SyncY

One-way synchronization of directories with glob.

Install

$ npm i -S syncy

Why?

• Fast by using streams and Promises. Used cp-file and rimraf.
• User-friendly by accepting globs.

Usage

const syncy = require('syncy');

syncy(['src/**', '!src/folder/**'], 'dest')
  .then(() => {
    console.log('Done!');
  })
  .catch(console.error);

API

syncy(patterns, dest, [options])

patterns

• Type: string|string[]

Glob patterns that represent files to copy

dest

• Type: string|string[]

Destination directory or directories.

options

• Type: object

{
  // Display log messages when copying and removing files
  verbose: false,
  // Or create your own function.
  verbose: (stamp) {
    // action - `copy` or `remove`
    // to - only for `copy` action
    console.log(stamp.action + ' | ' + stamp.from + ' | ' + stamp.to);
  },
  // The base path to be removed from the path. Default: none
  base: 'base_path'
  // Remove all files from dest that are not found in src. Default: true
  updateAndDelete: true,
  // Never remove js files from destination. Default: false
  ignoreInDest: '**/*.js'
}

How to work with Gulp?

const gulp = require('gulp');
const syncy = require('syncy');

gulp.task('sync', (done) => {
  syncy(['node_modules/gulp/**'], 'dest')
    .then(() => {
      done();
    })
    .catch((err) => {
      done(err);
    });
});

How to work with Grunt?

const syncy = require('syncy');

module.exports = (grunt) => {
  // Default task(s).
  grunt.registerTask('default', function() {
    const done = this.async();
    syncy(['node_modules/grunt/**'], 'dest')
      .then(() => {
        done();
      })
      .catch((err) => {
        done(err);
      });
  });
};
