import express from "express"
import { MongoClient, ServerApiVersion } from "mongodb"
import { ObjectId } from "mongodb"
import cors from "cors"
import "dotenv/config"
const app = express()
app.use(cors())
app.use(express.json())
const PORT = process.env.PORT || 5000
const uri = `mongodb+srv://${process.env.DB_USER}:${process.env.DB_PASSWORD}#laptopstock.xnbrc.mongodb.net/myFirstDatabase?retryWrites=true&w=majority&ssl=true`
const client = new MongoClient(uri, {
useNewUrlParser: true,
useUnifiedTopology: true,
serverApi: ServerApiVersion.v1,
})
async function run() {
try {
await client.connect()
const laptopCollection = client.db("laptop_stock").collection("laptops")
app.post("/product", async (req, res) => {
const products = req.body
// console.log(products)
const NewProducts = await laptopCollection.insertOne(products)
res.send(products)
})
// get products
app.get("/product", async (req, res) => {
const query = {}
const cursor = laptopCollection.find(query)
const loadData = await cursor.toArray()
// console.log(loadData)
res.send(loadData)
})
app.get("/product/:id", async (req, res) => {
const id = req.params.id
const query = { _id: ObjectId(id) }
const service = await laptopCollection.findOne(query)
res.send(service)
})
app.put("/update/:id", async (req, res) => {
const id = req.params.id
const data = req.body
const filter = { _id: ObjectId(id) }

}
const updateProduct = await laptopCollection.updateOne(
filter,
updateDoc,
options,

res.send(updateProduct)
})
app.delete("/product/:id", async (req, res) => {
const id = req.params.id
const query = { _id: ObjectId(id) }
const deleteLaptop = await laptopCollection.deleteOne(query)
res.send(deleteLaptop)
})
} catch (error) {
console.log({ massage: error })
}
}
app.get("/", (req, res) => {
res.send({ message: "success" })
})
run()
app.listen(PORT, () => {
console.log("server is running port", PORT)
