About URL Encoding/Decoding
What is URL Encoding?
URL encoding converts special characters in URLs to a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits representing the character's UTF-8 encoding.
Two Types of URL Encoding
- encodeURI: For encoding a complete URL, preserves characters like :, /, &, =
- encodeURIComponent: For encoding URL components (like query parameters), encodes characters like /, &, :, =
Common Use Cases
- Making URLs safe for transmission in HTTP requests
- Encoding form data in query parameters
- Ensuring special characters are properly represented in URLs
- Creating valid URLs from user input containing spaces or special characters
- Handling internationalized domain names and paths
