About the Config editing section

An adventure with React, React Hooks and Ant Design forms.

General data flow in this React app

When the Admin app loads, the ServerStatusContext (in addition to checking server /status on a timer) makes a call to the /serverconfig API to get your config details. This data will be stored as serverConfig in app state, and provided to the app via useContext hook.
The serverConfig in state is be the central source of data that pre-populates the forms.
The ServerStatusContext also provides a method for components to update the serverConfig state, called setFieldInConfigState().
After you have updated a config value in a form field, and successfully submitted it through its endpoint, you should call setFieldInConfigState to update the global state with the new value.
Each top field of the serverConfig has its own API update endpoint.

Each form input (or group of inputs) you make, you should

Get the field values that you want out of serverConfig from ServerStatusContext with useContext.
Next we'll have to put these field values of interest into a useState in each grouping. This will help you edit the form.
Because ths config data is populated asynchronously, Use a useEffect to check when that data has arrived before putting it into state.
You will be using the state's value to populate the defaultValue and the value props of each Ant input component (Input, Toggle, Switch, Select, Slider are currently used).
When an onChange event fires for each type of input component, you will update the local state of each page with the changed value.
Depending on the form, an onChange of the input component, or a subsequent onClick of a submit button will take the value from local state and POST the field's API.
onSuccess of the post, you should update the global app state with the new value.

There are also a variety of other local states to manage the display of error/success messaging.

The text field is intentionally designed to make it difficult for the user to submit bad data.
If you make a change on a field, a Submit buttton will show up that you have to click to update. That will be the only way you can update it.
If you clear out a field that is marked as Required, then exit/blur the field, it will repopulate with its original value.
Both of these elements are specifically meant to be used with updating serverConfig fields, since each field requires its own endpoint.
Give these fields a bunch of props, and they will display labelling, some helpful UI around tips, validation messaging, as well as submit the update for you.
(currently undergoing re-styling and TS cleanup)
NOTE: you don't have to use these components. Some form groups may require a customized UX flow where you're better off using the Ant components straight up.
