As you already know that Deno is a new run time of JavaScript and TypeScript. Recently it has published first stable release.
MongoDB is the most popular NoSQL database. Deno also has a third-party module deno_mongo to handle MongoDB queries.
deno_mongo is a MongoDB database driver for Deno, based on rust's official MongoDB library package. Right now it's on --unstable
flug.
I'm assuming that you have installed MongoDB and Deno on your machine. So, let's see how it works...
Necessary permissions to run this module: --allow-net --allow-write --allow-read --allow-plugin --unstable
import { MongoClient } from "https://deno.land/x/mongo/mod.ts"
const client = new MongoClient()
client.connectWithUri("mongodb://localhost:27017")
const db = client.database("denoDB");
const greetings = db.collection("greetings");
on client.connectWithUri
you will put your own URL. In my case, I have a database called denoDB and a collection called greetings in that database.
Now let's insert some data in there:
const hello = await greetings.insertOne({
sayHello: "Hello World..."
});
If you check on the terminal db.greetings.find()
then you'll get that data back, or you can find the data using deno_mongo:
const find = await greetings.find({
_id: hello
});
console.log(find)
Update and Delete:
updateOne returns { matchedCount, modifiedCount, upsertedId }
these three informations.
// update
const { matchedCount, modifiedCount, upsertedId } = await greetings.updateOne(
{ sayHello: { $ne: null } },
{ $set: { sayHello: "Hello Universe..." } }
);
// delete
const delete = await greetings.deleteOne({ _id: hello });
