In web application development, securing requests between the frontend and backend is vital to prevent issues like data leaks, incorrect transactions, and outages. Key methods include using JWT tokens, HTTPS, and CSRF tokens to authenticate users and protect data. Furthermore, implementing idempotency—a property ensuring that repeated operations yield the same result—is crucial for preventing problems like duplicate transactions. The article explores various security measures and emphasizes the importance of idempotency in maintaining the integrity and reliability of web applications.
Ignoring request security can lead to data leaks, incorrect transactions, and service outages. Key measures like JWT tokens and HTTPS are essential.
Idempotency ensures that an operation can be performed multiple times without differing results, crucial for preventing issues like duplicate financial transactions.
