UXPin Merge is a revolutionary technology that lets users import (and keep in sync) coded React.js components from GIT repositories to UXPin editor (https://uxpin.com). The imported components are 100% identical to components used by developers during the development process. It means that components are going to look and, function (interactions, data) identical to the real product experienced by the users.

To make the first steps in the world of Merge easy, we've prepared this boilerplate repository with examples of components that shows the power of Merge:

• Configurable Button with multiple styling options
• Select with nested components
• Icon with access to dozens of SVG icons
• Table that automatically renders from a provided objects and adds sorting
• 5 animated charts created with React-vis library

All the components are built with React.js and styled with Emotion. Styles are using tokens stored in JSON files.

This boilerplate needs node and npm installed to run. Once you're ready clone the repository and install all the dependencies (npm install).

Merge Experimental Mode let's you render your React.js components in a dev version of UXPin Design Editor directly from your local environment. You can test your components and see how they're going to behave in UXPin Design Editor!

Among the dependencies of this boilerplate you'll find uxpin-merge this tool prepares components for integration with UXPin. It has a built in development server that you can use to see the rendered components in the browser. To start the dev server use the following command:

npm start

When you're changing anything in the components files and you want to re-render components, don't forget to kill the process. Otherwise you'll get a ELIFECYCLE error. A handy way to kill all the node processes including the dev server is to run in your terminal:

killall -9 node

This repository uses tests created with Jest-Emotion and Enzyme. To run all the test suites use:

npm test

When you're modifying components, you have to generate new snapshots:

npm test -- -u

Adding components to Merge is no different than creating normal React.js components. Merge accepts any standard approach to React. The only limitations that you should be aware of are:

• Components have to have default exports
• Components need to exist in separate directories
• Only one component is allowed per file and directory e.g. ./src/Button/Button.js
• You have to add the component to uxpin.config.js file
• You have to prepare presets for every component (temporary restrictions to be replaced by jsx presets)

Preset (to be replaced with JSX presets in the future) is a JSON file that describes components in a structured way.

• For ./src/Button/Button.js component we require one preset in ./src/Button/presets/0-default.json
• More presets can be added (not yet supported in the editor) by defining the sort index and readable name in the file name (for example: 100-Button with icon.json, 200-Icon Button.json).

Example preset:

{
  "rootId": "select548853352",
  "elements": {
    "select548853352": {
      "name": "Select",
      "props": {
        "width": 300,
        "children": [
          {
            "uxpinPresetElementId": "selectitem2379554241"
          },
          {
            "uxpinPresetElementId": "selectitem230242005"
          },
          {
            "uxpinPresetElementId": "selectitem1081055471"
          }
        ]
      }
    },
    "selectitem2379554241": {
      "name": "SelectItem",
      "props": {
        "children": "Option1"
      }
    },
    "selectitem230242005": {
      "name": "SelectItem",
      "props": {
        "children": "Option2"
      }
    },
    "selectitem1081055471": {
      "props": {
        "children": "Option2"
      }
    }
  }
}

As you can see at the top of the structure you need a reference to rootId. That can be any string, but to make things easier a good practice is to use name of the element and random integers (easier to read and assures uniqueness). Subsequently, under the elements key, you will list all the components that are going to be rendered in Merge. Every component has to be identified by a unique id (root component has to repeat the id inside of the elements key) and has to have a props key that lists all the properties (leave empty if component doesn't have any props – props: {}).

For components that have other components given as children (like the SelectItem component in the Select presented above) you have to create "uxpinPresetElementId" (just like for the root element) and use the id as a reference under elements id.

In case of components that accept other components via props other than children (like icon property in the Button below) you have to pass a JSX syntax as a property value:

{
  "rootId": "button4038267449",
  "elements": {
    "button4038267449": {
      "name": "Button",
      "props": {
        "stretched": true,
        "type": "error",
        "icon": "<Icon size=\"s\" icon=\"TickerSvg\"/>",
        "mode": "filled"
      }
    }
  }
}
