Why is Server-Side Compilation Recommended for SASS.js?

Parsing SASS with SASS.js

While the syntax of LESS.js and SASS may seem similar, the implementation of SASS.js differs significantly. Unlike LESS.js, SASS.js is primarily intended for Node.js usage. This means that the approach used with LESS.js is not directly applicable with SASS.js.

Concerns with Client-Side SASS Compilation

While it is possible to compile SASS client-side, it raises several concerns:

• User Compilation: Requiring users to compile your stylesheets themselves increases the load on their browsers.
• JavaScript Dependency: If JavaScript is disabled on a user's browser, your site will appear unstyled.
• Server-Side Conversion Complication: If you decide to switch to server-side compilation later, you would need to modify all your templates to accommodate the change.

Recommendation

The SASS core team strongly recommends using server-side compilation as the preferred approach. This approach ensures that all browsers can load your site correctly and simplifies potential changes in the future.

Alternative Implementations

While there are no official JavaScript implementations of SASS, there are ongoing developments in the community. However, it is advised to use caution when considering these implementations until they have been fully tested and proven reliable.
