1-3: Consider adding a type annotation to the global variable.The global variable
mongoClientis correctly used for connection reuse. However, it's initially undefined and should be typed as such.Consider updating the declaration as follows:
-let mongoClient: mongoDB.MongoClient; +let mongoClient: mongoDB.MongoClient | undefined;This change will make the type more accurate and prevent potential TypeScript errors.

4-4: LGTM: New MongoDB import added.The new import for
getMongoDBis correctly placed and aligns with the transition to direct MongoDB interaction.
6-6: LGTM: Handler function made asynchronous.The handler function has been correctly updated to be asynchronous, which is necessary for the new MongoDB operations.
21-24: LGTM: Response handling updated correctly.The response structure has been appropriately updated to include the inserted document ID from MongoDB. The use of status code 200 for a successful operation is correct.
17-20: LGTM: MongoDB interaction implemented correctly.The new code correctly uses the
getMongoDB()function and inserts the donation data into the database. However, please verify if 'failed_donation' is the intended collection name for this operation.To verify the collection name usage across the codebase, run the following script:
Verification successful
Verified: 'failed_donation' collection name is used correctly.

The following scripts were executed for the analysis:

48-48: Verify MongoDB version and update lockfileThe addition of the MongoDB dependency aligns with the PR objectives. However, consider the following points:
- The specific version (6.9.0) is pinned. Verify if this is the intended version or if using a more flexible version range (e.g., "^6.9.0") would be beneficial for future updates.
- Ensure that the corresponding lockfile (package-lock.json or yarn.lock) is updated and included in this PR to maintain consistency across environments.
- Consider the impact of this new dependency on the project's build time and runtime performance.
To verify the MongoDB version and check for any potential issues, run the following script:

Consider adding a connection closing function and improving documentation.
The overall structure of the file is good, but there are a couple of improvements that could be made:
-
There's no mechanism to close the MongoDB connection when it's no longer needed.
-
The file lacks comments and documentation.
-
Consider adding a function to close the MongoDB connection:
export async function closeMongoDB(): Promise<void> {
if (mongoClient) {
await mongoClient.close();
mongoClient = undefined;
}
}- Add JSDoc comments to explain the purpose of each function and any important details:
/**
* Connects to MongoDB using the connection URI from environment variables.
* Reuses an existing connection if available.
* @throws {Error} If the connection URI is not set or if the connection fails.
* @returns {Promise<mongoDB.MongoClient>} The connected MongoDB client.
*/
export async function connectToMongo() {
// ... existing code ...
}
/**
* Retrieves a MongoDB database instance.
* Ensures a connection is established before returning the database.
* @throws {Error} If the database name is not set in environment variables.
* @returns {Promise<mongoDB.Db>} The MongoDB database instance.
*/
export async function getMongoDB(): Promise<mongoDB.Db> {
// ... existing code ...
}These changes will improve the overall robustness and maintainability of the code.

Add a check for the database name environment variable.
The getMongoDB function correctly ensures a connection before getting a database instance. However, it doesn't verify if the MONGO_DONATION_DATABASE environment variable is set.
Consider adding a check for the database name:
export async function getMongoDB(): Promise<mongoDB.Db> {
const client = await connectToMongo();
- return client.db(process.env.MONGO_DONATION_DATABASE);
+ const dbName = process.env.MONGO_DONATION_DATABASE;
+ if (!dbName) {
+ throw new Error('MONGO_DONATION_DATABASE is not set');
+ }
+ return client.db(dbName);
}This change will ensure that the function fails early if the required environment variable is not set, preventing potential issues later in the application.

Fix typo and improve error handling in connectToMongo function.
There are a few issues in the connectToMongo function that need attention:
- There's a typo in the environment variable name.
- The error message is inconsistent with the actual variable name used.
- The function doesn't handle potential connection errors.
Please apply the following changes:
-const url = process.env.MONGO_DOATION_CONNECTION_URI;
+const url = process.env.MONGO_DONATION_CONNECTION_URI;
if (!url) {
- throw new Error('MONGODB_CONNECTION_URL is not set');
+ throw new Error('MONGO_DONATION_CONNECTION_URI is not set');
}
if (!mongoClient) {
mongoClient = new mongoDB.MongoClient(url);
- await mongoClient.connect();
+ try {
+ await mongoClient.connect();
+ } catch (error) {
+ console.error('Failed to connect to MongoDB:', error);
+ throw error;
+ }
}These changes will correct the typo, make the error message consistent, and add proper error handling for the connection process.

@lovelgeorge99 You have typo error here process.env.MONGO_DOATION_CONNECTION_URI
It should not be process.env.MONGO_DONATION_CONNECTION_URI ?

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!

Improved error handling, but consider enhancing client error response.
The error handling has been significantly improved with detailed logging and Sentry error capturing. This is great for debugging and monitoring. However, the error response to the client is minimal.
Consider providing more informative error responses to the client. For example:
- res.status(500).json();
+ res.status(500).json({ message: 'An error occurred while processing your request. Please try again later.' });This gives the client more context without exposing sensitive information.
