1. Overview
1.1 PR Summary
- Business value and requirements alignment: This PR introduces a new reusable component,
ImageUpload, which fulfills the design requirements and follows MUI's suggestions for uploading files. It allows users to upload images with drag-and-drop functionality, file size and format validation, and error handling. - Key components modified:
ImageUploadcomponent - Impact assessment: This component will impact the user interface and user experience, as well as the application's file handling and validation processes. It will likely be integrated across multiple parts of the application.
- System dependencies and integration impacts: The component interacts with the user's file system for drag-and-drop and file selection, the application's state for updating the image source (
src), and the application's theme for styling. It also uses thecreateToastutility for displaying error messages, which suggests an interaction with the application's notification system.
2. Detailed Technical Analysis
2.1 Code Logic Deep-Dive
Core Logic Changes
- src/Components/Inputs/ImageUpload/index.jsx - ImageUpload
- Submitted PR Code:
const handleImageChange = useCallback(
(file) => {
if (file.size > maxSize) {
createToast({
body: "File size is too large",
});
return;
}
onChange(file);
},
[maxSize, onChange]
);- Analysis:
- Current logic and potential issues: The
handleImageChangefunction validates the file size on the client-side, which could be bypassed by a malicious user. Additionally, the function does not handle other types of errors (e.g., network errors, server errors). - Edge cases and error handling: The function does not handle cases where the file is not an image or does not meet the accepted file formats. It also does not handle cases where the file is too large to be uploaded to the server.
- **Cross-component impact **: The function interacts with the
createToastutility, which suggests an interaction with the application's notification system. This could lead to unexpected behavior if the notification system is not functioning properly. - **Business logic considerations **: The function does not consider the business logic for file uploads, such as the maximum file size allowed on the server or the accepted file formats for a specific use case.
- Current logic and potential issues: The
- LlamaPReview Suggested Improvements:
const handleImageChange = useCallback(
async (file) => {
if (!(file instanceof Blob) || !file.type.startsWith("image/")) {
createToast({
body: "Invalid file format",
});
return;
}
if (file.size > maxSize) {
createToast({
body: "File size is too large",
});
return;
}
try {
const response = await fetch("/upload", {
method: "POST",
body: file,
});
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
const data = await response.json();
onChange(data.fileUrl);
} catch (error) {
createToast({
body: "Error uploading file",
});
console.error(error);
}
},
[maxSize, onChange]
);-
Improvement rationale:
- Technical benefits: The improved function handles additional edge cases, such as invalid file formats and network errors. It also implements server-side validation to ensure data integrity.
- Business value: The improved function provides a better user experience by displaying more descriptive error messages and handling network errors gracefully. It also ensures that only valid files are uploaded to the server, which improves the application's security and data integrity.
- Risk assessment: The improved function reduces the risk of data corruption and security vulnerabilities by implementing server-side validation and handling additional error cases. It also reduces the risk of user confusion or frustration by displaying more descriptive error messages and handling network errors gracefully.

- Current logic and potential issues: The input element does not have an
idattribute, which makes it inaccessible to screen readers and keyboard navigation. Additionally, the input element does not have aaria-labelattribute, which makes it difficult for users with visual impairments to understand its purpose. - Edge cases and error handling: The input element does not handle cases where the user selects multiple files or drags and drops multiple files. It also does not handle cases where the user cancels the file selection or drag-and-drop operation.
- **Cross-component impact **: The input element interacts with the
handleImageChangefunction, which suggests an interaction with the application's file handling system. This could lead to unexpected behavior if the file handling system is not functioning properly. - **Business logic considerations **: The input element does not consider the business logic for file selection, such as the maximum number of files that can be selected or the accepted file formats for a specific use case.

2.2 Implementation Quality
- Code organization and structure: The component is well-organized and follows a clear structure, with separate sections for imports, component definition, and export. It also uses a functional component with hooks for state management and memoization.
- Design patterns usage: The component uses the
useCallbackhook for memoization and theuseThemehook for applying theme-specific styles. It also uses thePropTypeslibrary for type checking. - Error handling approach: The component uses the
createToastutility for displaying error messages, but it does not handle other types of errors (e.g., network errors, server errors). Robust error handling should be implemented to ensure a smooth user experience. - Resource management: The component uses the
useCallbackhook for memoization, which helps optimize performance by avoiding unnecessary re-renders. It also uses theuseThemehook for applying theme-specific styles, which helps ensure consistent styling across the application.
3. Critical Findings
3.1 Potential Issues
- 🔴 Critical Issues
- File validation: The component only validates file size on the client-side, which could be bypassed by a malicious user. Server-side validation should also be implemented to ensure data integrity.
- Error handling: The component does not handle other types of errors (e.g., network errors, server errors). Robust error handling should be implemented to ensure a smooth user experience.
- 🟡 Warnings
- File format validation: The component only validates a limited set of image formats. Additional formats may need to be supported in the future, or the component may need to be extended to support non-image files.
- File upload limits: The component has a maximum file size limit of 3MB, which may not be sufficient for all use cases. The limit should be configurable and documented to ensure system stability.
- File upload progress: The component does not provide any feedback to the user during file uploads, which could lead to user confusion or frustration. File upload progress should be displayed to improve the user experience.
- Cross-site scripting (XSS): The component displays user-uploaded images without any sanitization, which could make the application vulnerable to XSS attacks. Image sanitization should be implemented to ensure security.
- Cross-site request forgery (CSRF): The component does not implement any CSRF protection, which could make the application vulnerable to CSRF attacks. CSRF protection should be implemented to ensure security.
3.2 Code Quality Concerns
- Maintainability aspects: The component is well-organized and follows a clear structure, with separate sections for imports, component definition, and export. It also uses a functional component with hooks for state management and memoization.
- Readability issues: The component is well-documented with comments and uses clear variable names, making it easy to understand and maintain.
- Performance bottlenecks: The component uses the
useCallbackhook for memoization, which helps optimize performance by avoiding unnecessary re-renders. It also uses theuseThemehook for applying theme-specific styles, which helps ensure consistent styling across the application.
4. Security Assessment
- Authentication/Authorization impacts: The component does not have any authentication or authorization requirements, as it is a file upload component.
- Data handling concerns: The component handles user-uploaded files, which could contain sensitive data. Proper data handling and sanitization should be implemented to ensure security.
- Input validation: The component validates file size and format on the client-side, but it does not validate other file properties (e.g., dimensions, aspect ratio). Robust input validation should be implemented to ensure data integrity.
- Security best practices: The component uses the
createToastutility for displaying error messages, but it does not handle other types of errors (e.g., network errors, server errors). Robust error handling should be implemented to ensure a smooth user experience and prevent information disclosure. - Potential security risks: The component displays user-uploaded images without any sanitization, which could make the application vulnerable to XSS attacks. Image sanitization should be implemented to ensure security.
- Mitigation strategies: Image sanitization should be implemented to prevent XSS attacks. Robust input validation and error handling should be implemented to ensure data integrity and prevent information disclosure.
- Security testing requirements: The component should be tested for security vulnerabilities, such as XSS attacks and CSRF attacks. It should also be tested for proper data handling and sanitization.
5. Testing Strategy
5.1 Test Coverage
- Unit test analysis: Unit tests should be written to validate the component's behavior under various scenarios, including edge cases and error conditions. They should also test the component's interaction with other parts of the application, such as the notification system and the file handling system.
- Integration test requirements: Integration tests should be written to validate the component's interaction with other parts of the application, such as the notification system and the file handling system. They should also test the component's behavior under various network conditions, such as slow or unstable connections.
- Edge cases coverage: Edge cases should be tested, such as invalid file formats, file sizes that exceed the maximum limit, and network errors. They should also test the component's behavior when the user cancels the file selection or drag-and-drop operation.
5.2 Test Recommendations
Suggested Test Cases
// Test case for file size validation
it("should not accept files larger than the maximum size", () => {
const file = new Blob(["Hello, World!"], { type: "text/plain" });
file.size = 4 * 1024 * 1024; // 4MB
const onChange = jest.fn();
const { getByTestId } = render(<ImageUpload onChange={onChange} maxSize={3 * 1024 * 1024} />); // 3MB
const input = getByTestId("image-upload");
userEvent.upload(input, file);
expect(onChange).not.toHaveBeenCalled();
});
// Test case for file format validation
it("should not accept files with invalid formats", () => {
const file = new Blob(["Hello, World!"], { type: "text/plain" });
const onChange = jest.fn();
const { getByTestId } = render(<ImageUpload onChange={onChange} accept={["jpg", "jpeg", "png"]} />);
const input = getByTestId("image-upload");
userEvent.upload(input, file);
expect(onChange).not.toHaveBeenCalled();
});
// Test case for network errors
it("should handle network errors gracefully", async () => {
const file = new Blob(["Hello, World!"], { type: "image/jpeg" });
const onChange = jest.fn();
const { getByTestId } = render(<ImageUpload onChange={onChange} />);
const input = getByTestId("image-upload");
userEvent.upload(input, file);
await waitFor(() => expect(onChange).toHaveBeenCalled());
const mockFetch = jest.fn().mockRejectedValue(new Error("Network error"));
window.fetch = mockFetch;
userEvent.upload(input, file);
await waitFor(() => expect(mockFetch).toHaveBeenCalledTimes(2));
});- Coverage improvements: The component should be tested for 100% code coverage, including edge cases and error conditions. It should also be tested for proper data handling and sanitization.
- Performance testing needs: The component should be tested for performance under various network conditions, such as slow or unstable connections. It should also be tested for proper resource management, such as memory usage and garbage collection.
6. Documentation & Maintenance

src/Components/Inputs/ImageUpload/index.jsx (3)
13-26: Yo dawg, let's beef up that documentation!The JSDoc is pretty solid, but it's missing some key validation deets that would help other devs not lose their spaghetti:
- Accepted file formats validation behaviour
- Error object structure
- Return value when validation fails
31-33: Mom's spaghetti alert: hardcoded values!The maxSize and accept props have hardcoded default values. Consider:
- Moving maxSize to environment config for easier updates
- Using a more specific PropType for accept (arrayOf(string))
- maxSize = 3 * 1024 * 1024, + maxSize = process.env.REACT_APP_MAX_UPLOAD_SIZE || 3 * 1024 * 1024,
51-63: Weak knees in the UX department!The image preview could use some improvements:
- Add loading state
- Handle broken image scenarios
- Consider adding image optimization
<Image alt="company logo" maxWidth="250px" maxHeight="250px" src={src} + loading="lazy" + onError={(e) => { + createToast({ body: "Failed to load image" }); + e.target.src = '/fallback-image.png'; + }} sx={{ ...roundStyle }} />

// Components -import { Button, Box, Stack, Typography } from "@mui/material"; -import CloudUploadIcon from "@mui/icons-material/CloudUpload"; -import Image from "../../../Components/Image"; +import CloudUploadIcon from "@mui/icons-material/CloudUpload"; +import { useTheme } from "@emotion/react"; +import { Box, Button, Stack, Typography } from "@mui/material"; +import Image from "../../../Components/Image"; // Utils -import PropTypes from "prop-types"; -import { createToast } from "../../../Utils/toastUtils"; -import { formatBytes } from "../../../Utils/fileUtils"; -import { useCallback } from "react"; -import { useTheme } from "@emotion/react"; +import { useCallback } from "react"; +import PropTypes from "prop-types"; +import { formatBytes } from "../../../Utils/fileUtils"; +import { createToast } from "../../../Utils/toastUtils";
54-60: Mom's spaghetti on the alt text!The Image component's alt text is too generic:
- Make it more descriptive
- Consider making it a prop
<Image - alt="company logo" + alt={alt || "Uploaded image preview"} maxWidth="250px" maxHeight="250px" src={src} sx={{ ...roundStyle }} />And add it to PropTypes:
ImageUpload.propTypes = { + alt: PropTypes.string, previewIsRound: PropTypes.bool, // ... rest of the props };

🛠️ Refactor suggestion
Drop it like it's hot, but safely!
The drag and drop handlers need some defensive programming:
- Add error handling for failed drops
- Validate file count (only one file allowed)
onDrop={(e) => {
e.preventDefault();
- handleImageChange(e?.dataTransfer?.files?.[0]);
+ try {
+ const files = e?.dataTransfer?.files;
+ if (!files || files.length === 0) {
+ createToast({ body: "No file was dropped" });
+ return;
+ }
+ if (files.length > 1) {
+ createToast({ body: "Please drop only one file" });
+ return;
+ }
+ handleImageChange(files[0]);
+ } catch (error) {
+ createToast({ body: "Failed to process dropped file" });
+ }

I think it makes sense to just use the Image component, no need to build a new one I don't think? The original ImageUpload component doesn't work reliably, sometimes the preview image is loaded, sometimes it isn't. I don't know why and I don't think it's worth the effort trying to find out 😂 |
That makes sense. Think we can proceed with this. I can help with refining it/refactor the current code. Let me know how to proceed. |

This is a propsoal for an image-upload component.
I've tried to keep it as simple as possible while fulfiling the design requirements and following MUI's suggestions for uploading files.
Please leave your thoughts and we can see if this is a good approach.
