            <b>Qual porta devo usar para o meu servidor?</b><br />
            Você deve usar a porta <b>80</b> para o seu servidor. A porta 80 é a porta padrão para tráfego HTTP; a Square Cloud a encaminha para 443 (HTTPS) para estabelecer uma conexão segura.<br />
            Certifique-se de configurá-la antes de compactar e enviar seu projeto.
        </Note>;
  }
  return <Note>
            <b>What port should I use for my server?</b><br />
            You should use port <b>80</b> for your server. Port 80 is the default port for HTTP traffic, which is handled by Square Cloud to route it to 443, HTTPS, for a secure connection.<br />
            Make sure to configure it before compressing and uploading your project.

        <b>Wondering how much RAM and CPU your plan needs to host {appType}?</b><br />
        Don't worry, we're here to help.
        Our <a href={url}>{plan}</a> plan offers <b>{tier}GB</b> of RAM and <b>{cpu}vCPU</b>, which should be sufficient for most {appType}. 
        However, if you are working on a larger project and seeking extra stability, we recommend considering our <b>Pro</b> plan. With additional resources, you can maintain stability even during demand spikes.

          Nosso plano <a href={url}>{plan}</a> oferece <b>{tier}GB</b> de RAM e <b>{cpu}vCPU</b>, o que deve ser suficiente para a maioria dos {appType}.
          No entanto, se você estiver trabalhando em um projeto maior e precisar de mais estabilidade, recomendamos considerar nosso plano <b>Pro</b>.
          Com recursos adicionais, você pode manter a estabilidade mesmo durante picos de demanda.

export const appType_0 = "a SolidJS application"

## Introduction

To develop and host {appType_0} on Square Cloud, it's essential to follow a structured sequence of configurations and prerequisites. This technical guide will cover the entire process, from initial setup to production deployment.

### Prerequisites

* **Square Cloud Account**: Register through the [signup page](https://squarecloud.app/en/signup) using your email.
* **Active Paid Plan**: Ensures dedicated resources and optimized performance for your application. Check our [available plans](https://squarecloud.app/en/pricing) and choose the most suitable for your needs.

<RecommendedPlan appType="SolidJS Applications" plan="Standard" tier="4" cpu="4" lang="en" />

## Creating the project

Before you begin, make sure you have Node.js and npm installed on your system.
If you don't have them, you can download them from the [official Node.js website](https://nodejs.org/).

To create a new SolidJS project, run the following command:

```bash theme={null}
npm init solid
```

This command will prompt you to select a template, set a name and other configurations for your new SolidJS project.

### Understanding the Difference between JavaScript and TypeScript

When you choose JavaScript, Solid configures the project with default JavaScript settings. On the other hand, when you choose TypeScript, Solid configures the project with TypeScript settings, including the generation of a `tsconfig.json` file.

## Building the project

Before uploading to production, generate the production artifacts using the build command:

```bash theme={null}
npm run build
```

This command will build your application and create a production-ready version. The output will depend on template or build tool you selected when creating the project.

## Deploying

If you are using Vite as your build tool, see [Vite tutorial](../vite#choosing-a-production-server) for more details on serving the production build.\
If you are using vinxi as your build tool, it comes with a built-in server to serve the production build. You can start the server by editing the `start` script in your `package.json` file to:

```json theme={null}
"scripts": {
  "start": "vinxi start --port 80"
}
```

Then, you can set the following **START** command to start the server:

```bash theme={null}
npm run start
```

### Via dashboard

<Steps>
  <Step title="Access the Upload Page">
    Access the [upload page](https://squarecloud.app/en/dashboard/new) and upload your project zip file.
  </Step>

  <Step title="Configure Your Environment">
    After uploading your zip, you will need to configure the name, main file or runtime environment and other settings for your project.\
    If you are uploading a web project, make sure to select "Web Publication" and set a subdomain to your project.
  </Step>

  <Step title="Deploy Your Project">
    Finally, click on the "Deploy" button to host your project on Square Cloud.\
    After deployment, you can monitor your project's status and logs from the dashboard.

    </Frame>
  </Step>
</Steps>

### Via CLI

To use this method, you need to create a config file named `squarecloud.app` in the root directory of your project. This file will contain the necessary configuration for your project.

<Card title="Learn more about: how to create the configuration file for Square Cloud." icon="link" href="/en/getting-started/config-file">
  The squarecloud.app file is a configuration file that will be used to configure your application; it will be used to define your environment.
</Card>

<Steps>
  <Step title="Install the CLI">
    First, you need to have the CLI installed in your environment. If you don't have it yet, run the following command in your terminal:

    ```
    npm install -g @squarecloud/cli
    ```

    If you already have it, we recommend updating it. To do this, run the following command in your terminal:

    <Tabs>
      <Tab title="Windows">
        ```bash theme={null}
        squarecloud update
        ```
      </Tab>

      <Tab title="Linux, macOS, and WSL">
        ```bash theme={null}
        curl -fsSL https://cli.squarecloud.app/install | bash
        ```
      </Tab>
    </Tabs>
  </Step>

  <Step title="Authenticate">
    Now, to authenticate and use other CLI commands, you will find your authorization key [here](https://squarecloud.app/en/account/security) by clicking on "Request API Key". After obtaining your authorization key, run the following command:

    ```bash theme={null}
    squarecloud auth login
    ```
  </Step>

  <Step title="Upload Your Project">
    Finally, to deploy your application to Square Cloud using the CLI, you need to run the following command:

    ```bash theme={null}
    squarecloud upload 
    ```

    Or if you created the zip manually, you can use:

    ```bash theme={null}
    squarecloud upload --file <path/to/zip> 
    ```
  </Step>
</Steps>

## Troubleshooting

<CardGroup cols={1}>
  ### Custom Domain

  <Card horizontal>
    To use a custom domain (e.g., `mysite.com`) instead of the default URL `mysite.squareweb.app`, you need the **Standard plan or higher**. The subdomain is defined by the **SUBDOMAIN** field in the configuration file.
  </Card>

  ### Minimum RAM Requirements

  <Card horizontal>
    **Minimum: 512MB RAM** for simple websites/APIs. For sites with frameworks (Next.JS, React, Vue, Angular, etc.), we always recommend **at least 1GB RAM**. For larger applications, allocate more RAM to prevent the application from running out of memory and crashing.
  </Card>

  ### Could not find this site.

  <Card horizontal>
    Check if the **subdomain/domain** matches what's configured in the **SUBDOMAIN** field or in the **custom domain settings**. If you just uploaded the site, wait up to **60 seconds** for Square to enable **first access**.
  </Card>

  ### Site took too long to respond...

  <Card horizontal>
    Check if you correctly configured **port 80** and **host 0.0.0.0** in the application. We recommend using Square's forced environment variables: **PORT** and **HOST** from the `.env` file.
  </Card>
