//1. Create a custom API for Users data and add different endpoints in express server to perform CRUD  operations on the API.  Test the endpoints using POSTMAN. 
//2. Use EJS view-engine to display the dynamic response. Display the data read from REST API in the form of a table in EJS. 




const express=require("express");
const app=express();

app.use(express.json());
app.set("view engine","ejs");

let users=[
    
    {id:1,name:"Abhi",email:"abhi@gmail.com"},
       { id:2,name:"Vars",email:"Vars@gmail.com"}

    
]


app.get("/users",(req,res)=>{
    res.render('users',{users});
})

app.get("/users/:id",(req,res)=>{
    const user=users.find(u=>u.id===parseInt(req.params.id));
    if(!user) return res.json({message:"No user"});
    res.json(user);
})

app.post("/users",(req,res)=>{
    const {name,email}=req.body;
    const newUser={
        id:users.length+1,
        name:name,
        email:email
    };
    users.push(newUser);
    res.render('users',{users});
});

app.put("/users/:id",(req,res)=>{
    const user=users.find(u=>u.id===parseInt(req.params.id));
    if(!user) return res.json({message:"No user"});
    user.name=req.body.name;
    user.email=req.body.email;
    res.json(user);
