MUI Props giving error: `requires between 4 and 5 type arguments`-CodePudding

I am trying to wrap a MuiAutocomplete around my own custom component and also pass in AutocompleteProps as a prop, while using typescript. Here's what I have:

type Props = {
  autoCompleteProps?: AutocompleteProps<T>
  label: string
  loading?: boolean
}

const AutoComplete: React.FC<Props> = ({
  autoCompleteProps,
  label,
  loading,
}) => {
  return (
    <MuiAutocomplete {...autoCompleteProps}/>
  )
}

But I get the following error on: autoCompleteProps?: AutocompleteProps<T>

Generic type 'AutocompleteProps<T, Multiple, DisableClearable, FreeSolo, ChipComponent>' requires between 4 and 5 type arguments

What am I doing wrong and how can I fix it?

And I also want to make renderInput optional

CodePudding user response：

AutocompleteProps has five generic value and one has default value, others required.

export interface CustomAutoCompleteProps<T> {
    props: AutocompleteProps<T, boolean | undefined, boolean | undefined, boolean | undefined>;
    label: string;
    loading?: boolean;
}

Component:

export const CustomAutoComplete = <T,>(props: CustomAutoCompleteProps<T>) => {
  const { label, autocompleteProps, loading } = props;

  return <Autocomplete {...autocompleteProps} />;
};

And I also want to make renderInput optional

that's not possible, renderInput and options are required field.

interface IOptions {
  label: string;
  year: number;
}

export const AutoCompleteTest = () => {
  let options: CustomAutoCompleteProps<IOptions> = {
    label: "test",
    loading: false,
    props: {
      options: [
        { label: "test", year: 2021 },
        { label: "asd", year: 2222 },
      ],
      renderInput: (params) => <TextField {...params} label={"label"} />,
    },
  };
  return <CustomAutoComplete {...options} />;
};

CodePudding user response：

As TypeScript says, AutocompleteProps needs to have 4 to 5 type arguments as it's defined like the following:

export interface AutocompleteProps<
  T,
  Multiple extends boolean | undefined,
  DisableClearable extends boolean | undefined,
  FreeSolo extends boolean | undefined,
  ChipComponent extends React.ElementType = ChipTypeMap['defaultComponent'],
> {
  // ..
}

ChipComponent has a default value that's why this props require 5 or 4 arguments.

For the others you will need to specify which type to use.

So what you can do is add some generics value to Props and simply pass them to the AutocompleteProps one:

type Props<
  T,
  Multiple extends boolean | undefined = undefined,
  DisableClearable extends boolean | undefined = undefined,
  FreeSolo extends boolean | undefined = undefined
> = {
  autoCompleteProps?: AutocompleteProps<
    T,
    Multiple,
    DisableClearable,
    FreeSolo
  >;
  label: string;
  loading?: boolean;
};

If you don't care about them in your custom API you can use simple default values:

type Props<T> = {
  autoCompleteProps?: AutocompleteProps<T, undefined, undefined, undefined>;
  label: string;
  loading?: boolean;
};
