What's check-build, why I built it at Bringr/Redsmin and how we use it everyday inside our continuous integration workflow. Check-build: https://github.com/FGRibreau/check-build

1. Continous Integration of (JavaScript) projects
&
check-build philosophy

2. The story
“Let’s start with a little story...”

3. “My name is François-Guillaume Ribreau”

4. BringrCo-founder Founder
“I’m the co-founder (CTO) of Bringr and the founder (C[E|T]O) of Redsmin.
Some month back, our team grew in size.”

5. Bringr

“At Bringr & Redsmin we work a lot at creating micro-services (SOA),
so each of the new time member was given micro-services to build.”

“Since they were junior developers (sometimes interns), at each code-review I had to
explain software principles and our conventions”

7. conventions
&
principles
“... and I had to do it at every code-review, each-time.
Sometimes — it happened — I would not even respect my own conventions...”

8. When you ask developers
to follow coding conventions

9. Try to make the human out of the loop
“... so I came across this principle...”

10. Don't rely on principle,
rely on automation.
“... that I rewrote”

11. “People are fallible,
automated workflows are* not.“ — FG
“... that I rewrote (again)”

12. Solutions?
“Now let’s see what our current options are...”

13. Code-style checking
“We could use JSCS...”

14. Syntax checking
“... along with JSHint and so on...”

15. Bringr
A B FC D E G
“... but installing JSHINT/JSCS on each project is not DRY at all”

16. Documentation checking ?
D.R.Y checking ?
Security* checking ?
“But then what about other code dimension?”

“... another way was to install
JSHint/JSCS plugins on the CI,
but that’s like creating high
coupling...
Not a good idea either.”
“moreover, these plugin
configurations can’t be
versioned inside the project git
repository...”

18. Solution.
“... here is what I came up with.”

19. Check-build
Verifies that your NodeJS project follows
team conventions, is well written,
up to date and secure*...

“Check-build removes high coupling between the CI & projects
and between projects and quality tools.
Always install the latest version, we make sure check-build
will always be backward compatible”
