4. FIRST OF ALL

5. WHAT IS A SPA?

6. SPA
A WEB
APPLICATION
IN A SINGLE
WEBPAGE WITH
SIMILAR
EXPERIENCE OF
A DESKTOP
APPLICATION

7. DO YOU EVEN
REACT BRO?

8. COMMON
PROBLEMS

9. BACK BUTTON

10. SCROLL POSITION

11. ROUTING

12. LOAD TIMES

13. ACCESSIBILITY

14. WHY WOULD YOU
BREAK THE WEB?

15. HOW MUCH WILL
COST TO BREAK THE
WEB?

16. THERE IS A
MINIMUM
EXPERIENCE IN THE
WEB

17. OH WAIT! THERE IS
WAYS TO GET
AROUND MOST OF
THESE PROBLEMS

18. IS THE BUSINESS OK
WITH THIS EXTRA
COST?

19. EVERY FEATURE
NEEDS A STATE AND
ALL THE
APPLICATION
BEHAVIOR?

20. IS THIS STATE
ABOUT BUSINESS
RULES OR IS IT JUST
A CSS
CONTROLLER?

21. IS THIS THE A WEB
SITE?
IS THIS JUST AN
APPLICATION?

24. YOUR COMPONENT
IS A PARTIAL

25. NEW
DEVELOPERS

26. OVERHEAD

27. OVER
HEAD
EVERYTHING
THAT A
DEVELOPER
NEEDS TO HAVE
IN MIND WHEN
WRITING CODE

28. SPA
OVER
HEAD
2ND -
LANGUAGE
ECOSYSTEM
FRAMEWORK
APPLICATION
ARCHTECTURE

29. SO...

30. THE BUSINESS
WANT A WEBSITE
OR AN
APPLICATION?

31. DOES THE BUSINESS
WILL GIVE UP TIME
TO SOLVE THOSE
PROBLEMS?

32. DOES THE BUSINESS
HAVE THIS TIME TO
GIVE?

33. IS SEO IMPORTANT?
IF SO SHOULDN’T IT
BE A PRIORITY?

34. SORRY, BUT
I REPEAT

35. THE PRODUCT IS A
APPLICATION?

36. PROBABLY YOU ARE
NOT SPOTIFY OR
FACEBOOK

37. YOUR APPLICATION
SHOULD REFLECT
THE PRODUCT AND
THE COMPANY

38. NOT THE DEV
DREAM STACK
