Presentation about large scale applications based in Javascript language. Concepts that I've being studying and recommending.

1. JS Based
Applications
by Marcelo Henrique (bissuh)

2. Where we are?
- Dynamic applications: adaptable and fast
versioning
- Onion applications: each day a new layer
is added
- Large-scale applications: non-trivial
application where most data manipulation is
in browser

3. Advantages
- Relationships between developers
becomes more clear
- Portable applications

4. Does it worth?
Maybe
¯_(ツ)_/¯

5. Does it worth?
Only where those advantages here
listed makes sense

6. Brainstorming Area

7. Important concepts
Module pattern
Facade pattern
Mediator pattern

8. What we want?
Independent, ready to use
and re-usable features

9. Module pattern
- Allow private/public objects
- Methods are named and easy to
find in stack
- Clear for developers coming from
object-oriented background

10. Module pattern
- Allow private/public objects
- Methods are named and easy to
find in stack
- Clear for developers coming from
object-oriented background

11. Module pattern
Problem: public and private members
are accessed in diferent ways.
It requires a lot of work when
changing visibility.

12. Module pattern
Problem: inability to create unit tests
for private members.
Problem: private members are not
this flexible.

13. Facade pattern
- Encapsulate modules and objects
- Keep it easy to change technologies
or use the same function in different
environments

14. Facade pattern
- Problem: performance
- Sometimes it worth, sometimes not.
Study your case.

15. Mediator pattern
- Helps to solve modules
interdependency
- Creates an easy model to add
features

16. - Problem: performance
Mediator pattern
