ReactJSCharts + Typescript

[Emin500]

I’m working on a project with React and Typescript. I’m running into an error that’s stemming from the import of the CanvasJSReact chart import (import CanvasJSReact from ‘@canvasjs/react-charts’) . The error shows up as “TS7016: Could not find a declaration file for module ‘@canvasjs/react-charts’. ‘C:/…/../…/…/node_modules/@canvasjs/react-charts/canvasjs.react.js’ implicitly has an ‘any’ type.” When I run npm start, the website runs and the graph is displayed, but the error message does not go away.

Does this package include a type declaration for typescript uses?

I did npm install for both @canvasjs and for @canvasjs/react-charts, but still getting the same error. Would love some help.

@emin500,

React charts seem to be working fine with typescript. Please take a look at this Stackblitz code for a working example.

If you are still facing issue, kindly create a sample project reproducing the issue you are facing and share it with us over Onedrive / Google-Drive, so that we can run the sample locally at our end to understand the scenario better and help you out.

Even the Stackblitz shows a typescript error:
Cannot find module '@canvasjs/react-charts' or its corresponding type declarations.

if you hover over ‘@canvasjs/react-charts’ in the import statement

@gojukeboxgmail-com,

We don’t have CanvasJS React Charts TypeScript definition as of now. However, charts seems to work fine with React TypeScript as-well. You can ignore the corresponding error in Stackblitz by adding // @ts-ignore above the import statement as shown in the code-snippet below.

// @ts-ignore
import CanvasJSReact from '@canvasjs/react-charts';
