pysura 0.99.24

A useful tool that provides commands to help ease the installation process of Hasura, and manage its actions, events, and scheduled jobs with baked in phone Auth and a Flutter frontend.

Pysura - BETA

Hasura + Python = Pysura. An open source solution.

Because everyone should be a code wizard.

Requirements:

To deploy Hasura with Pysura with baked in Auth and a templated Flutter Frontend:

• gcloud CLI

• gcloud beta CLI

• A billing account with Google Cloud

• Docker (Make sure it’s running in the background or your deployment will fail!)

• Python 3.9+

• Firebase CLI

• npm

• flutterfire_cli

• Dart

• Flutter

• XCode (for iOS apps) and iOS Dev Tools

• Android Studio (for Android apps) and Android Dev Tools

• Gradle (for Android apps)

pip install pysura
pysura
(pysura_cli) >>> choose_provider
Please choose a provider: [google,]: google
(pysura_cli) >>> setup_pysura

Note: The installer is doing a lot of things. Some of them take a long time, like creating databases, firewalls, and VPC networks. Sometimes it might look frozen, but give it some time to do its thing. It’s automagically building an entire application for you. I promise doing this by hand takes longer. ;)

Is this multi-platform compatible?

Mac - Yes, I developed it on a Mac!

Linux - It should work on Linux, it is untested. Let me know!

Windows - With minor updates it should work. I think the majority of the deployer works, but it might run into issues on the Firebase and Flutterfire CLI’s.

What is Pysura?

Pysura is a CLI tool that’s designed to make building and deploying multi-tenant enterprise grade applications as easy as a freshman year algorithms class. It’s a highly opinionated way because it’s the right way.

It’s kind of like running npm init, if npm was for backends and frontends, it provides your backend, auth, and database for you in the cloud in a way that is infinitely scalable and uses zero-trust, with a type-safe GraphQL backend and a bring-your-own front-end approach with special built-in support for Flutter which is the default setup.

Why Flutter?

So that it doesn’t matter what you are building, you can build it on Pysura. It’s about damn time that Python developers have better mobile support. Let’s bring python to mobile. Let’s bring python to the web. Let’s bring python to the edge. Let’s bring python everywhere. And let’s skin it with Flutter and feed it all the data it wants with GraphQL and Hasura.

Do I have to use Flutter for the frontend? No way! Pysura places firebase in front of your Hasura instance, so if your frontend of choice supports Firebase Auth integrations or libraries, you can use it, or even better open a PR and add a template for your provider.

What is a Pysura Microservice?

It’s a wrapper around a FastAPI app that holds a collection of actions, events, and chron-jobs related to its function. I.e. A payment microservice might have all code related to payment processing. It bakes in Auth with an extra decorator which gives you easy access to the calling user each time a method is called. This works by using opaque tokens that pass through the headers into the microservice. It’s a very simple way to do auth, and it’s very secure. It gives full RBAC at a column level, and you can design rather complex auth rules using Hasura’s permission system. Each action, event, and chron-job is placed in a separate file with routing already handled and the calling users information passed in the calling context. It makes it very easy to build your business logic in a clean, consistent way that is easy to test and maintain, and also easy to hand off to other developers.

Do I need to deploy Hasura with Pysura to use it?

As of right now yes. In the future, no!

Is this just a wrapper for the Hasura CLI?

Pysura does not use the Hasura CLI, and instead manages the metadata directly via retrieving it and overwriting it.

It’s important to note that Pysura will add the local machine of its installer’s IP to the allow-list for the database. This is to allow pysura to connect via pscopg2 for things like table management. You’ll need to de-authorize the network if you want to remove the machine from the allow-list once setup is complete. TODO: Make a deauthorize command.

Limitations:

Currently, this only supports a Google-based deployment/stack. Easily fixable. Just need a fellow AWS/Azure/Etc. wizard who can translate the gcloud commands. I think the portability is pretty high since everything is done from the CLI. The setup wizard is just curling everything.

Neat! But it doesn’t support my cloud provider, when will you be adding AWS/Azure/Etc. support?

I won’t. You can. I built this because I needed it. If our stack changes providers, or potentially if someone was willing to pay for it, I’d be willing to add support for other providers. But as of now, the best bet would be to open a PR and add support for your provider of choice. I tried to design it to be pretty modular. The gcloud –format=json flag is what changed the game when I found it. Maybe try ChatGPT to translate the gcloud commands to AWS/Azure/Etc. commands.

FAQ:

Q: I broke the installer, something wasn’t enabled properly. (I didn’t have docker running, didn’t have gcloud installed, etc.)

A: Best bet is to try to rerun the installer, it might throw some errors but it should recover for the most part. If it doesn’t, then you should trash the project and rerun the setup. Just remember to go to billing and disable the old project, and shut it down.

Q: How do I contribute?

A: Read over the current code, and see if you can make it better. If you can, open a PR. If you can’t, open an issue or a feature request for something that would make it better.

Q: Is this affiliated with Hasura, Google, or Firebase?

A: No, this has no affiliation with Hasura, Google, or Firebase. In no way should this be considered an official product of any of these companies. Although this makes heavy use of tools and API’s provided it is in no way an official product of any company or tool used.

Q: I’m not sure what to enter for one of the command line prompts, what should I do?

A: If you aren’t sure what to enter, most of the time the provided example should work.

Q: One of the choices in the list of options for a prompt doesn’t make sense, or there is something missing!

A: Please open an issue or a feature request. I’m sure I missed some things. Stitching this together required a bit of everything, including working outside my area of expertise.

TODOS:

DONE:

• [x] Add support for Google Cloud

• [x] Add support for Firebase Auth

• [x] Add ios/android wizard

• [x] Add support for Flutter

• [x] Hasura Autodeployer

HIGH PRIORITY:

• [ ] Add table manager @Tristen

• [ ] Add microservice manager @Tristen

• [ ] Add action wizard @Tristen

• [ ] Add event wizard @Tristen

• [ ] Add cron wizard @Tristen

• [ ] Add support for other auth providers (Auth0, etc) @Unclaimed

  • [ ] Auth0

  • [ ] ???

• [ ] Flutter SSR bindings for Web @Unclaimed

• [ ] Caching Wizard @Tristen

• [ ] Update the pysura/pysura_types/root_cmd.py to make better use of prompt_toolkit. It would be nice to have multiple tabs for different level of logs. @Unclaimed

• [ ] Built in API Version Control @Tristen

• [ ] Tighten up the command loops. (Ex. Test the deployer and input values that will fail, and make sure it can recover more gracefully) @Unclaimed

LOW PRIORITY:

• [ ] Add support for AWS/Azure/Etc.

• [ ] Add support for other databases (Postgres, MySQL, BigQuery, etc)

• [ ] Add support for other frontends (React, Vue, etc)

• [ ] Rewrite the CLI tool in a more modular way, with command plug-ins.

• [ ] It should be possible to introspect the entirety of the gcloud CLI by parsing the output of gcloud help. And walking the CLI tool This would allow for a more dynamic CLI tool that could be used for other projects.
