The plan to solve the bug involves defining and exporting the getIncomelist function in the utils/dbConfig.jsx file and ensuring that it is correctly imported and used in the IncomeList.jsx component. This approach addresses the ReferenceError by making sure the function is available where it is needed.
What is causing this bug?
The bug is caused by the getIncomelist function not being defined or imported in the IncomeList.jsx file. This results in a ReferenceError when the function is called within the CreateIncomes component. The root cause is the absence of the getIncomelist function definition in the utils/dbConfig.jsx file and its subsequent import in the IncomeList.jsx file.
Code
Step 1: Define and Export getIncomelist in utils/dbConfig.jsx
Add the following code to utils/dbConfig.jsx to define and export the getIncomelist function:
// Existing imports
import { neon } from "@neondatabase/serverless";
import { drizzle } from "drizzle-orm/neon-http";
import * as schema from "./schema";
// Database connection setup
const sql = neon(
"postgresql://finan-smart_owner:uk3aed9QZotj@ep-wispy-breeze-a5iadk8t.us-east-2.aws.neon.tech/finan-smart?sslmode=require"
);
export const db = drizzle(sql, { schema });
// New function to fetch the list of incomes
export async function getIncomelist() {
try {
const incomes = await db.select().from(schema.incomes).execute();
return incomes;
} catch (error) {
console.error("Error fetching income list:", error);
throw error;
}
}
Step 2: Import and Use getIncomelist in IncomeList.jsx
Update the IncomeList.jsx file to import and use the getIncomelist function:
import React, { useState, useEffect } from 'react';
import { useUser } from 'some-auth-library'; // Adjust the import based on your auth library
import { getIncomelist } from '../../../utils/dbConfig'; // Adjust the path based on your project structure
import CreateIncomes from './CreateIncomes';
import IncomeItem from './IncomeItem';
function IncomeList() {
const [incomelist, setIncomelist] = useState([]);
const { user } = useUser();
useEffect(() => {
if (user) {
fetchIncomelist();
}
}, [user]);
const fetchIncomelist = async () => {
try {
const result = await getIncomelist();
setIncomelist(result);
} catch (error) {
console.error("Error fetching income list:", error);
}
};
return (
<div className="mt-7">
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-5">
<CreateIncomes refreshData={fetchIncomelist} />
{incomelist.length > 0
? incomelist.map((budget, index) => (
<IncomeItem 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 IncomeList;
How to replicate the bug
Ensure the getIncomelist function is not defined or imported in the IncomeList.jsx file.
Run the application and navigate to the dashboard incomes page.
Observe the Unhandled Runtime Error: ReferenceError: getIncomelist is not defined in the console.
Conclusion
By defining and exporting the getIncomelist function in the utils/dbConfig.jsx file and correctly importing and using it in the IncomeList.jsx file, we can resolve the ReferenceError and ensure the application functions as expected. This solution ensures that the getIncomelist function is available where it is needed, allowing the CreateIncomes component to refresh the income list without errors.

# Analysis Report
## File: `utils/dbConfig.jsx`
### Current Content
The file currently contains the following code:
```javascript
import { neon } from "@neondatabase/serverless";
import { drizzle } from "drizzle-orm/neon-http";
import * as schema from "./schema";
const sql = neon(
"postgresql://finan-smart_owner:uk3aed9QZotj@ep-wispy-breeze-a5iadk8t.us-east-2.aws.neon.tech/finan-smart?sslmode=require"
);
export const db = drizzle(sql, { schema });
```
### Observations
1. **Database Configuration**: The file sets up a connection to a PostgreSQL database using the `neon` and `drizzle-orm` libraries.
2. **Schema Import**: The schema is imported from a local module named `schema`.
3. **Export**: The configured database instance (`db`) is exported for use in other parts of the application.
### Missing Functionality
The file does not define the `getIncomelist` function, which is necessary to fetch the list of incomes from the database. This function needs to be defined and exported so it can be used in `IncomeList.jsx`.
### Plan to Address the Issue
1. **Define `getIncomelist` Function**: Create a function named `getIncomelist` that queries the database for the list of incomes.
2. **Export the Function**: Ensure that the `getIncomelist` function is exported so it can be imported in `IncomeList.jsx`.
### Proposed Code Changes
Add the following code to define and export the `getIncomelist` function:
```javascript
// Existing imports
import { neon } from "@neondatabase/serverless";
import { drizzle } from "drizzle-orm/neon-http";
import * as schema from "./schema";
// Database connection setup
const sql = neon(
"postgresql://finan-smart_owner:uk3aed9QZotj@ep-wispy-breeze-a5iadk8t.us-east-2.aws.neon.tech/finan-smart?sslmode=require"
);
export const db = drizzle(sql, { schema });
// New function to fetch the list of incomes
export async function getIncomelist() {
try {
const incomes = await db.select().from(schema.incomes).execute();
return incomes;
} catch (error) {
console.error("Error fetching income list:", error);
throw error;
}
}
```
### Explanation
- **Function Definition**: The `getIncomelist` function uses the `db` instance to query the `incomes` table defined in the schema.
- **Error Handling**: The function includes basic error handling to log and rethrow any errors that occur during the database query.
- **Export**: The function is exported so it can be imported and used in `IncomeList.jsx`.
### Conclusion
By defining and exporting the `getIncomelist` function in `utils/dbConfig.jsx`, the `IncomeList.jsx` component will be able to call this function to fetch and display the list of incomes, resolving the `ReferenceError` mentioned in the issue.

# Bug Analysis Report
## File: `app/(routes)/dashboard/incomes/_components/IncomeList.jsx`
### Issue Description
The user reported an unhandled runtime error with the following details:
```
Unhandled Runtime Error
ReferenceError: getIncomelist is not defined
Source
app\(routes)\dashboard\incomes\_components\IncomeList.jsx (46:43) @ getIncomelist
44 |
<
```
### Analysis
The error indicates that the function `getIncomelist` is not defined at the point where it is being used as a callback in the `CreateIncomes` component.
### Source Code Review
Upon reviewing the source code, the `getIncomelist` function is defined within the `IncomeList` component. However, it seems that the function is defined after it is being used in the `CreateIncomes` component. This could potentially lead to a hoisting issue where the function is not recognized at the point of its usage.
### Relevant Code Snippet
```javascript
function IncomeList() {
const [incomelist, setIncomelist] = useState([]);
const { user } = useUser();
useEffect(() => {
user && getIncomelist();
}, [user]);
const getIncomelist = async () => {
const result = await db
.select({
...getTableColumns(Incomes),
totalSpend: sql`sum(${Expenses.amount})`.mapWith(Number),
totalItem: sql`count(${Expenses.id})`.mapWith(Number),
})
.from(Incomes)
.leftJoin(Expenses, eq(Incomes.id, Expenses.budgetId))
.where(eq(Incomes.createdBy, user?.primaryEmailAddress?.emailAddress))
.groupBy(Incomes.id)
.orderBy(desc(Incomes.id));
setIncomelist(result);
};
return (
);
}
```
### Potential Cause
The `getIncomelist` function is defined after it is being used in the `CreateIncomes` component. This could lead to a situation where the function is not recognized at the point of its usage.
### Solution
To resolve this issue, ensure that the `getIncomelist` function is defined before it is used in the `CreateIncomes` component. This can be achieved by moving the function definition above its usage.
### Updated Code
```javascript
function IncomeList() {
const [incomelist, setIncomelist] = useState([]);
const { user } = useUser();
const getIncomelist = async () => {
const result = await db
.select({
...getTableColumns(Incomes),
totalSpend: sql`sum(${Expenses.amount})`.mapWith(Number),
totalItem: sql`count(${Expenses.id})`.mapWith(Number),
})
.from(Incomes)
.leftJoin(Expenses, eq(Incomes.id, Expenses.budgetId))
.where(eq(Incomes.createdBy, user?.primaryEmailAddress?.emailAddress))
.groupBy(Incomes.id)
.orderBy(desc(Incomes.id));
setIncomelist(result);
};
useEffect(() => {
user && getIncomelist();
}, [user]);
return (
);
}
```
### Conclusion
The `getIncomelist` function should be defined before it is used in the `CreateIncomes` component to avoid the `ReferenceError`. The updated code ensures that the function is defined and available at the point of its usage.
