# ArraySourceBase

`class` in `core` · v0.4.1

<https://docs.seedcord.org/packages/core/0.4.1/classes/array-source-base>

A source for a bounded list you can load whole. It loads the full list on every click, then slices the page via [`paginate`](/packages/core/0.4.1/functions/paginate), so the real total is known (a real last button, "Page X of Y"). Cache inside your loader if the load is expensive.

```ts
class ArraySourceBase<Item, Ctx> implements PageSourceBase<Item, Ctx>
```

## Constructors

### constructor

```ts
ArraySourceBase(
    load: (ctx: Ctx) => Promisable<readonly Item[]>,
    opts?: { perPage?: number }
)
```

Constructs a new instance of the `ArraySourceBase` class

## Methods

### page

```ts
public async page(
    ctx: Ctx,
    n: number
): Promise<PageView<Item>>
```
