React for non techies
- 2. React is taking over...
- 3. React is everywhere... ¡ñ We¡¯ve been using it on every client project during the last 18 months. ¡ñ London React Meetup hosted by Red Badger has 2000+ members. ¡ñ 5th most starred project of all time on Github behind Bootstrap, D3, Node & jQuery
- 4. ¡ñ ¡®React is something cool you can use to create UI but we don¡¯t know why it¡¯s good.¡¯ - Non techie ¡ñ ¡®A javascript library for building user interfaces. The V in MVC.¡® - Facebook React Developers But what is it? ¡ñ The best tool developers currently have for organising the front end code.
- 5. Backend Prepares data that should be sent to user and determines what front end code should go with it: What is the frontend exactly? User types fortnumandmason.com in web browser, request sent to our server CLIENT SERVER Frontend Adds data to HTML and JavaScript files, sends those files with CSS to the user Frontend Adds data to HTML and JavaScript files, sends those files with CSS to the user ? React helps us organise and build this
- 6. ¡ñ jQuery ¡ñ Backbone, Ember, Angular and more... ¡ñ All provide a solution ¡ñ React was easy to pick up ¡ñ Promotes idea of breaking down UI into components ¡ñ Big company backing Not the first solution, probably not last
- 7. ¡ñ A few lines of JavaScript that defines how an element of the page should behave. ¡ñ We can position it on the page and style it too.. ¡ñ Facebook recommend slicing the design into React components What is a React component?
- 8. Business Requirement ¡°We want to show a number!¡± React: Example 1 http://codepen.io/anon/pen/QjzwdE ¡ñ Props ¡ñ Render ¡ñ Default Values ¡ñ Validations of prop data types ¡ñ React forces code structure. 10
- 9. Business Requirement ¡°We want to be able to increase that number!¡± React: Example 2 http://codepen.io/anon/pen/epQXZN ¡ñ State
- 10. Business Requirement ¡°We want to have re-usable components so that other teams can use what we are building!¡± React: Example 3 http://codepen.io/anon/pen/EVOMNg ¡ñ Separation of concerns ¡ñ Re-use
- 11. ¡ñ Clear structure and organisation of UI ¡ñ Encourages code re-use ¡ñ Fun! (inspired by game programming) ¡ñ Lifecycle - you can do stuff before and after a component appears on the page ¡ñ Small components are more testable ¡ñ Abstracts some browser differences ¡ñ Challenges: A single component is simple but constructing a large system of components and co-ordinating their communication is complex Patterns for managing state still being figured out. (Arch, Flux, Relay, Redux etc. etc.) Developer perspective
- 12. UX, Design & Dev collaboration ¡ñ Lloyds UXD started slicing components at design stage with developers. Worked well. ¡ñ Shared terminology, better communication. ¡ñ UX/Designers already think this way? ¡ñ Brings development process closer to design process?
- 13. ¡ñ Makes the front end easier to understand, debug and iterate on. ¡ñ Reduces communication barriers between Design and Development ¡ñ Common structure and patterns so developers can take our knowledge with us to old and new projects. Benefits to clients Faster Delivery Higher Quality
- 14. Next steps... ¡ñ What can we do as Red Badger teams? ¡ð Regular team huddles during design stages to review Sketch files. ¡ð Break the design down into components. ¡ð Translate them to code. ¡ð Reference them in future designs . ¡ñ Remember the only constant is change, who knows what tech will be using in 1 year, we have to continually adapt our process and technology, More communication will help us evolve.. ¡ñ But right now, it feels like we are in the right place...
