May want to add a comment here as to why this is being disabled -- when I added displayName's for the below three components (AppPluginRoot, StartApp, and SiemApp) they were not being shown in the react dev tools Component tree, so I assume this is the reason?

+  pageFilters?: esFilters.Filter[];
+}
+
+const AlertsTableComponent: React.FC<Props> = ({ endDate, startDate, pageFilters = [] }) => {


What is the intent of creating this intermediary AlertsTableComponent using React.FC and then wrapping as AlertsTable using React.memo vs the previous implementation of just using React.memo?

React.memo propagates name of the wrapped component, but as we were passing an inline function to the memo we end up with Anonymus (Memo)

Ahhh, perfect, that's what I was wondering! 🙂

For anyone passing through, @patrykkopycinski outlines this behavior in https://github.com/elastic/siem-team/issues/485.

+/* eslint-disable react/display-name */

Just noting the consistency of naming our connected components. Seems it's hit or miss on if we set the displayName after calling connect(). Here in AuthenticationTable we do not set displayName after connecting, but we do for UncommonProcessTable. The linter rule does not enforce it for connected components, so we'll need to keep an eye out in reviews (or perhaps see if the updated react-redux can handle setting the displayName?).

with react-redux@7 we will be able to migrate from connect to hooks, so the linter will be able to properly enforce the rule 💪

...plugins/siem/public/pages/detection_engine/components/signals/signals_filter_group/index.tsx

+  onFilterGroupChanged: (filterGroup: SignalFilterOption) => void;
+}
+
+const SignalsTableFilterGroupComponent: React.FC<Props> = ({ onFilterGroupChanged }) => {


As above, why the change to React.FC and then wrapping in React.memo below?

Also, in this instance, there is no displayName set for either SignalsTableFilterGroupComponent or SignalsTableFilterGroup and I'm seeing no linter error. If I move SignalsTableFilterGroupComponent back to React.memo I then see the "Component definition is missing displayName" linter error. Any idea why we're not seeing errors here?

for components defined with const the variable name is propagated automatically as a component name, so we don't have to do it manually

-    sendSignalsToTimeline,
-  }) => {
-    const [defaultNumberFormat] = useUiSetting$<string>(DEFAULT_NUMBER_FORMAT);
+const SignalsUtilityBarComponent: React.FC<SignalsUtilityBarProps> = ({


Same clarification as above -- why React.FC then wrapped with React.memo? Also, both SignalsUtilityBarComponent and SignalsUtilityBar are missing displayName and no linter error is shown.

+
+export const StepPanel = memo(StepPanelComponent);
+
+StepPanel.displayName = 'StepPanel';


Seems react-dev-tools will detect the memo and use the displayName of the component being wrapped (adding a Memo tag), so we don't need to add a display name for subsequent memo's (unlike the behavior when wrapping components with connect()).

x-pack/legacy/plugins/siem/public/pages/detection_engine/components/signals_chart/index.tsx

+
+SignalsChartsComponent.displayName = 'SignalsChartsComponent';
+
+export const SignalsCharts = memo(SignalsChartsComponent);


Same question here for why we're abstracting the memo to a parent component? (This component has no props either fwiw)

spong

Tested locally and performed code review. These changes look good to me, but I left a few comments around our methods of adding displayName to connected and memoized components. Approving now, but we may want to standardize on these methods/add additional comments so any inconsistencies don't propagate through the codebase.

@spong Thank you for your comments, I did another round and now I believe it was fixed properly. Would you mind to take a look again?
