For 2-3 weeks, while I didn't change anything in prettier file, VSC started changing single quotes to double quotes, while it was always single quotes. I tried many options but it keeps changing it. Heres my .prettierrc
{
"trailingComma": "es5",
"printWidth": 200,
"semi": true,
"singleQuote": true,
"jsxSingleQuote": true,
"tabWidth": 2,
"quoteProps": "as-needed"
}
EDIT: I think, that it is a matter of .tsx files, as prettier has just option for .jsx files but still didn't find a solution.
