Current user

import React from "react";
import { Spinner } from "@equinor/fusion-components";
import { useCurrentUser } from "@equinor/fusion";

const MyComponent = () => {
    const currentUser = useCurrentUser();

    // Current user might not be retrieved from the cache when the component loads,
    // So check for nulL!
    if(currentUser == null) {
        return <Spinner />;
    }
    
    return (

Core resources

import React from "react";
import { Spinner } from "@equinor/fusion-components";
import { useCurrentContext, ContextTypes, useHandover, useHandoverMcpkgs } from "@equinor/fusion";

const MyHandoverCommpkgDetails = ({ id }) => {
    const currentProject = useCurrentContext(ContextTypes.PDP);
    const [isFetching, handoverMcpkgs] = useHandoverMcpkgs(currentProject, id);
    
    if(isFetching) {

            {handoverData.map(handoverItem => (
                <li>
                    <h2>{handoverItem.commpkgNo}</h2>
                    <MyHandoverCommpkgDetails id={handoverItem.id}  />
                </li>
            ))}
        </ul>
    );

export default MyComponent;

Core settings

Core settings are read-only for apps

import React from "react";
import { useCoreSettings, ComponentDisplayTypes } from "@equinor/fusion";

const MyComponent = () => {
    const coreSettings = useCoreSettings();

    if(coreSettings.componentDisplayType === ComponentDisplayTypes.Compact) {
        return (<span>Looks like you prefere compact mode!</span>);
    } else {
        return (<h2>Some more spacing for you!</h2>)
    }
};

export default MyComponent;

App settings

App settings are automatically scoped to the current app

import React from "react";
import { Button } from "@equinor/fusion-components";
import { useAppSettings } from "@equinor/fusion";

const MyComponent = () => {
    const [appSettings, setAppSettings] = useAppSettings();

    return (
        <Button
            primary contained
            onClick={() => setAppSettings("toggle", !appSettings.toggle)}
        >
            Click to toggle {appSettings.toggle ? "On" : "Off"}
        </Button>
    );
};

export default MyComponent;

Bootstrap the fusion core

import React, { useRef } from "react";
import { render } from "react-dom";
import { Router } from "react-router";
import { createBrowserHistory } from "history";
import {
    AuthContainer,
    createFusionContext,
    FusionContext,
    ServiceResolver,
} from "@equinor/fusion";

const serviceResolver: ServiceResolver = {
    getDataProxyUrl: () => "http://api.url.com",
    getOrgUrl: () => "http://api.url.com",
};

const start = async () => {
    const authContainer = new AuthContainer();

    // Handle redirect from login
    await authContainer.handleWindowCallbackAsync();

    // Register the main fusion AAD app (get the client id from config)
    const coreAppClientId = "{client-id}";
    const coreAppRegistered = await authContainer.registerAppAsync(
        coreAppClientId,
        [serviceResolver.getDataProxyUrl(), serviceResolver.getOrgUrl()]
    );

    if(!coreAppRegistered) {
        authContainer.login(coreAppClientId);
    } else {

        const Root = () => {
            const root = useRef();
            const overlay = useRef();
            const fusionContext = createFusionContext(

                serviceResolver,
                { root, overlay, }
            );

                    <FusionContext.Provider value={fusionContext}>
                        <div id="fusion-root" ref={rootRef}>
                            {/* The app component goes here */}
                        </div>
                        <div id="overlay-container" ref={overlayRef}>
                            {/* Leave this empty. Used for dialogs, popovers, tooltips etc. */}
                        </div>
                    </FusionContext.Provider>
                </Router>
            );
        };

        render(<Root />, document.getElementById("app"));
    }
};

start();

Hooks

useAbortableRequest

This hook will make an HTTP callback abortable, i.e allows for cancellation of a pending HTTP request. The HTTP callback in the example below is defined as executeRequest, which will make an HTTP request towards some API client. The callback will be made abortable when the callback is passed onto the useAbortableRequest hook, with the custom abort signal handler onAbort. E.g if the abortable callback onInput initiates a request, but the MyComponents component is unmounted, the initiated HTTP request will be cancelled.

export const MyComponents = () => {
    const {someClient} = useApiClients();
    const [state, setState] = useState();
    const [error, setError] = useState();
    const [loading, setLoading] = useState();
    const executeRequest = useCallback(async(e: Event) => {
        try{
            setLoading(true);
            const response = someClient.getFoo(e.target.value);
            setState(response);
        } catch (e) {
            setError(e.message);
        } finally (){
            setLoading(false);
        }
    }, [someClient]);
    const onAbort = useCallback(() => console.debug('request was aborted'));
    const onInput = useAbortableRequest(executeRequest, onAbort);
    return (
        <div>
            <input type="text" onInput={onInput} />
            <span>${state}</span>
        </div>
}
