This document summarizes Irfan Maulana's presentation on architecting scalable CSS at his company Blibli.com. It discusses how they moved to using Sass and implemented the BEM methodology to modularize their CSS and make it more maintainable as their codebase grew. Some challenges included building out their own BEM libraries and integrating it with JavaScript frameworks, but overall it improved collaboration and allowed safe refactoring of CSS without side effects. The presentation concludes that scalable CSS is achievable through preprocessors like Sass and strict conventions like BEM.

- 5. OUR TOPIC TODAY Architecting Scalable CSS : Find better way to write and maintain CSS code in Large Scale Project.
- 6. Outline • Problem Analyzing • Set Goals • Finding Solution • Implementation • Challenges • Conclusion
- 7. Problem Analyzing What things do you hate when coding CSS ?
- 8. Problem Analyzing What do you think about this code ?
- 9. Problem Analyzing What about this ?
- 10. Problem Analyzing These are common problem in CSS : • Less modularity • Too much file and classes that not represent its function or places. • Tons of confusions e.g. not clear dependency (*we are afraid about removing and adding things) • Problem with scalability, consistency and on- boarding new developers. • Specificity. Too deep selector. • Have no standard. • 1 page always giving to 1 person.
- 11. Set Goals • Modular • Re-usable, Easy to extends, Easy to override • Readable and Easy Tracking • Less bloated code (Unused code) • Has Good Conventions • Easy to learn even for veteran developers
- 12. Finding Solution
- 13. Finding Solution First we found that css pre-processor is one of key to solving our css problem. CSS Pre-Processor let us to write CSS code better with more logically, re-usable function and variable, and many more advance syntax. We choose SASS as our pre-processor.
- 14. Finding Solution
- 15. Finding Solution We found many alternative for standardize our CSS code. Atomic, OOCSS, BEM, SMACSS, DRYCSS, etc. All those thing have same goals, to set a good structure in our CSS code.
- 16. Implementation • This part will not tell you the best technical part to implement the solutions. This part will tell you about our journey in implementing to our code.
- 17. Implementation • When I come to Blibli.com in 2015, Blibli.com have not implementing any cool tech in frontend side especially in CSS. • Then we choose SASS for improve our CSS code. • In the end of 2015, we migrate our retail mobile web with full SASS code.
- 18. Implementation • In early 2016, we start develop Blibli.com Pulsa with full SASS code.
- 19. Implementation • After a while, our code become bigger and complex, we face our old problem even we have implemented SASS. • In last 2016, we start develop Blibli.com Travel and trying to find another solution for fixing that problem.
- 20. Implementation
- 21. Implementation • We choose BEM and Blibli.com Travel now live in production with full BEM + SASS code • BEM offer better CSS code collaboration especially when we are in big team and complex project. • BEM works like charm with SASS advance supported.
- 22. Implementation
- 23. Implementation See full sample code here : https://github.com/mazipan/bem-kit
- 24. Challenges • Library that built in top of BEM is less, so better to build our own. • Keep BEM to be not bloated. • Make the team to have same vision. • Mixing BEM code with JS Framework that component based. • Spread an Indonesian to be mindBEMding.
- 25. Lookup Our Goals • Modular • Re-usable, Easy to extends, Easy to override • Readable and Easy Tracking • Less bloated code (Unused code) • Has Good Conventions • Easy to learn even for veteran developers
- 26. Conclusion • Scalable CSS is when your code was easy to learn, easy to maintain in the future, easy to refactor, easy to tracking the problem. • SASS (*or other pre-processor) is must when you want your CSS code become better. • Strict BEM convention make you have confidence to add/update/remove CSS without side effect.
