being built?

11. How about the
backend?

12. Hmm, anyone
knows Java?
Ruby on Rails?
Django?

13. Don't let the backend be
an after thought!

14. Developing the backend of
a mobile App
from scratch is rarely a
good option

15. Do you really want to
implement user
management once again?

16. How about...
?
File storage
Localized content
Social Meta-Data
Search
Relationships
Authentication
Workflow
Comments
Tagging
Categorization

17. Liferay offers many
reusable services for
building Apps

Reusable Services
Identity
User Management
Permissions
Content Management
Document Management
Dynamic Forms
...

18. Some of you are already doing this
Forums App Blog reader Blogs, Agenda, Content

19. But it requires knowing Liferay
really well...
Right?

20. Liferay Screens
Create Native Apps
backed by Liferay in a
fraction of the time
Screen UI
Screen Local

21. How long does it take
to build an App?
(Including the backend)

22. How about 1 minute?

23. Characteristics
✓Fully functional
Screenlets backed by a
Liferay server
✓100% themable
✓Compatible with iOS/
Android SDKs
✓Open Source

platform than ever
before

29. Much better browsers....
... for desktop & mobile

30. The JavaScript revolution
New Standards, Frameworks and techniques
SPA

31. New frontend development workflow
Multi-browser test automation
Resource Optimization
Fast dev environment (watch)
Zeno

32. How can we leverage this
within Liferay?

33. Think beyond Portlets...

34. Portlets are great.... as widgets
Site Admin
✓ I can add portlets
whenever I want
Frontend Developer
x So many limitations

35. Full Page Apps within a Liferay Site
I own the
page!
I'm free!

36. Standalone Apps backed by Liferay

37. Independent Web Apps leveraging Liferay
Angular JS Application
Intranet for persons with disabilities

38. Supporting Standalone Apps
Liferay Core JS
Remote APIs
HTTP 2.0
Web Sockets
Reusable services
SSO • Theming • Permissions
Local
APIs
Native mobile OS UI
Mobile Device
Wearable, IoT
Native App
Mobile SDK Client
Eduardo

39. And developers got all the freedom
back :)

40. To use any frontend tool
v4 to be based on jQuery
Web
Components

41. "Real Time" Applications
Server Push & Async Requests
Updates
+ Servlet 3.1
Igor Iliyan

42. These new ways of
leveraging Liferay
demand an even
better platform

43. Fine grained
Modularity and
Extensibility

44. Goal 1
Use just the pieces of
Liferay you really need

45. Maintainable & Scalable
Breaking down
the monolith
Author: Mike Richard / Source: vagabondish.com

46. Modular Platform
Breaking the platform and reusable services into
OSGi modules yields many benefits
F Only deploy needed modules.
B Uses standard OSGi extension points.
New!
A Dependencies are declared.
Scale indiv. C modules separately.
D True hot deployment.
Blogs
μ μ
μ μ E μservices

47. Dependency Management
MANIFEST
Import-Package:
com.liferay.polls,
com.liferay.blogs,
com.liferay.users
Export-Package:
com.liferay.messageboards
Can be autogenerated with bnd
Fixes the class loading hell in a very elegant way
Miguel
Ray

48. Goal 2
Extensibility built to last

49. OSGi Extensions
Instead of
auto.login.hooks=com.liferay.samples.MyAutoLogin
Use an annotation
@Component
public class MyAutoLogin implements AutoLogin {
...
}
Using OSGi Declarative Services

50. Make any custom class
extensible
@Component
public class MyMenuClass {
...
@Reference
public void setMenuRenderer(MenuRenderer mr) {
_menuRenderer = mr;
}
}
Using OSGi Declarative Services

51. Make any custom class
extensible
@Component
public class MyMenuClass {
...
@Reference(
cardinality = ReferenceCardinality.MULTIPLE,
policy = ReferencePolicy.DYNAMIC,
...
)
public void addMenuItem(MenuItem mi) {
_menuItems.add(mi);
}
}
Using OSGi Declarative Services

52. @Component
public class MyMenuItem implements MenuItem {
...
}
Make any custom class
extensible

53. Audience Targeting
A great example
1 App
made of
30+
modules
Highly
Extensible
Julio Eduardo Eudaldo

54. Better ways to develop
UI Extensions
Granularity + Maintainability
No more need for
JSP overrides!
Carlos

55. Big focus on APIs and
efficient protocols

56. Semantic Versioning
Version each module independently
Standard to differentiate breaking
changes
Automatic compatibility checks
semver.org
✓Dependencies on
specific modules and
versions, not a big
Liferay version

57. Goal 3
Work less, do more

58. Autogenerated conf UI
Strongly Typed
You can even define custom
types

59. Autogenerated conf UI

60. Autogenerated conf UI
1. Injected in your service
@Activate
protected void activate(AmazonRankingsConfiguration conf) {
String rankingsId = conf.amazonRankingsId();
...
}
2. Fully dynamic
Change the configuration at any time
Draft API
Ray

61. State of the art dev tooling
Embrace and contribute to best of breed applications
instead of building our own
+

62. It's a exciting time to be a
Liferay Developer

63. You can reuse your
knowledge to do
more than ever before

64. Mobile Apps/IoT
Native, Hybrid, Web, ...
Amazing sites & portals
Which keep getting better
Innovative Web Apps
With any technology
Liferay Platform
More modular and extensible

65. The Liferay Way
Open Source
Following Standards
Using state-of-the-art tools

66. Don't stand still while so
many new things are
happening

67. Get involved early
Develop Apps with Screens
Use the new dev tools
Try out the Liferay 7 milestones

68. Look for these guys!
