Build

To compile PhotoSwipe by yourself, make sure that you have Node.js, Grunt.js, Ruby and Jekyll installed, then:

1) Clone the repository

git clone https://github.com/dimsemenov/PhotoSwipe.git
2) Go inside the PhotoSwipe folder that you fetched and install Node dependencies

cd PhotoSwipe && npm install
3) Run grunt to generate the JS and CSS files in the dist folder and the site in the _site/ folder

grunt
Optionally:

Run grunt watch to automatically rebuild files (JS, CSS, demo website and documentation) when you change files in src/ or in website/.
Run grunt nosite to build just JS and CSS files (output is folder dist/).
Run grunt pswpbuild to build just JS files. Param –pswp-exclude allows to exclude modules, for example grunt pswpbuild –pswp-exclude=history will exclude history module.
Using PhotoSwipe?

If you’ve used PhotoSwipe in some interesting way, or on the site of a popular brand, I’d be very grateful if you shoot me a link to it.
