US 10,542,122 B2 · Event service for local client applications through local server

Abstract

In server/client architectures, the server application and client applications are often developed in different languages and execute in different environments specialized for the different contexts of each application (e.g., low-level, performant, platform-specialized, and stateless instructions on the server, and high-level, flexible, platform-agnostic, and stateful languages on the client) and are often executed on different devices. Convergence of these environments (e.g., server-side JavaScript using Node.js) enables the provision of a server that services client applications executing on the same device. The local server may monitor local events occurring on the device, and may execute one or more server scripts associated with particular local events on behalf of local clients subscribing to the local event (e.g., via a subscription model). These techniques may enable development of local event services in the same language and environment as client applications, and the use of server-side code in the provision of local event service.

Dependent claims

A method of fulfilling requests on a first device having a processor executing a local server application, comprising:

receiving, by the local server application, an event subscription request from a remote client application being executed on a second device, the event subscription request specifying a target server application;
detecting, at the first device, a local event that is
associated with the event subscription request and
one to which the remote client application is subscribed;
sending the event subscription request to a remote server application, which is remote from the first device, when the target server application is determined to be the remote server application;
executing, within the local server application and on behalf of the remote client application, one or more server scripts associated with the local event, after the detecting;
and
executing, within the target server application and on behalf of the remote client application, one or more scripts associated with the event subscription request from the remote client application.

5 more elements

A system, comprising:

a first device having a processor that executes a local server application;
and
a second device that is remote from the first device and that executes a remote client application,
wherein the local server application, when executed, receives an event subscription request from the remote client application, the event subscription request specifying a target server application,
wherein the first device detects a local event at the first device, the local event being (i) associated with the event subscription request and (ii) one to which the remote client application is subscribed,
wherein the first device sends the event subscription request to a remote server application, which is remote from the first device, when the target server application is determined to be the remote server application, and
wherein the local server application executes within the local server application and on behalf of the remote client application, one or more server scripts associated with the local event, when a local event is detected.
