Adding the Map Jig

Overview

In this section, there are two files to edit, namely, index.jigx and myfirstjig.jigx. In the index.jigx file, you configure the bottom navigation tab to display the myfirstjig.jigx on the Jigx mobile app Home Hub screen. In the myfirstjig jigx file, you will specify the default type of jig, assign an icon for the jig, and provide a static datasource that provides the location on the map.

See Jigx Concepts to learn what jigs are.

Steps

The Jigx Builder YAML editor includes code completion by simultaneously pressing the control and spacebar (ctrl+space) buttons. Only valid options in the current cursor context are displayed in the code popup.

Edit the index.jigx file

1. Click on the index.jigx file. This file is the menu structure of the app. In the index.jigx file you configure the navigation menu that displays at the bottom of the Jigx mobile app Home Hub screen.
2. Save the project.
3. Your index.jigx file should resemble the code below.

index.jigx

# The system name that uniquely identifies the solution
name: hello-jigx
# The friendly name of the solution
title: Hello-Jigx
# The built-in category selected for this solution
category: business
# The top-level navigation elements for jigs, displayed at the bottom of the app
tabs:
  home:
    label: home
    jigId: myfirstjig
    icon: home-apps-logo

Add the map to the jig

1. In Explorer expand the jigs folder and right-click on myfirstjig.jigx file and rename the file to map.jigx. Click to open the file, the Jigx auto-complete popup listing the five jig types displays. For this solution, we will be using the default jig to create the UI for displaying data. Click on Default to open the skeleton YAML created by the Jigx Builder.
2. Add Location with address as the title for your jig. The title appears under the widget on the Home Hub. Add a description for the jig, such as map with a marker.
3. On the line under type:, type icon:. To select an icon from the predefined list start typing the first two letters of the name of the icon, in this case lo, the list of icons starts to populate as you type. Select location from the list. This icon displays on the widget on the Home Hub.
4. Delete the header, and onFocus section, you will add a header later in the Combine the solution's elements section.
5. The map jig needs a datasource: defined that provides the location details. You will use a static datasource in this step. The static dataset is created directly inside the jig file of the Jigx solution, and there is no need to specify any database connections or set up any tables. The amount of records that can be created for the static data is unlimited and is used to bind data to the UI components.
6. Replace mydata: with address: press ctrl+space (Intellisense) and select Static Datasource.
7. Define the location details for the street, city and country under the data:tag. You can remove id:1. Add your own location or use the following as an example: 768 5th Ave, New York, US.
8. The controls displayed on the jig are defined under the children: node on a default jig. The output control is placed on the location component to display a map/location inside the jig. Under the children: node press (ctrl+space) and select Location from the list.
9. For the output control to display the map with the location you will use the address from the datasource using an expression to return the street, city and country to the location component. Next to options: press (ctrl+space) and select address from the list. To add the expression next to the address: line press (ctrl+space) and select =@ctx from the list. The root element of expressions in .jigx files always starts with "@ctx" vs. "$." in JSONata Exerciser (e.g. @ctx.data vs. $.data). Add the following to your expression: address: =@ctx.datasources.address.street & ',' & @ctx.datasources.address.city & ',' & @ctx.datasources.address.country
10. To ensure that the location marker can be seen on the map add a zoomLevel: 9 under the address line.
11. Save the project.
12. Your map.jigx file should resemble the code below.

map.jigx

# The system name that uniquely identifies the jig
title: Location with address
description: map with a marker
# The jig type used to display data
type: jig.default
icon: location

# The type of datasource used to return data in the jig
datasources:
  address: 
  # The static dataset is created directly inside the jig file
    type: datasource.static
    options:
      data:
        - street: 768 5th Ave
          city: New York
          country: US
# The control used by the jig to display a location          
children:
# The component location is an interactive map displaying the location using the address
  - type: component.location
    options:
      viewPoint:
        address: =@ctx.datasources.address.street & ',' & @ctx.datasources.address.city & ',' & @ctx.datasources.address.country
        zoomLevel: 9

Update the jigId in the index.jigx file

1. Click on the index.jigx.
2. Change the JigId from myfirstjig to map.
3. Your index.jigx file should resemble to the code below.

index.jigx

# The system name that uniquely identifies the solution
name: hello-jigx-solution
# The friendly name of the solution
title: Hello-Jigx Solution
# The built-in category selected for this solution
category: business
#The tab that act as top-level navigation elements for jigs
tabs:
  home:
    jigId: map   
    icon: location
