When you pass a generic component type to some React utility type like React.ElementConfig<typeof some_generic_component>, we will replace all the type parameters with their defaults or bounds. It can potentially cause downstream errors. (Example)
New Features:
Add built-in (intrisic) element names like div to JSX autocomplete
Mapped types now support operating directly over keys, like TypeScript's Pick and Omit (Example). Mapped type support is still experimental; enable experimental.mapped_type=true to try them.
Notable bug fixes:
Don't check @noflow files in "all" mode
Fixed a source of spurious errors when using refined string keys as computed properties in objects (Example)
Improved Go to Definition on export statements
Library Definitions:
Added rel as an attribute to HTMLFormElement
Added WeakRef class definition
Added ariaHidden DOM property
v0.206.0
Likely to cause new Flow errors:
React.Element will now accept a second type argument that specifies the props type. JSX will populate this type argument with actual props passed to component, instead of deriving it from the signature. The change will reveal some broken code, e.g. try-Flow example.
$Shape is deprecated, use Partial instead. Read this blog post for more.
Add a (temporary) option tuple_enhancements to gate our tuple type enhancements (labeled tuple elements, which can be optional or have variance annotations), so we can show a Flow error rather than having users just get syntax errors from various other tooling (e.g. Prettier, ESLint), until all that tooling is updated.
experimental.abstract_locations is removed. Setting this config to true improves Flow's performance. The config defaults to true since 0.139.
New Features:
Allow opaque types with string supertypes to be used as keys in a dictionary, and have that opaque type be preserved when using Object.keys.
To help people familiar with TS, error on and supply a quickfix to the Flow equivalent for the TS types: Readonly, ReadonlyArray, ReadonlyMap, ReadonlySet, NonNullable.
Notable bug fixes:
Error more consistently with [invalid-computed-prop] errors. try-Flow.
Fixed cases where uses of Partial/Required caused errors to be positioned poorly.
Misc:
To improve clarity of error messages we will display mixed instead of a generic type if that generic type has a default bound of mixed. try-Flow.
Object property type incompatibility errors will now contain additional explanations when the error only arises due to object property invariant subtyping.
v0.205.1
Fix over-eager IDE autocompletion of types after typing a space.
v0.205.0
Likely to cause new Flow errors:
Remove the flow get-imports CLI command.
Some duplicate errors with Arrays are invariantly typed explanations are now correctly removed.
New Features:
Added type-aware autocomplete in IDE for switch cases.
Added signature help to IDE for constructor calls.
Go-to-definition in the IDE can now provide multiple options if the target is defined in multiple locations (for example, in a union).
Add Required and Partial to list of utility types to autocomplete in the IDE.
