Bring in modules from a JavaScript library into TypeScript

I'm facing a challenge in importing an external JavaScript library that lacks typings or an installable package. The specific plugin I am trying to import is located at: https://github.com/amw/jpeg_camera/tree/master/dist/jpeg_camera_no_flash.js. What I aim to do is import three classes from this plugin: JpegCamera, JpegCameraHTML5, and Snapshot. After following some tutorials, I managed to define the structure of these classes along with their interfaces in a separate .d.ts file. Here's how the .d.ts file looks like:

declare module Camera {}<br>
export class JpegCamera {...}<br>
export class JpegCameraHTML5 {...}<br>
export class Snapshot {...}

My current roadblock lies in establishing a connection between the source file of the plugin (.js), my custom .d.ts file, and the TypeScript file where I intend to import these three classes. I attempted to use:
import * as X from "path/to/d.ts
but unfortunately, it didn't yield the desired outcome. Any insights would be appreciated! Thank you :)

Answer №1

If you are running your application in a certain context and encountering an issue, it is worth noting that when I attempted to run it locally, I received the following message:

ReferenceError: document is not defined
while using the syntax:
import * as camera from './jpeg_camera_no_flash'

This error should not occur if your script is being executed through a web browser.

To address this matter, I physically downloaded the file to my project folder.

Answer №2

One possible solution is to attempt the following approach:

/// <reference path="path to the .d.ts" />

Another option would be to export each class with the default keyword, allowing you to import them in this manner:
import className from './file-path'
