Intended outcome:
Have strict and complete type safety to help with refactoring.
Actual outcome:
The return type of computed() and observable.box() both have set() and get() methods, but the return type of computed() doesn't have a set() method so a type error is thrown at run time.
How to reproduce the issue:
const myObservableValue = observable.box(10);
const myComputedValue = computed(() => myObservableValue.get() + 1);
/**
* Uncaught:
* Error: [MobX] [ComputedValue 'ComputedValue@2'] It is not possible to assign a new value to a computed value.
* at die (/node_modules/mobx/dist/mobx.cjs.development.js:89:11)
* at ComputedValue.set (/node_modules/mobx/dist/mobx.cjs.development.js:1448:7)
*/
myComputedValue.set(12);
