Package centrifuge is a real-time messaging library that abstracts several bidirectional transports (Websocket and its emulation over HTTP-Streaming, SSE/EventSource) and provides primitives to build scalable real-time applications with Go. It's also used as a core of Centrifugo server (https://github.com/centrifugal/centrifugo). Centrifuge library provides several features on top of plain Websocket implementation and comes with several client SDKs – see more details in the library README on GitHub – https://github.com/centrifugal/centrifuge. The API of this library is almost all goroutine-safe except cases where one-time operations like setting callback handlers performed, also your code inside event handlers should be synchronized since event handlers can be called concurrently. Library expects that code inside event handlers will not block. See more information about client connection lifetime and event handler order/concurrency in README on GitHub. Also check out examples in repo to see main library concepts in action.

Package bugsnag captures errors in real-time and reports them to BugSnag (http://bugsnag.com). Using bugsnag-go is a three-step process. 1. As early as possible in your program configure the notifier with your APIKey. This sets up handling of panics that would otherwise crash your app. 2. Add bugsnag to places that already catch panics. For example you should add it to the HTTP server when you call ListenAndServer: If that's not possible, you can also wrap each HTTP handler manually: 3. To notify BugSnag of an error that is not a panic, pass it to bugsnag.Notify. This will also log the error message using the configured Logger. For detailed integration instructions see https://docs.bugsnag.com/platforms/go. The only required configuration is the BugSnag API key which can be obtained by clicking "Project Settings" on the top of your BugSnag dashboard after signing up. We also recommend you set the ReleaseStage, AppType, and AppVersion if these make sense for your deployment workflow. If you need to attach extra data to BugSnag events, you can do that using the rawData mechanism. Most of the functions that send errors to BugSnag allow you to pass in any number of interface{} values as rawData. The rawData can consist of the Severity, Context, User or MetaData types listed below, and there is also builtin support for *http.Requests. If you want to add custom tabs to your bugsnag dashboard you can pass any value in as rawData, and then process it into the event's metadata using a bugsnag.OnBeforeNotify() hook. If necessary you can pass Configuration in as rawData, or modify the Configuration object passed into OnBeforeNotify hooks. Configuration passed in this way only affects the current notification.

Package kinesisanalyticsv2 provides the API client, operations, and parameter types for Amazon Kinesis Analytics. Amazon Managed Service for Apache Flink was previously known as Amazon Kinesis Data Analytics for Apache Flink. Amazon Managed Service for Apache Flink is a fully managed service that you can use to process and analyze streaming data using Java, Python, SQL, or Scala. The service enables you to quickly author and run Java, SQL, or Scala code against streaming sources to perform time series analytics, feed real-time dashboards, and create real-time metrics.

Package rtcp implements encoding and decoding of RTCP packets according to RFCs 3550 and 5506. RTCP is a sister protocol of the Real-time Transport Protocol (RTP). Its basic functionality and packet structure is defined in RFC 3550. RTCP provides out-of-band statistics and control information for an RTP session. It partners with RTP in the delivery and packaging of multimedia data, but does not transport any media data itself. The primary function of RTCP is to provide feedback on the quality of service (QoS) in media distribution by periodically sending statistics information such as transmitted octet and packet counts, packet loss, packet delay variation, and round-trip delay time to participants in a streaming multimedia session. An application may use this information to control quality of service parameters, perhaps by limiting flow, or using a different codec. Decoding RTCP packets: Encoding RTCP packets:

Gotalk is a complete muli-peer real-time messaging library. See https://github.com/rsms/gotalk#readme for a more in-depth explanation of what Gotalk is and what it can do for you. Most commonly Gotalk is used for rich web app development, as an alternative to HTTP APIs, when the web app mainly runs client-side rather than uses a traditional "request a new page" style. Here is an example of a minimal but fully functional web server with Gotalk over websocket: Here is a matching HTML document; a very basic web app: Gotalk can be thought of as being composed by four layers: You can make use of only some parts. For example you could write and read structured data in files using the message protocol and basic file I/O, or use the high-level request-response API with some custom transport.
