This is the Prettier configuration that I use in most projects. I've debating on setting "semi": false but haven't pulled the trigger. What's the point of semicolons?
{
"printWidth": 200,
"tabWidth": 2,
"singleQuote": true,
"trailingComma": "es5",
"useTabs": false,
"arrowParens": "always",
"bracketSpacing": true,
"semi": true
}
