraints of the system.

Here’s how you can handle transactions in your microservices using Node.js:

• Database support: Choose a database that supports transactions...
