Technical Field
The invention relates to the field of message reminding, and particularly provides a message reminding system and method based on nodejs.
Background
Nodejs is a JavaScript runtime environment for the Chrome V8 engine. Nodejs uses an event-driven, non-blocking I/O model.
Node is a development platform for operating JavaScript at a server, and the JavaScript becomes a scripting language which is flush with the languages of the server such as PHP, Python, Perl, Ruby and the like. Published in 5 months of 2009, developed by ryan dahl, essentially encapsulating the Chrome V8 engine.
Node optimizes some special cases and provides alternative API, so that V8 can operate better in non-browser environment. The V8 engine executes Javascript very fast and has very good performance. Node is a platform established based on ChromeJavaScript operation and is used for conveniently establishing network application with high response speed and easy expansion. Nodes use an event-driven, non-blocking I/O model to be lightweight and efficient, and are well suited to running data-intensive real-time applications on distributed devices.
At present, for message reminding in a system, an interface is mostly called to store a message in a database, then a page is started to cycle, and an inquiry interface is called repeatedly, so that a message reminding service is achieved.
