Download files using Axios.js

/**
 * Download files and save it to disk using axios.js
 * Download images, zip files using this function 
 * 
 * @param {Request URL} reqUrl 
 * @param {File name} fileName 
 */
function downloadFile(reqUrl, fileName){
    axios({
        method: "GET",
        url: reqUrl,
        responseType: "stream"
    }).then(res => {
        if (res.status == 200) {
            const path = require("path");
            const SUB_FOLDER = SUB_FOLDER || "";
            fileName = fileName || reqUrl.split("/").pop();

            const dir = path.resolve(__dirname, SUB_FOLDER, fileName);
            res.data.pipe(fs.createWriteStream(dir));
            res.data.on("end", () => {
                console.log("download completed");
            });
        } else {
            console.log(`ERROR >> ${res.status}`);
        }
    }).catch(err => {
        console.log("Error ",err);
    });
}

Thanks for this approach, but this line should be const SUB_FOLDER = process.env.SUB_FOLDER || "";, otherwise there should be an Error.

Thank you recently came in handy
