kontextR prettier2eslint plugin

How to use it

You will need to install prettier-eslint and preconfigure both using the @ktxtr/eslint-config package.

Include this rule in your eslint configuration with:

plugins: [
  "@ktxtr/prettier"
],
rules: {
  "@ktxtr/prettier/{rule}": ...
}

Available rules

no-long-implicit-arrow

You might want to write an arrow function which looks like this:

const sayHello = () => console.log("hello!")

This is fine as long as the function is short enough. If it is too long though it becomes difficult to read:

const sayLongHello = (name = 'Mr. Incognito') => console.log(`This is just a test method. \n Hi${name}! That's all buddy!`);

This rule will break the method arguments into their own line, if it figures it will reduce the line length under the specified limit.

const sayLongHello = (name = 'Mr. Incognito') => console.log(
  `This is just a test method. \n Hi${name}! That's all buddy!`
);

You can use it with:

  "rules": {
    "@ktxtr/prettier/no-long-implicit-arrow": [{severity}, {max-arrow-line-length}]
  } 

It also accepts general settings:

settings: {
  maxLength: {max-arrow-line-length}
}

This rules ensures consistency between prettier's arrow function formatting and eslint's implicit-arrow-line-break.
