Ably is a provider of real-time data delivery solutions that support the creation, delivery, and management of complex projects. The Ably API facilitates communication between the Ably service and a variety of client and server devices. The RESTful API is designed for use in servers that form part of the back-end of any given application, like a web application, that implement messaging concepts. The functional scope of the Ably REST API spans the authentication, message publication and message history retrieval as well as presence state and presence retrieval and application usage data retrieval. The API returns responses in mainly JSON format, although JSONP and HTML formats are also acceptable.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
