Graph project

AMF graph project general components and libraries, including API navigation and events.

This is a work in progress.

This library contains general purpose web components and libraries to support AMF based API projects. It contains definitions for components ecosystem events and API navigation.

Usage

Installation

npm install --save @api-client/graph-project

API data model

The navigation component works with @api-client/amf-store. Use the store to initialize the API. The store acts as a value provider for the component. When initialized, the component dispatches a series of DOM events handled by the store to read the data from the graph. The hosting application has to initialize the API and the graph before this element is inserted into the DOM.

import { AmfStoreService } from '@api-client/amf-store';

const store = new AmfStoreService(window, {
  workerLocation: './node_modules/@api-client/amf-store/workers/AmfWorker.js',
});
await store.init();
const graphModel = await readDataModelSomehow();
await store.loadGraph(graphModel);

The navigation element queries the store once it is attached to the DOM. YOu can manually refresh the state by calling the queryGraph() function. You can also use the apiId property / attribute as declarative was of refreshing the state. When the value change (presumably the id of the web/async API) it queries for the new data.

Endpoints sorting

By default the element renders paths for endpoints as they are declared in the API spec file. SOmetimes, however, you may want to create a tree structure from the API endpoints list. In such case set the sort attribute. The navigation then sorts the endpoints alphabetically and creates a view tree from endpoints. It may create a number of "virtual" endpoints which are the closest common paths between two endpoints.

For example, consider having the following endpoint paths structure defined in the API:

smartylighting/streetlights/1/0/event/{streetlightId}/lighting/measured
smartylighting/streetlights/1/0/action/{streetlightId}/turn/on
smartylighting/streetlights/1/0/action/{streetlightId}/turn/off
smartylighting/streetlights/1/0/action/{streetlightId}/dim

By default the navigation render these paths as declared. When using the sort option the navigation renders the following tree

smartylighting/streetlights/1/0
  /action/{streetlightId}
    /dim
    /turn/off
    /turn/on
  /event/{streetlightId}/lighting/measured

Navigation list filtering

When the filter option is set then the navigation renders the filter text input. The user can use this input to filter menu items by any string provided in this input. Each item (depending on the item) is passed through the filter and the element only renders items that contains the user query. For example, an endpoint is filtered by its path and name. Operation is filtered by the method and name. And so on.
