Potential solution

The plan to solve the bug involves identifying and removing the redundant definition of the BudgetList component in the BudgetList.jsx file. The error message indicates that the BudgetList component is defined multiple times, which is causing a naming conflict and preventing the project from compiling.

What is causing this bug?

The bug is caused by the presence of two definitions of the BudgetList function within the same file (BudgetList.jsx). This results in a naming conflict, as JavaScript does not allow multiple functions with the same name in the same scope. The error message specifically points out that the BudgetList component is defined twice, once at line 10 and again at line 27.

Code

To resolve the issue, we need to remove the redundant definition of the BudgetList function. Here is the updated source code with the second BudgetList definition removed:

"use client"
import React, { useEffect, useState } from 'react'
import CreateBudget from './CreateBudget'
import { db } from '@/utils/dbConfig'
import { desc, eq, getTableColumns, sql } from 'drizzle-orm'
import { Budgets, Expenses } from '@/utils/schema'
import { useUser } from '@clerk/nextjs'
import BudgetItem from './BudgetItem'

function BudgetList() {
  const [budgetList, setBudgetList] = useState([]);
  const { user } = useUser();
  useEffect(() => {
    user && getBudgetList();
  }, [user]);

  /**
   * used to get budget List
   */
  const getBudgetList = async () => {
    const result = await db.select({
      ...getTableColumns(Budgets),
      totalSpend: sql `sum(${Expenses.amount})`.mapWith(Number),
      totalItem: sql `count(${Expenses.id})`.mapWith(Number)
    }).from(Budgets)
    .leftJoin(Expenses, eq(Budgets.id, Expenses.budgetId))
    .where(eq(Budgets.createdBy, user?.primaryEmailAddress?.emailAddress))
    .groupBy(Budgets.id)
    .orderBy(desc(Budgets.id));

    setBudgetList(result);
  }

  return (
    <div className='mt-7'>
      <div className='grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-5'>
        <CreateBudget refreshData={() => getBudgetList()} />
        {budgetList?.length > 0 ? budgetList.map((budget, index) => (
          <BudgetItem budget={budget} key={index} />
        )) : [1, 2, 3, 4, 5].map((item, index) => (
          <div key={index} className='w-full bg-slate-200 rounded-lg h-[150px] animate-pulse'></div>
        ))}
      </div>
    </div>
  );
}

export default BudgetList

How to replicate the bug

To replicate the bug, follow these steps:

1. Ensure you have the Next.js project set up and running.
2. Navigate to the file ./app/(routes)/dashboard/budgets/_components/BudgetList.jsx.
3. Add a second definition of the BudgetList function within the same file.
4. Attempt to compile the project.
5. You should see a build error indicating that the BudgetList component is defined multiple times.

By following these steps, you will encounter the same build error that was reported in the ticket.

Conclusion

The build error was caused by the multiple definitions of the BudgetList function in the same file. Removing the redundant definition resolves the conflict and should allow the project to compile successfully. This solution ensures that the BudgetList component is defined only once, eliminating the naming conflict and fixing the build error.

Analysis Report

Issue Description

The user is experiencing a build error in their Next.js project. The error message indicates that the BudgetList component is defined multiple times in the file ./app/(routes)/dashboard/budgets/_components/BudgetList.jsx.

Source of the Issue

The error message points out that the BudgetList component is defined twice in the file:

1. The first definition starts at line 10.
2. The second definition starts at line 27.

Source Code

Here is the relevant part of the source code:

"use client"
import React, { useEffect, useState } from 'react'
import CreateBudget from './CreateBudget'
import { db } from '@/utils/dbConfig'
import { desc, eq, getTableColumns, sql } from 'drizzle-orm'
import { Budgets, Expenses } from '@/utils/schema'
import { useUser } from '@clerk/nextjs'
import BudgetItem from './BudgetItem'

function BudgetList() {
  const [budgetList, setBudgetList] = useState([]);
  const { user } = useUser();
  useEffect(() => {
    user && getBudgetList();
  }, [user]);

  /**
   * used to get budget List
   */
  const getBudgetList = async () => {
    const result = await db.select({
      ...getTableColumns(Budgets),
      totalSpend: sql `sum(${Expenses.amount})`.mapWith(Number),
      totalItem: sql `count(${Expenses.id})`.mapWith(Number)
    }).from(Budgets)
    .leftJoin(Expenses, eq(Budgets.id, Expenses.budgetId))
    .where(eq(Budgets.createdBy, user?.primaryEmailAddress?.emailAddress))
    .groupBy(Budgets.id)
    .orderBy(desc(Budgets.id));

    setBudgetList(result);
  }

  return (
    <div className='mt-7'>
      <div className='grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-5'>
        <CreateBudget refreshData={() => getBudgetList()} />
        {budgetList?.length > 0 ? budgetList.map((budget, index) => (
          <BudgetItem budget={budget} key={index} />
        )) : [1, 2, 3, 4, 5].map((item, index) => (
          <div key={index} className='w-full bg-slate-200 rounded-lg h-[150px] animate-pulse'></div>
        ))}
      </div>
    </div>
  );
}

export default BudgetList

Cause of the Bug

The file contains two definitions of the BudgetList function. This is causing a naming conflict, leading to the build error.

Solution

To resolve this issue, you need to remove or rename one of the BudgetList function definitions. Since the second definition (starting at line 27) is not shown in the provided code snippet, it is safe to assume that the first definition is the intended one. Therefore, you should remove the second definition.

Updated Source Code

Here is the updated source code with the second BudgetList definition removed:

"use client"
import React, { useEffect, useState } from 'react'
import CreateBudget from './CreateBudget'
import { db } from '@/utils/dbConfig'
import { desc, eq, getTableColumns, sql } from 'drizzle-orm'
import { Budgets, Expenses } from '@/utils/schema'
import { useUser } from '@clerk/nextjs'
import BudgetItem from './BudgetItem'

function BudgetList() {
  const [budgetList, setBudgetList] = useState([]);
  const { user } = useUser();
  useEffect(() => {
    user && getBudgetList();
  }, [user]);

  /**
   * used to get budget List
   */
  const getBudgetList = async () => {
    const result = await db.select({
      ...getTableColumns(Budgets),
      totalSpend: sql `sum(${Expenses.amount})`.mapWith(Number),
      totalItem: sql `count(${Expenses.id})`.mapWith(Number)
    }).from(Budgets)
    .leftJoin(Expenses, eq(Budgets.id, Expenses.budgetId))
    .where(eq(Budgets.createdBy, user?.primaryEmailAddress?.emailAddress))
    .groupBy(Budgets.id)
    .orderBy(desc(Budgets.id));

    setBudgetList(result);
  }

  return (
    <div className='mt-7'>
      <div className='grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-5'>
        <CreateBudget refreshData={() => getBudgetList()} />
        {budgetList?.length > 0 ? budgetList.map((budget, index) => (
          <BudgetItem budget={budget} key={index} />
        )) : [1, 2, 3, 4, 5].map((item, index) => (
          <div key={index} className='w-full bg-slate-200 rounded-lg h-[150px] animate-pulse'></div>
        ))}
      </div>
    </div>
  );
}

export default BudgetList

Conclusion

The build error was caused by the multiple definitions of the BudgetList function in the same file. Removing the redundant definition resolves the conflict and should allow the project to compile successfully.
