This is my main file index.js

type here const express = require("express"); const app = express(); require("dotenv").config(); const port = process.env.port || 4000; app.use(express.json()); const createBlog = require("./routes/blogRoutes"); app.use("/santi/api/v1",createBlog); app.listen(port, () => { console.log("App run in 3000 port"); }) const dbConnect = require("./config/database"); dbConnect(); app.get("/", (req,res) => { res.send(`
this is homepage
`); })

This is my route

const express = require("express"); const router = express.Router(); const {createBlog} = require("../controlers/createBlog"); router.post("/createBlog",createBlog); module.exports = router;

This is my controller file

const createPost = require("../models/post"); exports.post = async (req,res) => { try { const {title,description} = req.body; const response = await createPost.create({title,description}); res.status(200).json({ status:true, message:"Insert seccessfully", data:response }) } catch(error) { console.error(err); res.status(500).json({ status:false, message:error.message, data:"Server issue" }) } }

This is my model file

const mongoose = require("mongoose"); const blogPostSchema = new mongoose.Schema( { title:{ type:String, required:true, maxlength:50 }, description:{ type:String, required:true, maxlength:50 } } ) module.exports = mongoose.model("blogPost",blogPostSchema);

I installed nodemon and mongoose but still getting error in terminal after writing "npm run dev" command

What is the solution?

const createPost = require("../models/post"); exports.createBlog = async (req,res) => { try { const {title,description} = req.body; const response = await createPost.create({title,description}); res.status(200).json({ status:true, message:"Insert seccessfully", data:response }) } catch(error) { console.error(err); res.status(500).json({ status:false, message:error.message, data:"Server issue" }) } }

const express = require("express"); const router = express.Router(); const {post} = require("../controlers/createBlog"); router.post("/createBlog",post); module.exports = router;
