Preface
Presumably, we should use Node. js most to create http services. Therefore, for every Web Development Engineer,
When we use PHP to write background code, we need to use Apache or Nginx HTTP server, with MOD_PHP5 modules and php-cgi.From this perspective, the entire "Receive HTTP request and provide Web page" requirement does not need PHP to handle at all.But for node. JS, the concept is completely different. When using node.
This article mainly introduces Node. in js, the event transmitter mode is used to implement event binding. This article also explains the basic knowledge of callback mode, transmitter mode, and event type. For more information, see Node, many objects launch events. For example, a TCP server will launch a "connect" even
Node. js builds local servers to easily solve cross-origin problems. node. js local servers
Recently, I used a demo written with jquery to run it. At the beginning, I forgot to enable the local service. As a result, the console always reported XMLHttpRequest cannot load file: // C: /Users/79883/Desktop/ajax/data. json?
After you install node. js, choose a beneficial IDE for your development.After comparing multiple Ides, it is positioned on webstrom and sublime.There is a simple comparison:Webstorm feature is very rich, the front-end development tool of the synthesizer, compared to sublime slightly heavierSublime plug-in is also very rich, the interface is more beautiful, very light, also has a simple project management f

Exception capture in Node. js callback Functions
Node. js has many asynchronous APIs, which are processed by the callback function callback. If an error occurscallbackThe first parameter of the function containsErrorObject. If no error occurs, the first parameter isnull. For example:
