Chapter 1: Introduction to JavaScript Interview Preparation
Welcome to Day 38 of your 100 Days of JavaScript Interview Preparation! This guide is designed for beginners aiming to master the essential concepts of JavaScript, particularly focusing on the Content Security Policy (CSP).
Understanding the Content Security Policy (CSP)
On Day 37, we explored the fundamentals of CSP. Let’s dive into how to effectively implement CSP in your HTML code.
Here's how to set up CSP:
default-src: This directive establishes the default policy for all resource types, including scripts, stylesheets, and images, unless a more specific directive is defined.
This allows resources to load only from the same origin ('self').
script-src: This directive defines which sources can load JavaScript.
style-src: This directive specifies the sources allowed for loading CSS stylesheets.
font-src: This directive identifies the sources from which fonts can be loaded.
img-src: This directive specifies the allowed sources for loading images.
Images can be loaded from the same origin ('self') and data URIs.
For more examples and explanations, explore the resources below. Happy coding, and stay tuned for more insights!
