Introduction

To develop and host 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 using your email.
  • Active Paid Plan: Ensures dedicated resources and optimized performance for your application. Check our available plans and choose the most suitable for your needs.

​
Creating project

Before starting, make sure you have Node.js and npm installed on your system. If you don’t have them yet, you can download them from the official Node.js website. To create a Nuxt project, you need to install the Nuxt CLI. Run the following command: 
npx nuxi init my-nuxt-app
This command initializes a new Nuxt project in the my-nuxt-app folder.

​
Installing dependencies

Then install the project dependencies: 
cd my-nuxt-app
npm install

​
Developing project

After installing the dependencies, you can start your local development server with: 
npm run dev
Nuxt will start a local development server, usually at http://localhost:3000. To create a simple page, edit the pages/index.vue file:
index.vue
<template>
  <div>
    <h1>Hello from Nuxt!</h1>
  </div>
</template>

​
Building project

Before uploading to Square Cloud, generate the production build: 
npm run build
This creates the .output folder required for running the Nuxt server. Which will contains the MAIN file on this path .output/server/index.mjs

​
Deploying

After preparing your project files, you can now upload them to Square Cloud and host your project. To do so, create a ZIP file containing all your project files.

​
Via dashboard

1

Access the Upload Page

Access the upload page and upload your project zip file.
2

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.
3

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.
Uploading application to Square Cloud

​
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.

Learn more about: how to create the configuration file for Square Cloud.

The squarecloud.app file is a configuration file that will be used to configure your application; it will be used to define your environment.
1

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:
squarecloud update
2

Authenticate

Now, to authenticate and use other CLI commands, you will find your authorization key here by clicking on “Request API Key”. After obtaining your authorization key, run the following command:
squarecloud auth login
3

Upload Your Project

Finally, to deploy your application to Square Cloud using the CLI, you need to run the following command:
squarecloud upload
Or if you created the zip manually, you can use:
squarecloud upload --file <path/to/zip>

​
Troubleshooting

​
Custom Domain

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. See: How to set up your custom domain.

​
Minimum RAM Requirements

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.

​
Could not find this site.

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.
Cloudflare site not found error

​
Site took too long to respond…

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.
Cloudflare request timeout error
