Relative vs Absolute Paths in JavaScript

JavaScript employs both relative and absolute paths to specify the location of resources like images, scripts, or other external assets. Understanding the differences between these paths is crucial for effective web development.

Definition

• Relative path: A path that refers to a file or resource relative to the current directory. It does not include the full path from the root directory but instead uses the current directory as the starting point. For instance, "./kitten.png" is a relative path that represents the image file "kitten.png" located in the same directory as the script.
• Absolute path: A path that specifies the entire file or resource location starting from the root directory. It includes the protocol (e.g., "http" or "https"), domain name, and the full path to the resource. For example, "http://www.foo.com/images/kitten.png" is an absolute path that points to the image file on the server hosted at "www.foo.com".

Performance and Security

Generally, there are no significant performance differences between using relative and absolute paths. However, if the resources are located on a different domain, absolute paths may incur additional overhead due to cross-origin requests.

In terms of security, absolute paths can help prevent malicious actors from accessing unauthorized files by restricting access to files within the site's hosting. Relative paths, on the other hand, can potentially be manipulated to point to unintended files if the current directory is compromised.

Converting Absolute to Relative Path

JavaScript provides utilities to convert absolute paths to relative paths:

• URL.createObjectURL(file): Creates a temporary URL to a Blob object, which can then be used as a relative path to the file.
• URL.relative: Returns a relative URL between two absolute URLs.
