Q. How many npm module are you using?
None
197
197 = 197 decisions
Q. Can you explain a reason behind every npm module
you chose?
Let’s think! https://jp.freeimages.com/photo/thinking-1387695
http://www.modulecounts.com/
It’s like a jewelry box! Let’s choose!
Wait!! Can you explain the Goal you set?
Using a npm module is not Goal Goal is to
solve the problem
Define the Goal Think about the candidates Decide what to
use Solve the problem
Define the Goal Think about the candidates Decide what to
use Solve the problem
Define the Goal • There are still many problems to
solve • We always use some tool to solve that problem
Define the Goal Think about the candidates Decide what to
use Solve the problem
Search a npm module • www.npmjs.com • awesome-* pages •
Recommendation from other engineers • Googling
Define the Goal Think about the candidates Decide what to
use Solve the problem
Select from candidates • When you have multiple choices, you
need to compare them • There are a lot of points to do that
• Star count • API design • Size of community
• Performance • Documentation • Test coverage • Quality of code • and so on...
https://jp.freeimages.com/photo/cat-1537181
Again, the Goal is... • Let’s decide the priority by
thinking about the Goal • If you will use it for prototyping, not necessary to mind test coverage • If you will use it for only development environment, file size won’t be a problem
OK, let’s use that!
Wait!! Did you think about the cost to maintain that?
Using a npm module is not free :( • It
takes time to maintain • Managing vulnerability/version • If maintenance stops, you will need to fork it
Think about Pros/Cons everytime • We SHOULD think about Pros/Cons
everytime • What is the benefit to use that? • What is the problem to use that? • If Pros won, let’s use that!
Define the Goal Think about the candidates Decide what to
use Solve the problem
None
Q. Can you explain a reason behind every npm module
you chose?
Conclusion
Make it better! • You should be able to explain
the reason • It’ll be a good experience even if you made a wrong decision
Thank you @sota1235 JavaScript lover
