I have a question about how to install Uglify or Uglify2 on Debian. I'm also wondering whether I have to install Node.js as well.
My main goal of asking this question is to minify all my CSS and .js files and gzip/compress them so that the page load on my website gets faster for visitors.
I was looking over the net for a step by step tutorial on how to do that, but got nothing handy so far.
Does any one know how to do that?
You install uglify-js with npm which comes from Node.js
Install the npm package (which depends on nodejs)
apt-get install npm
Install uglifyjs
npm install --global uglifyjs
Now you have uglify-js
$ uglifyjs --version
uglify-js 2.4.13
Alternatively you can download the Node.js linux binaries from the download page.
wget https://nodejs.org/dist/v4.4.5/node-v4.4.5-linux-x64.tar.gz
Then extract Node to somewhere of your choosing
tar -C /opt -xvzf node-v4.4.5-linux-x64.tar.gz
export PATH="$PATH:/opt/node-v4.4.5-linux-x86/bin"
Or install Node system-wide
tar -C /usr/local --strip-components 1 -xvzf node-v4.4.5-linux-x64.tar.gz
clone the repository
mkdir -p /where/you/wanna/put/it
cd /where/you/wanna/put/it
git clone git://github.com/mishoo/UglifyJS.git
make the module available to Node
mkdir -p ~/.node_libraries/
cd ~/.node_libraries/
ln -s /where/you/wanna/put/it/UglifyJS/uglify-js.js
and if you want the CLI script too:
mkdir -p ~/bin
cd ~/bin
ln -s /where/you/wanna/put/it/UglifyJS/bin/uglifyjs
(then add ~/bin to your $PATH if it's not there already)
