packages/templates/clients/js/websocket/components/Constructor.js (1)
6-14: Consider consistent indentation in template stringsThe indentation inside your template string is inconsistent with the JSX structure. Consider either using consistent indentation or using a tool like Prettier to maintain code formatting.
packages/templates/clients/js/websocket/components/CloseConnection.js (1)
7-13: Consider removing or conditionally logging console messagesThe
console.logstatement on line 11 might not be desired in a production environment. Consider either:
- Removing it
- Making it conditional based on a debug/development flag
- Using a more sophisticated logging mechanism
This would make the client more suitable for production use.
packages/templates/clients/js/websocket/components/SendEchoMessage.js (1)
1-17: Component structure looks good, but nested Text components seem redundantThe
SendEchoMessagecomponent is well-structured, but there's unnecessary nesting ofTextcomponents. A singleTextcomponent should be sufficient to render the string content.export function SendEchoMessage () { return ( - <Text> <Text> { ` // Method to send an echo message to the server sendEchoMessage(message) { this.websocket.send(JSON.stringify(message)); console.log('Sent message to echo server:', message); }` } </Text> - </Text> ); }packages/templates/clients/js/websocket/components/RegisterErrorHandler.js (1)
1-20: Component structure looks good, but nested Text components are redundantThe
RegisterErrorHandlercomponent is well-structured and correctly implements error handler registration. However, the nestedTextcomponents are unnecessary.export function RegisterErrorHandler () { return ( - <Text> <Text> { ` // Method to register custom error handlers registerErrorHandler(handler) { if (typeof handler === 'function') { this.errorHandlers.push(handler); } else { console.warn('Error handler must be a function'); } }` } </Text> - </Text> ); }packages/templates/clients/js/websocket/components/RegisterMessageHandler.js (1)
1-20: Simplify component structure by removing redundant Text wrapperSimilar to the other components, there's unnecessary nesting of
Textcomponents that should be simplified.export function RegisterMessageHandler () { return ( - <Text> <Text> { ` // Method to register custom message handlers registerMessageHandler(handler) { if (typeof handler === 'function') { this.messageHandlers.push(handler); } else { console.warn('Message handler must be a function'); } }` } </Text> - </Text> ); }packages/templates/clients/js/websocket/components/Connect.js (1)
1-52: Simplify component structure by removing redundant Text wrapperSimilar to the other components, there's unnecessary nesting of
Textcomponents that should be simplified.export function Connect ({ title }) { return ( - <Text> <Text> { ` // Method to establish a WebSocket connection connect() { return new Promise((resolve, reject) => { this.websocket = new WebSocket(this.url); // On successful connection this.websocket.onopen = () => { console.log(`Connected to ${title} server`); resolve(); }; // On receiving a message this.websocket.onmessage = (event) => { console.log('Message received:', event.data); this.messageHandlers.forEach(handler => { if (typeof handler === 'function') { this.handleMessage(event.data, handler); } }); }; // On error first call custom error handlers, then default error behavior this.websocket.onerror = (error) => { if (this.errorHandlers.length > 0) { // Call custom error handlers this.errorHandlers.forEach(handler => handler(error)); } else { // Default error behavior console.error('WebSocket Error:', error); } reject(error); }; // On connection close this.websocket.onclose = () => { console.log(`Disconnected from ${title} server`); }; }); }` } </Text> - </Text> ); }packages/templates/clients/js/websocket/template/client.js.js (2)
14-14: Consider adding a descriptive function name.You might consider giving a more descriptive name (e.g.,
WebSocketClientTemplate) rather than using the default export function directly. This can improve clarity when referencing it elsewhere.-export default function ({ asyncapi, params }) { +export default function WebSocketClientTemplate({ asyncapi, params }) {
28-30: Consider a cosmetic line break for readability.Adding a blank line after declaring the class can make the generated code more readable.
<Text> - {`class ${clientName} {`} + {`class ${clientName} {\n`} </Text>

packages/templates/clients/js/websocket/components/ModuleExport.js (1)
1-11: Clean implementation of the ModuleExport componentThe component is well-structured and follows React best practices. It has a single responsibility of generating the module export statement and appropriately uses the
Textcomponent from the SDK for rendering.packages/templates/clients/js/websocket/template/client.js.js (7)
3-3: Looks good!The new
FileHeaderInfoimport helps ensure that metadata is clearly displayed.
5-12: Solid modular approach.These newly introduced component imports (e.g.,
Constructor,Connect, etc.) improve code organization by separating distinct client functionalities into self-contained modules. This enhances readability and maintainability.
27-27: No issues with the<Requires />usage.This centralizes needed imports for the generated client.
31-37: Great modularization of client methods.Switching to individual components (
Constructor,Connect,HandleMessage, etc.) fosters better code clarity and reusability.
38-40: Neat final bracket structure.Closing the class block in its own
<Text>node cleanly separates it from the generated methods. No concerns here.Also applies to: 42-42
43-43: Clean export declaration.Using the
<ModuleExport clientName={clientName} />component is consistent with the new modular architecture.
44-45: File closure looks good.No issues with the final
</File>and);statements.

🛠️ Refactor suggestion
Remove unnecessary nested Text component
There's an unnecessary nesting of Text components. The outer Text component (line 5) wraps another Text component (line 6) without adding any value.
export function HandleMessage () {
return (
- <Text>
<Text>
{
` // Method to handle message with callback
handleMessage(message, cb) {
if (cb) cb(message);
}`
}
</Text>
- </Text>
);
}📝 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.

@derberg I add this Text because of extra spacing i.e new line between all the functions of class. But ok maybe I will remove extra from all and rather update snapshots. wdyt?

💡 Verification agent
🧩 Analysis chain
Validate server existence.
If params.server is unspecified, server may be undefined, leading to potential runtime errors. Ensure that the server key is always provided and valid.
🏁 Script executed:
#!/bin/bash
# Description: Confirm that 'params.server' is always set in the code/configuration.
rg -A 5 "params\.server"Length of output: 3364
Action Required: Validate 'params.server' Exists
The current implementation in packages/templates/clients/js/websocket/template/client.js.js retrieves the server using:
const server = asyncapi.servers().get(params.server);There is no check ensuring that params.server is provided. If it happens to be undefined, this can lead to runtime errors when subsequently calling getServerUrl(server) and elsewhere.
Recommendations:
- Add a validation check: Before accessing the server, confirm that
params.serveris defined. For example:if (!params.server) { throw new Error('The server parameter is required.'); } const server = asyncapi.servers().get(params.server);
- Review similar usage in other template files: Ensure that any place using
params.server(such as in the README template) performs a similar validation.

@derberg I didn't make any changes in this as well originally also no checks where written for params. I am not sure that should we throw Error from a template component? wdyt? We also then need to add same check in README.md.js template.

yeah, extra not related effort, @Adi-204 please create an issue to address it. Without server the template will not work, so we for use need to use hasServers function (if there is such) and if there is non, we need to discuss if we want to throw error or actually suggest a workaround (it is possible to have custom parameters in templates) - anyway, please create an issue

@Adi-204 you're getting some good pointers from rabbit, please adjust accordingly |

@derberg few questions before commit regarding improvements suggested in Nitpick comments -
It don't think this 2 are very important. wdyt? |
There was a problem hiding this comment.
maybe this should also be a separate component for clarity:
<Text>
{`class ${clientName} {`}
</Text>
<Constructor serverName={serverName} />
<Connect title={title} />
<RegisterMessageHandler />
<RegisterErrorHandler />
<HandleMessage />
<SendEchoMessage />
<CloseConnection />
<Text>
{
`}`
}
</Text>
and yeah, best if generated code is clean, aligned and readable, so adding new lines makes sense, just not with \n but use props from Text component
all props view <Text indent={size} type={type} newLines={newLines}>
so you're looking for <Text newLines={2}>
|
and yes, snapshots can be edited - nothing bad happens because they can be reviewed on the PR level and we can validate if the change is good - this is what they are for |

packages/templates/clients/js/websocket/components/ClientClass.js (1)
11-32: Well-structured component implementationThe ClientClass component cleanly encapsulates the JavaScript class generation using a component-based approach. This is a significant improvement over the previous template string-based implementation, making the code more maintainable and modular.
However, there's inconsistent indentation in the template string at lines 25-27 compared to the JSX structure.

1-10: Clean import structureThe imports are well-organized, importing the required Text component from the SDK and all the necessary client-related components. This demonstrates good componentization of the previously monolithic client code.
11-32: Verify component compositionThe component structure is logical and well-organized. Each method of the original WebSocket client has been properly extracted into its own component, which are now composed together in this parent component.
packages/templates/clients/js/websocket/template/client.js.js (3)
1-5: Clean import structure with new componentsThe imports have been updated to include the new ClientClass component, while maintaining the existing imports for helper functions and other components.
7-13: Improved variable extraction and clarityThe code now explicitly extracts
clientNameandserverNameusing helper functions, which improves readability and makes the dependencies clearer. This is a good practice for maintainability.Note: There's still an unresolved issue regarding validation of
params.serverexistence, but per the previous review comments, this will be addressed in a separate issue.
20-22: Successful implementation of componentizationThe refactoring to use the ClientClass component instead of the inline template string represents a successful implementation of componentization. This change significantly improves code organization and maintainability.

@derberg I completely forgot about TODO mentioned 😅 should we remove it? And the additional Nitpick comments. |

one last thing, I see in few places you do something like below adding indent "manually". please instead do |

5-48: Consider maintaining consistent indentation within the template stringWhile the
<Text indent={2}>handles the initial indentation, there's manual indentation within the template string. For consistency, consider using either a consistent indentation approach throughout the template or a tool like Prettier to format the code.

1-51: Good componentization effort with a clean approachThis component is well-structured and follows a clean approach to generating WebSocket connection code. The use of the
Textcomponent with appropriate indentation settings is a good practice, as suggested in the PR comments.
14-14: Template string interpolation issue noted in previous reviewsThere was a previous discussion about the template string interpolation here. I note that this was intentionally kept as is with single quotes, as the code is generating a template string that will be interpolated at runtime, not during component rendering.
43-43: Template string interpolation issue noted in previous reviewsSame template string interpolation pattern as line 14, which was previously discussed and intentionally kept as is with single quotes.

1-50: The component structure looks good, but consider improving indentation.The
Connectcomponent is well-organized with appropriate separation of WebSocket event handlers. The use of theTextcomponent for code generation is appropriate.Consider maintaining consistent indentation within the template string to match the JSX structure, making the code more readable. The
indent={2}prop properly handles the initial indentation, but the internal indentation could be more consistent.
31-39: Consider adding error type checking for better error handling.The error handling mechanism works, but you might want to add more specific error type checking for better debugging and user feedback.
this.websocket.onerror = (error) => { if (this.errorHandlers.length > 0) { // Call custom error handlers this.errorHandlers.forEach(handler => handler(error)); } else { // Default error behavior - console.error('WebSocket Error:', error); + const errorMessage = error.message || 'Unknown WebSocket error'; + console.error(`WebSocket Error: ${errorMessage}`); } reject(error); };
