==
what i sreact and why we need react
=
what are the challenges in modern web development
==
react becomes more popular from 214
before that there is no internet
there is no website
netflix is designed with react
amazon is designed with react
=
why react is trending from 2014
=
from 1999 we have browser
we hve web applicaitons
why suddenly trending from 2014
modern web userrs are using we from smart devices
80 percent users from mobile only right from smart devices only like tab
earlier u hve to vicist a net cafe , u need to pay hourly 10 rupes
becuase this less traffic earlier
we need unified user experience
for example we have youtube
watchignthis on pc or tab
diferetn devices diferent dimensions
we have to optiomise size to fit on mobile ( compress previosuly)
m.facebook.com, diferent devices diffent domains
when application is optimisd, mobile users unable to certain facility
u have ms office in ur lappy and in mobile
mobile in ms ffice -> severla options is not avaialble
when watching from mboile -> restrictting some acces
that is not good
->
now mobile has same experince like all devices
unified expericne -> in all devices all options avaialble
===
unified ux
====
fluid user expericnce
==
iam using google
imaging this on mobile
some list came after browsing
in that pagination -> iam scrolling down to reach so amny pages
if this watch on mobile -> it is very small, how to click on that small siz e
->
zoom and click
-> that ui developed font and sizes based on the mobile
every one can see
not zoom and click
=> in images, auto images loading
==>
to developing like this it is more difficult
==>
these are challenges
===>
loosely coupled and extensible
=>
one new feature is created,
sepertely developed after all tetings
it
new feature developed , to integrate it into production app
customer will have to reinstall the application
its not good
automaticlly comes
catastropic falures -> it cannot integrate that new feature
aftre installing software -> in os, os gets technical issues
that should not happen
====
without stopping the application -> new features have to integrate -> loosely coupled and extensible architecture
===
what is a solution for ths
as a developer what is the solutiin
- better to build spa -> single page applicaitons
what is isngle page applications have unified expericne
spa has fluid experence
spa has loosley coupled and extensible
difference between ordinar y and spa
index page
=> login. register
=> click on login -> redirect to some other page
login -> spa-> it is designe as componentin a page ,
its not another page in spa
===
component level develop is goo d
