pysura 0.10.74

A Python library used to generate a backend for custom logic using Hasura as a Data-layer

Pysura - BETA

Hasura + Python = Pysura. An open source solution.

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 deploy will fail!)

• Python 3.9+

• Firebase CLI

• npm

• flutterfire_cli

• Dart

• Flutter

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 - I think so, but please let me know!

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 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.

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.

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.
