OpenFin Layouts

Overview

The OpenFin Layouts Service delivers window management and layout user experience across the desktop for OpenFin-based applications.

This project consist of 3 parts:

1. The Layouts Provider, managing the state of windows and layouts
2. The Layouts Client, exposing APIs for applications to control snap & dock and save & restore
3. The Layouts Demo App, demonstrating the different features of OpenFin Layouts

Dependencies

• OpenFin version for applications using the Layouts Service = 15.80.49.30
• OpenFin version used by the Layouts Provider = 15.80.49.30
• RVM >= 4.7

Default Features

• Snap & Dock
  • Windows snap to all sides of other window or group of windows
  • Windows snapping to another window of similar size will resize to match the target window
  • Visible feedback on where a dragged window will be snapped/resized to
  • Resize windows in group
  • Windows can be undocked by pressing CTRL+SHIFT+U or CMD+SHIFT+U when the window has focus
  • Windows and groups can also be undocked using the client API
• Save & Restore
  • The service has APIs for generating and restoring workspaces
  • The provided demo showcases how a layout manager application could use the APIs to manage workspaces
• APIs
  • APIs available to undock, ungroup, save/restore workspaces, and opt-out of service functionality
• Hosting
  • The latest production version OpenFin Layouts will by default be served from OpenFin's CDN
  • For testing/development purposes, customers can specify an absolute version/location of the service by providing the full URL in the services section of the app manifest (see 'Manifest declaration' below)
  • To self-host versions of the service, each release is also deployed to the CDN as a zip file, available at https://cdn.openfin.co/services/openfin/layouts/<version>/layouts-service.zip

Depricated Features

• Tabbing
  • Note: This is not officially supported. Tabbing will only work when all tabbed windows are in the same runtime version as the layouts service provider and the monitor scaling is set to 100%. For documentation regarding opting into this feature please see the docs here
  • Dropping a window on-top of another window will tab the windows together
  • Dropping a window on-top of an existing tab group will add it to that group
  • Tabs can be reordered and renamed
  • Minimize/maximize/restore/close on the tabstrip affects the whole tab group (tabstrip and tabbed windows)
  • Application developers can provide their own tabstrip - simply by hosting a templated html file
  • The service comes with a Chrome-like default tabstrip that will be used if no custom tabstrip is defined

Getting Started

Integrating the Layouts Service within an application is done by declaring the service in the application manifest, and importing the Client API.

Manifest Declaration

To ensure the service is running, you must declare it in your application config.

"services":
[
   {"name": "layouts"}
]

During development, you can add a URL for specifying a custom location or a specific version:

"services":
[
   {
       "name": "layouts",
       "manifestUrl": "https://custom-location/<version>/app.json"
   }
]

Refer to the Desktop Services documentation for details on managing service location/version within production environments.

Import the Client API

npm install openfin-layouts

The client library is also available as a resource which can be included via <script> tag:

<script src="https://cdn.openfin.co/services/openfin/layouts/<VERSION>/openfin-layouts.js"></script>

This will expose the global variable layouts with the API methods documented in the link below. Example:

layouts.snapAndDock.undockWindow();

The client module exports a set of functions, documented in the API docs.

Usage

Using Layouts is described in detail in our tutorial.

Running Locally

To preview the functionality of the service without integrating it into an existing application - or to start contributing to the service - the service can be run locally.

Setup

After checkout, install project dependencies using npm install. The integration tests within the project rely on robotjs in order to manipulate windows at the OS-level. This adds some caveats to being able to follow the standard "npm install ; npm start" convention:

• Windows support only.
• Node 8.11 LTS.
• Installing the pre-requisites of robotjs.
  • A simple one-liner alternative is to use windows-build-tools, by running npm install -g windows-build-tools with Administrator privileges.

To setup the project whilst avoiding the above dependencies, install using npm install --ignore-scripts.

Startup

Once dependencies are installed, start the "built-in" sample application with npm start. This uses webpack-dev-middleware to both build and host the application; a custom server script will start the OpenFin application once the server is up and running.

The startup script has optional arguments which can be used to tweak the behavior of the build and the test server. Use npm start -- -h for details on the available parameters and their effects.

Build Process

The service consists of several different components unified into a single project. The package.json defines the combined dependencies of all components. Any modules required for the pre-built client to work within an application are included in the "dependencies" section, and the remaining dependencies - used to build the client, and to both build & run the provider and demo application - are included under "devDependencies".

Similarly, there is a single webpack.config.js script that will build the above components.

Testing

To run the full test-suite for layouts-service, run:

npm install
npm test

This will run unit tests followed by the integration tests. These steps can also be run individually via npm run test:unit and npm run test:int. When running the tests separately in this way, both test runners support some optional arguments. Append --help to either of the above npm run commands to see the available options.

Deployment

Staging and production builds are managed via the Jenkinsfile build script. This will build the project as usual (except with the --mode production argument) and then deploy the client and provider to their respective locations. The demo application exists only within this repository and is not deployed.

The service client is deployed as an NPM module, so that it can be included as a dependency in any application that wishes to integrate the service.

The service provider is a standard OpenFin application, only its lifecycle is controlled by the RVM (based upon the requirements of user-launched applications) rather than being launched by users. The provider is deployed to the OpenFin CDN; a zip file is also provided to assist with re-deploying the provider to an alternate location. Direct links to each build are listed in the release notes, available on the services versions page.
