Walkthrough

This pull request introduces modifications across multiple files. A new entry for .idea was added to the .gitignore to prevent IDE files from being tracked. The example server code has been simplified by removing an intermediary SSE server creation function and consolidating flag parsing. Additionally, the SSE server implementation was refactored to use a functional options pattern, adding configurable endpoint fields along with corresponding option functions. Test cases were updated to reflect the new server configuration approach.

Changes

File(s)	Change Summary
.gitignore	Added an entry for .idea to prevent tracking of IDE configuration files.
examples/everything/main.go	Removed the ServeSSE function and replaced its usage with a direct call to NewSSEServer; consolidated flag parsing for the transport type.
server/sse.go	Updated the SSEServer struct by adding messageEndpoint and sseEndpoint fields; modified NewSSEServer to accept variadic options; introduced option functions (WithBaseURL, WithMessageEndpoint, WithSSEEndpoint, WithHTTPServer).
server/sse_test.go	Updated tests to utilize the new configuration pattern for SSEServer, changing instantiation to use functional options. Minor formatting adjustments made.

server/sse.go (6)

23-32: Good expansion of the SSEServer struct for configurable endpoints

The struct has been enhanced with configurable messageEndpoint and sseEndpoint fields, which removes hardcoded paths and improves flexibility. The documentation has also been improved to better describe the purpose of the server.

---

34-63: Well-implemented functional options pattern

The implementation of the functional options pattern is clean and follows best practices:

• Clear Option type definition
• Well-documented option functions with descriptive names
• Each option function properly encapsulates a single configuration aspect

This approach provides great flexibility while maintaining backward compatibility.

---

65-79: Good constructor implementation with sensible defaults

The updated NewSSEServer function properly:

• Sets sensible defaults for endpoints
• Applies all provided options sequentially
• Maintains a clean interface despite the increased configuration options

The use of variadic options makes the API both flexible and readable for consumers.

---

173-177: Good usage of the configured messageEndpoint

The message endpoint URL is now properly constructed using the configurable endpoint field instead of a hardcoded value.

---

302-306: Good routing implementation with configurable endpoints

The route handling now correctly uses the configurable endpoint fields, which makes the server more flexible and removes hardcoded paths.

---

82-84:

✅ Verification successful

Verify that NewTestServer works as expected

The test server implementation has been simplified, but no longer sets the base URL through options. Please verify that this doesn't impact test functionality, as the base URL is now set directly after server creation.

---

🏁 Script executed:

#!/bin/bash
# Check if any tests might be relying on the baseURL being set during NewSSEServer construction
rg -A 3 -B 3 "NewTestServer" --type go

Length of output: 1278

Test Server Functionality Verified

After checking the usage in test files (e.g., in client/sse_test.go and server/sse_test.go), it appears that removing the option-based base URL setting in NewTestServer is not impacting test functionality. The base URL is still correctly configured after server creation, and the tests that rely on NewTestServer work as expected.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• 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.

🧹 Nitpick comments (7)

examples/everything/main.go (1)

424-424: Optional: Consider specifying custom options.

When creating the SSE server, you might want to pass configuration options (e.g., WithBaseURL) to better control endpoints or logging. As it stands, the default values suffice, but consider if your application needs more explicit settings.

server/sse_test.go (3)

237-237: Consistency check.

This instantiation duplicates the same base URL used above. Consolidating it in a shared helper or constant could reduce repetition across your tests.

---

291-291: Consistent test pattern.

Again, the same functional option is used, which is fine for clarity. If multiple URLs are tested, consider centralizing them for maintainability.

---

400-400: Assert contextual information in test.

You verify the status code for an accepted request. This is appropriate for the SSE-based workflow. As an optional improvement, consider also verifying any expected response body content when feasible.

server/sse.go (3)

23-25: Documentation improvement.

The description for SSEServer is concise and clear. Consider briefly mentioning usage scenarios or typical flows (e.g., how to set up endpoints and send events) for more context.

---

37-42: Base URL setting.

This option is straightforward. If your SSE server also supports relative endpoints, consider validating or normalizing the base URL input.

---

44-49: Message endpoint setter.

No issues here. Just be mindful of leading/trailing slashes, as normalizing them can prevent accidental double slashes in paths.

🔇 Additional comments (9)

examples/everything/main.go (1)

417-417: Consider consolidating or aliasing flags.

You declare two flags (“-t” and “-transport”) that set the same variable. This can be intentional for aliasing, but it might also cause confusion for users if it's unintentional. Ensure that both flags are truly needed, or remove one to avoid confusion.

server/sse_test.go (2)

19-19: Good use of functional options.

Using WithBaseURL("http://localhost:8080") during tests is clear and aligns with the flexible options approach in your SSE server.

---

339-339: Using defaults without options.

Here, you're testing the default server configuration. This is a good pattern to ensure coverage of the no-options scenario.

server/sse.go (6)

26-32: Sync.Map usage is acceptable.

Storing sessions in a sync.Map is fine for concurrency. However, ensure your code properly handles session lifecycle and potential memory growth. Consider bounding session durations or removing stale sessions.

---

34-35: Functional options pattern is well-established.

Defining an Option type is a clean approach. This makes the code more configurable and readable.

---

51-56: SSE endpoint setter.

Similarly, be aware of possible conflicts if two endpoints are set to the same path. Consider warnings or checks if that ever occurs.

---

58-63: Passing custom HTTP server.

This is helpful for advanced use cases (TLS, custom middlewares). It’s good that you fall back to your own server if none is supplied.

---

65-79: Comprehensive constructor.

The default endpoints (“/sse” and “/message”) are sensible and align with typical SSE usage. The functional option loop is cleanly applied.

---

305-307: ServeHTTP path handling.

The new switch cases correctly delegate to handleSSE and handleMessage using configured endpoints. Ensure that these match any user-configured routes if multiple SSE servers or prefix-based routing is used elsewhere.
