Getting started #
Install with dart pub add s5
Example #
import 'dart:convert';

import 'package:hive/hive.dart';
import 'package:s5/s5.dart';

void main(List<String> args) async {
// Initialize the Hive data directory (not needed on web)
Hive.init('data');

// Create a S5 Node and API Client
final s5 = await S5.create();

// Download and deserialize a metadata CID
final webAppMetadata = await s5.api.downloadMetadata(
CID.decode(
'z31rd7XSsfcDuuv716hjfbjitjCMRrfwPE24EWSuJntFKCdK',
),
) as WebAppMetadata;

// Print all files of this web app with their CID and size
for (final path in webAppMetadata.paths.entries) {
print('${path.key} ${path.value.cid} (${path.value.cid.size} bytes)');
}

// Download one of the CSS files and print its contents
final cssFileCID = webAppMetadata.paths['assets/css/default.min.css']!.cid;
final bytes = await s5.api.downloadRawFile(cssFileCID.hash);
print(utf8.decode(bytes));
