gulp-haschanged-deps

Comparator function for gulp-changed to determine if any of the dependencies for a js module (amd, commonjs, or es6), sass, or stylus file has changed.

Example

var gulp = require('gulp');
var changed = require('gulp-changed');
var hasChangedDeps = require('gulp-haschanged-deps');

gulp.task('copy', function() {
  return gulp.src('public/lib/**/*')
    .pipe(changed('build/public/lib', {
      hasChanged: hasChangedDeps({
        allowMissingDeps: true
      })
    }))
    .pipe(gulp.dest('build/public/lib'));
});

The above example will only copy over files in public/lib if the file or any of it's dependencies are newer than the associated file in build/public/lib.

Options

• Setting allowMissingDeps to true (the default) will skip missing dependencies, however, if it's set to false and a dependency cannot be found, an error will be thrown.
• Setting precinct as an Object will be passed through to the Precinct library (which is what is doing all the heavy lifting behind the scenes). This can be helpful for setting a specific type of parser for finding dependencies. E.g. { precinct: { type: 'commonjs' } }.
