gistlib - a multiple attribute data filter pattern in reactjs in javascript

To implement a multiple attribute data filter pattern in ReactJS, we can follow the following steps:

Create a state object that holds the filter values, and initialize it to an empty object:


index.tsx
import React, { useState } from "react";

function MyComponent() {
  const [filters, setFilters] = useState({});
  // ...
}

Create a function that updates the filter state object when a filter value changes:


index.tsx
function handleFilterChange(attribute, value) {
  setFilters((prevFilters) => ({
    ...prevFilters,
    [attribute]: value,
  }));
}

Filter the data array based on the filter state object using the Array.filter() method:


index.tsx
const filteredData = data.filter((item) => {
  for (let key in filters) {
    if (item[key] !== filters[key]) {
      return false;
    }
  }
  return true;
});

Render the filtered data array in the component:


index.tsx
return (
  <div>
    {filteredData.map((item) => (
      // Render item
    ))}
  </div>
);

Here's an example implementation of a filterable data table using the above pattern:


index.tsx
import React, { useState } from "react";

function FilterableDataTable({ data }) {
  const [filters, setFilters] = useState({});

  function handleFilterChange(attribute, value) {
    setFilters((prevFilters) => ({
      ...prevFilters,
      [attribute]: value,
    }));
  }

  const filteredData = data.filter((item) => {
    for (let key in filters) {
      if (item[key] !== filters[key]) {
        return false;
      }
    }
    return true;
  });

  return (
    <div>
      <table>
        <thead>
          <tr>
            <th>Attribute 1</th>
            <th>Attribute 2</th>
            <th>Attribute 3</th>
          </tr>
          <tr>
            <td>
              <input
                type="text"
                onChange={(e) => handleFilterChange("attribute1", e.target.value)}
              />
            </td>
            <td>
              <select onChange={(e) => handleFilterChange("attribute2", e.target.value)}>
                <option value="">All</option>
                <option value="value1">Value 1</option>
                <option value="value2">Value 2</option>
              </select>
            </td>
            <td>
              <input
                type="number"
                onChange={(e) => handleFilterChange("attribute3", e.target.value)}
              />
            </td>
          </tr>
        </thead>
        <tbody>
          {filteredData.map((item) => (
            <tr key={item.id}>
              <td>{item.attribute1}</td>
              <td>{item.attribute2}</td>
              <td>{item.attribute3}</td>
            </tr>
          ))}
        </tbody>
      </table>
    </div>
  );
}

export default FilterableDataTable;
