Nodejs There is no picture library, there will be later, but not now.Search the network for a lap, there are several solutions:1, the use of third-party verification code procedures, sometimes, the project may not be allowed;2, using Java or PHP to generate images, Nodejs call, the mi
I. node. JS: The javascript runtime environment on the server side. It features no blocking and event-driven features. It uses the V8 engine to implement web services similar to Apache and nginx, you can use it to build a javascript-based web app. Therefore, you need to know the following when developing with nodejs:1. How to run the nodejs server language (Interpreter) (similar to Python, you must install
Problem
GoDaddy last host can hang multiple sites (such as the PHP site), then node. js site can also be used as one of the sites on GoDaddy?
Virtual Host Implementation
To answer this question, we need to first analyze how the virtual host is implemented. Take Apache for example.In Apache server, the virtual host is supported by Apache itself (can view: https://httpd.apache.org/docs/current/vhosts/), only need to configure the Apache configuration file, You can put multiple sites on the same h

httpModule to start a local server, easy to debug.
It's probably like this:
varrequire("http");var server = http.createServer();server.listen(8888);
So the question is, how do I deploy my application to the VPS? You can't use it http://10.88.77.66:8888 to access it? Yes, the title of the article is the solution.

Let's first implement a simple example, hello world.
It seems that the first section of each language tutorial will talk about this, and we are no exception.
First, create a project directory, which can be defined by yourself. In this case, the directory is e:/nodetest /.

Reprinted from Http://www.searchsoa.com.cn/showcontent_79099.htmOver the years, node. JS has evolved into a mature development platform that has attracted many developers. There are many large, high-traffic sites that are developed using node. js, like PayPal, which developers can also use to develop some fast-moving web frameworks.In addition to Web applications, Nodejs is also used in many ways, and this article takes a count of the ten amazing proj

How does the module mechanism work?
Package Loading
First of all, it should be declared that JS does not have a module mechanism, which will inevitably cause a lot of trouble to create a substantive project. After all, our goal is, we still need to create a systematic, scientific, modern, and standardized logic code boundary. Otherwise, if it is a backward management mechanism, it is an obvious short board.
Nodejs first writing experiences and nodejs writing experiencesHow to view and install other tools after nodejs Installation

Preface
If we don't want to learn nodeJs, we will get old... when the HTML5 waves hit us, many of our predecessors started the NodeJs journey, and at that time I was still working on server-side programs.Later, it turned into a front-end, which is far away from the Echelon. Because I

So I followed Scott's teacher to learn the course of the

I. Preface
Nodejs has been used for a few days. Recently, I will review its API and use more new features in order to have a higher level of understanding. The summary of this API is different from the Chinese version alone, I will do more expansion and my own understanding. I hope it will help you, starting with the core

node. JS is a JavaScript run environment (runtime). It actually encapsulates the Google V8 engine. The V8 engine executes JavaScript very fast and performs very well.
node. JS optimizes some of the special use cases, providing an alternative API that allows V8 to run better in a non-browser environment.

About debugging
When we focus only on the front-end, we use F12, which brings us a sense of security and comfort.
But when we use NodeJs for background development, I have a nightmare.
But don't worry about Thailand. It is inconvenient to debug Node
First, the opening analysisHello everybody, Big Bear is coming again (*^__^*) hehe ..., I wrote a series of articles about JS (OOP and design mode) , the response is OK, in fact, this is also the biggest encouragement to me, so I decided I want to carry out JavaScript to the endPrepare to write a series of nodejs aspects of the article, a gradual, progressive, adhering to the idea is to re-thinking, more practice, Qinnengbuzhuo, your insistence.

When Nodejs is used, it is inevitable to reference third-party modules. Some of them are provided by Nodejs (for example, http, net ...), some are published on npm (for example, mssql, elasticsearch ...)
