This example is deprecated in favor of a new Node.js Application and Layout Server Example.

Glue42 Desktop can store layouts locally or use a REST service as a store. This package contains a simple REST server that operates as a layouts store.

This basic implementation stores the user layouts in files (they have the same structure as the local layouts files) and returns the same set of data for all users (does not take the user into account). New layouts are stored in files (using the name of the layout - there is no validation whether the layouts name can be used as a filename). The remove layout operation is not implemented and just logs to the console.

In order to run the layouts server, you need to install npm and Node v.10 (probably can run with a lower one as well).

Navigate to the server root directory and run from a command prompt:

npm i
npm run start

The layouts server will start to listen on port 8004 and will load layouts from the \layouts folder. The environment variable SERVER_PORT can be used to override the default port and the default layouts folder can be changed by setting the LAYOUTS_FOLDER variable.

If your Glue42 Desktop copy is not configured to load layouts from a REST service, you need to edit the system.json file located in the %LocalAppData%\Tick42\GlueDesktop\config folder.

1. Locate the layouts top-level property:

 "layouts": {
    "store": {
        "type": "file"
    }
  }

2. Update the layouts store to:

 "layouts": {
    "store": {
        "type": "rest",
        "restURL": "http://localhost:8004/",
        "restFetchInterval": 20
      }
  } 

• type - can be file or rest, depending on the type of layouts store you want to setup;
• restURL - the URL address of the layouts REST service;
• restFetchInterval - interval (in seconds) for fetching layouts from the REST service;

The REST service implements:

• GET layouts - returns all layouts. In a real implementation this should consider the user that is passed in the request headers.
• POST layouts - creates/updates a layout in this demo server;
• DELETE layouts - removes a layout. Does nothing in this demo server, only logs to the console;
