    This repository provides React components for rendering tables of JSON data from APIs.


    • Dynamically-rendered filters according to the API response
    • Pagination
    • Sorting
    • Automatic vertical/horizontal table scrolling and layout
    • Persistent URL-based filters
    • Data exporting
    • Token-based authentication

    How to use

    import TableRenderer from "table-renderer/src/TableRenderer"
    const MyTable = function () {
      return (
            fetchEndpoint: "http://foo/api",
            exportEncoding: "text/csv; charset=utf-8",
            exportExtension: "csv",
            exportRequestAcceptHeader: "application/csv",


    All the types mentioned below are gathered in the types module.

    The basic idea is for the client to send a TableRequest and the API to reply with

    • TableResponse with success status code on pagination requests
    • ExportResponse with success status code on export requests
    • ErrorResponse with error status code for error

    Success or failure is determined by the status code and not the shape of the response, which means one should not use a success code for an ErrorResponse and so on.


    The request's body is always sent as JSON via POST.

    For Pagination Requests, the response body's format should be JSON and comply with the structure of TableResponse.

    For Export Requests, the response body's can have any arbitrary content. The response's body will be saved as-is straight into a file and not processed through the application.


    The API should include any missing filters in TableRequest.filters and send them back in the response; each newly-initialized filter might include its default initial value.

    Normally a clean-slate client (one that does not have saved filters from a previous run) sends the first request with an empty filters because it does not yet know which filters are available in the API. is the way to differentiate between Pagination Requests and Export Requests. It is either:

    • A page number, 1-indexed, for paginated browsing; this is what we consider a Pagination Request and therefore the result should be a TableResponse.
    • The word "all", which signals that the API should export all of the data according to the filters; this is what we consider an Export Request and therefore the result should be an ExportResponse.


    The number of items which are included in a page. It should not matter for when is "all".


    This is the number of total records which were matched according to the filters divided by TableRequest.pageSize, rounded up. It should not matter for when is "all".

    Example scenario

    1. The client sends the initial request. In this case it has never used this API before, therefore most fields are empty, but that is not always the case.
      "page": 1,
      "pageSize": 4,
      "filters": [],
      "sort": null
    1. The API responds with the filled default information

    By the returned data, we can infer that there are at most (since it's rounded up) 4 (pageSize) * 2 (pageCount) = 8 records matching the filters, which happen to be empty initially, therefore we can assume there are at most 8 records in total. This response also tells us that the API, by default, sorts the records by "Date" in descending order.

      "page": 1,
      "pageCount": 4,
      "pageSize": 2,
      "filters": [
        { "name": "Date", "value": { "tag": "ISO8601 date", "value": null } },
        { "name": "Item", "value": { "tag": "number", "value": null } },
      "data": [
        { "item": 6, "date": "2021-06-06" },
        { "item": 5, "date": "2021-06-05" },
        { "item": 4, "date": "2021-06-04" },
        { "item": 3, "date": "2021-06-03" },
      "sort": {
        "column": "date",
        "direction": "desc"
        "sortedByDefault": true
    1. The client sends a request for exporting the data.
      "page": "all",
      "filters": [],
      "sort": null
    1. The API sends an arbitrary response, in this case CSV, which the application will download.

    Example project

    We plan to have a minimal project showcasing how to set up an API and front-end, but it's not done yet.
