Download url

downloadFileFromUrl is a function that receives three parameters:

• url: The url of the file to download.
• destination: The destination path to save the file to.
• fileName: Optionally The file name to save the file with.

It fetches the file from the given url and saves it to the given destination path.

Usage

src/app/posts/controllers/get-posts.ts

import {
  storagePath,
  downloadFileFromUrl,
  Request,
  Response,
} from "@warlock.js/core";

export default async function getPosts(request: Request, response: Response) {
  const response = await downloadFileFromUrl(
    "https://example.com/image.jpg",
    storagePath("images")
  );

  // rest of the code
}

If the third argument is not passed, then the function will generate a random file name but keep the file extension.

The output of the function is AxiosResponse.

danger

The function will throw an error if the given url is not valid.

warning

The function is not going to create the directory if it doesn't exist, so make sure to create it before calling the function.
