in the set-top box set, send it to him.Recent attention to node. JS, isn't that the feature of node NiO?Let's start with refactoring, using the innate advantages of node. js, high concurrency, non-blockingFirst, encapsulate the connection.VarMyClient=function(Client,Usernam

problem introduced a yarn.lock mechanism, this is the author of the project Yarn.lock file. Yarn.lock file formatAs you can see, this file has locked the version number of the dependent module, and when you do yarn install , yarn will read the file to get the dependent version number, and then follow this version number to install the corresponding dependent module, so that the dependency will be locked, no longer worry about the issue of the version number. Other people or other circumstances

Express is on the basis of node. JS, the development of a concise and practical framework structure, the use of this thing, we can more easily handle a lot of things. Just get started, it's a Beethoven! There are several ways to install Express in general. First, use NPM installation, cmd input NPM install EXPRESS-G, this-G is a global installation, that is installed in the folder you use "config set global

How does Nodejs use MySQL?To connect Nodejs to MySQL, you can use the MysQL driver of Nodejs. For example, here we use "node-mysql" to connect to the database. We use the following method to connect to the database:First, we need to use nodejs's package management tool (npm) to install the mysql driver. The command line is as follows:Npm install musqlNow, to use mysql in the js file, add the f

problem, here are just a few things we do: For files that specify several suffixes, add the Expires header and the Cache-control:max-age header in response. The timeout date is set to 1 years. Because this is a static file server, the last-modified header is returned for all requests, in response. For the request header with If-modified-since, make a date check, and if not modified, return 304. If modified, the file is returned. For the above static file server, the respon

In Java PHP or. NET, a new process is created for each client connection, and each process consumes about 2MVMemory, that is, theoretically a 8GB memory server can simultaneously connect the maximum number of users to 4000To allow the Web application to support more users, you need to increase the number of servers andThe cost of hardware for Web applications has certainly risen.NODE.SJ does not create a new thread for each client connection, but only uses one thread, and when a user connects, i

transmission process of leakage, there is only a possibility of brute force; AES has the advantage of grouping as a wheel, plus decryption speed is very fast, generally speaking, AES speed hundreds of times times the RSA So in real-world applications, we will mix AES and RSA, for example to encrypt a file that is not small in size, and might do this: Generates a one-time random key that encrypts a file using AES's CBC mode AES-256-CBC (encrypted packet 256-bit) After encry

This article mainly introduces NODE. the perfect solution for JS cross-origin problems is of great reference value. If you need a good solution, you can refer to the company's colleagues (front-end) who wrote the page over the past few days and always said they could not get the desired JSON, android iOS can get it, but he is also a newbie and doesn't know why he only knows JavaScript cross-origin problems,

I. Preface1:node.js is essentially a JS run environment written in C + + using the Chrome browser V8 engine2: Compared to JS no browser security restrictions, additional system-level API: File read and write, process management, network communications.3: There are many projects completed with node.

sourcemap We can change this behavior. Disable socket. io. js download Method 1: Pass in the control parameter serveClient value false during instantiation let io = require('socket.io')(app, { serveClient: false}) Method 2: Call the serverClient Function Let app = require ('HTTP '). createServer () let io = require ('socket. io ') () io. serveClient (false) io. listen (app) // Or io. attach (app) If the service is bound before the function is called

ObjectiveJust answered Segmentfault's previous brother's question, "asymmetric decryption error." This belongs to node. js in the security of the application, meet the same problem should be a lot of people, based on the answer to the question, here is a brief summary.The theoretical knowledge of asymmetric encryption can be referred to the author's previous arti

JS Database Chapter--mongoose ODM Introduction MongooseAlmost all languages have a native database connection driver, this we have learned on the last time, such as Java Jdbc,mysql-connector, but the actual development in order to pursue efficiency will not use the original connection, not always establish a connection, the last one, Our registration and landing each write a connection operation, at l
