librarie.js

Reusable lightweight library component based on React.js

Set up

Installing all dependencies

$ npm install

Note: If you are having trouble running npm install and are outside the adsk network, please try removing the .npmrc file.

Build and run librarie.js

Build source scripts

$ npm run build

Both librarie.js (development script) and librarie.min.js (production script) will be output in ./dist/ folder. By default librarie.min.js will be referenced in index.html.
Serve up the new library view

$ node ./index.js
Navigate to localhost:3456 in Google Chrome browser

Run Tests

Run all tests

`$ npm run test`

Test file is at folder `./__tests__/`

Run test for utility functions

`$ npm run utiltest`

Test file is at `./__tests__/mochatest/libraryUtilitiesTest.ts`

Run all tests command does run all the tests, but it does not output libraryUtilitiesTest.ts console messages. When any test fail, it is unclear which one does and why. When that happens, use the command above to run just the utility tests.

Example test

   // Importing the object to be tested
    import { LibraryItem } from '../src/components/LibraryItem';

   // A test case that tests object properties against their intended value 
    it("should create a libraryItem", function () {
    let libContainer = libController.createLibraryContainer(layoutSpecsJson, loadedTypesJson);
    let libraryItem = mount(<LibraryItem libraryContainer={libContainer} data={data} />); 
    expect(libraryItem.props().data.childItems[0].text).to.equal("Child0"); 
   }

Usage

There are few ways in which library view (i.e. LibraryContainer object) can be constructed. Regardless of which method is used, the caller should first call LibraryEntryPoint.CreateLibraryController method to create LibraryController before obtaining an instance of LibraryContainer object.

    <script>
        let libController = LibraryEntryPoint.CreateLibraryController();
    </script>

Method 1

Constructing library view given the ID of an existing HTML element:

    <div id="libraryContainerPlaceholder"></div>
    <script>
        let libController = LibraryEntryPoint.CreateLibraryController();
        let libContainer = libController.createLibraryByElementId("libraryContainerPlaceholder",
            loadedTypesJsonObject, layoutSpecsJsonObject);
    </script>

LibraryController.createLibraryByElementId function takes the following values as its arguments:

htmlElementId - The ID of an HTML whose content is to be replaced with LibraryContainer.
loadedTypesJsonObject - The JSON object to be used by library view as Loaded Data Types. This argument is optional, but if it is supplied, the corresponding layoutSpecsJsonObject must also be supplied. If this argument is not supplied, see Method 2 below for details on how it can be supplied at a later time.
layoutSpecsJsonObject - The JSON object to be used by library view as Layout Specification. This argument is optional, but if it is supplied, the corresponding loadedTypesJsonObject must also be supplied. If this argument is not supplied, see Method 2 below for details on how it can be supplied at a later time.

Method 2

Constructing a library view for consumption by other React.js components (e.g. hosting the library within a React.js tab control). This method creates a valid JSX.Element object so that it can be directly embedded under another React.js element. For details of loadedTypesJsonObject and layoutSpecsJsonObject, please refer to the above section.

    <script>
        let libController = LibraryEntryPoint.CreateLibraryController();
        let libContainer = libController.createLibraryContainer();

        let aReactJsTabContainer = ...;
        aReactJsTabContainer.addTabPage(libContainer);

        // Supply loaded types and layout specs at a much later time.
        let append = false; // Replace existing contents instead of appending.
        libController.setLoadedTypesJson(loadedTypesJsonObject, append);
        libController.setLayoutSpecsJson(layoutSpecsJsonObject, append);
        libController.refreshLibraryView(); // Refresh library view.
    </script>

Sample usage of librarie.js

The following simple HTML code illustrates the way to embed library view into an existing web page.

<!DOCTYPE html>
<html>
    <head>
        <style>
            body {
                padding: 0;
                margin: 0;
                background-color: #353535;
            }
        </style>
    </head>
    <body>
        <!-- This is where the library view should appear -->
        <div id="libraryContainerPlaceholder"></div>

        <!-- The main library view compoment -->
        <script src = './dist/librarie.min.js'></script>

        <!-- Initialize the library view component -->
        <script>
            // Through client specific logic download json objects
            let loadedTypesJsonObject = getLoadedTypesJsonObject();
            let layoutSpecsJsonObject = getLayoutSpecsJsonObject();

            let libController = LibraryEntryPoint.CreateLibraryController();

            libController.on("itemClicked", function (item) {
                console.log(item); // Subscribed to click event
            })

            let libContainer = libController.createLibraryByElementId(
                "libraryContainerPlaceholder", // htmlElementId
                loadedTypesJsonObject,
                layoutSpecsJsonObject);

        </script>

    </body>
</html>

Registering event handlers

LibraryController object supports several events. So subscribe to an event of interest, do the following:

// 'libController' is an instance of 'LibraryController' previously constructed. 
libController.on("someEventName", function(data) {
    // Handle 'someEventName' here, the argument 'data` is event dependent.
});

The event names are also defined as string properties in the controller.

Event 'itemClicked'

This event is raised when a library item is clicked. The registered event handler will be called with the following argument:

contextData: This is the value of contextData passed through Loaded Data Types JSON data for the corresponding item.

libController.on("itemClicked", function(contextData) {
    console.log(contextData);
})

The string property for the event name is: ItemClickedEventName. So the following achieves the same:

libController.on(libController.ItemClickedEventName, function(contextData) {
    console.log(contextData);
})

Event 'searchTextUpdated'

This event is raised when user starts typing on the search bar, and the display mode of SearchView is list. In this event, it should call a search algorithm from some other components, and return a list of Search Result Items in JSON format to the caller.

searchText: This is the value of state searchText in SearchView component, which is a string value that user has entered in the search bar.

libController.on("searchTextUpdated", function (searchText) {
   console.log(searchText);
   return null;
});

The string property for the event name is: SearchTextUpdatedEventName. So the following achieves the same:

libController.on(libController.SearchTextUpdatedEventName, function(contextData) {
    console.log(contextData);
})

Event 'itemMouseEnter'

This event is raised when the mouse enters the range of one library item.

libController.on("itemMouseEnter", function (arg) {
   console.log("Data: " + arg.data);
   console.log("Rect(top, left, bottom, right): " + arg.rect.top + "," + arg.rect.left + "," + arg.rect.bottom + "," + arg.rect.right);
});

The string property for the event name is: ItemMouseEnterEventName. So the following achieves the same:

libController.on(libController.ItemMouseEnterEventName, function(arg) {
    console.log("Data: " + arg.data);
    console.log("Rect(top, left, bottom, right): " + arg.rect.top + "," + arg.rect.left + "," + arg.rect.bottom + "," + arg.rect.right);
})

Event 'itemMouseLeave'

This event is raised when the mouse leaves the range of one library item.

libController.on("itemMouseLeave", function (arg) {
    console.log("Data: " + arg.data);
    console.log("Rect(top, left, bottom, right): " + arg.rect.top + "," + arg.rect.left + "," + arg.rect.bottom + "," + arg.rect.right);
});

The string property for the event name is: ItemMouseLeaveEventName. So the following achieves the same:

libController.on(libController.ItemMouseLeaveEventName, function(arg) {
    console.log("Data: " + arg.data);
    console.log("Rect(top, left, bottom, right): " + arg.rect.top + "," + arg.rect.left + "," + arg.rect.bottom + "," + arg.rect.right);
})

Event 'itemSummaryExpanded'

This event is raised when user clicks on the expand icon displayed on the right of a leaf library item or search result item. This event should return data for showing summary, which contains inputParameters, outputParameters and description, follwing the format in the example below.

arg: This contains a callback function setDataCallback and contextData of the item. The function setDataCallback will send the data back to librarie.js for displaying ItemSummary.

libController.on(libController.ItemSummaryExpandedEventName, function (arg) {
    var data = arg.contextData;

    // The final data sent back to librarie.js should follow the format in the example.
    var finalData = {
        "inputParameters": [
            {
                "name": "c1",
                "type": "Color"
            },
            {
                "name": "c2",
                "type": "Color"
            }
        ],
        "outputParameters": [
            "Color"
        ],
        "description": "Construct a Color by combining two input Colors."
    };

    // Send data back to librarie.js
    arg.setDataCallback(finalData);
});

Event 'sectionIconClicked'

This event is raised when used clicks on the icon displayed on the right of a section header.

sectionText: This is the text property of the section that is clicked, which is defined in the Layout Specification.

libController.on(libController.SectionIconClickedEventName, function (sectionText) {
     console.log(sectionText, "icon clicked");
     return null;
});

Overriding the default search function

The default search function can be overriden by setting searchLibraryItemsHandler of the controller.

libController.searchLibraryItemsHandler = function (text, callback) {
}

text: This is the input string for searching.
callback: This is defined as SearchLibraryItemsCallbackFunc. It need to be called with the search result in a json format as defined in https://github.com/DynamoDS/librarie.js/blob/master/docs/loaded-data-types.md.
