Error when calling pause or stop method

[Luury]

When I call the pause() function using a download object, the following error occurs:

what is the correct way to call the function just passing the object?

You don't pass the object, pause() is a method on the download object.

So you could do:

const downloadObject = new DownloaderHelper(`http://example.com/download`, __dirname)

downloadObject.start().then(() => {
  setTimeout(() => downloadObject.pause(), 3000)
})

Sorry for my bad English, I know it's an object method, but I figured out the real problem, I'm using Vue 3, and I stored the download object in vue's data(), and tried using pause() or stop() through it. The other methods work, but for some reason these two don't work, when I do with pure javascript it works, I'm still trying to figure out the problem.

My code:

Data:

  data() {
    return {
      downloads: [],
    };
  },

Methods:

Add Download to data:

 addDownload() {
      const download = {
        name: "Test",
        header_image:
          "https://images.sftcdn.net/images/t_app-cover-l,f_auto/p/ce2ece60-9b32-11e6-95ab-00163ed833e7/260663710/the-test-fun-for-friends-screenshot.jpg",
        status: "",
        downloading: null,
        progress: 0,
        speed: 0,
        size: 0,
        downloaded: 0,
        object: new DownloaderHelper(
          "https://nodejs.org/dist/v14.17.5/node-v14.17.5-x64.msi",
          "./downloads",
          {
            fileName: { name: "Test" }, // Custom filename when saved
            override: { skip: true, skipSmaller: true },
            removeOnStop: true, // remove the file when is stopped (default:true)
            removeOnFail: true, // remove the file when fail (default:true)
          }
        ),
      };

      this.downloads.push(download);
    }

Download: (this works)

    download(item) {
      item.object.on("start", () => {
        item.downloading = true;
      });

      item.object.on("progress", (stats) => {
        item.progress = parseInt(stats.progress);
        item.status = parseInt(stats.progress) + "%";
        item.speed = byteHelper(stats.speed);
        item.downloaded = byteHelper(stats.downloaded);
        item.size = byteHelper(stats.total);
      });

      item.object.on("end", () => console.log("Download Completed"));

      item.object.on("error", (error) => console.log(error));

      item.object.start();
    }

Pause:

    pauseDownload(item) {
      item.object.pause();
      item.downloading = false;
    }

Resume: (this works)

    resumeDownload(item) {
      item.object.resume();
      item.downloading = true;
    }

Stop:

    stopDownload(item) {
      item.downloading = false;
      item.object.stop();
    }

Stats: (this works)

    statsDownload(item){
      console.log(item.object.getStats())
    }

@Luury what i suspect is happening, is that when the download objects are store in vue data, they are treated as browser object, and this library only works in the nodejs context, what i would suggest is just keep the downloader object outside the vue data, and try to map them by id or something that you can call refer to them later

@hgouveia, You're right, that solved the problem.
