问题描述
I have the url to a possibly large (100+ Mb) file, how do I save it in a local directory using fetch?
I looked around but there don't seem to be a lot of resources/tutorials on how to do this.
Thank you!
解决方案
Using the Fetch API you could write a function that could download from a URL like this:
const downloadFile = (async (url, path) => {
const res = await fetch(url);
const fileStream = fs.createWriteStream(path);
await new Promise((resolve, reject) => {
res.body.pipe(fileStream);
res.body.on("error", reject);
fileStream.on("finish", resolve);
});
});
