Deprecated Rules #115

Many rules are built-in now since ESLint supports es2017, etc

• babel/generator-star-spacing: Use generator-star-spacing.
• babel/object-shorthand: Use object-shorthand.
• babel/arrow-parens: Use arrow-parens.
• babel/func-params-comma-dangle: Use comma-dangle.
• babel/array-bracket-spacing: Use array-bracket-spacing.
• babel/flow-object-type: Use flowtype/object-type-delimiter.

New Feature

• #64 Add func-params-comma-dangle rule @zertosh
• babel/func-params-comma-dangle: Require or forbid trailing commas for function paramater lists. Behaves like, and takes the same options as, eslint's comma-dangle. (🛠 )
• #62 Add auto-fix for arrow-parens @lemonmade

New

• babel/flow-object-type: Require a particular separator between properties in Flow object types.
  • Use the option semicolon to require semicolons (e.g. type Foo = { bar: number; baz: string }).
  • Use the option comma to require commas (e.g. type Foo = { bar: number, baz: string }).
