createArrayFilter

Description

The function takes filter value as an input and returns a filtered array

It uses the createFilter helper inside.

Usage

createArrayFilter:(
  value: {
    glue: "and" | "or",
    rules: {
      field: string,
      filter?: string,
      value?: string | number | date,
      includes?: any[],
      type?: "date"|"number"|"text"|"tuple",
    }[]
  },
  options?: {
     orNull?: boolean,
  }
): (data:any[]) => data:any[];

Parameters

• value - (required) filter settings:
• glue - (required) the logic for combining filtering rules:
  • "and" (default) - displays records that correspond to all rules at once
  • "or" - shows records that correspond to at least one of the rules
• rules - (required) an array of filtering rules. It can be an individual rule or a group of rules. Each rule object has the following parameters:
  • field - (required) the id of a field. It should be the same as the corresponding field id of the fields property.
  • filter - (optional) the filter operator available for this type
  • value - (optional) the value in the field
  • includes - (optional) an array of the included values (strings, numbers or dates).
  • type - (optional) filter type: "text" (default) | "number" | "date" | "tuple"
• options - (optional) it's applied when no rules are set; if set to true, null will be returned; if false (default), an array will be returned

Returns

A function takes an array and returns its filtered copy.

Example

This example demonstrates how to use createArrayFilter to generate a function to filter a data array.

<script>
  import { getData } from "../data";
  import { FilterBuilder, createArrayFilter } from "wx-svelte-filter";

  const { value, fields, options, data } = getData();

  let filteredData = $state([]);

  function applyFilter(value) {
      const filter = createArrayFilter(value);
      filteredData = filter(data);
  }

  // Apply initial filter
  applyFilter(value);
</script>

<FilterBuilder
    {value}
    {fields}
    {options}
    onchange={({ value }) => applyFilter(value)}
/>
