Working without server

[Cattn]

So I know the official page has a way to package a rom as a data string (I think that's what it does) and then load it in without a web server, I was wondering how you were able to convert the rom to the long data, and if you could point out either some docs about how to use the window.gameData, or something else of the like. I looked through docs and didn't see much about it

Any help would be appreciated!

JSON.stringify(Array.from(new Uint8Array(await (new Blob([file])).arrayBuffer())));

Whenever I upload a file it only outputs in a length of 17 in the array
This is what I'm trying currently, It is able to get the file fine, I'm not sure if I'm doing something wrong past that.
let input = document.querySelector('input')
input.addEventListener('change', () => {
let file = input.files;
async function convertFile() {
let test = JSON.stringify(Array.from(new Uint8Array(await (new Blob([file])).arrayBuffer())));
console.log(test);
console.log(file);
}
convertFile();
});

let file = input.files; needs to be let file = input.files[0];

Thank you so much that solved it!
