Unreleased

11.0.1

Fixed

• Enable function expressions again (#258)
  • We didn't realize this rule would disallow class methods, even class constructors. This was too disruptive.

11.0.0

Added

• BREAKING: Enable id-denylist and id-length in base config (#200)
• BREAKING: Add rules for hybrid Node.js and browser environments (#242)
  • The base config now only allows globals and modules that are available in both Node.js and browsers.
  • This adds a new @metamask/eslint-config-browser package, to be used in browser-only environments.
  • The @metamask/eslint-config-nodejs package has been updated to allow Node.js-only globals and modules.

Changed

• BREAKING: Remove no-undef in favour of custom environments configuration (#254)
• BREAKING: Bump all ESLint dependencies to the latest version (#252)
  • This includes peer dependencies.
• BREAKING: Automatically sort imports (#248)
• BREAKING: Disable more undesired syntax (#207)
  • This disables the with statement, function expressions, and the in operator.

10.0.0

Changed

• BREAKING: Update ESLint from v7 to v8 (#233)
  • This is breaking because eslint is a peerDependency.
  • Four new rules have been added:
    • no-loss-of-precision
    • no-nonoctal-decimal-escape
    • no-unsafe-optional-chaining
    • no-useless-backreference
• BREAKING: Update eslint-plugin-prettier from v3 to v4 (#231)
  • This is breaking beacuse eslint-plugin-prettier is a peerDependency.
• BREAKING: Update minimium Node.js version to v14 (#225)
• Ignore rest siblings for no-unused-vars (#213)
  • This makes the no-unused-vars rule more permissive

9.0.0

Added

• BREAKING: Add JSDoc ESLint rules (#203)

8.0.0

Changed

• BREAKING: Require newlines between multiline blocks and expressions (#197)

7.0.1

Fixed

• Restore default parserOptions (#193)
  • By extending the recommended eslint-plugin-import rules, we accidentally changed the default parserOptions.sourceType to module. The sourceType is now explicitly set to script.
  • In some cases, parserOptions.ecmaVersion could also be set to an incorrect version. The ecmaVersion is now explicitly set to 2017, matching the corresponding setting in env.

7.0.0

Changed

• BREAKING: Update Prettier quoteProps rule to as-needed (#181)
• BREAKING: Update ESLint no-shadow config (#168)
• Use recommended eslint-plugin-import rule sets (#184)
  • This only removed or disabled rules, and is not breaking.
• Update install instructions in readme (#185)
• Normalize rule config values (#169)

Changed

• BREAKING: Set minimum Node.js version to ^12.0.0 (#144)
• BREAKING: Set ECMAScript version to es2017/8 (#150)
• BREAKING: Add the Prettier ESLint plugin and extend the recommended Prettier ESLint config (#96)
  • See here for the eslint-plugin-prettier rules and here for the rules of eslint-config-prettier, which the plugin extends.
  • The rules of this config should otherwise be unchanged.
• Update eslint and other ESLint peer dependencies (#151)

Removed

• BREAKING: All configs except the base config (#141)
  • All configs are now published as separate packages, and must be extended by referencing their package names:
    • @metamask/eslint-config (the base config)
    • @metamask/eslint-config-jest
    • @metamask/eslint-config-mocha
