# @push.rocks/mongodump
a tool to handle dumps of MongoDB databases

## Install
To use @push.rocks/mongodump in your project, run:
```bash
npm install @push.rocks/mongodump --save
```

## Usage

This guide provides an overview of how to work with @push.rocks/mongodump to handle dumps of MongoDB databases efficiently.

### Setting up a MongoDB Dump Target
First, you'll need to describe your MongoDB database using an interface provided by the module. Here's a sample descriptor:

```typescript
import { IMongoDescriptor } from '@tsclass/tsclass';
import { MongoDump, MongoDumpTarget } from '@push.rocks/mongodump';

const myMongoDescriptor: IMongoDescriptor = {
  mongoDbName: '<database_name>',
  mongoDbUser: '<database_user>',
  mongoDbPass: '<database_password>',
  mongoDbUrl: 'mongodb+srv://<user>:<password>@<cluster_url>/<dbname>?retryWrites=true&w=majority',
};
```

### Creating and Using the MongoDump Instance
To interact with MongoDB for dumping purposes, you'll use the `MongoDump` class:

```typescript
async function setupMongoDump() {
  const mongoDump = new MongoDump();
  const mongoDumpTarget = await mongoDump.addMongoTargetByMongoDescriptor(myMongoDescriptor);

  // mongoDumpTarget can now be used for further operations
}
setupMongoDump();
```

### Dumping Collections to a Directory
To dump the collections of a database into a directory with files representing each document, you can use the `dumpCollectionToDir` method. This method is useful for creating backups or migrating data:

```typescript
async function dumpCollections() {
  const mongoDump = new MongoDump();
  const mongoDumpTarget = await mongoDump.addMongoTargetByMongoDescriptor(myMongoDescriptor);

  await mongoDumpTarget.dumpAllCollectionsToDir('./path/to/dumpDir', null, true);
  // This dumps all collections to the specified directory, cleaning the directory before dumping.
}
dumpCollections();
```

### Advanced Dumping Options
For more control over the dumping process, including naming conventions for dumped files or handling specific collections, you can explore methods like `dumpCollectionToDir` for individual collections and advanced configurations concerning directory cleanliness and document naming.

### Shutting Down Properly
It's important to close down database connections properly once your dumping operations are complete:

```typescript
async function shutDownMongoDump() {
  const mongoDump = new MongoDump();
  await mongoDump.stop();
  // Closes all open database connections gracefully
}
shutDownMongoDump();
```

### Conclusion
The @push.rocks/mongodump module provides a flexible approach to handling MongoDB database dumps, whether it's for backup, migration, or other purposes. By leveraging TypeScript and modern async patterns, it integrates smoothly into modern Node.js applications focused on MongoDB interactions.
