From 6d5a2eebb609da67239ea37d12d6b2d3bbfef76e Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Wed, 28 Oct 2020 16:41:53 +0100 Subject: ui: Do not clutter component tree with Redux connects This change refactors the frontend to use hooks for obtaining state within the Redux store as opposed to using Higher-Order Components (HOCs). This eliminates a lot of clutter in the components. --- .../src/containers/app/map/TopologyContainer.js | 19 ++++++++----------- 1 file changed, 8 insertions(+), 11 deletions(-) (limited to 'opendc-web/opendc-web-ui/src/containers/app/map/TopologyContainer.js') diff --git a/opendc-web/opendc-web-ui/src/containers/app/map/TopologyContainer.js b/opendc-web/opendc-web-ui/src/containers/app/map/TopologyContainer.js index de43a151..612ca41c 100644 --- a/opendc-web/opendc-web-ui/src/containers/app/map/TopologyContainer.js +++ b/opendc-web/opendc-web-ui/src/containers/app/map/TopologyContainer.js @@ -1,17 +1,14 @@ -import { connect } from 'react-redux' +import React from 'react' +import { useSelector } from 'react-redux' import TopologyGroup from '../../../components/app/map/groups/TopologyGroup' -const mapStateToProps = (state) => { - if (state.currentTopologyId === '-1') { - return {} - } +const TopologyContainer = () => { + const topology = useSelector( + (state) => state.currentTopologyId !== '-1' && state.objects.topology[state.currentTopologyId] + ) + const interactionLevel = useSelector((state) => state.interactionLevel) - return { - topology: state.objects.topology[state.currentTopologyId], - interactionLevel: state.interactionLevel, - } + return } -const TopologyContainer = connect(mapStateToProps)(TopologyGroup) - export default TopologyContainer -- cgit v1.2.3
