How do I JSONEncode CFrame and Vector3 values?

So, I'm testing data storing parts through a table library, and since you can't datastore libraries, im going to have to use JSONEncode and Decode right? Well the library has vector3 values in it and it isn't Encoding them. How would I make it so that JSONEncode includes these values? Thanks!

local DataStore = game:GetService('DataStoreService'):GetDataStore('BaseStore')

Bases = {}
if not DataStore:GetAsync('BaseStore1') then
	print ("Yes")
	local AddPart = function()
		Bases['Part'] = {}
		Bases.Part['Anchored'] = true
		Bases.Part['Size'] = Vector3.new(5, 5, 5)
		Bases.Part['Position'] = CFrame.new (0, 20, 0)
	end
	
	AddPart()
else 
	Bases = game:GetService('HttpService'):JSONDecode(DataStore:GetAsync('BaseStore1'))
	print (game:GetService('HttpService'):JSONDecode(DataStore:GetAsync('BaseStore1')))
	for i, v in pairs (Bases.Part) do
		print (i)
	end
end

local Part = Instance.new ('Part')
Part.Anchored = Bases.Part.Anchored
Part.Size = Bases.Part.Size
Part.CFrame = Bases.Part.Position
Part.Parent = workspace

print (game:GetService'HttpService':JSONEncode(Bases))
DataStore:SetAsync('BaseStore1', game:GetService'HttpService':JSONEncode(Bases))

I haven't really tested these functions, but try them out:

local HttpService = game:GetService("HttpService")
local function EncodeVector3(Vector3)
	--- Encodes a Vector3 in JSON
	-- @param Vector3 The Vector3 to encode
	-- @return String The string representation in JSON of the Vector3 value.

	return HttpService:JSONEncode{
		Vector3.x;
		Vector3.y;
		Vector3.z;
	}
end

local function DecodeVector3(Data)
	--- decode's a previously encoded Vector3.
	-- @param Data String of JSON, that was encoded.
	-- @return Vector3 if it could be decoded, otherwise, nil
	
	if Data then
		local DecodedData = HttpService:JSONDecode(Data)
		if DecodedData then
			return Vector3.new(unpack(DecodedData))
		end
	end
	return nil
end

local function EncodeCFrame(CFrameValue)
	--- Encodes a CFrameValue in JSON

	return HttpService:JSONEncode{CFrameValue:components()}
end

local function DecodeCFrame(Data)
	--- decode's a previously encoded CFrameValue.
	
	if Data then
		local DecodedData = HttpService:JSONDecode(Data)
		if DecodedData then
			return CFrame.new(unpack(DecodedData))
		end
	end
	return nil
end
