Pragmatic Web (no) Frameworks Tools Patterns 3 Practices

Get the Control back! Less Pain 4

Background Should I really care? 5

6

Complexity is everywhere and making things simple is hard! 7

-1- 8

The Domain Problem 9

10 humans need to talk more

Wrong models cause massive accidental complexity Greg Young 11

Customer needs Foo 12

You think schema Bar 13

Dont think schema too hard 14

There is no good but some of them are useful 15 { Model | Architecture | persistance }

maybe partially maybe aggregated but surely in an unique context 16

17

-2- 18

Over Engineered ? 19 The Architecture Problem

you MUST decouple your ugly monolithic app in LAYERS 20 (evil said)

21

22 arg

Hexagonal, Onion? 23 Yes!

24

Concrete Application? 25

((You/Me/Them) misunderstood Fail 26

27 Architecture is about an intent, its not about a technical framework

28 Architecture is the art of taking decisions lately

29 Templates, patterns, scaolding dont solve anything they are just tools to start faster

30 Avoid dependencies Use abstractions Use right naming

31

-3- 32

33 what about design?

34 Are You Simple enough?

Solving the wrong problem - it may happened - 35

36 It should go faster !

37 Lets take a more modern engine!

all that matters! Bad Understanding Poor design No design Bad technology locking 38 } Generates Complexity !

-4- 39

please, help 40 What about tools?

1-1 Frameworks? 41 And Libraries

Frameworks? 42

Frameworks ? 43

A framework >> it calls you 44

45 YOU Call a Library

OSS ? oss projects -most of the time- fit real user needs tiny oss libraries usually t one need, but do it well. 46

1 11 Get the shell back! 47

Curl Everything you need to test your app is here! -X [GET|POST] -I (include headers) -d key=value 48

Nuget Package management is essenPal Enterprise grade => build your own Quite mulP-plaTorm 49

Nuget curl hUp://nuget.org/nuget.exe -L -k -o nuget.exe #!/bin/sh PATH=/usr/local/bin:$PATH mono --run1me=v4.0 /usr/local/bin/NuGet.exe $* (for Mac lovers) 50

Chocolatey @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('http://bit.ly/ psChocInstall'))" && SET PATH=%PATH%;%systemdrive% chocolateybin (nuget powered) > Cinst ruby 51

Nano just enough editing capabilities in the shell > Cinst nano 52

Gulp/Fake/Bau Simple taks based build tools, on your language! 53

54

55 1 12 See it live! If you dont see it live, then it may be dead

56

Glimpse Firebug for asp.net 57

Chrome dev tools 58

Editors Chose a good tool also for the client side! Webstorm 59

Online web editors C9.io Jsddle.com Jsbin.net Plnkr.co Codepen.io 60

61 1 33 Efficient Libs Do More for Less

jQuery 62

jQuery 63

Angular Html enhanced for web apps! 64

Angular Dependency Injection TESTS TDD Mocks MVC Two-way Data-binding Templates more than that! 65

66

Less css dotLess for .Net 67

68 1 4 Polyglot over patterns and other convention over configuration beauties

Be PolyGlot! 69

Nancy fx 70

Install PM> Install-Package Nancy ! ! Write public class SampleModule : Nancy.NancyModule { public SampleModule() { Get["/"] = _ => "Hello World!"; } } ! ! ! Go! 71

ORM Light || MASSIVE || DAPPER 72

SignalR (Socket.io like framework for .Net) 73

So what? 74

75 Simplicity?

What problem are trying to solve? Always! 76

Avoid coupling everywhere, from classes to libraries 77

Be Consistent Readability, Rules, Conventions 78

if you dont love it, it gonna fail! stay foolish, stay hungry Jobs 79

Get more Fun 80
