This article mainly introduces how to use Node. js to implement content sharding in HTTP206. Node. js is a JavaScript framework for servers. For more information, see Introduction In this article, I will describe the basic concept of HTTP status 206, and use Node.

Node. js network communication module implementation analysis, node. js Network Communication Preface Presumably, we should use Node. js most to create http services. Therefore, for every Web Development Engineer,

Node. js checks for updates using the command line tool, and node. js command line With the popularity of Node. js, it becomes easier to develop command line tools using Node.

) {var stream = fs. createReadStream (path); // read stream. pipe (res); // stream reading is delivered in pipe mode}); server. listen (0, 3000 ); 2. tempServer. js ==> temporary file Sever, intermediate cache layer, multi-client download Var http = require ('http'); var fs = require ('fs'); var sourceReadStream = fs. createWriteStream ("BigFile. iso "); // write stream var GrowingFile = require ('growing

any of the following actions: The readable stream is not yet pipe to any flow, adjustable. Pause () paused The readable stream is already pipe to the stream, remove all data event subscriptions, and call the. Unpipe () method to remove the relationship to the downstream flow CalmnessIn conjunction with the asynchronous nature of the stream, I can write an application that directly bridges the output of user A to the page of User B:Router.post ('/post ', function (req, res) {

, and local installation is not required. 3. create an Express project. 4. open package. json and edit the template engine. "Jade": "> = 0.0.1" changed to "ejs": "> = 0.6.0" After saving, switch to cmd and execute Npm installl Check the package. json in the current directory and automatically install the required extension. Node_modules is added to the site directory, which is the extension library file. I personally don't like express's built-in jade template engine, so I use ejs templates wit

of Node is the construction of high-performance, highly scalable Internet applications-because it can handle massive and high-throughput concurrent connections. Its working principle is quite interesting. The traditional network service technology generates a new thread for each new connection request. This new thread will occupy the system memory and eventually occupy all available

=== require. main ){Console. log ("Main module at current module ");}// Output result: the current module is the main module. // 2. js CodeVar name = "Dr. Sisi ";Console. log (name );Exports. name = name; // 1. js code:Var two = require ("./2.js ");Var two = require ("./2.js ");// Although it is referenced twice, only

This article mainly introduces Node. the event-driven programming in js is explained in detail. This article mainly describes theoretical knowledge, such as what is event-driven programming, What Is closures, and how closures help asynchronous programming, if you need it, you can refer to the traditional programming model. I/O operations are like a common local function call: The program is blocked before t

building high-performance, highly scalable Internet applications-because it handles massive and high-throughput concurrent connections.How it works is quite interesting. The traditional Network Service technology, is each new connection (request) will generate a new thread, this new thread will occupy the system memory, will eventually take up all the available memory. While

This article mainly introduces Node. stream in js. This article describes what Stream, pipe method, Stream classification, and Readable Stream status switching. For more information, see What is stream? When it comes to stream, it involves the concept of * nix: pipeline-In * nix, the stream is implemented in Shell as data that can be bridge through | (pipeline operator, the output (stdout) of a process can

Node. js static file server ultimate version, node. js static ultimate version First, I would like to thank github for providing the source code on github. Compared with last night's static file server, it is a little more complex and can learn a lot of new things. The Code contains a fs. stat function and the pipe fun

This article describes how to use the Client Session in Node. js programming. It is the basic knowledge of Node. js beginners. If you need it, you can refer to the static website for easy extension. You only need to cache all the data and do not need to consider combining st

What is node. js?Nodejs is a JavaScript toolkit for writing high-performance Web servers (for JS development service-side programs)Single-threaded, asynchronous, event-drivenFeatures: fast, memory-consumingA millions concurrency test on the web, which consumes 16G of memory

Node. js uses the Google Chrome V8 engine, which has good performance and provides many system-level APIs, such as file operations and network programming. Node. js is a comprehensive background runtime that provides many functions that can be implemented by other languages for Javascript. Today, let's take a look at N

This article mainly introduces Node. how to Use the domain module in js exception handling. The memory leakage problems are mentioned at the end of this article. It is worth noting that if you need a friend, you can refer to the domain module provided by NodeJS, it can simplify Exception Handling for asynchronous code. Before introducing this module, we need to f
