Improve type inferrence of data type rules
See original GitHub issueThe idea came from the discussion. Currently, ON returns string: 'on';
infers
export type ON = string;
Instead, we could infer it like
export type ON = 'on'

Okay, adding enums is not what we want. However, I’d anyway expect that
MyEnum returns string: 'on'
would generate a typeon
forMyEnum
and not just a string. It’s like a enum with the only one element, and if forMyEnum returns string: 'on' | 'off'
we generate a type'on' | 'off'
, why not do the same for the only one type alternative?@dhuebner, yes, I like this idea. For example, this
will generate
So, addition a keyword
enum
restricts to use only data type rules in a union, and we can infer type like a union of these data type rules without tries to evaluate a pattern.
