Node.js: V12.16.1 (64-bit)

Download and install

1. Introduction to Node.js

Node.js is a platform built on the Chrome JavaScript runtime. Node.js is a non-blocking, event-driven I/O server-side JavaScript environment based on Google’s V8 engine, which executes JavaScript very fast. Very good performance.

Event-driven: The server responds only when an event occurs on the user’s side

Non-blocking: Node.js applications are developed in javascript and run directly on Google’s perverted V8 engine. With Node.js, you don’t have to worry about client requests running through a block of code on the server. Think of a non-blocking server as a loop that runs forever. When a new request comes in, the loop picks it up, passes the request to another process (such as a database query process), and responds with a callback. When it’s done, the loop continues to run, taking other requests. So let’s go like this. The server will not wait for the database to return results as it did before.

Node.js official website

Nodejs.org/en/download…

3. Download the node.js version of the local operating system

4, installation,

Once the file is downloaded, double-click the.msi file to install it, and keep clicking Next. Note: Install nodejs in the develop folder on drive D:\ develop \

Note the following screenshots:

'NPM Package Manager' stands for NPM package manager 'online Documentation Shortcuts' Add to PATH' Add node installation PATH to environment variablesCopy the code

After the installation is complete, node.exe has been added to the system environment variable path by the installation package in.msi format. If not, you need to manually add it (choose System variable > Path variable name > Edit path to add Node), as shown below:

5. Test whether the installation is complete

Windows+R, enter CMD, run CMD: node -v (there is a space between node and v)

The installation is complete as shown in the figure

The installation directory is as follows:

** New versions of Node.js come with NPM, which is installed with node.js when installed. NPM is used to manage node.js dependent packages

6. Introduction to NPM

NPM is a package management tool for Node.js, which can solve many problems in node code deployment. Allow users to download third-party packages written by others from NPM servers for local use; Allows users to download and install command line programs written by others from the NPM server for local use. Allows users to upload their own packages or command-line programs to the NPM server for others to use.

Three, environment configuration

1. The environment configuration here is mainly to configure the path of the global module installed by NPM, and the path of the cache cache. The reason for the configuration is that the implementation of similar in the future: NPM Install Express [-g] (optional -g, g indicates the global installation), the installed module will be installed in the [C: Users\ User name \AppData\Roaming\ NPM] path, occupy disk C space.

2. Create two empty folders [node_global] and [node_cache] in node.js folder, as shown below:

Use the following command to configure the NPM global module directory and cache directory to the two directories we just created

npm config set prefix "D:\\Develop\\nodejs\\node_global"

npm config set cache "D:\\Develop\\nodejs\\node_cache"
Copy the code

3. Set environment variables

“My Computer” – right-click – “Properties” – “Advanced System Settings” – “Advanced” – “Environment Variables”

Create a new NODE_PATH under system Variables and type D:\Develop\nodejs\node_modules

Change Path to D:\Develop\nodejs\node_global

4. Check whether the test environment is configured

After the configuration, install a Module test, we will install the most commonly used Express module, open CMD window, enter the following command to install the module globally:

NPM install express -g # -g
