FileSync synchronizes local file changes to mapped records in ServiceNow instances.

This enables ServiceNow developers to use their favorite integrated development environments (IDEs) and text editors like WebStorm and Sublime for editing JavaScript, HTML, Jelly and other code - without wasting time and interrupting development workflow copying and pasting code into a browser.

When a file changes within a configured root (project) folder, the parent folder and file name are used to identify the table and record to be updated.

Adding an empty file, or clearing and saving an existing file, refreshes the local file with the latest instance version, syncing from the instance to the local file. This is an easy way to populate your project folder with existing scripts related to your project.

Quick Start

Download and check out the video walk-through of installing, configuring and using FileSync.

Or, continue with the steps below.


Step 1. Ensure the JSON Web Service plugin is activated for your instance.

Step 2. Download and unzip into your desired install path, for example:

  • On Windows: c:\dev\tools\filesync
  • On Mac: /Applications/filesync

Step 3. Create a local folder structure for your project / source files. Project folders will be mapped to root folders in the app.config.json config file. The following example folder structure is mapped in the app.config.json settings section below:


Step 4. Edit app.config.json.

  • Review the app.config.json settings section below for guidance. Please read all comments.
  • Configure at least one root (project) folder to host, user, pass mapping. user and pass will be encoded and replaced by an auth key at runtime.
  • Note: You must restart FileSync any time you update app.config.json.


With installation and configuration completed, you can start filesync by executing the included batch/shell scripts:

  • On Windows, double-click: filesync.bat
  • On Mac, initially, right-click on filesync.command and choose Open. Subsequently, you can double-click to open.

This launches a console window where you should see log messages showing the starting configuration of FileSync. Do not close this window. This is what is watching for file changes. As you make changes to mapped files, you'll see messages logged showing the sync processing.

Verify everything works by adding an empty file corresponding to an instance record. You can do this from your editor or IDE, or open a new command shell:

On Windows, at a command prompt:

cd c:\dev\project_a
md script_includes
cd script_includes
copy nul JSUtil.js      <-- creates an empty file named JSUtil.js

On Mac, in Terminal:

cd /path/to/project_a
mkdir script_includes
cd script_includes
touch JSUtil.js

Adding the empty JSUtil.js file will cause FileSync to sync the (OOB) JSUtil script include to the file. Any changes to this local file will now be synced to the mapped instance.

The basic workflow is to initially create a script on ServiceNow (script include, business rule, ui script, etc.), then add an empty file of the same name (and mapped extension) to a mapped local folder.

FileSync does not currently support creating new records in ServiceNow by simply adding local files since there are additional fields that may need to be populated beyond mapped script fields. So, always start by creating a new record on the instance, then add the empty local file and start editing your script.

FileSync was built using Node.js, a platform built on Chrome's JavaScript runtime. Zipped distribution contents:

  • - this file, written in Markdown syntax
  • node.exe, node-darwin - Node.js runtime binaries
  • filesync.bat, filesync.command - Windows and Mac batch/shell scripts for starting FileSync
  • app.config.json - configuration file with mapping of folders to instances/tables
  • app.js - main application that watches for file changes
  • config.js - a module used to load and validate and app.config.json file
  • snc-client.js - a module that interacts with SN JSON Web Service to receive and send updates to instance
  • node_modules - folder containing 3rd-party node.js modules (from NPM) used to build app
