# deno_mongo
> **deno_mongo** is a **MongoDB** database driver developed for Deno. supports
> Deno Deploy as well.
## ATTENTION
**Deno have added the support for npm modules. so you can also use `npm:mongodb`
driver from now.**\
Each of these two drivers has its own advantages and disadvantages. you can
follow [this](https://github.com/denodrivers/mongo/issues/380) issue for more
details. In short:
- if you want to use basic MongoDB operations and you don't care about
stability, this driver just works.
- if you want most of MongoDB feature working with Deno and you don't care about
the possible overheads by using node compat layer, you may try the
`npm:mongodb` driver
- if you are using MongoDB Atlas, using
[atlas_sdk](https://github.com/erfanium/atlas_sdk) can be your best option.

### Import
Replace `LATEST_VERSION` with
[current latest version](https://deno.land/x/mongo)
```ts
import {
Bson,
MongoClient,
} from "https://deno.land/x/mongo@LATEST_VERSION/mod.ts";
```
### Connect
```ts
const client = new MongoClient();
// Connecting to a Local Database
await client.connect("mongodb://127.0.0.1:27017");
// Connecting to a Mongo Atlas Database
await client.connect({
db: "",
tls: true,
servers: [
{
host: "",
port: 27017,
},
],
credential: {
username: "",
password: "",
db: "",
mechanism: "SCRAM-SHA-1",
},
});
// Connect using srv url
await client.connect(
"mongodb+srv://:@/?authMechanism=SCRAM-SHA-1",
);
```
### Access Collection
```ts
// Defining schema interface
interface UserSchema {
_id: ObjectId;
username: string;
password: string;
}
const db = client.database("test");
const users = db.collection("users");
```
### Insert
```ts
const insertId = await users.insertOne({
username: "user1",
password: "pass1",
});
const insertIds = await users.insertMany([
{
username: "user1",
password: "pass1",
},
{
username: "user2",
password: "pass2",
},
]);
```
### Find
```ts
const user1 = await users.findOne({ _id: insertId });
const all_users = await users.find({ username: { $ne: null } }).toArray();
// find by ObjectId
const user1_id = await users.findOne({
_id: new ObjectId("SOME OBJECTID STRING"),
});
```
### Count
```ts
const count = await users.countDocuments({ username: { $ne: null } });
const estimatedCount = await users.estimatedDocumentCount({
username: { $ne: null },
});
```
### Aggregation
```ts
const docs = await users.aggregate([
{ $match: { username: "many" } },
{ $group: { _id: "$username", total: { $sum: 1 } } },
]).toArray();
```
### Update
```ts
const { matchedCount, modifiedCount, upsertedId } = await users.updateOne(
{ username: { $ne: null } },
{ $set: { username: "USERNAME" } },
);
const { matchedCount, modifiedCount, upsertedId } = await users.updateMany(
{ username: { $ne: null } },
{ $set: { username: "USERNAME" } },
);
```
### Replace
```ts
const { matchedCount, modifiedCount, upsertedId } = await users.replaceOne(
{ username: "a" },
{
username: "user1",
password: "pass1",
}, // new document
);
```
### Delete
```ts
const deleteCount = await users.deleteOne({ _id: insertId });
const deleteCount2 = await users.deleteMany({ username: "test" });
```
### Cursor methods
```ts
const cursor = users.find();
// Skip & Limit
cursor.skip(10).limit(10);
// iterate results
for await (const user of cursor) {
console.log(user);
}
// or save results to array (uses more memory)
const users = await cursor.toArray();
```
### GridFS
```ts
// Upload
const bucket = new GridFSBucket(db);
const upstream = bucket.openUploadStream("test.txt");
const writer = upstream.getWriter();
writer.write(fileContents);
await writer.close();
// Download
const file = await new Response(bucket.openDownloadStream(id)).text();
```
