Package Exports

react-redux-typescript

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-redux-typescript) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Mapped Types

Diff

// TestDiff expects: ('a' | 'b')
type TestDiff = Diff<'a' | 'b' | 'c', 'c' | 'd'>;

Omit

// TestOmit expects: { b: number, c: boolean }
type TestOmit = Omit<{ a: string, b: number, c: boolean }, 'a'>;

Overwrite

// TestOverwrite expects: { b: number, c: boolean } & { a: number }
type TestOverwrite = Overwrite<{ a: string, b: number, c: boolean }, { a: number }>;

getReturnOfExpression

Get return value of an "expression" with inferred return type
alias: returntypeof
https://github.com/Microsoft/TypeScript/issues/6606

// this polyfill exist because TypeScript does not support getting type of expression 
// (tracking issue: https://github.com/Microsoft/TypeScript/issues/6606)
export function getReturnOfExpression<RT>(
  expression: (...params: any[]) => RT,
): RT {
  return null as any as RT;
}

// Example:
import { getReturnOfExpression } from 'react-redux-typescript';

const increment = () => ({ type: 'INCREMENT' as 'INCREMENT' });

const returnOfIncrement = getReturnOfExpression(increment);
type INCREMENT = typeof returnOfIncrement; // { type: "INCREMENT"; }
