Cannot use JSX unless the '--jsx' flag is provided
Published: 2023-11-22 01:45:28


![Image description](https://media.tenor.com/6_WnWYsDeMMAAAAC/what-to-do-grinch.gif)

The error message "Cannot use JSX unless the '--jsx' flag is provided" typically occurs when you're working with TypeScript and trying to use JSX syntax without specifying the JSX option in your TypeScript configuration.

To resolve this issue, you need to ensure that your TypeScript configuration includes the appropriate JSX option. Here's how you can do that:

**tsconfig.json**:
Open your tsconfig.json file, which is typically located at the root of your TypeScript project. If you don't have a tsconfig.json file, you can create one.

Add JSX Option:
Make sure your **tsconfig.json** includes the "**jsx**" option. It should look something like this:


```
{
  "compilerOptions": {
    "target": "es6", // or your target version
    "module": "commonjs", // or your module system
    "jsx": "react", // or "preserve" if you're using another JSX-compatible library
    // other compiler options...
  },
  // other configuration options...
}
```

The important line here is "jsx": "react". This specifies that you are using JSX syntax with React. If you are using a different JSX-compatible library, you might need to adjust this value accordingly.

Save the File:
Save the tsconfig.json file after making these changes.

Restart the TypeScript Server (if applicable):
If you have a TypeScript server running (for example, if you're using Visual Studio Code with the TypeScript extension), you might need to restart it for the changes to take effect.

After making these changes, the error should be resolved, and you should be able to use JSX syntax in your TypeScript files without encountering the "--jsx" flag error.

MY Start to IT
Tags: beginners, career, google
Published: 2023-11-21 22:41:08

I am just starting my IT journey and let me say I am nervous and excited. As someone with a large background in hospitality, customer service, and marketing, this is a huge pivot for me. I often question if this is the right choice, but I am certain that it is something I want to do.

I want to join a IT career, because I love technology. I use it every day and it is constantly changing. I first began my journey when I watched my sister switch careers from finance to IT without a degree and loving it. It made me realize that I don't need to get a 4 year degree in information technology just to do something I love, so I began the google IT support course and I am currently on the second module. It takes a lot of consistency and determination, but I will not falter. 

I will continue to track my progress in IT in these posts and I hope that this will help others who are scared of taking that leap of faith or pivot in their careers. I also hope to be able to look back on these post and say "wow I have come so far, look at me now."

Why battery life is a crucial factor in choosing a laptop
Published: 2023-11-22 01:10:44

## Introduction: The Importance of Battery Life

As technology advances, the demand for laptops is also on the rise. One major feature that many laptop buyers prioritize is the battery life. With the increasing need for portability, battery life is a crucial factor to consider when selecting a laptop. The longer the battery life of a laptop, the longer you can work without plugging it in or searching for a power source.

## Battery Life and Productivity

The importance of battery life in selecting a laptop is clear when considering its impact on productivity. Long-lasting battery life means less time spent searching for a power source and more time getting work done. You can now work longer hours without worrying about losing your work due to sudden power outages. A laptop with a solid battery life allows you to focus on work and not getting stuck in unexpected situations.

## Battery Life and Travel

Another reason why battery life is a crucial factor in choosing a laptop is travel. For people who frequently travel, a long battery life is a necessary feature. A laptop with excellent battery life enables you to work long hours on the go without worrying about finding a power source. Moreover, it provides the ability to manage time efficiently as you don’t have to allocate time for charging your machine.

## Battery Life and the Environment

Today, environmental concerns have become a significant source of discussion around the world. Environmental sustainability has become a priority for many people. Battery life is also connected to environmental sustainability; the longer a laptop battery life, the less energy consumption and the smaller the carbon footprint. Investing in a laptop with a good battery life is not only beneficial for your productivity and convenience, but it is also beneficial for the environment.

## Conclusion

Battery life is a crucial factor in choosing a laptop. It has a direct impact on your productivity, convenience, and the environment. Heavy users and frequent travelers need machines with extended [battery life](https://www.cinverter.com/blogs/news/e-scooter-commuting-tips?utm_source=dev_to&utm_medium=rankking) periods. A laptop with a good battery life enhances productivity, enables efficient time management, and sustainability.

UseState why?
Tags: usestate, beginners, javascript, tutorial
Published: 2023-11-22 00:56:56

Understanding useState:
The useState hook allows us to add state to functional components without the need for class-based components. It provides a more effective way of managing state compared to directly modifying variables for rendering reasons.

Let's consider a simple example to understand why useState is preferred over changing variables directly for rendering:

```javascript
import React, { useState } from "react";

const StateManipulation = () => {
  let counter = 0;

  const increment = () => {
    counter++;
  };

  return (
    <div>
      {counter}
      <button onClick={increment}>Increment</button>
    </div>
  );
};
```

In this example, we have a `counter` variable that is incremented when the button is clicked. However, modifying the `counter` variable directly does not trigger a re-render of the component. As a result, the updated value of `counter` will not be reflected in the UI.

By using useState, we ensure that when the state is updated, React knows to re-render the component and update the UI accordingly. Let's see how the same example can be modified to use useState:

```javascript
import React, { useState } from "react";

const StateManipulation = () => {
  const [counter, setCounter] = useState(0);

  const increment = () => {
    setCounter(counter + 1);
  };

  return (
    <div>
      {counter}
      <button onClick={increment}>Increment</button>
    </div>
  );
};
```

In this modified version, we use the useState hook to create a state variable `counter` and its corresponding setter function `setCounter`. By calling `setCounter` with the updated value of `counter`, React knows that the state has changed and triggers a re-render, updating the UI with the new value.

Benefits of useState over direct variable modification:
- Automatic Re-rendering: Using useState ensures that the component re-renders when the state is updated, reflecting the changes in the UI.
- React's Virtual DOM: React efficiently updates only the necessary parts of the UI that have changed, optimising performance.
- State Management: useState provides a clear and structured approach to manage component-level state, making the code more maintainable and easier to understand.

UseState is particularly beneficial as it triggers automatic re-rendering, ensuring that state updates are reflected in the UI. By embracing the useState hook, you can build robust and maintainable React components.

Happy coding!
Livewire: The best of both worlds

<hr/>
## One project



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/31ttcua3095wlso3n9mw.png)






During the first web wave, you have heard about the MVC pattern. There was some technical limitations at that time to deliver a better user experience (UX): slow page transitions, "poor" interfaces and awful usability.

Ah, and we had the spaghetti style with some database queries inside views. But this was the programmers' fault, not a fault from the MVC pattern itself.

But... it worked out at the end of the day! It was **one project.**

<hr/>

## Two projects 



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7r7ko8xmq9mnrl27gfwm.png)



After the condemnation of the MVC pattern, modern frontend frameworks such as Vue, React and Angular rapidly emerged... now the application loads faster, full page reloads are not required anymore and users experience a better UX. You know it as SPA (Single Page Application).


By nature, a SPA imposes the concept of separation between frontend and backend. Now, you have **two projects**.


Then, every single time that the frontend needs some new data the backend needs to be improved. And now you get:

-  **Two repositories** to manage.
-  **Two deploy pipelines** to manage.
-  **Two teams** to manage.


Not to mention that it is necessary **to duplicate**:

- Authentication.
- Authorization.
- Some parts of business rules.

Because, well... they are two different projects.


The pieces are separated but intimately linked. In the end, this is just **one product splitted in two projects**.


<hr/>

## One project (again)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0z4tvc265mhz918ivaex.png)


What if it was possible to make things simple again?

- **One deploy pipeline** to manage.
- **One team** to manage.
- **One project** (again).


Now enters [Livewire](https://livewire.laravel.com): a full-stack framework for Laravel that takes the pain out of building dynamic UIs. 

You can go right away to the docs and find out by yourself how productive you can be.

If you have previously worked with Vue/React/Angular you will quickly notice something: where are the UI components libraries?


Well, there are not that many libraries available for Livewire. But, now you have [MaryUI](https://mary-ui.com): great **DX** and **UX** with **minimal effort**.

<hr />

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wn792jyk1vttpgcs0sel.gif)


<hr/>

## Conclusion 


A puzzle becomes easier to put together when the pieces are close enough to each other. Keep things simple and avoid complexity at all costs.

Remember that using Livewire will not stop people from making the same mistakes as they did in the past.

How to use unique_index wisely to grasp our business logic
Tags: ecto, elixir, erlang, phoenix
Published: 2023-11-22 00:20:53

How do you ensure a unique index when the user tries to get more than one ticket for a paid conference? And the user gets multiple tickets for a free conference?

What are our goals here?

- sent **paid** conference to **_`Ticket.changeset/1`_** to ensure the **_`status: :paid`_**, create one.
- sent **free** conference to **_`Ticket.changeset/1`_** to ensure the **_`status: :free`_**, create many.

How can we apply these to our business logic:
```elixir
create table(:tickets) do
  add :conference_id, references(:conferences), null: false
  add :user_id, references(:users), null: false
  add :status, :string, null: false, default: "free"
end

create unique_index(:tickets, [:conference_id, :user_id, :status], where: "status = 'paid'")
```

Now, how can we test?
```elixir
iex> Ticket.changeset(%{conference: %{is_paid: false}, user: %{...}, status: :free}) |> Repo.insert()
[debug] QUERY OK
{:ok, 
  %Ticket%{id: 1, status: :free, conference_id: 1, user_id: 1}
}
iex> Ticket.changeset(%{conference: %{is_paid: false}, user: %{...}, status: :free}) |> Repo.insert()
[debug] QUERY OK
{:ok, 
  %Ticket%{id: 2, status: :free, conference_id: 1, user_id: 1}
}
iex> Ticket.changeset(%{conference: %{is_paid: true}, user: %{...}, status: :paid}) |> Repo.insert()
[debug] QUERY OK
{:ok, 
  %Ticket%{id: 3, status: :paid, conference_id: 2, user_id: 1}
}
iex> Ticket.changeset(%{conference: %{is_paid: true}, user: %{...}, status: :paid}) |> Repo.insert()
[debug] QUERY ERROR
** (Ecto.ConstraintError)
```

Awesome!

Data Structures and Algorithms: Linked Lists
Tags: datastructures, beginners, webdev
Published: 2023-11-22 00:18:09

A linked list is a data structure that consists of a chain of nodes, where each node contains some data and a pointer to the next node in the list. 


![Linked List Node](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/j5yje2zpkuzm4y7b7nci.png)

The first node in a linked list is referred to as the Head whilst the last node is referred to as the Tail. We can reference the position of each node in a linked list similarly to the way we reference position in arrays, where the Head has an index of zero. The tail of a linked list always points to null. 

The example below shows a simple linked list containing integers. 
![Simple linked list](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/lawu2agpnet880yi8g9e.png)

It is worth noting that each node will only reference the following node, and not the node(s) that came before it. This means that a linked list can only be transversed in one direction. 

<u>Advantages</u>

- Elements can be easily added or removed without reorganising the entire structure.
- Dynamic size, that is to say that the linked list can grow or shrink on demand.
- No wasted memory at run time, as only the amount of memory for the nodes will be used, increasing or decreasing as necessary.

<u>Disadvantages</u>

- Random access is not feasible as one would have to traverse the linked list from the beginning whenever one wants to find a specific node. 
- Searching a linked list can be time consuming, having linear time complexity: O(n). 
- Traversal is only possible in one direction
