# Getting Started on Square Cloud with Go

> Learn how to get started on Square Cloud with Go

## 🚀 Introduction

* Before getting started, ensure that Go is installed on your system. If you don't have it yet, you can download it from the [official Go website](https://go.dev/doc/install).
* Next, you will need to create an account on Square Cloud, which can be done through the [login page](https://squarecloud.app/en/signup). You can use your email, GitHub, or both to create the account.
* Finally, you need to have an active paid plan on your account. You can view our plans and purchase one according to your needs [here](https://squarecloud.app/en/pricing).

## ⚙️ squarecloud.app file configuration

<Note>
  If you are uploading your application via the Square Cloud website, you can ignore this section. The site automatically creates the `squarecloud.app` configuration file for you.
</Note>

<Card title="Learn more: how to create the configuration file for Square Cloud." icon="link" href="https://docs.squarecloud.app/en/getting-started/config-file">
  The squarecloud.app file is a configuration file that will be used to
  configure your application; it will serve to define the name, description,
  version, main file, among other things.
</Card>

## 📄 Required Files

* main.go (Example of main file).
* go.mod (Dependencies file).
* OR go.work (Dependencies file).
* go.sum (Checksum file, optional).
* [squarecloud.app](https://docs.squarecloud.app/en/getting-started/config-file) (file containing Square Cloud configuration).

## ▶️ How to start your application

* If the `START` field is not defined in the configuration file, Square Cloud will execute `go run MAIN` to compile and run the Go file specified in `MAIN`. If the `START` field is defined, the value in it will be executed directly. For more information about configuration file parameters, visit [configuration parameters](https://docs.squarecloud.app/en/getting-started/config-file#configuration-parameters).

* Square Cloud runs the `go mod tidy` command to update project dependencies.

## 🖥️ Preparing the project

Before hosting your project on Square Cloud, first check if the project files are properly configured for hosting.

<Warning>The configuration file (`squarecloud.app/.config`) must be located at the root of the zip file. Otherwise, Square Cloud will not be able to find it during deploy.</Warning>

## 📤 How to host your project

Now that you have prepared all the files for your Go project, the next step is to upload them to Square Cloud and put your application online. There are several ways to upload, but we will cover two: via Dashboard or via CLI.

### 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.

  The squarecloud.app file is a configuration file that will be used to configure your application; it will be used to define your environment.

<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>
