hi every body i have question on connecting nextJs to mongodb on startup of server. as u know nextjs is fs framework and im migrationg from node/express to it but my problem is how to connect server to database at startup of server as i did in express? there is now where to put my initalizing code in nextjs?am i saying correct? i saw some code to to that but there were typescript codes that im not familiar with them
on the other hand i'm able to do that on serverside functions like getStaticProps or getServerSideProps this is my code
dbinit.js
import mongoose from "mongoose";
export const dbStatus = () => mongoose.connection.readyState;
export default function dbConnect() {
if (dbStatus == 1) return "database is connected";
mongoose.connect(
`mongodb://localhost:${process.env.DBPORT}/${process.env.DBNAME}`
);
}
index.js
export async function getServerSideProps() {
const result = await dbConnect();
console.log(dbStatus());
return {
props: {},
};
}
with this code im able to connect to mongodb but there are some problems and the most important is that mycode isnot cleancode
In NextJS, we can connect MongoDB as middleware. This is very similar to the Express middleware approach as shown below.
// middleware/database.js
import { MongoClient } from 'mongodb';
import nextConnect from 'next-connect';
const client = new MongoClient('{YOUR-MONGODB-CONNECTION-STRING}', {
useNewUrlParser: true,
useUnifiedTopology: true,
});
async function database(req, res, next) {
if (!client.isConnected()) await client.connect();
req.dbClient = client;
req.db = client.db('MCT');
return next();
}
const middleware = nextConnect();
middleware.use(database);
export default middleware;
