It includes a configurable automatic retry mechanism with backoff strategies, a built-in HTTP response cache, and a cookie-jar system for maintaining persistent sessions. Broad capabilities cover data handling through duplex

Gron is a command line utility that transforms nested JSON data into a flat list of path-value assignments. This process converts hierarchical structures into line-based statements, mapping every leaf value to its absolute path to make the data compatible with standard text-processing tools. The tool allows for the bidirectional transformation of data, enabling the reconstruction of original nested JSON objects from flattened path assignments. It can ingest JSON from local files, standard input, or remote URLs, with the ability to route network traffic through proxy servers. The utility supp

Proxygen is a collection of C++ libraries for building high-performance HTTP servers and clients. It provides a protocol parser that converts raw network bytes into high-level transaction objects and includes a network stack for processing web traffic over the QUIC transport protocol. The project implements a layered protocol abstraction and a QUIC-based transport integration to support multiple versions of the HTTP standard, including HTTP/3. It utilizes state-machine based parsing and an event-driven I/O loop to manage concurrent network connections. The library covers asynchronous buffer

WeixinBot is a framework for WeChat account automation and bot development. It provides a programmable interface to monitor incoming messages and trigger automated actions within the WeChat ecosystem. The system emulates a browser session using a WebSocket-based protocol and establishes identity through QR code authentication. It maintains session-state persistence to keep accounts active without repeated verification. The project covers message processing for text, images, voice notes, and location data, and supports the transmission of emojis and links. It includes utilities for user conta

oboe.js ist ein Streaming-JSON-Parser und HTTP-Stream-Client für die inkrementelle Datenverarbeitung. Er ermöglicht es Anwendungen, auf einzelne JSON-Objekte zu reagieren, sobald diese von einer Netzwerkanfrage oder einem lesbaren Stream eintreffen, noch bevor der gesamte Download abgeschlossen ist. Die Bibliothek fungiert als JSON-Stream-Transformer und ermöglicht das Modifizieren, Filtern und Mappen von Knoten zur Laufzeit. Sie bietet pfadbasierte Knotenauswahl, um Callbacks bei Übereinstimmung mit bestimmten Mustern auszulösen, und kann Netzwerkverbindungen vorzeitig beenden, sobald die benötigten Daten gefunden wurden, um Bandbreite zu sparen. Um Datensätze zu verarbeiten, die den verfügbaren Arbeitsspeicher übersteigen, nutzt die Bibliothek ein stream-basiertes Speichermanagement, um verarbeitete Knoten zu verwerfen. Sie unterstützt zudem das Zusammenführen historischer Datensätze mit Echtzeit-Updates über langlebige Verbindungen und bietet die Möglichkeit, bei Verbindungsabbrüchen teilweise Daten wiederherzustellen.

Beast ist eine C++-Bibliothek zur Implementierung von Low-Level-HTTP- und WebSocket-Clients sowie -Servern. Es fungiert als asynchrones Networking-Framework, das darauf ausgelegt ist, nicht-blockierende I/O-Operationen und geschichtete Stream-Stacks zur Verwaltung von gleichzeitigem Netzwerkverkehr zu kombinieren, wobei speziell das asynchrone Modell von Boost.Asio genutzt wird. Die Bibliothek bietet eine umfassende Implementierung der HTTP/1.1- und WebSocket-Protokolle. Für HTTP enthält sie Primitive zum Parsen und Serialisieren von Nachrichten mit Unterstützung für Chunked-Transfer-Encoding, inkrementelles Body-Lesen und Request-Pipelining. Die WebSocket-Implementierung deckt den gesamten Lebenszyklus der bidirektionalen Kommunikation ab, einschließlich Handshakes, Subprotokoll-Aushandlung, Nachrichtenfragmentierung und Liveness-Monitoring via Control-Frames. Beast enthält eine spezialisierte Suite von Tools für das Netzwerk-Buffer-Management, um Scatter-Gather-I/O durch dynamische und sequenzbasierte Speicherpuffer zu optimieren. Es deckt zudem sichere Netzwerkkommunikation durch die Integration von SSL/TLS-Layern für verschlüsselte Streams, Zertifikatsauthentifizierung und sichere Verbindungsbeendigung ab. Das Framework bietet plattformübergreifende Abstraktionen für Datei-I/O und System-Signal-Management, um die Entwicklung stabiler Netzwerkanwendungen zu unterstützen.
