Code Quality Score

75/100

Summary

The code is functional but has areas for improvement in error handling, type safety, and performance.

Issues Found

Detailed findings

4 issues

Lack of Error Handling

high

Line 2

The fetch call does not handle network errors or server responses that indicate failure (like 404 or 500 status codes). This can lead to unhandled promise rejections and poor user experience.

Suggested fix: Add error handling for the fetch request, checking the response status before proceeding with json parsing.

Use of 'any' Type

medium

Line 6

The use of 'any' for the project type reduces type safety and can lead to runtime errors. TypeScript should aim for strong typing.

Suggested fix: Define an appropriate interface for the project type instead of using 'any'.

Inefficient String Concatenation

low

Line 1

Concatenating strings using '+' is less efficient than using template literals.

Suggested fix: Change to use template literals: `fetch(`/api/users/${userId}`)`.

Redundant Boolean Comparison

low

Line 4

The comparison 'user.isAdmin == true' is redundant. It can be simplified to 'user.isAdmin'.

Suggested fix: Change the condition to 'if (user.isAdmin)' for cleaner code.

Improved Code

Suggested rewrite

export async function getUserProfile(userId: string) {
  try {
    const response = await fetch(`/api/users/${userId}`);
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    const user = await response.json();

    if (user.isAdmin) {
      console.log('admin user');
    }

    return {
      name: user.name,
      projects: user.projects.map((project: Project) => project.title),
    };
  } catch (error) {
    console.error('Error fetching user profile:', error);
    throw error; // Rethrow the error to notify the caller
  }
}
