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).

v7.2.0

• Added: [@​typescript-eslint/object-curly-spacing].
• Added: [react/jsx-newline].

v7.1.0

Compare Source

• Added: [unicorn/empty-brace-spaces]. Thanks to fisker Cheung (@​fisker)!

v7.0.0

Compare Source

• Changed: At least ESLint 7.0.0 is now required.

• Changed: [arrow-body-style] and [prefer-arrow-callback] are no longer turned off by default. They only need to be turned off if you use [eslint-plugin-prettier]. If you do, add "prettier/prettier" to your "extends" array to turn them off again.

  {
    "extends": ["prettier", "prettier/prettier"],
    "plugins": ["prettier"],
    "rules": {
      "prettier/prettier": "error"
    }
  }

  Alternatively, update [eslint-plugin-prettier] to version 3.2.0 or later which automatically turns off these two rules in its "plugin:prettier/recommended" config.

  The CLI helper tool only warns about these rules if you have the "prettier/prettier" rule enabled for a file.

• Changed: no-tabs is now a validatable rule. If you use it, you should enable allowIndentationTabs so that the rule works regardless of your Prettier config:

  {
    "rules": {
      "no-tabs": ["error", { "allowIndentationTabs": true }]
    }
  }

• Changed: The CLI helper tool is now called just eslint-config-prettier instead of eslint-config-prettier-check. This is so that npx eslint-config-prettier always works regardless of whether you have already installed eslint-config-prettier or not: If you have, the local installation is used; if you haven’t, npx downloads a temporary copy.

• Changed: The CLI helper tool no longer requires you to pipe the output of eslint --print-config to it. Instead, it does that automatically for you via ESLint API:s added in ESLint v7.

  Before:

  npx eslint --print-config index.js | npx eslint-config-prettier-check
  

  After:

  npx eslint-config-prettier index.js
  

• Improved: The npm package is now 75% smaller.
