## Overview
[MongoDB](https://docs.mongodb.com/v4.2/) is a general purpose, document-based, distributed database built for modern application developers and for the cloud era. MongoDB offers both a Community and an Enterprise version of the database.
The `ballerinax/mongodb` package offers APIs to connect to MongoDB servers and to perform various operations including CRUD operations, indexing, and aggregation.
The Ballerina MongoDB connector is compatible with MongoDB 3.6 and later versions.
## Setup guide
To use the MongoDB connector, you need to have a MongoDB server running and accessible. For that, you can either install MongoDB locally or use the [MongoDB Atlas](https://www.mongodb.com/cloud/atlas/register), the cloud offering of the MongoDB.
### Setup a MongoDB server locally
1. Download and install the MongoDB server from the [MongoDB download center](https://www.mongodb.com/try/download/community).
2. Follow the installation instructions provided in the download center.
3. Follow the [instructions](https://www.mongodb.com/docs/manual/administration/install-community/#std-label-install-mdb-community-edition) for each operating system to start the MongoDB server.
> **Note:** This guide uses the MongoDB community edition for the setup. Alternatively, the enterprise edition can also be used.
### Setup a MongoDB server using MongoDB Atlas
1. Sign up for a free account in [MongoDB Atlas](https://www.mongodb.com/cloud/atlas/register).
2. Follow the instructions provided in the [MongoDB Atlas documentation](https://docs.atlas.mongodb.com/getting-started/) to create a new cluster.
3. Navigate to your MongoDB Atlas cluster.
4. Select "Database" from the left navigation pane under the "Deployment" section and click "connect" button to open connection instructions.
5. Add your IP address to the IP access list or select "Allow access from anywhere" to allow all IP addresses to access the cluster.
6. Click "Choose a connection method" and select "Drivers" under the "Connect your application". There you can find the connection string to connect to the MongoDB Atlas cluster.
## Quickstart
### Step 1: Import the module
Import the `mongodb` module into the Ballerina project.
```ballerina
import ballerinax/mongodb;
```
### Step 2: Initialize the MongoDB client
#### Initialize the MongoDB client using the connection parameters
```ballerina
mongodb:Client mongoDb = check new ({
connection: {
serverAddress: {
host: "localhost",
port: 27017
},
auth: {
username: ,
password: ,
database:
}
}
});
```
#### Initialize the MongoDB client using the connection string
```ballerina
mongodb:Client mongoDb = check new ({
connection:
});
```
### Step 3: Invoke the connector operation
Now, you can use the available connector operations to interact with MongoDB server.
#### Retrieve a Database
```ballerina
mongodb:Database moviesDb = check mongoDb->getDatabase("movies");
```
#### Retrieve a Collection
```ballerina
mongodb:Collection moviesCollection = check moviesDb->getCollection("movies");
```
#### Insert a Document
```ballerina
Movie movie = {title: "Inception", year: 2010};
check moviesCollection->insert(movie);
```
### Step 4: Run the Ballerina application
Save the changes and run the Ballerina application using the following command.
```bash
bal run
```
## Examples
The MongoDB connector provides practical examples illustrating usage in various scenarios. Explore these [examples](https://github.com/ballerina-platform/module-ballerinax-mongodb/tree/master/examples/) covering common MongoDB operations.

## Building from the source
### Setting up the prerequisites
1. Download and install Java SE Development Kit (JDK) version 17. You can download it from either of the following sources:
* [Oracle JDK](https://www.oracle.com/java/technologies/downloads/)
* [OpenJDK](https://adoptium.net/)
> **Note:** After installation, remember to set the `JAVA_HOME` environment variable to the directory where JDK was installed.
2. Download and install [Ballerina Swan Lake](https://ballerina.io/).
3. Download and install [Docker](https://www.docker.com/get-started).
> **Note**: Ensure that the Docker daemon is running before executing any tests.
4. Export Github Personal access token with read package permissions as follows,
```bash
export packageUser=
export packagePAT=
```
### Building the source
Execute the commands below to build from the source.
1. To build the package:
```bash
./gradlew clean build
```
2. To run the tests:
```bash
./gradlew clean test
```
3. To build the without the tests:
```bash
./gradlew clean build -x test
```
4. To run selected test groups:
```bash
./gradlew clean test -P groups=
```
5. To debug package with a remote debugger:
```bash
./gradlew clean build -P debug=
```
6. To debug with the Ballerina language:
```bash
./gradlew clean build -P balJavaDebug=
```
7. Publish the generated artifacts to the local Ballerina Central repository:
```bash
./gradlew clean build -P publishToLocalCentral=true
```
