react-query-filter

Heads up: This is still a work in progress. A lot of breaking change might happen and a lot of features are still missing. PR's are very welcome but please open an issue first describing what you think could be better.

Set of utilities to implement a Query Builder for filters.

This library ships a useQueryFilters hook that you can use to implement an UI on top of it.

The useQueryFilters will track state changes and enable you to build your own UI implementation on top of it.

Usage

Code speaks for itself, so here is an example implementing a FilterSelection and FilterRow components using useQueryFilters and chakra-ui.

First, make sure you have the following dependencies in place:

# install chakra and dependencies
yarn add @chakra-ui/react @emotion/react @emotion/styled framer-motion

# install react-query-filter
yarn add react-query-filter

/** FilterSelection.tsx */
import React, { FC } from 'react';
import {
  Button,
  HStack,
  SimpleGrid,
  SlideFade,
  Code,
} from '@chakra-ui/react';
import { useQueryFilters, Filter, PropertyDescription } from 'react-query-filter';
import { FilterRow } from './FilterRow';

interface Props {
  value?: Filter[];
  onChange?: (filters: Filter[]) => void;
  properties: PropertyDescription[];
}

export const FilterSelection: FC<Props> = ({ properties }) => {
  const { filters, onAddFilter, createFilterRowProps } = useQueryFilters({
    properties
  });

  return (
    <SimpleGrid columns={1} spacingY={4}>
      <SimpleGrid columns={1} spacingY={3}>
        {filters.map((_filter, index) => (
          <SlideFade in={true} key={index}>
            <FilterRow {...createFilterRowProps(index)} />
          </SlideFade>
        ))}
      </SimpleGrid>

      <HStack>
        <Button size="sm" onClick={onAddFilter}>
          Add filter
        </Button>
      </HStack>

      <Code padding={4}>
        <pre>{JSON.stringify(filters, null, 2)}</pre>
      </Code>
    </SimpleGrid>
  );
};

/** FilterRow.tsx */
import React from 'react';
import {
  CloseButton,
  Text,
  HStack,
  Input,
  Select,
  Tooltip,
} from '@chakra-ui/react';
import { FilterRowProps } from 'react-query-filter';

export const FilterRow: React.FC<FilterRowProps> = ({
  filter,
  fields,
  bindings,
  operations,
  shouldRenderBindingSelect,
  shouldRenderValueInput,
  onRemove,
  onChangeBinding,
  onChangeField,
  onChangeOperation,
  onChangeValue,
}) => (
  <HStack>
    <Tooltip shouldWrapChildren label="Remove Filter" placement="left">
      <CloseButton onClick={onRemove} />
    </Tooltip>

    {shouldRenderBindingSelect ? (
      <Select
        size="sm"
        maxWidth="6rem"
        value={filter.binding}
        onChange={onChangeBinding}
      >
        {bindings.map(binding => (
          <option
            value={binding.value}
            key={binding.value}
            selected={filter.binding === binding.value}
          >
            {binding.label}
          </option>
        ))}
      </Select>
    ) : (
      <Text fontSize="sm">Where&nbsp;</Text>
    )}

    <Select
      size="sm"
      value={filter.field}
      onChange={onChangeField}
      placeholder="Field"
    >
      {fields.map(field => (
        <option
          value={field.value}
          key={field.value}
          selected={filter.field === field.value}
        >
          {field.label}
        </option>
      ))}
    </Select>

    <Select
      size="sm"
      value={filter.operation}
      onChange={onChangeOperation}
      placeholder="Operation"
    >
      {operations.map(operation => (
        <option
          value={operation.value}
          key={operation.value}
          selected={filter.operation === operation.value}
        >
          {operation.label}
        </option>
      ))}
    </Select>

    {shouldRenderValueInput && (
      <Input
        size="sm"
        placeholder="Value"
        value={filter.value ?? ''}
        onChange={onChangeValue}
      />
    )}
  </HStack>
);

This component can then be used like this:

const properties: PropertyDescription[] = [
  {
    label: 'Name',
    key: 'name',
    type: 'string',
    suggestions: ['Artemis', 'Apollo', 'Donna', 'Dhio'],
  },
  {
    label: 'Age',
    key: 'age',
    type: 'number',
    suggestions: [1, 2, 3],
  },
  {
    label: 'Has Owner',
    key: 'has_owner',
    type: 'boolean',
  },
];

<FilterSelection properties={properties} />
