Reflex Cloud - Quick Start

So far, we have been running our apps locally on our own machines. But what if we want to share our apps with the world? This is where the hosting service comes in.

Quick Start

Reflex’s hosting service makes it easy to deploy your apps without worrying about configuring the infrastructure.

Prerequisites

Hosting service requires reflex>=0.6.6.
This tutorial assumes you have successfully reflex init and reflex run your app.
Also make sure you have a requirements.txt file at the top level app directory that contains all your python dependencies! (To create a requirements.txt file, run pip freeze > requirements.txt.)

Authentication

First run the command below to login / signup to your Reflex Cloud account: (command line)

You will be redirected to your browser where you can authenticate through Github or Gmail.

Web UI

Once you are at this URL and you have successfully authenticated, click on the one project you have in your workspace. You should get a screen like this:

This screen shows the login command and the deploy command. As we are already logged in, we can skip the login command.

Deployment

Now you can start deploying your app.

In your cloud UI copy the reflex deploy command similar to the one shown below.

In your project directory (where you would normally run reflex run) paste this command.

The command is by default interactive. It asks you a few questions for information required for the deployment.

The first question will compare your requirements.txt to your python environment and if they are different then it will ask you if you want to update your requirements.txt or to continue with the current one. If they are identical this question will not appear. To create a requirements.txt file, run pip freeze > requirements.txt.
The second question will search for a deployed app with the name of your current app, if it does not find one then it will ask if you wish to proceed in deploying your new app.
The third question is optional and will ask you for an app description.

That’s it! You should receive some feedback on the progress of your deployment and in a few minutes your app should be up. 🎉

For detailed information about the deploy command and its options, see the Deploy API Reference and the CLI Reference.

Once your code is uploaded, the hosting service will start the deployment. After a complete upload, exiting from the command does not affect the deployment process. The command prints a message when you can safely close it without affecting the deployment.

If you go back to the Cloud UI you should be able to see your deployed app and other useful app information.
