Release Notes

prettier/eslint-config-prettier

v8.1.0

Compare Source

• Added: [flowtype/object-type-curly-spacing].
• Added: Dummy files for the configs removed in 8.0.0. The dummy files throw an error that try to guide you how to upgrade.

v8.0.0

Compare Source

• Changed: All configs have been merged into one!

  To upgrade, change:

  {
    "extends": [
      "some-other-config-you-use",
      "prettier",
      "prettier/@​typescript-eslint",
      "prettier/babel",
      "prettier/flowtype",
      "prettier/react",
      "prettier/standard",
      "prettier/unicorn",
      "prettier/vue"
    ]
  }

  Into:

  {
    "extends": [
      "some-other-config-you-use",
      "prettier"
    ]
  }

  The "prettier" config now includes not just ESLint core rules, but also rules from all plugins. Much simpler!

  So … what’s the catch? Why haven’t we done this earlier? Turns out it’s just a sad mistake. I (@​lydell) was confused when testing, and thought that turning off unknown rules in a config was an error. Thanks to Georgii Dolzhykov (@​thorn0) for pointing this out!

  If you use [eslint-plugin-prettier], all you need is [plugin:prettier/recommended]:

  {
    "extends": [
      "some-other-config-you-use",
      "plugin:prettier/recommended"
    ]
  }

  (The ["prettier/prettier" config][prettier-prettier-config] still exists separately. It’s the odd one out. The main "prettier" config does not include the rules from it.)

• Changed: The CLI helper tool now only prints warnings for [arrow-body-style] and [prefer-arrow-callback], just like other “special rules.” This means that if you’ve decided to use those rules and [eslint-plugin-prettier] at the same time, you’ll get warnings but exit code zero (success).
