node js reporting engine

The emerging node. js has attracted a lot of developers, providing us with a platform to quickly build high-performance network applications. I also began to gradually invest in node. in the embrace of JS, I encountered some problems and some experience in the process of learning and using. I think it is necessary to w

(Note: Ayo.js Fork from node. js.) Currently, a large number of documents still point to the node. JS Library. ）Ayo.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. Ayo.js uses an event-driven, non-blocking I/O model to make it lightweight and efficient. Th

Node. js development-HTTP file server, The HelloWorld example is only for demonstration purposes. Here is an actual example: file server. We use Node. js to create an HTTP File Server.

IntroducedAs we all know, node. js runs on Chrome's JavaScript runtime platform, and we call that platform an elegant V8 engine. Both the V8 engine and the later node. JS are run in a single-threaded fashion, so the maximum perfor

node. JS relies on the V8 engine and the V8 engine is a JavaScript virtual machine written by Google for the Chrome browser. From the beginning, V8 's main goal was to make JavaScript run faster, or at least faster than its competitors. This is not easy for high dynamics. This section is about the evolution of V8 and

This article describes how to use the ejs template and jade template in a node jsexpress framework project. For more information, see some projects, for example, if you take over a project from someone else and you don't want to use egg JS or jade. If you do not want to rewrite the previous page, you may need to introduce an ejs or jade module. You only need to perform the following two steps to use the two

, and the HTML5 Web Workers API provides engine (spec) support for more complex process controls. Similarly, if you are using an event-based model to architect a Web application, your program may have at least 100 more scenarios that require threading support.Eventually you will find that your programming ideas and the way you think about them have changed, and your attention will be placed on the logic of the server-side processing requests without c

course, if the page structure is complex and the regular expression is very complex, especially after using the class libraries/crawler libraries that support xpath, it will be found that this method, although the entry threshold is low, however, scalability and maintainability are all odd. In this case, we recommend that you use some existing crawler libraries, such as xpath and multi-thread support. 2. for targeted crawling, the main goal is to parse the content dynamically generated by

of settimeout and SetInterval, node. JS also provides: Process.nexttick and setimmediate.Process.nexttick can then trigger the callback function before the current "execution stack" tail-the next event Loop (the main thread reads the "Task queue"). That is, it specifies that the task always occurs before all asynchronous tasks.Setimmediate adds an event at the end of the current task queue, and the task it

this way, the process of your server will not be idle waiting. In theory, there is no limit to the number of database queries at the same time, as well as the number of requests from users. The server responds only when there are events on the user's side, which is event-driven. FriendFeed is a python-based non-blocking framework tornado (which is known to also use this framework) to implement the new features described above. However, node.

within a scope, and submenu is a variable defined within the NG-REPEAT directive.With this processing, when the user clicks on a menu, it invokes the SetContent method in the Admin.js to change the content value. This change, in turn, affects the HTML effect, changing the content displayed in the lower-left area of the admin page. In the example, when you click on user management, a landing page is displayed.The code that contributes to this effect is as follows:The above code uses the ng-inclu
