Documentatie Express&Mongo

Basis Express Application

index.ts

import express from "express"; // importeer de express module
import {apiRouter} from "./routes/api";

const app = express(); // maak een express applicatie aan

app.set("port", 3000); // definieer de poort
app.set('view engine', 'ejs');
app.set('views', `/views`);

app.use(express.static(`/public`));

app.listen(app.get("port"), () => // gebruik de poort en toon een boodschap als dit lukt
  console.log(`[server] http://localhost: ${app.get("port")}`)
);

app.use(`/api`, apiRouter);

MongoDB Connection

Vergeet de volgende zaken niet aan te passen!

• username (MY_USERNAME)

• password (MY_PASSWORD)

• uri (MY_MONGODB_URL)

routes/api.ts

import express from "express";
import * as MongoClientModule from "mongodb";

const username = "MY_USERNAME";
const password = "MY_PASSWORD";

const uri = `mongodb+srv://${username}:${password}@MY_MONGODB_URL`;
const client = new MongoClientModule.MongoClient(uri);

const router = express.Router();
router.get("/data", async (req : any, res : any) => { 
    client
        .db("WebOntwikkeling")
        .collection("MY_COLLECTION")
        .find({})
        .toArray()
        .then(data => {
            res
                .status(200)
                .json(data);
        });
});

export {router as apiRouter}
