With a React Data Grid, the page code looks something like this:

For displaying charts and other graphics, I need to rely on third-party libraries. In the above case, I installed react-sparklines to demonstrate a sparkline. The columns are defined using an object. For the sparkline, I fall back to a custom formatter without a backing field.

The result shows up like this:

Now let's display the same data with FlexGrid. For about the same amount of code, you get a much better looking and more flexible display of data. The page code now looks like this:

Most notably, the Wijmo data grid defines the columns declaratively in React. For the sparkline cell, a CollectionView is used. Using useState, I can cache the data and keep it alive between re-renderings — no expensive computation required.

Here, the default result has a look that resembles a real spreadsheet app:

Since the data grid is the largest component in the application, it's good practice to lazy-load it. If you'll only use the data grid on a single page, it's sufficient to lazy-load that particular page and avoid additional complexity:

The only requirement is that the lazy-loaded module have a proper default export:

All unique dependencies (for instance, the data grid component) should be contained in the side-bundle. This side-bundle will have a significant impact on startup performance.

Best Practices for Loading Data

In these examples, I just loaded some hard-coded data. In real applications, you're most likely going to grab dynamic data from an external source like a file, a database, or an API.

While loading data is usually considered a mostly back-end topic, there are some front-end considerations that need to be discussed. Most importantly, having an API that delivers non-bounded amounts of data would be problematic. One common issue is that the rendering of the entire dataset is either really slow or only happening in chunks, leaving parts of the data unused.

To circumvent the above issues, some APIs allow pagination. In the most simple form, you communicate a page number to the API, which then calculates the offset in the dataset. For reliable pagination and maximum flexibility, the pagination mechanism actually should use a pointer – a marker for the last emitted data item.

To include a paginated API in the Wijmo data grid, use an ICollectionView instance. If your API supports OData, then you can simply use the ODataCollectionView for this task.

For instance, the following view serves six items per page:

In general, standard CollectionView can be used for asynchronous data loading, too: Xin zhao build wild rift.

The code above is not perfect: asynchronous operations should be appropriately cleaned up with a disposer. A better version of useEffect would be:

Besides calling the API directly, you may be concerned with cross-origin resource sharing (CORS). CORS is a security mechanism in the browser that affects performing requests to domains other than the current one.

One crucial aspect besides the implicit CORS request and response pattern, including the so-called preflight requests, is the delivery of credentials by, for example, a cookie. By default, the credentials are only sent to same-origin requests.

The following will also deliver the credentials to other services – if the service responded correctly to the preflight (OPTIONS) request:

React

So far, data calling has been done on mounting the component. This method is not ideal. It not only implies always needing to wait for the data but also makes cancellations and other flows harder to implement.

What you want is some global data state, which could be easily (and independently of a particular component's lifecycle) accessed and changed. While state container solutions, such as Redux, are the most popular choices, there are simpler alternatives.

One possibility here is to use Zustand ('state' in German). You can model alls React UI controls free for 30 days
