After years of typing "npm run [script]", by habit, I just happened to stumble on this in vs code. Hover over the script name and click run. (I know, probably nothing new to everyone, but new to me :))

 

I think you can also add scripts to the sidebar in VS Code, which lists the scripts and lets you run them from there.

 

That's really cool too! I don't know how I missed that!

 
 

How to use lenses in f# to drasticaly simplify updating nested records

 

Which library did you use, aether?

 

I use fsharpplus because the aether website was down when I decided to try lenses:)

 

Sounds like it would make for a great post on DEV and/or your blog!

 

Never wrote a blog before but i might try

 

This week, I learned to rely on shopify apps the hard way. The client I work with lessened the hours on my timedoctor due to an unjustifiable amount of time implementing a requested feature rather than going through the apps on the app store.

 
 

This week, I learnt that you can stash one file instead of all files. I figured it was possible, but never really had a need to do it until this week.

git stash push -- path/to/your/file/your-file.extension
 

Interesting. The other day I learned that you can checkout a single file from another branch to the current branch you're working on.

 

Oh, man - third week of JS class, and since it's all new to me, the list of what I learned this week would take up too much space! :) Probably the most useful thing I learned this week was how arrays sort elements by converting them to strings then comparing their UTF-16 code unit values.

 

I learned how to use PHP Storm and OMG it's amazing!

 

I learned Jest! I feel safer now

 

I learned how to use RabbitMQ as the communications layer for my microservices.

 

This week I learned enough of the pygame python library to be dangerous. I am pretty excited to start making silly games again!

 

I learn manage server using moss.sh
