node. js buffer (buffer)The JavaScript language itself has only a string data type and no binary data type.However, when processing a TCP stream or file stream, you must use the binary data. Therefore, in node. js, a buffer class is defined that is used to create a buffer that is dedicated to storing the binary data.In

By default, the cache policy is enabled in IE. Both the page and the data requested by ajax meet a url. The url is an instance of the uri (Uniform Resource Identifier), and the url is the resource identifier.Write a demo for verification. Test environment: IE8, node. js 0.12.7, and the page template is jade.Page code: testCache. jadePlace a button on the page, cl

The Redis database adopts a simple design concept. The latest source code package is less than 2 Mb. Its usage is also different from the general database. The following article introduces how node. js uses the redis database to cache data. If you need it, let's take a look at it. The Redis database adopts a simple design concept.

In geek education, a video was published on "node. JS memory leak Analysis," This article focuses on how to handle node. JS memory anomaly issues from the content. If you wish to study, you can go to Geek College:Keywords in this

Basic knowledgeThe memory management of the node. JS process is automatically handled by V8, including memory allocation and deallocation. So when will V8 release the memory?Within V8, a graph is built for all the variables in the program to represent the association between

Server ({port: 9000 })Var client = new ws ('ws: // localhost: 9000 ')Client. on ('open', function (){Console. log ('open ')Client. ping (50) // this makes the server return a non-zeroed buffer of 50 bytesClient. on ('pong ', function (data ){Console. log ('got pong ')Console. log (data) // a non-zeroed out allocated buffer returned from t

Before we used node. JS on a 64-bit Linux server, when the node process physical memory approached 1.6G, the memory limitations of the Google V8 engine caused the process to exit!Obviously we have a memory leak problem with our ow

In this lesson, I introduce a memory leak into our node. js application and show how to identify it using the FORMIDABL E Nodejs-dashboard. Once identified, we'll add garbage collection stats to the error console allowing us to correlate garbage collection wit h The increased memory usage.Install:NPM i-d Gc-profiler No

This article mainly introduces what is Node. js? What are the advantages of Node. js ?, To try to explain what Node is. js, this article will briefly introduce some background information: the problem to be solved, how it works, h

The use of caching is ubiquitous in web and app projects. It is used to mitigate the impact of two time-consuming heihu on the user experience while minimizing the burden on the server: access to the disk network access (Original article, reprint please indicate the CSDN blog that has been transferred from Clement-xu.) ） Therefore, the introduction of caching is generally to reduce the number of these two visits. Due to the wide range of Internet project nodes, each

around the mouth. What it really means is that node. js is not a silver-bullet platform that will dominate the world of web development. Instead, it is a platform to meet special needs. You certainly don't want to use node. js to do CPU-intensive operations. In fact, using it for heavy computing is tantamount to disca

to the current context, such as var math = require ('Math ');2). module definition: Use the exports object to export methods or variables of the current module. A module object exists in the module. exports is actually a module attribute. In Node, a file is a module, and the "global variables" in the module are invisible to the outside. Only the attributes mounted on exports are public, such as exports. add = function () {}; exports. PI = 3.1415926;3
