🧹 Nitpick comments (6)
capacitor-plugin-socket/src/definitions.ts (2)
1-6: Consider supporting binary data payloads.
Raw TCP sockets often exchange binary data. Currentlysend/receiveusestringfordata. You may want to useArrayBufferorUint8Array(or overloads) in the interface to handle binary payloads.
1-6: Add JSDoc comments for improved DX.
Annotating each method (connect,send,receive,disconnect) with JSDoc will surface signatures and parameter docs in editors.capacitor-plugin-socket/src/index.ts (2)
1-1: Specify the plugin interface generic.
Use the generic onregisterPluginfor full TypeScript type inference:const SocketPlugin = registerPlugin<SocketPlugin>('SocketPlugin', { … });
3-5: Add explicit iOS fallback.
Currently onlywebis defined. To avoid runtime errors on unsupported platforms, add aniosstub to import your web implementation:const SocketPlugin = registerPlugin<SocketPlugin>('SocketPlugin', { web: () => import('./web').then(m => new m.SocketPluginWeb()), ios: () => import('./web').then(m => new m.SocketPluginWeb()), });capacitor-plugin-socket/src/web.ts (1)
5-23: Use the WebPlugin’s unimplemented helper.
Rather thanconsole.log+ default returns, callthis.unimplemented()for a standardized unimplemented error:async connect(...) { - console.log('Web implementation does not support raw TCP sockets.', options); - return { success: false }; + return this.unimplemented('Raw TCP sockets are not supported on web.'); }Apply similarly for
send,receive, anddisconnect.android/app/src/main/java/betaflight/configurator/plugin/SocketPlugin.java (1)
1-72: Add thread safety and consider using AsyncTask or ExecutorService.The current implementation performs network operations on the main thread and lacks thread safety:
- Network operations on the main UI thread can cause ANR issues
- No proper handling of concurrent method calls
- Consider using background threads for socket operations
While Capacitor's
executeAsynchelps with background execution, you may want to implement a more robust threading strategy. Consider:
- Using Android's ExecutorService for managing a thread pool
- Implementing proper synchronization for shared resources
- Adding cancellation support for long-running operations
Additionally, consider implementing timeout handling for all socket operations and add proper documentation for users of this plugin, explaining:
- When to use SSL vs. raw sockets
- How to handle timeouts and connection failures
- Best practices for error handling

19-33: Improve security and robustness inconnectmethod.The connect method has several issues that could lead to application crashes or security vulnerabilities:
- No input validation
- No check for existing connections
- Using an unencrypted socket (security concern)
- Operations run on the main thread (may freeze UI)
- No socket timeout
- No resource cleanup on failure

35-47: Add state validation to send method.The send method should check if there's an active connection before attempting to write data. It also runs on the main thread and lacks input validation.
49-59: Potential blocking operation in receive method.The
readLine()method blocks indefinitely until data with a line terminator is available or the connection is closed, which can cause the app to freeze.
61-72: Improve resource cleanup in disconnect method.The disconnect method only closes the socket but doesn't properly clean up all resources:
- Reader and writer aren't closed
- Class fields aren't reset
- No state tracking
1-72: 🛠️ Refactor suggestionImplement a helper method for resource cleanup.
The class needs a helper method for closing resources consistently across all methods to avoid resource leaks and maintain proper state.
@PluginMethod public void disconnect(PluginCall call) { try { - if (socket != null) socket.close(); + closeResources(); + isConnected = false; JSObject ret = new JSObject(); ret.put("success", true); call.resolve(ret); } catch (Exception e) { call.reject("Disconnect failed: " + e.getMessage()); } } +/** + * Helper method to close all resources and clean up state + */ +private void closeResources() { + try { + if (reader != null) { + reader.close(); + reader = null; + } + if (writer != null) { + writer.close(); + writer = null; + } + if (socket != null) { + socket.close(); + socket = null; + } + } catch (IOException e) { + // Log but continue cleanup + Log.e("SocketPlugin", "Error closing resources", e); + } +}🧰 Tools

13-18: 🛠️ Refactor suggestionAdd connection state tracking.
The class lacks state management to track when a socket is connected. This is important for preventing operations on closed sockets and proper cleanup.
@CapacitorPlugin(name = "SocketPlugin") public class SocketPlugin extends Plugin { private Socket socket; private BufferedReader reader; private BufferedWriter writer; + private boolean isConnected = false;
51-52: 🛠️ Refactor suggestionMove network I/O off the main thread.
Reading from the socket on the main thread can cause UI freezes (ANR - Application Not Responding). Move this operation to a background thread.
@PluginMethod public void receive(PluginCall call) { + // Verify connection state first + if (socket == null || !isConnected) { + call.reject("Not connected to any server"); + return; + } + + // Use executeAsync to move this work off the main thread + executeAsync(() -> { try { String data = reader.readLine(); + if (data == null) { + // Connection closed by server + closeResources(); + isConnected = false; + call.reject("Connection closed by server"); + return; + } JSObject ret = new JSObject(); ret.put("data", data); call.resolve(ret); } catch (Exception e) { + closeResources(); + isConnected = false; call.reject("Receive failed: " + e.getMessage()); } + }); }

23-23:❓ Verification inconclusive
Consider using encrypted sockets for sensitive data.
The current implementation uses unencrypted sockets which could expose transmitted data to network eavesdropping. For sensitive information, consider using SSL/TLS sockets.

Evaluate encryption for SocketPlugin.java
The
SocketPlugincurrently opens an unencrypted TCP socket (java.net.Socket) on line 24 without any SSL/TLS layers. If this channel ever carries sensitive data (credentials, tokens, personal info), it would be exposed to eavesdropping.• File:

– No use ofSSLSocketorSSLContextdetectedPlease verify whether any sensitive information is sent over this socket. If so, replace
Socketwith anSSLSocket(or configure anSSLContext) to enable TLS encryption.🧰 Tools

receive()performs a blocking read on the UI thread
reader.readLine()can block indefinitely, risking ANR. Off-load to a background thread:executeAsync(() -> { try { String data = reader.readLine(); … } catch (…) { … } });Also verify connection state (
socket == null || !isConnected), and handlenullresults (server closed).🤖 Prompt for AI Agents
In android/app/src/main/java/betaflight/configurator/plugin/SocketPlugin.java around lines 88 to 96, the receive() method performs a blocking read on the UI thread using reader.readLine(), which can cause ANR issues. To fix this, wrap the readLine() call and subsequent logic inside an executeAsync() runnable to offload it to a background thread. Additionally, before reading, check if the socket is null or not connected and reject the call early if so. Also handle the case where readLine() returns null, indicating the server closed the connection, and reject the call accordingly.

In android/app/src/main/java/betaflight/configurator/plugin/SocketPlugin.java around lines 68 to 72, the send() method is currently executed on the main thread, which can cause UI freezes during large writes or network delays. To fix this, wrap the send operation inside an executeAsync(() -> { ... }) block to run it asynchronously off the main thread, similar to how receive() is handled. This will prevent UI blocking during socket writes.

112-134: UI-thread hopping for a simple log is unnecessary &getContext()may not exist
getContext().getActivity()is not part of the publicPluginAPI; usegetActivity()directly, or just:- // Log but continue cleanup - getContext().getActivity().runOnUiThread(() -> - Log.e("SocketPlugin", "Error closing resources", e)); + // Log but continue cleanup + Log.e("SocketPlugin", "Error closing resources", e);This also eliminates the need to obtain the main-thread handler.

In android/app/src/main/java/betaflight/configurator/plugin/SocketPlugin.java around lines 87 to 97, the receive method blocks the main thread by calling readLine() directly and does not check socket connection state, risking UI freeze and resource leaks. Fix this by first verifying socket is not null, not closed, and connected before reading. Move the blocking readLine() call inside an executeAsync block to avoid blocking the UI thread. Also, handle the case where readLine() returns null (indicating the peer closed the connection) by calling closeResources() to clean up properly.

24-62:❓ Verification inconclusive
Well-implemented connect method with security considerations.
The connect method has proper input validation, duplicate connection prevention, and runs network operations on a background thread. Setting a timeout is a good practice.
However, the socket communication is not encrypted, which could be a security concern if sensitive data is transmitted.
Consider using an
SSLSocketfor secure communication if sensitive data will be transmitted. If encryption is not required for your specific use case, add a comment explaining why.

Verify encryption requirements for socket communication
No references to passwords, tokens, credentials, or API keys were found in the Java codebase. If you are confident that only non-sensitive data is sent over this socket, please add a comment in SocketPlugin.java explaining why unencrypted communication is acceptable. If there is any chance you’ll transmit credentials or other sensitive information in the future, switch to an SSLSocket to ensure data is encrypted in transit.

1-166: 💡 Verification agent🧩 Analysis chain
Consider using encrypted socket communication for sensitive data.
The current implementation uses an unencrypted Socket, which could allow traffic interception by malicious actors.
🌐 Web query:
When should I use SSLSocket instead of Socket in Java?💡 Result:
You should use SSLSocket instead of Socket in Java when transferring sensitive data over insecure communication channels. The SSLSocket class provides critical security protections that regular Socket does not offer, making it essential for secure communications.
Security Protections Provided by SSLSocket
SSLSocket extends the basic Socket class but adds several important security layers through protocols like Secure Sockets Layer (SSL) and Transport Layer Security (TLS)[1][2]. These additional protections include:
Integrity Protection: SSL prevents modification of messages by active attackers, ensuring that data cannot be tampered with during transmission[1].
Authentication: SSLSocket provides peer authentication capabilities. In most implementations, servers are always authenticated, and clients can be authenticated when requested by servers[1][4].
Confidentiality: SSLSocket encrypts data being sent between client and server, protecting sensitive information such as financial data or personal information from eavesdropping by passive wiretappers[1].
Specific Use Cases
You should use SSLSocket rather than Socket in the following scenarios:
When handling sensitive data: Any application that deals with personal information, financial data, login credentials, or other confidential information[1].
For secure Remote Method Invocation (RMI): When using Java RMI, which depends on object serialization, serialized data must be protected in transit[1].
When communicating across untrusted networks: Any data transmitted over public networks like the internet should use secure sockets[1][5].
For compliance requirements: Many regulatory standards require secure communications for sensitive data transfers[1].
Implementation Comparison
Implementing SSLSocket involves a few more steps than using a regular Socket, but the security benefits are substantial. A basic SSLSocket implementation requires:
- Initializing an SSLContext
- Creating an SSLSocketFactory from the context
- Using the factory to create an SSLSocket
- Starting the SSL handshake process[5][6]
For example, client-side implementation requires:
// Initialize SSLContext SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(null, trustManagerFactory.getTrustManagers(), null); // Create SSLSocket SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory(); SSLSocket sslSocket = (SSLSocket) sslSocketFactory.createSocket("localhost", 8443); // Start SSL handshake sslSocket.startHandshake();While SSLSocket adds security, it's worth noting that it may introduce some performance overhead compared to plain Socket connections[3]. However, this trade-off is necessary and justified when security is a requirement.

Switch to SSLSocket for secure communications
The plugin currently opens a plain

connect(...):- socket = new Socket(ip, port); + // Initialize SSL context (e.g. TLSv1.2+) + SSLContext sslContext = SSLContext.getInstance("TLS"); + sslContext.init(null, /* custom TrustManagers if needed */ null, null); + SSLSocketFactory factory = sslContext.getSocketFactory(); + SSLSocket sslSocket = (SSLSocket) factory.createSocket(ip, port); + sslSocket.startHandshake(); + socket = sslSocket;Next steps:
- Configure a TrustManager/KeyManager if you need custom certificates or mutual auth.
- Verify hostname on the server certificate to avoid MITM attacks.
- Adjust timeouts and cipher suites as required by your security policy.

131-142: Consider executing disconnect on a background thread.While the disconnect implementation correctly cleans up resources, it runs on the calling thread which is likely the UI thread. Socket closure can be blocking.
@PluginMethod public void disconnect(PluginCall call) { - try { - closeResources(); - isConnected = false; - JSObject ret = new JSObject(); - ret.put("success", true); - call.resolve(ret); - } catch (Exception e) { - call.reject("Disconnect failed: " + e.getMessage()); - } + getBridge().getExecutor().execute(() -> { + try { + closeResources(); + isConnected = false; + JSObject ret = new JSObject(); + ret.put("success", true); + call.resolve(ret); + } catch (Exception e) { + call.reject("Disconnect failed: " + e.getMessage()); + } + }); }
144-167: Thorough resource cleanup implementation.The closeResources method properly:
- Closes all resources in the correct order
- Nullifies references to prevent memory leaks
- Updates connection state on failures
- Handles exceptions gracefully with logging
- Runs logging on the UI thread
Consider adding a writer.flush() before closing to ensure all buffered data is sent.
if (writer != null) { + writer.flush(); // Ensure all buffered data is sent writer.close(); writer = null; }
24-63:❓ Verification inconclusive
Consider using encrypted socket for sensitive data.
The implementation correctly validates inputs, prevents duplicate connections, and moves network operations to a background thread. The timeout setting is a good practice.
However, the code uses an unencrypted socket which could expose transmitted data to interception.
If your application transmits sensitive data, consider using SSLSocket instead:
- socket = new Socket(ip, port); + SSLSocketFactory factory = (SSLSocketFactory) SSLSocketFactory.getDefault(); + socket = (SSLSocket) factory.createSocket(ip, port);This would require adding these imports:
import javax.net.ssl.SSLSocket; import javax.net.ssl.SSLSocketFactory;
🏁 Script executed:
#!/bin/bash # Description: Check if secure communications are required elsewhere in the app # Check for SSL/TLS usage rg -A 2 "SSLSocket|SSLSocketFactory|TrustManager|KeyStore" --type java # Check for sensitive data patterns rg -A 2 "password|credential|token|key|secret|auth" --type javaLength of output: 138
Verify encryption requirements for Socket connections
File: android/app/src/main/java/betaflight/configurator/plugin/SocketPlugin.java
Lines: 24-63Ripgrep across the Java codebase didn’t detect any existing SSL/TLS usage (SSLSocketFactory, TrustManager, KeyStore, etc.) or common sensitive-data patterns (password, token, key, secret). Absence of evidence isn’t evidence of absence—if this plugin ever carries credentials or other sensitive information, you should consider switching to an SSLSocket:
- socket = new Socket(ip, port); + SSLSocketFactory factory = (SSLSocketFactory) SSLSocketFactory.getDefault(); + socket = (SSLSocket) factory.createSocket(ip, port);And add these imports:
import javax.net.ssl.SSLSocket; import javax.net.ssl.SSLSocketFactory;Please verify whether encrypted communication is required for your use case.

1-16: Well-structured package declarations and class documentation.The class is properly organized with appropriate imports and clear documentation that explains the plugin's purpose. The Capacitor plugin annotation is correctly set up.
19-22: Good field declarations with proper connection state tracking.The class fields are well-defined, including the boolean flag to track connection state. This will help prevent operations on closed sockets.
65-99: Thread-safe send implementation with proper validation.The send method implementation is robust with:
- Input validation
- Connection state verification
- Background thread execution
- Synchronized writer access
- Protocol framing with newline
- Proper error handling and resource cleanup
This addresses all the concerns from previous reviews.
101-129: Excellent non-blocking receive implementation with peer disconnection handling.The receive method correctly:
- Validates connection state before proceeding
- Executes read operations on a background thread
- Handles the case when a peer closes the connection (null readLine return)
- Properly manages resources on exceptions
- Returns data in the correct format
This addresses all previous concerns about blocking reads and error handling.

150-160:flush()in cleanup can block – usually unnecessary beforeclose()
BufferedWriter.close()already performs an implicit flush. Callingflush()first can add latency or block during error paths (e.g. lost network). You can safely drop it and rely onclose().
86-88: Assumed protocol framing – maybe make configurableAppending
newLine()hard-codes a text-based framing scheme. If binary protocols or CRLF expectations arise, consider exposing a boolean/enum option (e.g.terminator) so callers can pick the delimiter, or document the newline requirement clearly.

221-231: Consider separating resource closing into individual methods.While the current implementation works well, having individual methods for closing each resource type (reader, writer, socket) could improve readability and maintainability.

19-24: Well-designed Capacitor plugin structure with clear documentation.The class is properly annotated with
@CapacitorPluginand has clear documentation explaining its purpose and features. The plugin name matches the class name, making it consistent and easy to understand.
27-40: Excellent use of constants for error messages and settings.Using string constants for error messages enhances maintainability and consistency throughout the codebase. The connection settings constants are also well-defined with appropriate names and values.
41-56: Good use of enum and thread-safe fields.The
ConnectionStateenum provides a clear state model, and the thread-safety approach usingAtomicReferenceandReentrantLockis appropriate for a multi-threaded environment where socket operations run on background threads.
107-142: Good implementation of asynchronous send operation with thread safety.The method correctly validates input, checks connection state, and performs I/O operations asynchronously on a background thread with proper synchronization and error handling. The use of
truncateForLogis a nice touch to prevent log pollution.
144-169: Appropriately handling null response in receive method.The receive method correctly detects when the connection is closed by the peer (when
readLine()returns null) and handles this case properly by transitioning to an error state and cleaning up resources.
171-204: Robust disconnect implementation with proper state management.The disconnect method is well-implemented with state validation, thread safety, and proper resource cleanup. It also handles the case where the socket is already disconnected, avoiding unnecessary operations.
206-219: Excellent resource cleanup in handleOnDestroy.The override of
handleOnDestroyensures that resources are properly cleaned up when the plugin is destroyed, preventing resource leaks. The use of locks ensures that cleanup operations don't conflict with ongoing operations.
233-244: Good centralized error handling approach.The
handleCommunicationErrormethod centralizes error handling logic, making the code more maintainable and consistent. It appropriately transitions state, cleans up resources, and logs errors.
246-255: Well-implemented helper methods.The helper methods for state comparison and log truncation are well-implemented. The
truncateForLogmethod is a particularly nice touch that prevents log pollution when dealing with large data payloads.

123-130: Optional: capturewriterreference outside the critical section
writeris dereferenced inside thewriterLocksection. Capturing a local reference at the top of the task and re-checking it avoids a possibleNullPointerExceptionif another thread nullswriterbetween the outer guard (l. 123) and thesynchronizedblock, and removes an extra volatile read inside the loop.BufferedWriter localWriter = writer; if (localWriter == null || state.get() != ConnectionState.CONNECTED) { … } synchronized (localWriter) { localWriter.write(data); … }
258-263: Nit: promote magic number to astatic finalconstant
maxLen = 100is a hard-coded value that governs log truncation. Exposing it as a constant (e.g.LOG_TRUNCATE_LIMIT) at the top of the file improves discoverability and makes future adjustments easier.- final int maxLen = 100; + final int maxLen = LOG_TRUNCATE_LIMIT;
54-57: Thread-visibility of non-atomic fields
socket,reader, andwriterare accessed from multiple threads. Although most mutations happen undersocketLock/writerLock, plain reads occur in guards such asif (reader == null) …Without
volatileor always synchronising on the same lock, there is a (small) risk of reading a stale value on weakly-ordered CPUs. Declaring these fieldsvolatile(or always reading them under their respective locks) would provide a simple happens-before guarantee.
64-73: Minor: stricter IP/hostname validationCurrently only a non-empty string check is performed. If you anticipate malformed inputs (e.g.
"999.999.999.999"or hostnames with spaces), consider validating the supplied address withInetAddressValidator(from Apache Commons Validator) or a regex before attempting to connect.
This is low priority but can provide clearer error messages to callers.

The connect method handles most cases well, but there's an issue in the error handling path:
When a connection fails, the state is set to ERROR (line 96) but never reset to DISCONNECTED, which will prevent future reconnection attempts since the connect method is guarded by a check that requires the DISCONNECTED state (line 74).

19-56: Well-structured class design with strong thread safety foundations.The class design demonstrates excellent engineering practices:
- Comprehensive Javadoc explaining the plugin's purpose
- Well-defined constants for error messages and connection settings
- Proper use of enum for connection state representation
- Thread-safe state management with AtomicReference
- Synchronization using ReentrantLocks for potentially concurrent operations
The thread safety approach using both atomic references and explicit locks is particularly well-implemented, providing protection against race conditions while allowing concurrent operations when safe.
107-142: Strong implementation of send method with proper validation and thread safety.The send method implementation is excellent:
- Input validation before proceeding
- Connection state verification
- Double-checking connection state in the worker thread to prevent race conditions
- Using a dedicated lock for write operations
- Logging with data truncation to avoid excessive logs
- Proper error handling with centralized error handling method
The implementation correctly uses newLine() after writing data, which is important for many text-based protocols.
144-169: Well-implemented receive method with proper handling of connection closure.The receive method implementation handles all the important edge cases:
- Initial state validation
- Background thread execution to avoid blocking UI
- Detection of connection closure by remote peer (null return from readLine)
- Proper error handling and resource cleanup
- Concise logging with data truncation
The null check on line 155 is particularly important as it correctly detects when the connection has been closed by the peer.
171-204: Robust disconnect implementation with proper state management.The disconnect method correctly:
- Handles the case when already disconnected
- Uses atomic state transition
- Executes resource cleanup on a background thread
- Properly synchronizes with socket lock
- Transitions to disconnected state after successful cleanup
- Handles errors and provides appropriate error messaging
The implementation is thorough and follows best practices for resource cleanup and state management.
206-255: Excellent resource management and helper methods.The resource management and helper methods show careful attention to detail:
- handleOnDestroy correctly cleans up resources during plugin lifecycle events
- closeResourcesInternal handles each resource independently with individual try-catch blocks
- handleCommunicationError centralizes error handling logic
- compareAndSetState provides atomic state transitions
- truncateForLog cleverly limits logged data length to avoid excessive logging
The implementation of closeResourcesInternal is particularly strong, as it handles each resource separately and ensures they are all nulled out afterward to prevent reuse of closed resources.

1-29: Consider enhancing error messages for better web debugging.While the current implementation is correct, you might consider providing more specific error messages for each method or using a constant for the common error message to improve maintainability.

1-3: Appropriate imports for the plugin implementation.The imports are correctly set up, including the WebPlugin base class from Capacitor core and the SocketPlugin interface from the local definitions file.
4-4: Correct class definition with proper inheritance.The class properly extends WebPlugin and implements the SocketPlugin interface, following Capacitor's plugin architecture pattern.
5-8: Connect method correctly implements stub behavior.The connect method appropriately logs that web doesn't support TCP sockets and returns a failure response, matching the interface contract.
10-13: Send method correctly implements stub behavior.The send method appropriately logs that web doesn't support TCP sockets and returns a failure response, adhering to the interface contract.
15-18: Receive method correctly implements stub behavior.The receive method appropriately logs that web doesn't support TCP sockets and returns an empty data string, matching the interface contract.
20-23: Disconnect method correctly implements stub behavior.The disconnect method appropriately logs that web doesn't support TCP sockets and returns a failure response, matching the interface contract.
25-28: GetStatus method correctly implements stub behavior.The getStatus method appropriately logs that web doesn't support TCP sockets and returns a disconnected state, properly implementing the interface contract.
