probe-image-size VS astro-imagetools

import React, { useState } from "react"; const url = require("url"); const http = require("http"); const sizeOf = require("image-size"); function Upload() { const [photoName, setPhotoName] = useState(""); const [photoLink, setPhotoLink] = useState(""); const [submittedData, setSubmittedData] = useState([]); const [errors, setErrors] = useState([]); function handlePhotoNameChange(event) { console.log("handlePhotoNameChange"); setPhotoName(event.target.value); } function handlePhotoLinkChange(event) { console.log("handlePhotoLinkChange"); setPhotoLink(event.target.value); } function handleSubmit(event) { event.preventDefault(); if (photoName.length > 0) { // TODO: // Use 'probe-image-size' library to determine width and height of the image the user passed in // Then, add a 'width' and 'height' key value to the 'formData' variable so that the // values are then added back to 'db.json' accordingly: // https://github.com/nodeca/probe-image-size const options = url.parse(photoLink); // 'http.get()' request so that I can obtain the image itself: http.get(options, function (response) { const chunks = []; response .on("data", function (chunk) { chunks.push(chunk); }) .on("end", function () { const buffer = Buffer.concat(chunks); console.log(sizeOf(buffer)); }); }); const formData = { photoName: photoName, photoLink: photoLink }; const dataArray = [...submittedData, formData]; setSubmittedData(dataArray); setPhotoName(""); setPhotoLink(""); setErrors([]); console.log("handleSubmit() called"); console.log("dataArray (before fetch() call): ", dataArray); fetch("http://localhost:3000/photos", { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ dataArray: dataArray, }), }) .then((response) => response.json()) .then((response) => { console.log("response (from fetch request): ", response); }); } else { setErrors(["Name of photo is required!"]); } } const listOfSubmissions = submittedData.map((data, index) => { return ( {data.photoName} {data.photoLink} ); }); return ( Upload Image To Board Name: Link: Upload {errors.length > 0 ? errors.map((error, index) => ( {error} )) : null} Recent Submissions Below: {listOfSubmissions} ); } export default Upload;

Again, there are multiple ways to get dimensions and your development pipeline might just provide this information by default. In case it doesn't, we have found a nice and small npm package called probe-image-size. It allows for 'probing' an image locally or remotely.

I found that my SSR pages loaded very slowly because I was using astro-imagetools to process images. Since optimized images aren't necessary during editing anyways, I created a wrapper component to bypass image processing in the preview environment:

In our case, using Astro, we simply used astro-imagetools to compress images automatically while importing them. We might improve this later, for example generating multiple image sizes and formats, reducing the load even further for modern browsers. Currently, it checks our box though.

There is no official Astro solution for working with images, but Astro ImageTools gives Astro the ability to provide optimized, responsive images.4
