Lesson 5: Quick tip about .env + Prettier

[pyromaus]

I was at the point where Patrick transfers the private key from deploy.js into its own .env file.

Then upon running deploy.js I got an invalid hexlify value error and it tells me my private key value is: f3361523778699819320ab3b519f47a6b7b2ee324bb5c9b8e4091ca23e221cc7;

Prettier is automatically adding a semi-colon to the private key, which doesn't belong. When you remove it, Prettier adds it back upon save. Then I noticed from Patrick's screen he has Prettier disabled while editing .env

After a quick google, my .env looks something like this

// prettier-ignore
PRIVATE_KEY = f336..........etc........cc7

After this change, deploy.js ran with no problems

Alternatively you can tell Prettier to ignore certain file extensions.

In your project folder make a file named .prettierignore then write

*.env

This will get Prettier to skip formatting all files with that extension (only in your project folder)

@pyromaus I think this will only happen when you have Prettier as the default Formatter for all files. But as Patric shows in his video to sets a formater for solidity, javascript, etc. This way .env file will never be formatted automatically until you set Prettier for it also.

@ali-thegilfoyle Lol the weird part is my Default Formatter in VScode is set to none and my settings.json is exactly like Patrick does in his video. Must be another setting I am not seeing.

As a 3rd option you can stop Prettier by going to Command Palette and doing
Save without Formatting
(unless you have Auto Save onFocusChange)
