1. Invitation of the
BEAR.Sunday's world.

2. What is BEAR.Sunday?
•
It is web application framework.
•
Has no components of its own.
•
Everything is a resource. BEAR doesn t have Model, View,
Controller. Only have resource.
•
It doesn't restricted a system implementation.
•
It can do inversion of control by dependency injection.
•
It does decouple each implementation by aspect oriented.

3. What is a resource?
•
Resource is pure information. It doesn't have a form.
•
The form be decided when has a URI.
•
URI like a method name for BEAR.
•
Resource has a form by URI.
•
URI is API of a resource, URI has methods that
express like a event to resource. We called this
REST.

4. $student = array(
'id' => 1,
'name' => 'John'
);
GET /DB/User/Student
DB_User_Student::onRead()
Database: users table
How to extract the modelized data from
a resource.

5. What is a dependency injection?
•
DI remove dependency of each
implementation.
•
Intent will be decouple with implementation
by DI.
•
DI give testability to a system because it
can inject a test data.

6. Yellow
Left
Hand
Human
Hand s be able to dependency inject
"human", "left", yellow".

7. What is aspect oriented?
•
Aspect is epithet of implementation, and
decouple with the true nature of the
implement.
•
Aspect can be cross-cutting on objects.

8. Object

9. Aspect_After_Log
Aspect_Around_Transaction
Aspect_Before_Auth
DB_User_Student::onRead()
Service_House::onCreate()
Analysis_Student_House::onUpdate()
Service_Student::onRead()
Concrete example.

10. Why choose BEAR.Sunday?
•
Web application must be able to respond
flexibly to changes because web service is
unstable always.
•
Simple rule is best. It's Minimalism. Minimalism
will give clarity to intent of the design.
•
The procedure method be able to consistent if
request method of web application is under
control of the URI.

11. What is AngularJS?
•
It is front-end framework.
•
It be MVVM pattern.
•
Decouple each layer by role of reproduce:
Data binding, Animation, Transition.
•
It has best captured the concept of
resource by reproduce.

12. What is reproduce?
•
The Intelligence can be found in a resource,
but cannot found in the physical world.
This is Movement of the impression . It s
like cloud's move. cloud is not moving in
practice, It reproduced to changes in
humidity and atmospheric pressure.

13. What is MVVM pattern?
•
It will be decouple View with Mode by ViewModel.
•
View pattern is representation.
•
Model pattern is resource.
•
ViewModel pattern is How to make visual from
resource . It will give Movement of the
impression from Model to View.
•
The true nature of MVVM pattern is ViewModel.

14. Resource: Sun
Behavior: Cloud
Resource: Wind, Water
MVVM pattern diagram by cloud s
move.

15. Why choose AngularJS?
•
The visual design should be reproduce
from a resource because the true nature of
data there are in a resource.
•
It will decouple behavior from visualize in
HTML. It s like a cloud s example.

16. Why mix BEAR.Sunday
and AngularJS?
•
BEAR.Sunday be able to handling a resource by URI.
•
AngularJS be able to control DOM by WebSocket.
•
These be able to control DOM by URI.
•
DOM be able to reproduce from resource according to
URI when the system be implemented by BEAR.Sunday
and AngularJS.
•
Therefore, HTTP and WebSocket request become
abstract.
