I want to create a type for an array of objects. The array of objects can look like this:
const troll = [
{
a: 'something',
b: 'something else'
},
{
a: 'something',
b: 'something else'
}
];
the type i am trying to use is:
export type trollType = [{ [key: string]: string }];
Then i want to use the type like this:
const troll: trollType = [
{
a: 'something',
b: 'something else'
},
{
a: 'something',
b: 'something else'
}
];
but i get this error:
Type '[{ a: string; b: string; }, { a: string; b: string; }]' is not assignable to type 'trollType'.
Source has 2 element(s) but target allows only 1
I can do something like this:
export type trollType = [{ [key: string]: string }, { [key: string]: string }];
but lets say my array of object will have 100 objects in the array.
When setting a type for an array it should in this format any[].
So in your case
export type trollType = { [key: string]: string }[];
You can try to use the Record type for storing the object attribute definitions and create an array out of it, like in the following:
type TrollType = Record<string, string>[];
const troll: TrollType = [
{
a: 'something',
b: 'something else'
},
{
a: 'something',
b: 'something else'
}
];
