Sometimes, we want to load an image from URL into buffer in Node.js and JavaScript.
In this article, we’ll look at how to load an image from URL into buffer in Node.js and JavaScript.
How to load an image from URL into buffer in Node.js and JavaScript?
To load an image from URL into buffer in Node.js and JavaScript, we use Axios.
For instance, we write
const response = await axios.get(url, { responseType: "arraybuffer" });
const buffer = Buffer.from(response.data, "utf-8");
to make a get request to the image url with axios.get.
We get the response as an array buffer by setting the responseType to 'arraybuffer'.
And then we call Buffer.from to convert the response.data response we get from the promise returned by get body to a buffer.
Conclusion
To load an image from URL into buffer in Node.js and JavaScript, we use Axios.
