Create .prettierrc

[pushkine]

This file is used in case you have the prettier extension installed and you format the file you're working on

I'm not asking to reformat the whole thing, or to have those options precisely, I just want a preset common to the project, so as to make it consistent looking

The options as is are compatible with the linting, I'd like the semi linting rule removed however, doesn't make much sense to keep it enabled
one-var also, but that might be more touchy I guess

This was specifically removed a couple of months ago - see #4378.

So the problem was that it breaks lines in long template literals ?
Why not increase printWidth instead of removing formatting from the whole project ?

I think that this file should follow the defaults from the official options found here - https://prettier.io/docs/en/options.html with the exception of adding "useTabs": true and "tabWidth": 4 The Prettier - Code formatter extension does not follow them and thus they should be inserted from a file. I personally use a .prettierrc file with the following inside, however I keep it in a parent directory, in order not to produce opinionated repositories:

{
	"arrowParens": "always",
	"bracketSpacing": true,
	"endOfLine": "lf",
	"htmlWhitespaceSensitivity": "css",
	"insertPragma": false,
	"jsxBracketSameLine": false,
	"jsxSingleQuote": false,
	"printWidth": 80,
	"proseWrap": "preserve",
	"quoteProps": "as-needed",
	"requirePragma": false,
	"semi": true,
	"singleQuote": false,
	"svelteAllowShorthand": true,
	"svelteBracketNewLine": true,
	"svelteSortOrder": "scripts-styles-markup",
	"svelteStrictMode": true,
	"tabWidth": 4,
	"trailingComma": "es5",
	"useTabs": true,
	"vueIndentScriptAndStyle": false
}

None of the core maintainers are going to be using Prettier when editing the code, probably. The ESLint rules provide adequate, and less opinionated, formatting guidance. We don't want to have an 'optional' prettierrc file, and we don't want people submitting PRs that change 8,000 extra lines because they did happen see the prettierrc file and use Prettier. Ultimately this comes down to maintainer preference, and as a whole the maintainers prefer ESLint alone over ESLint + Prettier.
