Ready-to-use-in-SPA table component

Goal of this component is provide standard and simple-to-use component to display and operate over data presented in tables. Such data are usually provided by server side using some find... methods with page and size arguments, as well as filtering, sorting and other options.

Online demo: HERE

Main features:

• [x] Display and navigate over pages of data
• [x] Change size of page
• [x] Allow actions to be executed with elements (with or without autorefresh after action completed).
• [x] Allow selecting multiple elements and execute single action over them
• [x] Server-side sorting (i.e. passing sort argument to server)
• [x] Server-side filtering (allow to display filters and pass filter arguments to server)
• [x] Integration with react-router to support fetching arguments from URL and pushing changes back
• [x] Allow user to change visibility and order of columns to be displayed
• [x] Allow to customize what to display before and after the Table: page selection, page size selection, custom text, etc.
• [ ] (TODO) Support standard renderers for date, time and other OpenAPI types

Additional small features that nice to have:

• [x] Abort fetch() request if next fetch() is called with new arguments
• [x] Ignore results from old fetch() if new one is already called
• [x] "Select all" checkbox
• [ ] (TODO) examples of custom field types with custom renderers (color)

API

Installation:

npm install --save @vlsergey/react-bootstrap-pagetable

Main component is exposed as default module export of library. There are 2 main properties to define. First is itemModel -- defines the data structure, how to display data. Second is fetch -- provides implementation of method to query data from server (or memory).

import PageTable from '@vlsergey/react-bootstrap-pagetable';

// ...
return <PageTable
         fetch={this.fetchDataImpl}
         itemModel={itemModel} />

To enable react-router integration import another variant of PageTable:

import {UncontrolledWithReactRouter as PageTable} from '@vlsergey/react-bootstrap-pagetable';

| Property | Data type | Default value | Description | | ------------------------ | ---------------------------------------------- | ------------- | ----------- | | fetch | ( fetchArgs: FetchArgs ) => Promise<Page<T>> | required | See below | | itemModel | ItemModel<T> | required | See below | | actions | Action[] | 0 | Allows to display buttons at the bottom of page table and use them to execute actions over single or multiple elements from single page of the table. | | defaultPage | number | 0 | Default page to display (0-based) | | defaultSize | number | 10 | Default page size to display | | defaultSort | string | | Default page sort. One can specify only field name like name or field name and direction like name,ASC / name,DESC. | | footerElements | (() => JSX.Element)[][][] | | Elements to be rendered by DefaultFooter before page at the left (0), center (1), and right side (2). By default it's actions toolbar on the first line, visible fields settings button and page index at the left and page size at the right of the second line. | footerRenderer | ( props: HeaderFooterPropsType ) | DefaultFooter | Component (function) used to render table footer with pagination and page size selector | | headerElements | (() => JSX.Element)[][][] | | Elements to be rendered by DefaultHeader before page at the left (0), center (1), and right side (2). By default it's visible fields settings button and page index at the left and page size at the right. | headerRenderer | ( props: HeaderFooterPropsType ) | DefaultHeader | Component (function) used to render table header with pagination and page size selector | | itemFieldCellHyperlink | (item: T, field: FieldModel<T, unknown>) => string | () => null | Allow to wrap cell content in hyperlink element (<a>). Will not be used when pageTable has at least single selected element. | | itemFieldCellLinkWrapper | (props: ItemFieldCellLinkWrapperProps<T, unknown>) => JSX.Element | DefaultItemFieldCellLinkWrapper by default. ReactRouterItemFieldCellLinkWrapper when react-router integration enabled | Implement hyperlink wrapper. By default it's usual <a> element (with appropriate styling to fill whole cell). Replaced with react-router-dom <Link> element when integration is enabled and provided hyperlink value is relative. | | itemFieldCellRenderer | ( props: ItemFieldCellRendererProps ) => JSX.Element | DefaultItemFieldCellRenderer | Allows to override default item cell renderer (including selection checkbox cell). | | onSelectedIdsChange | (string[]) => unknown | undefined | Selection change listener (ids) | |onSelectedItemsChange |((T|undefined)[]) => unknown | undefined | Selection change listener (items). Can return undefined item if selected ID is not present on current page anymore. | | noContentRow | ( tableColumnsCount: number ) => ReactNode | "no content on this page, select another page to display" | What to display instead of row when no data present on the fetched page | | rowsRenderer | ( props: RowsRendererProps ) => JSX.Element | DefaultRowsRenderer | Allows to override default rows renderer. | | rowProps | ( item: T ) => React.ComponentProps<'tr'> | () => ({}) | Additional properties for inner <tr> element | | size | undefined | 'lg' | 'sm' | undefined | Will be passed to react bootstrap Table component as well as to Button, Form.Control and other inner components to change their visible size. | | tableProps | props of react bootstrap <Table> component | {} | Additional properties for inner <Table> component | | urlParamsPrefix | string | "" | What is the prefix of page, size, sort and other URL arguments that PageTable should interact with. Only with react-router integration enabled. |

Item model

So far itemModel (itemModel: ItemModel) defines 2 properties:

• idF (idF: (item: T) => string). Defines a way to get unique identifier of object in the data list. It's usually object ID. Identifier should be unique in single data page scope and shall be unique in whole table scope. Internally it's used to store selected rows identifiers and to provide key to React element array items.
• fields (fields: FieldModel<ItemModel, FieldValueType>[]). List of object properties that can be displayed in the table. Some of them are visible by default, some of them are hidden. Use can change this (along with order of fields). Each field model should have following properties:
  • key (key: string). Defines internal string key for field. Internally it's used to provide key to React element array items. In future versions it will also be used to store 'shown/hidden' lists of column. Assumed to be safe to change from version to version (nothing really bad happens on change).
  • title (title: string). Field title text. Shown in table column header cell. Title is string due to DOM limitations related to <option> tag behavior (for example it's used in visible fields list dialog).
  • description (description?: ReactNode): Description of field. Optional. Currently unused.
  • sortable (boolean): is field sortable or not. Optional. Default false. Enabling this will render additional sorting icons in table header cell and will allow user to change sorting by clicking on header cell. Component does not define a way to sort elements, only fills sort field in FetchArgs structure passed to fetch() function.
  • getter (getter?: ( item: I, fieldModel: FieldModel<I, V>, itemModel: ItemModel<I> ) => V). Optional. Defines the way to obtain field value from object structure. By default obtains object property using key, i.e. item[fieldModel.key].
  • render (render: ( props: { value: V, item: I, itemModel: ItemModel<I> } ) => ReactNode). Optional. Defines the way to render object field as table cell content. By default just outputs string and number values as ReactNode, objects are stringified using JSON.stringify(), null and undefined are returned as null. Feel free to use function, React functional component or React class component here. Props type is exported from library as ValueRendererProps interface.
  • headerCellContent (props: ( field: FieldModel<ItemModel, FieldValueType> ) => JSX.Element). Optional. Allow to change default header cell react element (<th>) content. By default cell title is renderer with additional icons if field is sortable.
  • valueCellProps (valueCellProps?: ( value: V, item: unknown, fieldModel: FieldModel<V> ) => Record<string, unknown>). Optional. Provides additional value cell react element (<td>) properties.

Example

Data example:

[
  { "id": "1", "name": "Alice", "birthday": "2001-02-03" },
  { "id": "2", "name": "Bob", "birthday": "2002-03-04" },
  { "id": "3", "name": "Carl", "birthday": "2003-04-05" }
]

Possible item model:

const itemModel = {
  idF: ( { id } ) => id,
  fields: [
    { key: 'name', title: 'Name', sortable: true },
    {
      key: 'birthday',
      title: 'Birth Date',
      render: ( { value } ) => new Date( Date.parse( value ) ).toLocaleDateString(),
      sortable: true,
    },
    {
      key: 'birthyear',
      title: 'Birth Year',
      getter: ( { birthday } ) => new Date( Date.parse( birthday ) ).getFullYear(),
      sortable: true,
    },
  ]
}

fetch()

fetch: ( fetchArgs: FetchArgs, fetchOptions: FetchOptions, fetchReason: FetchReason ) => Promise<Page<T>>

interface FetchArgs {
  /** 0-based page to fetch */
  page: number,
  /** Max number of items per page to fetch */
  size: number,
  /** Filter values filled by filter cells (by invoking onFilterByChange callback) */
  filter?: Record<string, unknown>;
  /** Sort by field.
  If multiple fields are specified sort done in order is from last to first.
  (i.e. reversed before put in (for example) ORDER BY clause of SQL query) */
  sort?: { field: string, direction?: 'ASC' | 'DESC' }[]
}

// Additional options to pass to fetch() implementation.
// Can be just passed as fetch( ... , { ...fetchOptions, /* other options */ } )
interface FetchOptions {
  // value of new AbortController().signal to pass to fetch
  signal?: AbortSignal,
}

export enum FetchReason {
  FIRST_TIME_FETCH,
  FETCH_ARGS_CHANGE,
  REFRESH_REQUIRED,
}

/**
* Structure of type is same as Spring Data Page type, thus server result
* can be pass to PageTable without transformation.
*/
interface Page<T> {
  content: T[];
  number: number;
  totalElements: number;
  totalPages: number;
}

Provides a way to get items to display. User shall not think about bouncing/scheduling/etc, just provide data fetch implementation. page field is 0-based.

Header and footer customization

First of all there are headerRenderer and footerRenderer props of PageTable that allow to override header and footer rendering completely. Default implementation uses ControlledContext (and yours can too) to get access to controllable component props (such as current page and others).

Additionally there is headerElements and footerElements props that allows to pass array of elements to be drawn in header and footer. This is array of lines, line is array of columns, column is array of component classes (functions) that shall be rendered in header and footer. Default values are:

• For header: [ [ [ VisibleFieldsButton, PageIndexSelector ], [ PageSizeSelector ] ] ]
• For footer: [ [ [ VisibleFieldsButton, PageIndexSelector ], [ PageSizeSelector ] ], [ [ ActionsToolbar ] ] ]

Parts of header and footer are exported as:

• DefaultFooter and DefaultHeader -- default implementation of header and footer
• ActionsToolbar -- action buttons toolbar (button toolbar)
• PageIndexSelector -- pagination control
• PageSizeSelector -- page size select control
• VisibleFieldsButton -- button to show visible fields dialog

Utility functions

fetchFromArray

Emulates fetching data from provided array. Supports pagination and sorting (with strings and numbers).

import { fetchFromArray } from '@vlsergey/react-bootstrap-pagetable';

async function fetchFromArray<T>(
    itemModel: ItemModel<T>,
    src: T[],
    fetchArgs: FetchArgs ): Promise<Page<T>>

fetchFromSpringDataRest

import { fetchFromSpringDataRest } from '@vlsergey/react-bootstrap-pagetable';

async function fetchFromSpringDataRest<K extends string, T>(
  url: string,
  fetchArgs: FetchArgs,
  responseCollectionKey: K ): Promise<Page<T>>

Fetches data from Spring Data REST API. Provided URL can be absolute or relative. Fields keys to sort or to filter assumed to be passed to server without modifications. Convert "virtual" fields to server ones before providing fetchArgs to function.

responseCollectionKey is the name of result collection element inside of _embedded structure in response.

springDataRestResponseToPage

import { springDataRestResponseToPage } from '@vlsergey/react-bootstrap-pagetable';

interface SpringDataApiResponseType<K extends string, T> {
  _embedded: {
    [P in K]: T[];
  };
  page: {
    size: number;
    totalElements: number;
    totalPages: number;
    number: number;
  };
}

function springDataRestResponseToPage<K extends string, T>(
    key: K, response: SpringDataApiResponseType<K, T>
): Page<T>

Converts Spring Data REST API response to Page structure expected by PageTable. key is the name of content collection in _embedded structure.
