OUTDATED AND OLD, DO NOT USE!
I’ll be explaining how to get and set data using an express server that uses replit databases.
don’t flame my nodejs code i’m new to js
Why should I do this?
- Perhaps you want to modify and get data using discord bots
- Or you just want more control over your data
In order to do this you need:
- Replit Account
- Basic knowledge of roblox scripting
Note that roblox ONLY allows up to 500 HTTP Requests per minute.
Repl:
First of all start by making a new repl
Then select Node.js
Once you done that simply press on Create Repl
Then a page should open with a file called index.js, simply paste this.
const Database = require("@replit/database")
const db = new Database()
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser.json());
app.get('/', (req, res) => {
res.send('hello')
});
app.post('/getData', (req, res) => {
if (req.headers && req.headers["authorization"] && req.headers["authorization"] === process.env.authorization) {
if (req.body["key"]) {
db.get(req.body["key"]).then(data => {
if (data === null) {
res.send({success: true, data: "{}"})
} else {
res.send({success: true, data: data})
}
})
} else {
res.send({success: false, data: "Body did not contain a key"})
}
} else {
res.send({success: false, data: "Forbidden 403"})
}
})
app.post('/setData', (req, res) => {
if (req.headers && req.headers["authorization"] && req.headers["authorization"] === process.env.authorization) {
if (req.body["key"] && req.body["data"]) {
db.set(req.body["key"], req.body["data"]).then(() => {})
res.send({success: true})
} else {
res.send({success: false, data: "Body did not contain a key or a data value"})
}
} else {
res.send({success: false, data: "Forbidden 403"})
}
})
app.listen(3000, () => {
console.log('server started');
});
After that, go on the right and find the + and click on it.
And now press on Secrets after you find it
Press on Create Secret
After that just press Add Secret after you put a key that you actually remember.
Hopefully you are keeping track, after that just press “Run”
If there is un-installed packages, wait for replit to install them and wait for a “Webview” tab to open up.
And once you do that copy the URL over here.
Roblox Studio:
Start by opening up a published place that has HTTP Requests enabled (you can find this in the game settings)
Make a script in ServerScriptService and call it whatever you want, after doing that paste this into the code and configure it.
-- written by @aisarredux on discord
local HttpService = game:GetService("HttpService")
local dataServerURL = "put here the URL that you copied"; -- IF THERE IS A / AT THE END, REMOVE IT.
local dataHeaders = {
["authorization"] = "put the SECRET that you made in replit here"
}
function CheckTableEquality(t1,t2)
for i,v in next, t1 do if t2[i]~=v then return false end end
for i,v in next, t2 do if t1[i]~=v then return false end end
return true
end
local startingData = {}
game:GetService("Players").PlayerAdded:Connect(function(player)
local httpConnection = HttpService:PostAsync(dataServerURL.. "/getData", HttpService:JSONEncode({key = "Player_" .. player.UserId}), Enum.HttpContentType.ApplicationJson, nil, dataHeaders)
local request;
local requestSuccess;
if httpConnection then
requestSuccess, request = pcall(HttpService.JSONDecode, HttpService, httpConnection)
end
if requestSuccess then
local parsed, data = pcall(HttpService.JSONDecode, HttpService, request.data)
if parsed then
if request.success and data then
if CheckTableEquality(data, {}) then
-- DATA IS EMPTY
data = {
Coins = 0;
}
-- RECONCILED DATA
end
startingData[player] = data;
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player
for dataName, dataValue in pairs(data) do
local value = "StringValue"
if typeof(dataValue) == "number" then
value = "NumberValue"
elseif typeof(dataValue) == "boolean" then
value = "BoolValue"
end
local dataInstance = Instance.new(value)
dataInstance.Name = dataName
dataInstance.Value = dataValue
dataInstance.Parent = leaderstats
end
else
warn("DataManager: COULD NOT LOAD ".. player.Name .." (" .. player.UserId ..") RETURNING INFO WAS " .. (request.data and request.data or "null") .. ".")
player:Kick("Met with an error while retrieving your data.")
end
else
player:Kick("Could not correctly parse your JSON data.")
end
else
player:Kick("Could not retrieve your data.")
end
end)
game:GetService("Players").PlayerRemoving:Connect(function(player)
local endingData = {}
for _, v in pairs(player:WaitForChild("leaderstats"):GetChildren()) do
endingData[v.Name] = v.Value;
end
if CheckTableEquality(startingData[player], endingData) then
warn("not saving data due to it not changing")
return
end
endingData = HttpService:JSONEncode(endingData)
local httpConnection = HttpService:PostAsync(dataServerURL.. "/setData", HttpService:JSONEncode({key = "Player_" .. player.UserId, data = endingData}), Enum.HttpContentType.ApplicationJson, nil, dataHeaders)
local request;
local requestSuccess;
if httpConnection then
requestSuccess, request = pcall(HttpService.JSONDecode, HttpService, httpConnection)
end
if requestSuccess and not request.success then
warn("DataManager: had an error while saving ".. player.Name .. " (" .. player.UserId ..")'s data message was ".. (request.data and request.data or "null"))
elseif not requestSuccess then
warn("DataManager: had an error while saving ".. player.Name .. " (" .. player.UserId ..")'s data message was " .. (request and request or "null"))
end
end)
And like that, you should have a working replit database system.
If you couldn’t understand or the code errors, reply to this topic with your issue.
Hopefully this helps anyone.
