Efficiently Batch Writing Documents in Firestore with Next.js
Tags: firebase, nextjs, api, javascript
Published: 2024-05-28 10:00:48


In the fast-evolving world of web development, optimizing data handling processes is crucial for performance and scalability. Today, we're discussing a powerful approach to managing data with Firestore within a Next.js environment. At [itselftools.com](https://itselftools.com), we've developed over 30 projects using Next.js and Firebase, and have gained valuable insights that we are eager to share with you.

## Understanding the Code

Here is a brief explanation of what the provided Node.js code does when integrated into a Next.js API route:

```javascript
// 7. API Route to batch write multiple documents in Firestore
const { db } = require('../../firebase');

export default async function handler(req, res) {
  if (req.method === 'POST') {
    const users = req.body;
    try {
      const batch = db.batch();
      users.forEach(user => {
        const docRef = db.collection('users').doc();
        batch.set(docRef, user);
      });
      await batch.commit();
      res.status(200).json({ message: 'Batch write successful' });
    } catch (e) {
      res.status(400).json({ message: 'Batch write failed' });
    }
  } else {
    res.setHeader('Allow', ['POST']);
    res.status(405).end(`Method ${req.method} Not Allowed`);
  }
}
```

### Step-by-Step Breakdown

1. **Check Request Method**: The server checks if the incoming request is a POST. If not, it rejects the request with a 405 Method Not Allowed status.
2. **Create a Batch Object**: A batch object is created using `db.batch()`, allowing multiple writes to be grouped into a single transaction.
3. **Document References and Write Operations**: For each user in the request body, a new document reference in the 'users' collection is created. Each user's data is then written to their respective document through the `batch.set()` method.
4. **Commit the Batch**: The batch of writes is committed asynchronously using `await batch.commit()`. If successful, the operation returns a status of 200, indicating a successful batch write.
5. **Error Handling**: In the event of an exception (e.g., a failed write operation), the server responds with a status of 400 and an explanatory message.

## Why Use Batch Writing?

Batch writing is an efficient way to write multiple documents to Firestore simultaneously. This method reduces network requests, minimizes write operation overhead, and significantly enhances performance, especially when dealing with large sets of data.

## Conclusion

Leveraging batch writes in Firestore within your Next.js applications can lead to more efficient, reliable, and scalable data handling.

Solving the Radix Integration Issue in Next.js
Tags: nextjs, radix, webdev, buildinpublic
Published: 2024-05-28 09:56:28

I am Leo Hoang. Currently, I am working on my next startup project: Workodoro. While working with the Workodoro application, I encountered an issue integrating Radix into Next.js.

From version 13.0 to 14.1, Next.js has an issue with the import order of CSS files in app/**/layout.tsx. This can result in Radix Themes overwriting your custom styles, even when the import statements are correctly structured:

```javascript
import '@radix-ui/themes/styles.css';
import './my-styles.css';
```

This problem can occur sporadically, affecting either development or production environments, leading to inconsistencies. Fortunately, there are effective solutions to ensure your styles are applied as intended.

### Solution

**Merging CSS Files with postcss-import**

The most reliable method is to merge all CSS into a single file using the postcss-import plugin. This approach ensures a consistent import order by consolidating all your styles into one unified file.

#### Step-by-Step Guide:

**1. Install postcss-import:** First, install the postcss-import plugin:

```bash
npm install postcss-import
```

**2. Configure postcss.config.js:** Add postcss-import to your postcss.config.js file:

```javascript
module.exports = {
  plugins: {
    "postcss-import": {},
    tailwindcss: {},
    autoprefixer: {},
  },
};
```

**3. Update Your CSS File:** Import Tailwind's base styles first, followed by Radix Themes, and then your components and utilities:

```css
@import "tailwindcss/base";
@import "@radix-ui/themes/styles.css";

@tailwind components;
@tailwind utilities;
```

This setup ensures that Tailwind’s base styles load first, followed by Radix Themes, and then your custom components and utilities, maintaining a proper and predictable order.

### Conclusion

These brief notes hope to help someone facing a similar issue save time.

HFDP(11) - Proxy Pattern
Published: 2024-05-28 09:37:39

Proxy manages and controls access. Proxy is a stand in for a real object. Proxy pattern has a lot of variations. 

For example, if we want to call a method of an object living remotely in another JVM, we need to make use of the Remote Proxy. In java, we could achieve this by using `rmi` technology. Basically, the client calls a stub that implements the same Remote interface as the real subject. The stub then forwards the request to the skeleton living in the JVM, which then calls the real subject and forwards back returned value. Through the time, the client thinks it is accessing the real subject, which it is not doing this directly. 


![Remote Proxy](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/tn9k3g47fiykbgu11lcg.png)

Another well-known example is the Virtual Proxy. It is used for wrapping an expensive object like an image fetched from a network. Let's say you want to display an image on screen. Instead of fetching the image and manages the waiting yourself, you could delegate the task to a virtual proxy. It will fire a thread to fetch the image, and renders waiting texts while waiting. In this manner, you reduced the coupling in code. 


![Virtual Proxy](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/oi9uwtxohfcm59muk5xb.png)


We may also need to manage access, which brings the Protection Proxy. It wraps an object and decides if the client could access certain methods of it. In Java it is implemented via reflection. e.g. 

```java
Person getOwnerProxy(Person, person) {
  return (Person) Proxy.newProxyInstance(
    person.getClass().getClassLoader(),
    person.getClass().getInterfaces(),
    new OwnerIncovationHandler(person));
}
```

where `OwnerIncovationHandler` implements `InvocationHandler`. Its method signature is `Object invoke(Object proxy, Method method, Object[] args)`. 

We've seen a number of patterns that serve as wrapper. They look similar but serves different purposes: 
- Decorator Pattern: wrap an object add behaviors
- Facade Pattern: wrap possible many objects and simplify interfaces
- Adapter Pattern: wraps an object and implements another interface
- Proxy Pattern: wraps an object and controls access. 

Proxy pattern has many variations: 
- Firewall Proxy (control access to network recourses) -> e.g. corporate firewall system. 
- Smart Reference Proxy (provide additional actions when a subject is referenced e.g. count)
- Caching Proxy (temp store expensive resources) -> web server proxies and content management and publishing systems. 
- Synchronization Proxy (provides safe access to a subject from multiple threads) 
- Complexity Hiding Proxy (pretty much like Facade) 
- Copy-on-Write Proxy (lazy copying, variant of Virtual Proxy)

Understanding Dyslexia in Children; Indicators, Diagnosis and Effective Support
Published: 2024-05-28 09:44:07

Parents often misconstrue dyslexia as an excuse crafted by children to evade studying. However, the reality is far deeper than being a reading difficulty. Dyslexia is a condition that impacts how the brain processes written and spoken language. Despite struggles with reading, writing and comprehension skills, individuals with dyslexia often exhibit strengths in problem solving and creativity.

Detecting signs of dyslexia in children plays a role, in nurturing their growth and helping them unleash their potential. Here are some common signs to be aware of;

- Struggling to learn words and sounds
- development of language skills
- Difficulties, with reading, spelling and writing fluently
- Trouble distinguishing left from right
- Issues with remembering sequences and following instructions accurately
- Skimming over or misinterpreting words

The causes of dyslexia can vary from person to person. While some individuals may exhibit one symptom others may display two or three. Dyslexia is a condition influenced by factors such as genetics, premature birth and exposure to substances during pregnancy.

Despite the challenges that dyslexia poses it does not determine a child's potential. With assistance and support children with dyslexia can excel academically and in areas of their lives. To learn more about this condition and available treatment options check out the blog linked below.

### Case Study: Bug Fixing

In this case study, we'll identify common challenges in using conditional execution and iteration. You'll learn practical solutions to optimize performance and maintain code readability, ensuring your programs run efficiently and are easy to understand.


**Problem**: Debug a program that calculates factorial numbers but encounters errors with negative inputs.

**Solution**: 
1. Implement error handling using conditional checks.
2. Ensure the program handles invalid inputs gracefully.

**Python Code** with Comments:
```python
# Function to calculate factorial of a number
def factorial(n):
    # Handle negative numbers
    if n < 0:
        return "Error! Factorial is not defined for negative numbers."
    # Base case for factorial
    elif n == 0 or n == 1:
        return 1
    # Calculate factorial for positive integers
    else:
        result = 1
        for i in range(2, n + 1):
            result *= i
        return result

# Main program to input a number, calculate factorial, and display result
def main():
    number = int(input("Enter a number to calculate its factorial: "))
    print("Factorial:", factorial(number))

if __name__ == "__main__":
    main()
```
---

In the bug-fixing case study, we encountered a common challenge in programming—handling invalid inputs. By implementing error handling techniques, we addressed this challenge and ensured the robustness of our program. Understanding and addressing common challenges are essential for developing reliable and maintainable software solutions.
