-# Serverless Framework AWS NodeJS Example
+# Serverless Framework Node Express API on AWS
 
-This template demonstrates how to deploy a simple NodeJS function running on AWS Lambda using the Serverless Framework. The deployed function does not include any event definitions or any kind of persistence (database). For more advanced configurations check out the [examples repo](https://github.com/serverless/examples/) which include use cases like API endpoints, workers triggered by SQS, persistence with DynamoDB, and scheduled tasks. For details about configuration of specific events, please refer to our [documentation](https://www.serverless.com/framework/docs/providers/aws/events/).
+This template demonstrates how to develop and deploy a simple Node Express API service running on AWS Lambda using the Serverless Framework.
+
+This template configures a single function, `api`, which is responsible for handling all incoming requests using the `httpApi` event. To learn more about `httpApi` event configuration options, please refer to [httpApi event docs](https://www.serverless.com/framework/docs/providers/aws/events/http-api/). As the event is configured in a way to accept all incoming requests, the Express.js framework is responsible for routing and handling requests internally. This implementation uses the `serverless-http` package to transform the incoming event request payloads to payloads compatible with Express.js. To learn more about `serverless-http`, please refer to the [serverless-http README](https://github.com/dougmoscrop/serverless-http).
 
 ## Usage
 
 ### Deployment
 
-In order to deploy the example, you need to run the following command:
+Install dependencies with:
+
+```
+npm install
+```
+
+and then deploy with:
 
-```bash
+```
 serverless deploy
 ```
 
 After running deploy, you should see output similar to:
 
-```bash
-Deploying "aws-node" to stage "dev" (us-east-1)
+```
+Deploying "aws-node-express-api" to stage "dev" (us-east-1)
 
-✔ Service deployed to stack aws-node-dev (90s)
+✔ Service deployed to stack aws-node-express-api-dev (96s)
 
+endpoint: ANY - https://xxxxxxxxxx.execute-api.us-east-1.amazonaws.com
 functions:
-  hello: aws-node-dev-hello (1.5 kB)
+  api: aws-node-express-api-dev-api (2.3 kB)
 ```
 
+_Note_: In current form, after deployment, your API is public and can be invoked by anyone. For production deployments, you might want to configure an authorizer. For details on how to do that, refer to [`httpApi` event docs](https://www.serverless.com/framework/docs/providers/aws/events/http-api/).
+
 ### Invocation
 
-After successful deployment, you can invoke the deployed function by using the following command:
+After successful deployment, you can call the created application via HTTP:
 
-```bash
-serverless invoke --function hello
+```
+curl https://xxxxxxx.execute-api.us-east-1.amazonaws.com/
 ```
 
-Which should result in response similar to the following:
+Which should result in the following response:
 
 ```json
-{
-  "statusCode": 200,
-  "body": "{\"message\":\"Go Serverless v4.0! Your function executed successfully!\"}"
-}
+{ "message": "Hello from root!" }
 ```
 
 ### Local development
 
-The easiest way to develop and test your function is to use the Serverless Framework's `dev` command:

 Now you can invoke the function as before, but this time the function will be executed locally. Now you can develop your function locally, invoke it, and see the results immediately without having to re-deploy.
 
 When you are done developing, don't forget to run `serverless deploy` to deploy the function to the cloud.
-
-## Monitoring and Troubleshooting
-
-### Logs
-
-To view the logs of the deployed function, you can use the following command:
-
-```bash
-serverless logs -f hello
-```
-
-You can also use the `--tail` flag to view the logs in real time:
-
-```bash
-serverless logs -f hello --tail
-```

`1-3`: **Consider adding more common entries to .gitignore**

The current .gitignore file is quite minimal. For Node.js projects, it's usually beneficial to include entries for:
- Environment files (.env, .env.*)
- Log files (logs, *.log)
- OS-specific files (.DS_Store, Thumbs.db)
- IDE configurations (.idea, .vscode)
- Test coverage reports (coverage)

<summary>❌ Incorrect review comment</summary>

**Verify bcryptjs version compatibility**

The specified version `^3.0.2` for bcryptjs seems unusual as the latest stable version is around 2.4.3. This might be a typo or an incorrect version specification.

---

🌐 Web query:

```web
What is the latest version of bcryptjs npm package?
```

💡 Result:

The latest version of the `bcryptjs` npm package is **3.0.2**, published 17 days ago as of the current date (March 7, 2025) [1][2]. This version maintains compatibility with the original `bcrypt` library while offering a pure JavaScript implementation with zero dependencies and TypeScript support [1].

Key details about `bcryptjs@3.0.2`:
- Security: Passed all security checks with no detected vulnerabilities [2]
- Maintenance: Actively maintained with recent updates
- Compatibility: Works in both Node.js and browser environments [1]
- Installation: Available via npm, CDN, or direct download [1]

The package receives over 306 million monthly downloads and is used by 4,050+ dependent projects, making it a widely trusted solution for password hashing in JavaScript applications [2][5]. For new projects, developers should use the installation command:

```bash
npm install bcryptjs
```

**Bcryptjs Version is Valid**

After verifying the npm registry, version **3.0.2** is indeed the latest of the bcryptjs package. The dependency specification in `api/package.json` using `"bcryptjs": "^3.0.2"` is correct and up-to-date. Please disregard the concern raised in this review comment.

<summary>api/README.md (2)</summary>

`2-3`: **Title and description updates look good.**

These clearer descriptions will help future contributors quickly understand the project scope.

<summary>api/handler.js (3)</summary>

`1-4`: **Clean import statements.**

The introduced libraries and services fit naturally into the Express-based architecture.

`69-73`: **404 route configuration looks correct.**

Using a dedicated route for 404 handling is a good practice for Express apps.

`19-22`: **Add TODOs with implementation details**

Since this is a placeholder implementation, consider adding specific TODOs that outline what the actual implementation will include.

**Verify Bcryptjs Version Upgrade**

We've verified via the npm registry that bcryptjs version `3.0.2` is indeed published alongside the older 2.x releases. Historically, the stable version was in the 2.x range; however, versions from `3.0.0` through `3.0.2` are now available. Please confirm that upgrading to `3.0.2` is intentional and that any associated changes or compatibility impacts are duly noted.

**Auto-generated file should not be committed**

This appears to be an auto-generated file from the Serverless Framework. It's generally a best practice not to commit auto-generated files to version control as they can change frequently and make the commit history noisy.


Consider adding `.serverless/` directory (including all its contents) to your `.gitignore` file instead of just the `.serverless` entry, which might only ignore a file named exactly `.serverless`.

```diff
node_modules
-.serverless
+.serverless/
```

**Add input validation and error handling for account creation**

The current implementation is a placeholder, which is fine for initial setup. However, it should be enhanced with:

1. Input validation for email format and password strength
2. Error handling for various failure scenarios
3. More detailed return types for better TypeScript integration


```diff

**Add TypeScript dependencies and configuration**

Since the project uses TypeScript (account.ts), you should add TypeScript and related dependencies.


```diff
 "dependencies": {
   "bcryptjs": "^3.0.2",
   "express": "^4.19.2",
   "serverless-http": "^3.2.0"
 },
+"devDependencies": {

+},
+"scripts": {
+  "build": "tsc",
+  "dev": "ts-node server.ts",
+  "start": "node dist/server.js"
+},
```

Also, create a basic `tsconfig.json` file in the api directory to configure TypeScript.

**Use the hashed password in an await-based flow.**

Currently, the code never awaits the bcrypt callback nor uses the hashed password, which could result in storing plaintext passwords and potential errors. To fix this, switch to `async/await` and replace the callback approach:


```diff
app.post("/register", async (req, res) => {
  try {
    const { email, password } = req.body;
    if (!email || !password) {
      return res.status(400).json({ error: "Email and password are required" });
    }

    const SALT_ROUNDS = 12;
-   bcrypt.genSalt(SALT_ROUNDS, (err, salt) => {
-     if (err) {
-       throw err;
-     }
-     bcrypt.hash(password, salt, (err, hash) => {
-       if (err) {
-         throw err;
-       }
-       console.log(hash);
-     });
-   });
-
    // Use async/await for hashing
+   const salt = await bcrypt.genSalt(SALT_ROUNDS);
+   const hash = await bcrypt.hash(password, salt);

-   const { verificationCode } = await createAccount(email, password);
+   // Pass the hashed password to createAccount
+   const { verificationCode } = await createAccount(email, hash);

    await sendVerificationEmail(email, verificationCode);

    return res.status(201).json({
      message: "User registration successful",
    });
  } catch (error) {
    console.error('Registration error:', error);
    return res.status(500).json({ error: "Internal server error" });
  }
});
```

**Strengthen password requirements for security**

A 4-character minimum for passwords is extremely weak by modern security standards. Consider increasing the minimum length to at least 8 characters and adding complexity requirements.

```diff
-    if (!password || password.length < 4) {
-      return { error: 'Password must be at least 4 characters long' };
+    if (!password || password.length < 8) {

## Walkthrough
This pull request restructures the API implementation from a single serverless function into a full Express.js application. The changes include major updates to routing and error handling, a revamped README describing the new functionality, and updates to deployment configuration in the serverless configuration file. Additionally, several ignore entries in the gitignore files have been removed, a new package.json has been added specifying dependencies for Express, and new account management services have been introduced.

| `api/.gitignore`, `.gitignore`                            | In `api/.gitignore`, removed entries for environment variables, logs, OS, IDE files, node_modules, etc., leaving only `.serverless`; new root `.gitignore` added to ignore `node_modules` and `.serverless`. |
| `api/README.md`                                           | Updated title, description, and deployment instructions to reflect the shift from a generic NodeJS function to a Node Express API; removed monitoring section. |
| `api/handler.js`                                          | Refactored the code to initialize an Express app with routes (`GET /`, `GET /hello`, `POST /register`); added password hashing, error handling, and integration with account services. |
| `api/package.json`                                        | New file created defining the module as "api" with dependencies on `express`, `bcryptjs`, and `serverless-http`, using Yarn as the package manager.      |
| `api/serverless.yml`                                      | Removed the legacy `hello` function and added a new `api` function with the handler set to `handler.handler`; simplified region/stage configuration.     |
| `api/services/account.ts`                                 | New file added containing asynchronous functions `createAccount` and `sendVerificationEmail` with input validations and error handling.                    |

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=vested-ai/api&utm_content=2):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
- Add `@coderabbitai` anywhere in the PR title to generate the title automatically.

### CodeRabbit Configuration File (`.coderabbit.yaml`)

- You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository.
- Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information.
- If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json`

### Documentation and Community
