Code Review
안녕하세요. 이번 PR에서 로그인 폼의 재사용성과 상태 관리를 개선하신 점 잘 보았습니다. 신규 FormInput 컴포넌트를 도입하여 UI를 일관성 있게 관리하고, useActionState를 활용하여 React 19의 새로운 패턴을 적용하려는 노력이 돋보입니다.
전반적으로 좋은 방향의 개선이지만, 몇 가지 추가 개선점을 제안드리고자 합니다. 새로 만드신 FormInput 컴포넌트의 재사용성을 더욱 높이기 위해 ref 전달 기능을 추가하고, LoginForm에서는 useActionState의 이점을 최대한 활용하여 불필요한 상태 관리를 제거하는 방향으로 피드백을 드렸습니다.

Code Review
This PR introduces a reusable FormInput component and applies it to the login form, improving code consistency and maintainability. It also leverages useActionState for server action state management and enhances semantics by changing button to Link. A security review identified a potential medium-severity Cross-Site Scripting (XSS) vulnerability in the new FormInput.tsx component due to the use of the spread operator (...rest), which has been addressed by explicitly defining allowed props, including a style prop that aligns with the rule for using inline styles for precise values. Additionally, the useState in LoginForm for the email input seems unnecessary, as server actions handle FormData directly, suggesting uncontrolled components might be simpler. Enhancing the FormInput component to accept ref would also significantly improve its usability. Please check the specific comments for detailed feedback and recommendations.

The FormInput component currently uses the object spread operator (...rest) to pass props to the underlying <input> element. This introduces a potential medium-severity Cross-Site Scripting (XSS) vulnerability, as malicious event handlers (e.g., onmouseover, onerror) or other dangerous attributes could be injected if the props are ever derived from user-controlled input. The provided code suggestion explicitly defines the allowed props, which is crucial for mitigating this XSS risk by preventing unintended attributes from being passed. For further improvements, consider enhancing FormInputProps by extending React.InputHTMLAttributes for better type definition and implementing React.forwardRef to allow ref forwarding, which would increase the component's versatility.
const FormInput = ({
id,
type,
name,
placeholder,
autoComplete,
required = false,
className = "",
style = {},
value,
onChange
}: FormInputProps) => {
return (
<input
id={id}
type={type}
name={name}
placeholder={placeholder}
autoComplete={autoComplete}
required={required}
className={cn(INPUT_CLASSNAME, className)}
style={{ ...INPUT_STYLE, ...style }}
value={value}
onChange={onChange}
/>
);
};

- The suggested code includes a
styleprop, which allows for inline styles. This aligns with the guideline to use inline styles when precise values, such as forbox-shadoworborder, cannot be accurately represented by existing Tailwind utility classes.

서버 액션과 useActionState를 사용하는 현재 구조에서는 입력 필드를 비제어(uncontrolled) 방식으로 사용하는 것이 더 효율적이고 코드도 간결해집니다. 이메일 필드를 useState로 제어하는 것은 불필요한 리렌더링을 유발하며, 비밀번호 필드와도 일관성이 맞지 않습니다. loginAction이 FormData를 통해 값을 처리하므로, value와 onChange props를 제거하고 관련 useState도 삭제하는 것을 권장합니다.

✨ Describe tool usage guide:
Overview:
The
describetool scans the PR code changes, and generates a description for the PR - title, type, summary, walkthrough and labels. The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on a PR.When commenting, to edit configurations related to the describe tool (
pr_descriptionsection), use the following template:With a configuration file, use the following template:
Enabling\disabling automation
meaning the
describetool will run automatically on every PR.the tool will replace every marker of the form
pr_agent:marker_namein the PR description with the relevant content, wheremarker_nameis one of the following:type: the PR type.summary: the PR summary.walkthrough: the PR walkthrough.diagram: the PR sequence diagram (if enabled).Note that when markers are enabled, if the original PR description does not contain any markers, the tool will not alter the description at all.
Custom labels
The default labels of the
describetool are quite generic: [Bug fix,Tests,Enhancement,Documentation,Other].If you specify custom labels in the repo's labels page or via configuration file, you can get tailored labels for your use cases.
Examples for custom labels:
Main topic:performance- pr_agent:The main topic of this PR is performanceNew endpoint- pr_agent:A new endpoint was added in this PRSQL query- pr_agent:A new SQL query was added in this PRDockerfile changes- pr_agent:The PR contains changes in the DockerfileThe list above is eclectic, and aims to give an idea of different possibilities. Define custom labels that are relevant for your repo and use cases.
Note that Labels are not mutually exclusive, so you can add multiple label categories.
Make sure to provide proper title, and a detailed and well-phrased description for each label, so the tool will know when to suggest it.
Inline File Walkthrough 💎
For enhanced user experience, the
describetool can add file summaries directly to the "Files changed" tab in the PR page.This will enable you to quickly understand the changes in each file, while reviewing the code changes (diffs).
To enable inline file summary, set
pr_description.inline_file_summaryin the configuration file, possible values are:'table': File changes walkthrough table will be displayed on the top of the "Files changed" tab, in addition to the "Conversation" tab.true: A collapsable file comment with changes title and a changes summary for each file in the PR.false(default): File changes walkthrough will be added only to the "Conversation" tab.Utilizing extra instructions
The
describetool can be configured with extra instructions, to guide the model to a feedback tailored to the needs of your project.Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Notice that the general structure of the description is fixed, and cannot be changed. Extra instructions can change the content or style of each sub-section of the PR description.
Examples for extra instructions:
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.
