#gulp-path-to-animation

Synopsis

Use to generate scss files with predefined @keyframes animations by reading configuration of paths to be interpolated.

Why would you need this?

• Do you want to have smooth css animations you don't want to handle by java script?
• Do you need to pause them?
• Do you need to resize and keep the animated element's position?
• Do you want to write such animation manually? And rewrite them every time the client changes the design?
• Animations using translate instead of top/left positioning are considered as better performance and calculating translate movement manually could be painfully sometimes.

path-to-animation needs just a JSON file with animations paths you would need and it will interpolate them and create the file with predefined @keyframes animations you need.

Installation

npm install gulp-path-to-animation

Usage

var gulp = require('gulp');

// this module is for the sake of the example in order to rename the file we will create
var rename = require('gulp-rename');

var pathToAnimation = require('gulp-path-to-animation');

gulp.task('default', function() {
  // define which is your paths configuration file
  gulp.src('./animation-paths.json')
    // get the css content after some calculations
    .pipe(pathToAnimation({
      namespace: 'my-namespace',
      elementWidth: 100,
      elementHeight: 100
    }))
    // use gulp-rename to specify the name of the output file
    .pipe(rename({
      basename: 'output-file',
      extname: '.scss'
    }))
    // write it wherever you like
    .pipe(gulp.dest('./dist'));
});
