Get started with uglifyjs

Install node first, and go to the command line to check whether node and NPM are correctly installed.

 

Next, install uglifyjs. The command is as follows: NPM install uglify-js-G

 

Finally, do not forget to add node and NPM to the environment variables.

C: \ Program Files (x86) \ nodejs \;

C: \ Users \ taozhou \ appdata \ roaming \ NPM;

 

Now you can use uglifyjs to compress it, as shown in figure

Uglifyjs Folder/DOM. js-> Folder/dom-min.js

 

Will compress Dom. js under the directory folder and save it in the same directory.
