🧹 Nitpick comments (8)
build/build-package.sh (3)
1-2
: Shebang and Robust Execution
The script begins correctly with a shebang. Consider adding aset -e
immediately after the shebang (e.g., on line 2) to ensure the script exits on any error. This makes the build process more robust.
5-16
: Explicit Copy Commands for Build Packaging
The series ofcp
commands clearly copy the necessary directories and files (such asview
,etc
,Setup
,Model
, etc.) to the temporary directory. While this approach is clear, consider refactoring these repetitive commands into a loop or helper function if you plan to extend the list in the future to improve maintainability.
18-18
: Zip Packaging Command
The use of the zip command with maximum compression is straightforward and works well for packaging. For enhanced reliability, consider adding error checking or logging to confirm that the zip archive (tawkmagento2.zip
) is successfully created.Controller/Adminhtml/StoreWidget/Index.php (1)
132-136
: Security-first approach forjsApiKey
.Returning
JS_API_KEY_NO_CHANGE
if the key is set helps avoid leaking the real key value. Consider using atrim()
check in case of accidental whitespace, but otherwise this is a good practice.-if (!empty($jsApiKey)) { +if (!empty(trim($jsApiKey))) { $jsApiKey = ConfigInterface::JS_API_KEY_NO_CHANGE; }view/frontend/web/js/tawk-embed.js (1)
19-21
: Potential error ifvisitor
is undefined.Accessing
visitor.hash
without verifyingvisitor
might cause a TypeError. Consider nesting this inside the existingif (visitor)
check.-if (visitor.hash) { +if (visitor && visitor.hash) { window.Tawk_API.visitor.hash = visitor.hash; }view/adminhtml/web/css/tawk-widget-select.css (1)
170-177
: New.options-alert
class provides flexible alert styling.The properties are well-defined for a future notification element. Optionally, consider reusing Magento admin alert classes if you want to align with built-in admin styling.
Block/Embed.php (2)
179-185
: Ensure consistent exception handling when decrypting the API key.The try-catch handles decryption failures gracefully by setting an empty hash. Consider logging the exception or providing user feedback if needed.
193-215
: Potential security implications of storing the decrypted key in session.While this approach promotes better performance by avoiding repeated decryption, it can pose a risk if the session is compromised. Consider storing only transient hashes or using a more secure medium for the decrypted key.

build/build-package.sh (1)
3-3
: Composer Clean Command Verification
The commandcomposer run clean
is executed to clean the environment. Please verify that your Composer configuration supports this usage (e.g., that the "clean" script is properly defined) and works as expected across environments.composer.json (1)
55-55
: Simplified Packaging Script Command
Replacing the long inline packaging command with"package": "./build/build-package.sh"
greatly simplifies the Composer scripts section and delegates the packaging logic to the dedicated build script. Ensure that./build/build-package.sh
has execute permissions (e.g., viachmod +x ./build/build-package.sh
) so that it runs smoothly in all environments.etc/db_schema.xml (1)
21-21
: Appropriate schema addition for JS API key.Adding this column to store the JavaScript API key is a good addition that supports the secure mode feature. The column is appropriately defined as nullable since it would only be required when secure mode is enabled.
view/adminhtml/templates/selectwidget.phtml (2)
150-160
: Clear and informative security options section.The addition of the Security Options section with a clear explanatory notice about when the JavaScript API key is required is well structured. The password input type is appropriate for sensitive credentials.
164-174
:✅ Verification successful
Good UI feedback for user actions.
Adding success and error notifications provides important feedback to users when saving settings. This enhances user experience significantly.
Consider adding a brief timeout to automatically hide these messages after a few seconds for better UX.
🏁 Script executed:
#!/bin/bash # Check if JavaScript already handles the timeout for alert messages grep -A 10 "optionsSuccessMessage\|optionsFailureMessage" view/adminhtml/web/js/tawk-widget-select.jsLength of output: 526
UX Review: Auto-Hide Functionality Confirmed!
Great work on adding clear feedback messages for user actions. The JavaScript in
view/adminhtml/web/js/tawk-widget-select.js
already implements an auto-hide behavior (using a 3000ms delay and fade-out effect) for both success and failure messages. This means the timeout functionality is already in place, and no further changes are required.view/adminhtml/web/js/tawk-widget-select.js (5)
46-46
: Good implementation of API key value retrieval.Correctly sets the API key field value from the server response, ensuring the form is properly populated with existing configuration.
66-66
: Secure transmission of API key.Properly includes the JavaScript API key in the form submission data when setting the widget.
68-72
: Important success verification added.Added response validation before executing the callback action. This prevents sending incorrect messages back to the source when the operation fails.
98-98
: Consistent API key handling.Correctly includes the JavaScript API key in the form submission when saving visibility options, mirroring the implementation in the setWidget function.
100-106
: Enhanced error handling with user feedback.The improved response handling now provides appropriate visual feedback based on operation success or failure. The implementation correctly shows success messages and displays error messages with details when operations fail.
I see that the messages are already configured to automatically fade out after 3 seconds (
.delay(3000).fadeOut()
), which is a good user experience practice.view/frontend/templates/embed.phtml (1)
37-38
:❓ Verification inconclusive
Important security enhancement with visitor hash.
Adding the hash property to the visitor object is critical for the secure mode implementation. This allows for secure visitor recognition without exposing sensitive information.
The implementation correctly escapes the hash value using
escapeJs
to prevent XSS vulnerabilities.Let's confirm that the hash generation is implemented properly on the backend:
🏁 Script executed:
#!/bin/bash # Check how the hash is generated in the Block/Embed.php file grep -r -n "getCurrentCustomerDetails" --include="*.php" . grep -A 30 -B 5 "hash" --include="Block/Embed.php" .Length of output: 203
Security Verification for Visitor Hash Integration
The template code correctly escapes the visitor hash using
escapeJs
. However, the earlier backend check using grep ran into issues because the command was targeting a directory rather than the specific file. Please manually verify the hash generation logic inBlock/Embed.php
by re-running a corrected command such as:grep -A 30 -B 5 "hash" Block/Embed.php
This will confirm that the hash is generated as expected to securely recognize visitors.

153-156
: Appropriate error-handling.Catching exceptions around
setJsApiKey()
ensures that errors are reported gracefully.
163-185
: Secure and validated JS API Key handling.
- Returning early if
JS_API_KEY_NO_CHANGE
or empty is a good approach.- Enforcing length 40 ensures key integrity, though consider documenting or externalizing this requirement.
- Encryption with
$this->encryptor->encrypt()
is a solid practice.Block/Embed.php (8)
24-25
: Good addition of necessary classes for encryption & exception handling.These imports are essential to enable the new encryption feature and provide descriptive error messages to the user.
32-32
: Clear naming convention for new constant.Defining
TAWKTO_JS_API_KEY
as a constant enhances readability by providing a clear identifier for the key used in session storage.
83-89
: Appropriately documented encryptor property.The added property and its docblock clearly convey the new Encryptor interface’s purpose. This is good for maintaining clarity in the codebase.
97-97
: Docblock improvement for constructor parameter.Including
@param EncryptorInterface $encryptor
ensures clarity and consistency in documentation.
105-105
: Constructor signature updated to accommodate EncryptorInterface.This addition is a logical step for enabling secure decryption. It’s consistent with the new encryption feature.
113-116
: Successful assignment of encryptor dependency.Storing
$encryptor
in a protected property allows reuse across the class without cluttering the constructor.
163-164
: Docblock expanded to include 'email' and 'hash' fields.Documenting additional return values helps maintain clarity for future maintainers. Good job updating it.
188-189
: Return array includes the newly introduced hash.Providing the hashed email in the response upholds security requirements. Ensure the front-end logic properly validates and handles empty hashes.

: Thorough validation and security for JS API key.The method implements several security best practices:
- Special case handling for "no change" scenario
- Proper null handling for empty values
- Length validation (40 characters)
- Encryption of sensitive data before storage
One suggestion to consider:
- if (strlen(trim($jsApiKey)) !== 40) { + $trimmedKey = trim($jsApiKey); + if (strlen($trimmedKey) !== 40) { throw new LocalizedException(__('Invalid API key. Please provide value with 40 characters')); } - return $model->setJsApiKey($this->encryptor->encrypt($jsApiKey)); + return $model->setJsApiKey($this->encryptor->encrypt($trimmedKey));This avoids calling
trim()
twice and ensures we store the trimmed value.Block/Embed.php (1)
225-241
: Secure handling of JS API key decryption.The method properly:
- Validates input before processing
- Uses the platform's encryption service
- Provides clear error messages
One suggestion:
private function decryptJsApiKey(string $js_api_key) { if (empty($js_api_key)) { throw new LocalizedException(__('JS API key is empty')); } $key = $this->encryptor->decrypt($js_api_key); - return $key; }
The blank line before the return statement can be removed for consistency.

is appropriate for managing the secure JS API key feature. TheConfigInterface
import will be used for constant reference in the validation logic.
68-74
: Well-documented encryptor property.The property documentation follows Magento's documentation standards with proper formatting and type hints.
130-130
: Proper sanitization of API key input.The JS API key is properly sanitized using the helper method, consistent with how other parameters are handled in this controller.
152-159
: Good error handling and version tracking.The code correctly:
- Wraps the API key handling in a try-catch block
- Returns meaningful error responses
- Increments the configuration version to ensure caching consistency
This approach ensures robust error handling when dealing with API key operations.
etc/db_schema.xml (2)
8-8
: Good addition of config_version column.The
config_version
column is properly defined as an unsigned integer with a default value of 0. This is important for tracking configuration changes and will help with caching invalidation for the visitor hash implementation.
22-22
: Appropriate definition for the JS API key column.The
js_api_key
column is correctly defined as:
- Text type (appropriate for storing encrypted data)
- Nullable (since not all installations will use secure mode)
- With a clear comment describing its purpose
This definition aligns well with the new secure mode feature.
Block/Embed.php (4)
32-32
: Good use of constants for session keys.Using a class constant for the session key name follows best practices by centralizing the definition and avoiding string literals throughout the code.
83-116
: Proper dependency injection for the encryptor service.The code correctly:
- Declares the encryptor property with proper documentation
- Updates the constructor signature to accept the dependency
- Sets the property in the constructor
This follows Magento 2's dependency injection best practices.
162-185
: Good implementation of visitor hash in customer details.The method now includes the visitor hash in the returned data structure while maintaining backward compatibility with the existing interface.
188-223
: Well-implemented visitor hash generation with caching.The
getVisitorHash
method:
- Checks for an existing valid hash in the session first (optimization)
- Validates using both email and configuration version to ensure freshness
- Properly handles exceptions during key decryption
- Uses a secure hashing algorithm (HMAC-SHA256)
- Stores results in session for performance
This implementation follows security best practices for generating visitor identification hashes.

build/build-package.sh (2)
5-17
: Robustness of Copy CommandsThe series of
cp -r
commands are used to copy directories and files into the temporary packaging directory. It might be worthwhile to add checks (or rely on the aforementionedset -e
) to ensure that all source directories and files exist before attempting to copy them. This can help prevent the script from failing unexpectedly if any of these paths are missing.
19-19
: Packaging Command EnhancementsThe packaging command
(cd ./tmp && zip -9 -rq ./tawkmagento2.zip ./tawkmagento2)
is implemented efficiently using maximum compression in quiet mode. For additional robustness, consider verifying that the zip archive was created successfully. Additionally, you might want to clean up the temporary directory once the packaging is complete.Controller/Adminhtml/SaveWidget/Index.php (1)
170-194
: Thorough implementation of the JS API key setting logic.The setJsApiKey method has:
- Appropriate handling of unchanged or empty key values
- Proper validation of key length
- Key trimming before validation and encryption
- Appropriate error handling
Consider improving the error message for invalid API key - it currently doesn't tell users what's expected.
- throw new SaveWidgetException(__('Invalid API key')); + throw new SaveWidgetException(__('Invalid API key: must be exactly 40 characters long'));Block/Embed.php (1)
193-230
: Well-implemented hash generation with caching.The hash generation logic:
- Uses session caching to avoid repeated decryption operations
- Validates the session data against the current email and config version
- Checks for the presence of an encrypted key before attempting to decrypt
- Uses a secure hashing algorithm (HMAC SHA256)
- Stores the computed hash in the session for reuse
Consider adding a check to verify the decryption was successful before using the key for hashing.
$jsApiKey = $this->encryptor->decrypt($encryptedJsApiKey); + if (empty($jsApiKey)) { + return null; + } $hash = hash_hmac('sha256', $email, $jsApiKey);

Proper Shebang & Error Handling Consideration
The script begins with a proper shebang (#!/bin/sh
). Consider adding error handling options (e.g., set -e
, set -u
, and/or set -o pipefail
) immediately after the shebang to ensure the script exits on failure, which can help avoid silent failures in the build process.

: Good implementation of session caching for the visitor hash.The code correctly checks if the hash already exists in the session and validates that the email and config version match before reusing it. This is an efficient approach that prevents unnecessary recalculations.
203-205
: Proper validation before decryption.Good practice to check if the encryptedJsApiKey is empty before attempting to decrypt it, addressing a previous review comment.
221-227
: Secure implementation of visitor hash.The implementation uses hash_hmac with SHA-256, which is a secure approach for generating the visitor hash. The session storage also correctly includes the email and config version to invalidate the hash if these values change.
223-227
: Avoid storing sensitive data in session.Based on a previous review comment, consider storing only the hash in the session rather than including the email. The email could be compared directly from the customer session when needed.
