Workspace Controller

import { createWorkspaceController } from "@equinor/workspace-core"
const workspaceController = createWorkspaceController();

The workspace controller is a common hub for all controllers. The idea is for the workspace controller to be pure JS/TS and not be dependent on any JS framework. The Workspace controller will consist of the followings sections.

Controllers

A collection of building blocks allows the creation of a workspace. And the building blocks themselves are interchangeable and will be customized toward the workspaces needs. Controllers are the actuators of the workspace; nothing happens without a controller. The goal is to create many small and specific controllers that do one thing well. To add a controller use the addController function on the workspace controller.


const controller = {
    name: 'dataSource',
    controller: dataSourceController,
    config: (dc, ws) => {
        dc.onDataChanged(data) => {
          wc.setData(data);
        });
    },
};

const workspaceController = createWorkspaceController();

workspaceController.addController(controller)

Middleware

Controllers are supposed to be 100% decoupled from each other. Middleware is the translator that connects one or multiple controllers. When adding a controller a sort of middleware can be added to the config as shown above. This ensures that all controllers can be used standalone and ensures high flexibility with low complexity. The addMiddleware function allows you to do the same as the config but you only get supplied the workspace controller.

function myDataSourceMiddleware( ws) => {
        ws.controller.dataSource.onDataChanged(data) => {
          wc.setData(data);
        });
    };

workspaceController.addMiddleware(myDataSourceMiddleware);

This will do the same as when you registered the controller but middleware allows for extreme flexibility, having the whole workspace at your disposal.

Data

A workspace i driven by data has a data and filteredData field. to sett these use the corresponding setDataand setFilteredData functions. When data is has changed all callback registered ont the onDataChanged event is triggered. Same thing goes for onFilteredDataChanged.

Context

Reserved slot for the developer(you) to define and utilize. Most common use for it is to share data from one controller to another. Through context and middleware but can be used passed data inn to the context.

setContext

workspaceController.setContext((currentContext)=> ({
  ...currentContext,
  person: {
    name: "Tom",
    lastName: "Jones"
    age: 82
  }
}));

Click and onClick

To be abel to trigger events by click, this will trigger the onClick event on the workspace controller.


workspaceController.addController({
    name: 'dataSource',
    controller: dataSourceController,
    config: (dc, ws) => {
        dc.onDataChanged((data) => {
          wc.setData(data);
        });
        wc.onClick((e, ws) => {
          if (e.type === "updateData") {
            ws.setData(e.data);
          }
        });
    },
});

workspaceController.click({
  type: "updateData",
  data: [
    // some data...
  ]
});

Error

The workspace controller consists of the "Core" events that most controllers will depend on in some form. Core Workspace events are the following.

  • onError

Core Functions:

  • throwError

Controllers and middleware usually bind through workspace controller events. Alternatively, you can extend the workspace controller with common data fields through the controller's context property.

Here is an diagram of use se figure1:
