A modern CLI tool to import/export MongoDB collections to and from JSON or CSV — great for backups, migrations, and local development.

import { MongoClient } from 'mongodb';
import { logger } from '../utils/logger.js';
import { config } from '../config.js';
export class MongoDBClient {
    constructor(uri) {
        this.client = new MongoClient(uri || config.mongo.uri);
    }
    async connect() {
        await this.client.connect();
        logger.info('Connected to MongoDB');
        const db = this.client.db(config.mongo.dbName);
        return db;
    }
    async listDatabases() {
        try {
            const adminDb = this.client.db('admin').admin();
            const dbs = await adminDb.listDatabases();
            return dbs.databases
                .map((db) => db.name)
                .filter(name => !['admin', 'local', 'config'].includes(name));
        }
        catch (error) {
            logger.error(`Failed to list databases: ${error.message}`);
            return [];
        }
    }
    async close() {
        await this.client.close();
        logger.info('MongoDB connection closed');
    }
}
