Hello,
I'm a GWT newbie. I've read the GWT docs and played with the samples,
but still i have some basic questions about how to design and use GWT
in a web app:
1) GWT communicates asynchronously with a server. When a GWT
application loads, i would like to be able to display some initial
data without going back to the server (after all, we've just been
there:). How/where can i pass some initial data and what method do i
use to feed it to GWT? (instead of making a (redundant) asynchronous
call for the data immediately when the app first loads)
You can pass data into your gwt app as js variables, form,maybe hidden
variables, url parameters, and so on.
2) I would like to use GWT with a JSON capable server (php, django
etc). My question is, what is the best way to use GWT? Should i use
GWT to code the entire website? Should i use a single GWT app to deal
with the entire site or do i break small pieces of functionality to
small GWTapps? Or the other extreme: just use GWT to implement tiny JS
widgets combined with a traditional template rendering oriented
website (eg php). What is the common usage model?
It as a matter of tasta, and advance in gwt, and the borders of your
application:)
At firs try to make same finctional widgets, and go on.
3) WRT #2: How would you recommend implementing user login and
registration functionality using GWT+JSON?
a) Using GWT as an AJAX widget to spice up a php/django form
b) Implement a GWT app specific to registering / login users,
leaving other website functionality to other GWT apps
c) Implement user functionality using GWT into a single app
containing the entire website functionality.
I think (a.) will good for you, and will be fun.
