QUESTION
I'm slowly starting to learn TS and implement it to current project however I stuck and don't really understand what is wrong. Basically I have button which has dataset "mode". After clicking on button I launch confirm bar (confirm bar is not TSX yet)
...ANSWER
Answered 2021-May-12 at 08:01This waring
is because you are reusing Event
object.
You passed it here ConfirmBar('You sure?', supportCommands, e)
And you reused it here action(parameter);
I don't know what do you need from paramenter
but I guess it could be like this:

I'm trying to use span
to allow the events using grid-column
to spread across multiple days in a calendar, but this seems to only work in css or styled-components. It does not work in inline-styles. Anyone have any idea to make this work with inline-styles?

QUESTION
I'm trying to write a function that returns another function that lets me modify the keys of an object in TypeScript. This is for use within a React reducer.
If I have a state object with keys dogs
, dogIds
, and another state object with keys cats
and catIds
, I'd like to write a patchGroup(group: string)
so that if I pass in cat
or dog
, it returns a function that lets me modify those keys.
I'm new to TypeScript, so I tried indexing with strings. However, TypeScript errors out because I can't use strings to index my other types
...
For example, I define the following state for dogs:
...ANSWER
Answered 2020-Apr-21 at 16:27The main issue with expecting TypeScript to verify type safety in your scenario is that TypeScript currently does not have a way to concatenate string literal types. See microsoft/TypeScript#12940 for discussion about this, and microsoft/TypeScript#12754 for a suggestion that, if implemented, would allow this. So while the compiler understands that "cat"
is a literal string type and can distinguish it from "dog"
, it has no way to know that the "cat"+"Id"
will result in the string literal type "catId"
. It only knows that "cat"+"Id"
is of the type string
.
And so it doesn't know what to do when you index into a Cat
with "cat"+"Id"
. It can't index into a Cat
with a generic string
due to the lack of string index signature.
So it depends what your goal here is. If your goal is just to suppress the errors and not worry about the compiler verifying safety, then you can start using type assertions like this:

QUESTION
What are the types of React.js's state and event?
In my code below, I can only make it work by using type: any
but it's just a hack. How can I use the right types for them?
In my custom hooks:
If I use function useFormFields(initialState: object)
, I get:
ANSWER
Answered 2020-Feb-09 at 14:46Since every component may be different you need to define the state and props types by yourself. There are some basic types defined for react (because every component may have children
for example) but as i said, you will need to define your own types.
An example for a functional component:
QUESTION
I don't understand, how the input color type works.
I am trying to have a color picker and put the value into a state variable "color".
...ANSWER
Answered 2020-Jan-27 at 22:40The onChange
event handler receives an event object as parameter.
This event object contains the selected color as event.target.value
, just like a regular text input would.
With this in mind, the following will allow you to hold on to the selected color:

Answered 2019-Oct-18 at 05:31That's because typeof x.a
is actually a string. Here, x is constant but the value of x.a
can be changed to any string value.
If the value of x.a
is not going to change then a possible solution(using const assertion added in typescript version 3.4):
QUESTION
I am using the react-event-timeline lib (here: https://www.npmjs.com/package/react-event-timeline) to create a timeline for one of my pages.
I create a list of events called: events and pass it to the timeline. The timeline consists of two parts the first is the initial event, when the page is created there is a timeline event at the top of each timeline to catch that. The second part is dynamically generated based on the list of events provided by the state of the page.
React throws this timeline error and based on debugging I think the issue is with the structure of the html below where The && checks are:
The error I get is:
React.cloneElement(...): The argument must be a React element, but you passed null.
The above error occurred in the component: in Timeline (created by TimelineComponent)
