What is CORS and why is it important in web development?
CORS stands for Cross-Origin Resource Sharing. It's a security feature that allows or restricts resources requested from another domain. It's important because it helps prevent malicious websites from accessing sensitive data.
How does CORS work in frameworks like Express and Django?
In Express, you can use the 'cors' middleware to enable CORS easily. In Django, you can use the 'django-cors-headers' package to manage CORS settings.
Are there any common issues developers face with CORS?
Yes, common issues include misconfigured headers, preflight request failures, and browser caching problems.
Can you give me an example of how to set up CORS in a Flask application?
Sure! In Flask, you can use the 'flask-cors' extension. Just install it and use CORS(app)
to enable CORS for your app.
