海外TECH	DEV Community	Save your clients internet, Serving big JSON dataset files over network like a pro	https://dev.to/rajeshroyal/save-your-clients-internet-serving-big-json-dataset-files-over-network-like-a-pro-4fde	Save your clients internet Serving big JSON dataset files over network like a proEver needed to server big JSON files over the network like MB files The efficient way we can handle this problem is by converting the JSON files to binary and then send it to the client Firs lets just convert JSON to gz file and see the size difference Comparison Actual file size MB compressed gz file size MB Linux command to convert JSON to gzgzip filename json It will convert your file to the gz file Now you can easily server this file over the network and the client will have to decode the file from gz file to JSON A useful library to convert binary data to string is pako Use below code in React js to convert gz to json file import inflate from pako const parse bin any gt inflate bin to string export const fetchJSON gt return fetch data data json gz then async response gt const blob await response blob readSingleFile blob then res gt let jsonData parse rs console log jsonData return jsonData async function readSingleFile file File Blob return new Promise resolve reject gt const reader new FileReader reader onload function e resolve e target result reader readAsArrayBuffer file reader onabort reject reader onerror reject Why this article even make sense Well recently I was working with deck gl and had to render big JSON dataset files over MB If the files were locally present that s OK but imagine serving those dataset files from a CDN For same problem I researched over the internet about how to serve large dataset files efficiently optimize in deck gl and found nothing and at last I end up with doing binary conversion and decoding those files in browser to render map contents I know this is not the optimal approach but If anyone has a better approach or has any experience with deck gl of rendering large datasets Please comment down below Thanks	2023-01-28 09:41:52
