Using TypeScript with CanvasJS

While working on my TypeScript project, I encountered an issue with integrating CanvasJS using the declaration file - index.d.ts. The corresponding JavaScript file can be found at . I am utilizing require.js in my project, but it crashes when running because it couldn't locate the index.js it was looking for. One workaround is to create an index.js and paste the contents of , which resolves the issue.

However, instead of this approach, I would prefer for the index.d.ts file to directly reference or fetch the URL. Is there a way to achieve this?

Answer №1

One reason for this is because the `index.d.ts` file only contains the definition and does not actually import any libraries. A recommended solution would be to use `npm install canvasjs` to install the package, then add the types using `npm install --save @types/canvasjs`. This will place the canvasjs library into the `node_modules` directory. When trying to import it using

import CanvasJS from 'canvasjs';

TypeScript will attempt to resolve the library import following specific rules. In essence, it will recursively search for the `node_modules` folder starting from the file where canvasjs is being imported and continuing upwards through parent folders if necessary.

Another approach would be to include the import `

https://canvasjs.com/assets/script/canvasjs.min.js
` in the header of your HTML file (assuming you have one) or within your JavaScript code, install the typings via `npm install --save @types/canvasjs`, and adjust the `tsconfig.json` accordingly:

{
   "compilerOptions": {
       "types" : ["canvasjs"]
   }
}
