How to modify the image in nodejs

When using Node.js, installing dependent packages often requires access to foreign npm official sources. Due to network reasons, the installation package may be very slow or the installation may fail. To do this, we need to set the npm mirror source to a domestic mirror to increase download speed.

1. npm mirror address

Address	Website
cnpmjs.org	http://r.cnpmjs.org
Alibaba Cloud Mirror	https://developer.aliyun.com /mirror
Taobao NPM Mirror	https://npm.taobao.org/mirrors/npm

2. How to modify the npm image

1. Modify the npm image in the command line

Enter the following command in the terminal:

npm config set registry https://registry.npm.taobao.org

In the above commandhttps://registry.npm.taobao.org is the Taobao NPM mirror address. Using this address can greatly speed up the download speed of the Node.js module.

If you want to change the set mirror address back to the default official address, you can enter the following command:

npm config set registry https://registry.npmjs.org

2. Use cnpm

in the command line window Execute the following command to install cnpm:

npm install -g cnpm --registry=https://registry.npm.taobao.org

As mentioned above, the --registry=https://registry.npm.taobao.org parameter indicates using the Taobao NPM mirror source for installation. When using cnpm to install the module, no other settings are required. Just use cnpm install to automatically use the Taobao NPM mirror source.

3. How to check the npm mirror address

Enter the following command in the command line:

npm config get registry

The current npm mirror address will be output:

https://registry.npm.taobao.org/
