Node. js static server implementation method, node. js static Server When you enter a url, the url may correspond to a resource (File) on the server or a directory. The So server analyzes the url and does different things for different situations. If the url corresponds to a file, the server returns the file. If the ur

, Node. js is single-threaded. Based on this, the synchronization code will block the entire application. For example, most file system APIs have their synchronization versions. The following code demonstrates two operations: synchronous and asynchronous: The Code is as follows: // AsynchronousFs.readFile('file.txt ', function (err, buffer ){Var content = buffer. toString ();}); // SynchronousVar content =

This article mainly discusses and verifies whether forEach () in node. js is synchronous or asynchronous, and shares ideas and methods with you. if you need it, you can refer to it. Almost all callback functions in node are asynchronous. the code behind the callback function may be executed before the code in the callback function is executed, especially for data

required for BT download and the settings for the Tracker server. The file information is generated based on the calculation of the target file, the calculation result is encoded according to the Bencode rules in the BitTorrent protocol. The main principle is to divide the downloaded files into equal blocks, which must be an integer of 2 K to the power of 2 k (because it is a virtual block, files are not generated on the hard disk), and the index information and Hash Verification Code of each b

By default, the transmission process of Nodejs read/write stream is transmitted in the form of buffer, unless you set other encoding formats for it. For details, refer. The stream in Node. js is very powerful. It provides support for processing potential large files and abstracts data processing and transmission in some scenarios. Because it is so easy to use, we often write some tool functions/libraries ba

. Libuv also provides an abstract pthreads-like thread for more complex Asynchronization. Node. js C/C ++ extensions must go beyond standard event loops. The plug-in authors encourage them to think about how to avoid blocking the I/O Event loop and perform task-intensive work through libuv non-blocking system operations, working threads, and custom threads. • Node
