• High efficiency;
• Automatically caching WebAssembly binary into indexedDB;
• UMD supported, easy to use in frontend;
• Part of functions moved from php-src;
• The maximum availabe memory space is up to 64MB;

import eufa from 'eufa';

// Init eufa first
eufa.init('static/eufa-module.wasm', () => {
    console.log(eufa.Encryptor.base64_encode('Hello WebAssembly, hello Eufa :)'));
});
