I am trying to run an example to display a chart create using in Kendo React.
The example is on this tutorial: https://www.telerik.com/kendo-react-ui/components/charts/chart/elements/chart-area/
I have made a few changes to be able to run it via browser, without installing npm packages locally. However, I am unable to display this. I get an error in the console
Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
Check the render method of ChartContainer. at ChartContainer
What am I missing??
...ANSWER
Answered 2021-Dec-17 at 23:15The reason this snipped is failing is because ChartArea, ChartSeries and ChartSeriesItem are not found on the kendo-react-all library. You need to import kendo-react-chart.js.
https://unpkg.com/@progress/kendo-react-charts/dist/cdn/js/kendo-react-charts.js
Also, you need to change the source module from window.KendoReactAll to window.KendoReactCharts
At the end it should look like this:

ANSWER
Answered 2021-Nov-26 at 19:18You only call RecreateDataArray when the component mounts, not when props change.
That's why it doesn't update when your props change.
You could do that update with a componentWillUpdate lifecycle method, but it will be a lot easier to just refactor to a function component and use the useEffect hook instead:
QUESTION
I have recently ejected Create-React-App and reconfigured many stuff! however, I still can't get the tests working... I get the following error :
ANSWER
Answered 2021-May-19 at 05:03According to Jest:
Modules that are mapped to an alias are unmocked by default, regardless of whether automocking is enabled or not.
This means the mapped module test-utils, is trying to import a module that is not mocked, thus the import error.
If you'd wanted to create an alias for your tests like the 'test-utils' I've been trying to do, you should use moduleDirectories instead.
ModuleDirectories is an array of directory names to be searched recursively up from the requiring module's location. The default value is node_modules and in fact this is how Jest imports your third-party libraries into the tests.
Here is an example that will create an alias to a folder named 'utils':
QUESTION
My team recently have been running into an odd error when trying to npm start a Create React App we are developing. The error is Bad state: Can't access __parent outside of a module which is causing the Build to fail. We have used this setup for about a year without having this issue. The node-sass version we are using is "node-sass": "npm:sass@^1.32.5" It is a dart Sass implementation. We have tried reinstall node modules and clearing npm cache to no avail. Any suggestions would be much appreciated. The full error message is below.
ANSWER
Answered 2021-May-12 at 17:18Ok, so we recently figured out the issue. A stylesheet was referenced in the app from a node module. The node module was updated and the path to the stylesheet did not exist anymore. For some reason the linter only had an issue with it when a production build was being created. The error message was very vague. We use Create React App and its configurations for building a production app.

I have been working at this for 2 days and can not seem to figure out what it is that I am doing wrong. I did get the data to represent before I brought redux in.

If there is any clarification on things, please, let me know.
