Understanding URL Encoding
Encoding Methods
- encodeURIComponent(): Encodes all special characters including reserved ones like ?, &, =, and /. Best for individual query parameter values.
- encodeURI(): Preserves URL structure characters (/, ?, #, etc.) while encoding spaces and other special characters. Best for complete URLs.
- Query String Parser: Parses key-value pairs in query strings and properly encodes each component separately.
- Percent Encoding: Uses %XX format where XX is the hexadecimal ASCII code of the character.
- UTF-8 Support: Properly handles international characters and emoji in URLs.
Common Use Cases
- Encoding query parameters before adding them to URLs
- Building dynamic URLs with user input or form data
- Decoding URLs received from external sources or APIs
- Debugging URL-related issues in web applications
- Creating SEO-friendly URLs with proper encoding
