Code Quality Score

75/100

Summary

Code is functional but lacks type safety and error handling.

Issues Found

Detailed findings

4 issues

Lack of Type Definitions

medium

Line 3-5

The 'user' and 'project' types are not defined, which can lead to potential runtime errors and reduces code clarity.

Suggested fix: Define a 'User' and 'Project' interface to provide proper type definitions for the fetched data.

Error Handling for Fetch

high

Line 2

There is no error handling for the fetch request, which can lead to uncaught errors if the network request fails or if the response is not successful.

Suggested fix: Add try-catch block around the fetch call and check for response.ok before processing the response.

Inefficient Boolean Check

low

Line 5

The `user.isAdmin == true` check can be simplified since 'isAdmin' is already a boolean.

Suggested fix: Change the condition to simply 'if (user.isAdmin)'.

Potential Null Reference

medium

Line 8

If the fetch call fails or the user data does not include expected fields, this could lead to runtime errors when accessing properties.

Suggested fix: Include checks to ensure 'user' and its properties are defined before accessing them.

Improved Code

Suggested rewrite

export interface User {
  name: string;
  isAdmin: boolean;
  projects: Project[];
}

export interface Project {
  title: string;
}

export async function getUserProfile(userId: string) {
  try {
    const response = await fetch("/api/users/" + userId);
    if (!response.ok) {
      throw new Error(`Error fetching user: ${response.statusText}`);
    }
    const user: User = await response.json();

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

    return {
      name: user.name,
      projects: user.projects ? user.projects.map((project: Project) => project.title) : [],
    };
  } catch (error) {
    console.error(error);
    return null;  // Or consider throwing an error/rejecting promise
  }
}
