27-27: Consider initializing the client toundefined
Although it's declared now, it might be good for clarity to set it toundefinedexplicitly to make it clear that it’s not yet connected.- let client: MongoClient + let client: MongoClient | undefined
59-60: Log errors on repeated connection attempts
Currently, errors duringclient.connect()are ignored with an empty catch. Consider logging them in case insight is needed into repeated connection failures.try { await client.connect() - } catch {} + } catch (err) { + logger.warn('Failed to connect to MongoDB in deletableFunction:', err) + }
98-100: Log errors on repeated connection attempts
Same recommendation as for the deletableFunction. Logging might help diagnose repeated connection issues in addDocumentsFunction.try { await client.connect() - } catch {} + } catch (err) { + logger.warn('Failed to connect to MongoDB in addDocumentsFunction:', err) + }
116-119: Remove or implement the commented-out save logic
Leaving commented-out code can lead to confusion. If the logic is no longer needed, remove it to improve readability; otherwise, finalize and test it.

6-6: Great use of type-only import for MongoClient
This helps to ensure type safety without bundling the entire module.
29-31: Connection logic is clear and properly enclosed in a try-catch
This refactoring ensures that we handle errors gracefully when connecting to MongoDB.
33-39: Properly closing the client on disposal
Good check to ensure the connection is only closed if it exists. This prevents crashes on shutdown.

Good implementation of connection cleanup with null check and logging.
Line range hint 37-55: LGTM! Proper vector store initialization
The vector store setup is well-structured with all necessary configuration parameters.

🛠️ Refactor suggestion
Add error handling for MongoDB connection
The connection attempt should include error handling to gracefully handle connection failures and provide meaningful error messages.
- client = new MongoDB.MongoClient(config.mongodbUrl)
- await client.connect()
+ client = new MongoDB.MongoClient(config.mongodbUrl)
+ try {
+ await client.connect()
+ logger.info('Successfully connected to MongoDB')
+ } catch (error) {
+ logger.error(`Failed to connect to MongoDB: ${error.message}`)
+ throw error
+ }📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
| client = new MongoDB.MongoClient(config.mongodbUrl) | |
| await client.connect() | |
| client = new MongoDB.MongoClient(config.mongodbUrl) | |
| try { | |
| await client.connect() | |
| logger.info('Successfully connected to MongoDB') | |
| } catch (error) { | |
| logger.error(`Failed to connect to MongoDB: ${error.message}`) | |
| throw error | |
| } |

26-35: Consider implementing a connection managerThe current implementation handles connections independently in each operation. Consider implementing a centralized connection manager to handle connection lifecycle and state.
This could include:
- Connection state tracking
- Automatic reconnection with backoff
- Connection pooling
- Centralized error handling
Would you like me to provide an example implementation of a MongoDB connection manager class?

85-87:
Add error handling for ObjectId conversion
Converting string IDs to ObjectId can fail if the input format is invalid. Add proper error handling.
_id: {
- $in: ids.map((id) => new MongoDB.ObjectId(id))
+ $in: ids.map((id) => {
+ try {
+ return new MongoDB.ObjectId(id)
+ } catch (error) {
+ logger.warn(`Invalid ObjectId format: ${id}, skipping...`)
+ return null
+ }
+ }).filter(Boolean)
}Likely invalid or redundant comment.
28-29:
Add robust connection error handling
The MongoDB connection attempt should include proper error handling and logging.
- await client.connect()
+ try {
+ await client.connect()
+ logger.info('Successfully connected to MongoDB vector store')
+ } catch (error) {
+ logger.error(`Failed to connect to MongoDB vector store: ${error.message}`)
+ throw new Error(`MongoDB connection failed: ${error.message}`)
+ }Likely invalid or redundant comment.

Improve connection management in add documents function
Similar to the delete function, improve connection handling and error management.
try {
- await client.connect()
+ if (!client.isConnected()) {
+ await client.connect()
+ logger.debug('Reconnected to MongoDB for add operation')
+ }
} catch (error) {
