How to check the data size of a value?

ForeverHD · October 31, 2019, 6:30pm

When using MessagingService:PublishAsync(topic, value) we are limited to ~1kb of data per request. How can we check the data size of these values?

e.g.

getSize(("a"):rep(64))

64 characters

The values may be tables of unpredictable data sizes.

Perhaps you could loop through the table and have a reference table of how many bytes that datatype takes up?

local reference = {
    ["string"] = 1,
    ["number"] = 2, --It's 2 bytes right?
}
local amount = 0

if typeof(data) == "table" then
    for _, v in pairs(data) do
        amount = amount + reference[typeof(v)]
    end
else
    amount = reference[typeof(data)]
end

local HttpService = game:GetService("HttpService")

local data = 'okaaaaaaaaaaaahhhhhy'
print(#HttpService:JSONEncode(data))
-- > 22

local data2 = {'cat','dog','bird','tiger'}
print(#HttpService:JSONEncode(data2))
-- > 28
