I wanted to know how to make saveimagetodisk write the files as you go and not all in one block at once
Impossible to do folder manipulation operations after saveImageTodisk because the files are not yet created
CodePudding user response：
You could do this using a fileWriteStream with the built in fs module and whatever modules you use for fetching data here i have used http
const http = require('http')
const URL = `https://pinymedia.web.app/hashtag.png` //Replace with your image
const file = fs.createWriteStream("./file.jpg");
const request = http.get(URL, function(response) {
response.pipe(file);
// after download completed close filestream
file.on("finish", () => {
file.close();
console.log("Download Completed");
});
});
Hope this helps
CodePudding user response：
unfortunately it still doesn't work
function saveImageToDisk(url, path) {
let fullUrl = url;
let localPath = fs.createWriteStream(path);
let request = https.get(fullUrl, function (response) {
// console.log(response);
response.pipe(localPath);
})
// after download completed close filestream
localPath.on("finish", () => {
localPath.close();
console.log("Download Completed");
});
console.log
