Uncomplited, demo Mega.nz JS library.

It works, but supports only some features:

listing,
thumbnails/previews downloading.

npm ci
npm run build

To open a web demo run a http server in the root folder, then open a html file from _examples-browser directory.

Or try to use a Node.js demo from _examples-node directory. (Note: remove import * as URLS from "./test-urls-private.js"; first and use your own Mega URL.)

The example usage

Downloading of thumbnails:

https://github.com/AlttiRi/meganz-api/blob/master/_examples-node/ex-3.3-ok.js:

import {saveFile} from "./util-node.js";
import {Nodes} from "../src/mega.js";

const nodeArray = await Nodes.nodes("https://mega.nz/..."); // Use your own URL

const promises = [];
let i = 0;
for (const node of nodeArray) {
    if (Nodes.isMediaNode(node)) {
        const index = (++i).toString().padStart(3, "0");
        console.log(`${index} ${node.name}`);
        const filename = `thumbnail-${index}-${node.id}.jpg`;
        const downloaded = node.getThumbnail()
            .then(thumb => {
                void saveFile(thumb, filename, node.mtime);
            });
        promises.push(downloaded);
    }
}
await Promise.all(promises);

Multiple API requests are grouped within one API request when it's possible.
Multiple thumbnails data are downloaded within one download request when it's possible.
All similar HTTP connections are performed concurrently, but not more that 16 at one moment. See Semaphore class.
Also it uses custom (much faster (up to x9 times)) convertation from ArrayBuffer to WordArray of CryptoJS library. See /src/crypto.js.
