best way to learn node js

, and the HTML5 Web Workers API provides engine (spec) support for more complex process controls. Similarly, if you are using an event-based model to architect a Web application, your program may have at least 100 more scenarios that require threading support.Eventually you will find that your programming ideas and the way you think about them have changed, and your attention will be placed on the logic of the server-side processing requests without c

Webpack implements hot replacement of Node. js code and webpacknode. js Gitter asked this question over the past two days, asked on Twitter, and asked on GitHub, but did not respond in the past two days.I didn't know the contact information of the author of Webpack because the jlongster who wrote the blog ignores me.The last message sent to Gitter seemed to have

I've been interested in learning more about node. JS recently. This is a server-side programming of the Java platform that allows developers to write Java code on the server, and many CentOS users are trying to learn the language's development environment. This is exactly what I want to do with this tutorial.First, make sure you have CentOS 7. Because it is the o

concurrency important? Node is really good at dealing with these two problems; How big is the project? Small project is not a problem, if it is a large project should be carefully evaluated (available libraries, repair a bug required resources, or both upstream, etc.) "Can I access the DOM in node?" "This is a good question! The answer is no, Dom is a browser thing, but fortunately node's

10 comparison challenges for PHP and node. js In the recent sitepoint of PHP vs node. js SmackDown, Craig Buckler compares the two languages on how to respond to a series of 10 challenges to determine which is better overall. These comparisons are always contradictory, Craig says in his book. As an interesting follow

Mongoose said so much, a lot of detailed usage, use the time Reference API documentation, most APIs are provided with sample code snippets. Other articles: Get started with node.

On the winform side, tree menus are very useful and convenient, so I want to put a tree menu on the page. I chose the dtree tool. There are still many ways to implement the page tree menu on the network. However, I think this tool is easy to use, and the configuration is relatively simple and can be used quickly. Dtree is pure js, so you do not need to import the jar package, and the configuration only needs to be configured in

or back end is the focus of the time, but how cooperation will be an issue in the context of multiple cross-field tasks.The event callback in node is a feature of node, and he solves the problem that the callback function is the best way to accept the return data of an asynchronous call, (many older programmers can't accept it), that the code is written in a seq

way, Users.js almost all rewritten. Let's take the Authenticate method as an example to explain. First look at the original authenticate:function authenticate(userName, hash){ for(var i = 0; i This is a typical synchronization method, simple and straightforward, traversing array comparisons. And look at the new authenticate:function authenticate(userName, hash, callback){ if(!User){ callback(2); return;} var query = User.findOne().where(‘name‘, us

fin, sends an ACK to the client, confirms that the serial number is received sequence number +1, the server enters the close_wait state.Third wave: The server sends a fin to shut down the server-to-client data transfer, and the server enters the Last_ack state.Fourth wave: After the client receives fin, the client enters the TIME_WAIT state, then sends an ACK to the server to confirm that the sequence number is received sequence number +1, the server enters the close state and completes four wa

install npm-gfThe first one is that there is no prompt for the settings. The second step will go to github to download npm files and progress, and the fourth step is to install npm to node. js will copy several cmd files and the mode_modules folder to the nodejs directory.In this way, npm is configured.If you need to install any modules, enter npm install ***.If

the background. Basically, all listener event objects (all instances of Eventemitter) support asynchronous interaction events, and you can interact with blocking code in this way, such as using files,sockets or sub-processes, which are eventemitters in node. js. [Multi-core] [8] This method can also be used, see: Node

languages. Craig determined that this round of Node won. Bruno: I disagree very much. There are some strange examples in the PHP syntax, many of which have been fixed, and many of them will be removed in the new version. On the other hand, JS also has the "this" problem ~ I disagree with bullet 3 (you do not need to switch between client development and Server development when using

exported object of the current module. For example, the module export object is a normal object by default and can be used in the following way if you want to change to a function. module.exports =function() {console.log(‘Hello World!‘);}; In the above code, the module default export object is replaced with a function.Module initializationThe JS code in a module is executed
