What is Prettier keyboard shortcut command in VS Code to format only a block of React code, not just format on file autosave?
reactjs - Prettier not working on save from within Visual Studio Code - Stack Overflow
Why does Prettier not format code in VS Code?
Those who stopped using prettier , why ?
Recently joined a agency as an Contract React developer. I was assigned a task to edit some inline Scss code.
Being a Prettier user I formatted the code, made the necessary changes and submitted a pull request.
Next day the senior developer reviewed my code and asked me to stop using Prettier and assigned me a task to change back the Scss code manually to inline Scss.
When I asked why should I not use prettier to format code. He said it's bad and time consuming and other team members started telling me a story how one time prettier wasn't working and started throwing errors.
That's why they never use it.
I wanted to say that It was showing error because you were doing something wrong.
Just because you once had an bad experience doesn't mean it's bad.
Plus they use one big single Scss file for the whole project.
When I question it too and asked them to use separate files and how it can effect the performance.
One team member answered it doesn't matter, how they don't care about the performance and I should be open minded and learn from them. The boss has 18 years of experience.
What should I learn why not to follow good practices!
ยป npm install prettier

On Mac OS for VS Code it's Option+Shift+F
In VSCode, hit CTRL + SHIFT + P, write Preferences: Open User Settings (JSON) and hit enter, it will open up your settings.json:
Make sure prettier is your default formatter:
"editor.defaultFormatter": "esbenp.prettier-vscode"
you can set it for specific languages e.g: for typescript:
"[typescript]": {
"editor.defaultFormatter": "esbenp.prettier-vscode"
},
TLDR; Settings > Prettier Require Config: false / unchecked
I tried these and it still wasn't working. I noticed that at the bottom of my VS Code my Prettier wasn't showing a checkmark next to it. Clicked on "Prettier" at the bottom of the screen and it said it was skipping the file because there was not a require config set to true.
Solution was in this thread here: Prettier extension is not working in vs code Require config set to true
- Select
File -> Preferences -> Settings(Ctrl+comma) and search formformatter - Set Prettiers as Default formatter.

If above does not work:
ctrl+shift+p > Format Document With... > Configure Default Formatter... > Prettier - Code formatter
This also work with ctrl+shift+I
If doing what @Simin Maleki mentioned does not solve it for you, there is a chance that your default formatter is not set:
File > Preferences > Settings > Search for "default formatter"
Make sure your Editor: Default Formatter field is not null but rather Prettier - Code formatter (esbenp.prettier-vscode) and that all the languages below are ticked. This fixed my issue.

Also make sure that your format on save is enabled:
