50. MY PERSONAL ITCH
Back in 2014 my itch was NodeJS and the JavaScript ecosystem
that took the web by storm

51. Everyone was talking about being MEAN

53. What does it mean to be

58. MongoDB - NoSQL Database
Document Storage

60. ExpressJS – web application framework
Ties the middleware,
Takes care of HTTP

62. AngularJS - Client-side frontend framework
MV* Architecture from Google home-base
Testable, data bindings, reusable components

64. ~2009 NodeJS – Server-side multi-purpose JavaScript platform
with async nature
Web Servers, Command Line Tools
SMTP Servers, Control an Arduino board

65. THE BENEFITS

66. THE BENEFITS

67. THE BENEFITS
Shared ecosystem

68. Too good to be true?

71. with the JavaScript EcosystemChallenges

72. legacy web development sauce not working anymore

73. CHALLENGE
How do you tie all of these JavaScript components to work
together?

74. CHALLENGE
The JavaScript ecosystem is a messy place

79. http://www.nodeframeworks.com

80. What about the tooling ecosystem?

82. Build tools:
Lint your code
Compile your SASS to CSS
Minimize your CSS and JS assets
Optimize your static image assets
Run your tests
Unit tests, integration tests, E2E tests
Nock, jshint, nodemon, livereload
Manage your package dependencies, and their security status

83. Back in 2014 - MEAN.io was the trend for a FullStack JavaScript
framework

84. Getting involved is the best way to learn!

87. "Two roads diverged in a wood, and I —I took the one less traveled
by, And that has made all the difference"

89. Why I love MEAN.JS?

90. I love it so much
that I became the lead maintainer for the project

91. I love it so much
that I started using it at work
hackathons
dashboards
small projects

92. freeboard

93. an opportunity

96. 5 years old LAMP stack

97. 5 years in software
is like
700 Chewbacca years

98. key strategic technology decisions:
Build on existing expertise
Consolidating our platform to Java & JavaScript
Micro-services architecture
