## 🚨 DEPRECATION WARNING 🚨

As [**FastAPI**](https://github.com/tiangolo/fastapi) and the [equivalent project generator](https://github.com/tiangolo/full-stack-fastapi-postgresql) provide a much better solution to all the use cases this project was built for, all the future development will be done there.

You are still free to use this project, but it won't receive any new features, changes, or bug fixes.

If you are starting a new project from scratch, check the alternatives at the [FastAPI docs: Project Generation](https://fastapi.tiangolo.com/project-generation/).

# Full Stack Flask and PostgreSQL - Base Project Generator

[![Build Status](https://travis-ci.org/tiangolo/full-stack.svg?branch=master)](https://travis-ci.org/tiangolo/full-stack)

Generate a backend and frontend stack using Python, including interactive API documentation.

[![Screenshot](https://raw.githubusercontent.com/tiangolo/full-stack/master/screenshot.png)](https://github.com/tiangolo/full-stack)

## Notice: Flask or [FastAPI](https://github.com/tiangolo/fastapi)

If you are using this project (or Flask in general to create web APIs) you would probably benefit more from [FastAPI](https://github.com/tiangolo/fastapi).

You can use the equivalent sibling project generator based on **FastAPI**: [https://github.com/tiangolo/full-stack-fastapi-postgresql](https://github.com/tiangolo/full-stack-fastapi-postgresql). It also has more features than this one.

**FastAPI** was created from the learnings acquired while creating and using these project generators for Flask, with all the plug-ins and ideas.

* **FastAPI** (and its project generators), would give you about 800% (8x) the performance achievable with this one.
* Writing code in **FastAPI** is about 200% to 300% faster. Because you write a lot less code, it is designed for web APIs, and you have auto-complete everywhere.
* About 40% of the human (developer) induced errors can be reduced (**FastAPI** does a lot of the data validation, conversion and documentation for you).

---

## Features

* Full **Docker** integration (Docker based)
* Docker Swarm Mode deployment
* **Docker Compose** integration and optimization for local development
* **Production ready** Python web server using Nginx and uWSGI
* Python **Flask** backend with:
  * **Flask-apispec**: Swagger live documentation generation
  * **Marshmallow**: model and data serialization (convert model objects to JSON)
  * **Webargs**: parse, validate and document inputs to the endpoint / route
  * **Secure password** hashing by default
  * **JWT token** authentication
  * **SQLAlchemy** models (independent of Flask extensions, so they can be used with Celery workers directly)
  * Basic starting models for users and groups (modify and remove as you need)
  * **Alembic** migrations
  * **CORS** (Cross Origin Resource Sharing)
* **Celery** worker that can import and use models and code from the rest of the backend selectively (you don't have to install the complete app in each worker)
* REST backend tests based on **Pytest**, integrated with Docker, so you can test the full API interaction, independent on the database. As it runs in Docker, it can build a new data store from scratch each time (so you can use ElasticSearch, MongoDB, CouchDB, or whatever you want, and just test that the API works)
* Easy Python integration with **Jupyter Kernels** for remote or in-Docker development with extensions like Atom Hydrogen or Visual Studio Code Jupyter
* Vue frontend:
  * Generated with **Vue CLI**
  * JWT Authentication handling
  * Login view
  * After login, main dashboard view
  * **Vuex**
  * **Vue-router**
  * **Vuetify** for beautiful material design components
  * **TypeScript**
  * Docker server based on **Nginx** (configured to play nicely with Vue-router)
  * Docker multi-stage building, so you don't need to save or commit compiled code
  * Frontend tests ran at build time (can be disabled too)
  * Made as modular as possible, so it works out of the box, but you can re-generate with Vue CLI or create it as you need, and re-use what you want
* **PGAdmin** for PostgreSQL database, you can modify it to use PHPMyAdmin and MySQL easily
* **Swagger-UI** for live interactive documentation
* **Flower** for Celery jobs monitoring
* Load balancing between frontend and backend with **Traefik**, so you can have both under the same domain, separated by path, but served by different containers
* Traefik integration, including Let's Encrypt **HTTPS** certificates automatic generation
* **GitLab CI** (continuous integration), including frontend and backend testing

## How to use it

Go to the directoy where you want to create your project and run:

```bash
pip install cookiecutter
cookiecutter https://github.com/tiangolo/full-stack
```

### Generate passwords

You will be asked to provide passwords and secret keys for several components. Open another terminal and run:

```bash
openssl rand -hex 32
# Outputs something like: 99d3b1f01aa639e4a76f4fc281fc834747a543720ba4c8a8648ba755aef9be7f
```

Copy the contents and use that as password / secret key. And run that again to generate another secure key.

### Input variables

The generator (cookiecutter) will ask you for some data, you might want to have at hand before generating the project.

The input variables, with their default values (some auto generated) are:

* `project_name`: The name of the project
* `project_slug`: The development friendly name of the project. By default, based on the project name
* `domain_main`: The domain in where to deploy the project for production (from the branch `production`), used by the load balancer, backend, etc. By default, based on the project slug.
* `domain_staging`: The domain in where to deploy while staging (before production) (from the branch `master`). By default, based on the main domain.

* `docker_swarm_stack_name_main`: The name of the stack while deploying to Docker in Swarm mode for production. By default, based on the domain.
* `docker_swarm_stack_name_staging`: The name of the stack while deploying to Docker in Swarm mode for staging. By default, based on the domain.

* `secret_key`: Backend server secret key. Use the method above to generate it.
* `first_superuser`: The first superuser generated, with it you will be able to create more users, etc. By default, based on the domain.
* `first_superuser_password`: First superuser password. Use the method above to generate it.
* `backend_cors_origins`: Origins (domains, more or less) that are enabled for CORS (Cross Origin Resource Sharing). This allows a frontend in one domain (e.g. `https://dashboard.example.com`) to communicate with this backend, that could be living in another domain (e.g. `https://api.example.com`). It can also be used to allow your local frontend (with a custom `hosts` domain mapping, as described in the project's `README.md`) that could be living in `http://dev.example.com:8080` to cummunicate with the backend at `https://stag.example.com`. Notice the `http` vs `https` and the `dev.` prefix for local development vs the "staging" `stag.` prefix. By default, it includes origins for production, staging and development, with ports commonly used during local development by several popular frontend frameworks (Vue with `:8080`, React, Angular).
 
* `postgres_password`: Postgres database password. Use the method above to generate it. (You could easily modify it to use MySQL, MariaDB, etc).
* `pgadmin_default_user`: PGAdmin default user, to log-in to the PGAdmin interface.
* `pgadmin_default_user_password`: PGAdmin default user password. Generate it with the method above.
 
* `traefik_constraint_tag`: The tag to be used by the internal Traefik load balancer (for example, to divide requests between backend and frontend) for production. Used to separate this stack from any other stack you might have. This should identify each stack in each environment (production, staging, etc).
* `traefik_constraint_tag_staging`: The Traefik tag to be used while on staging. 
* `traefik_public_network`: This assumes you have another separate publicly facing Traefik at the server / cluster level. This is the network that main Traefik lives in.
* `traefik_public_constraint_tag`: The tag that should be used by stack services that should communicate with the public.

* `flower_auth`: Basic HTTP authentication for flower, in the form`user:password`. By default: "`root:changethis`".

* `sentry_dsn`: Key URL (DSN) of Sentry, for live error reporting. If you are not using it yet, you should, is open source. E.g.: `https://1234abcd:5678ef@sentry.example.com/30`.

* `docker_image_prefix`: Prefix to use for Docker image names. If you are using GitLab Docker registry it would be based on your code repository. E.g.: `git.example.com/development-team/my-awesome-project/`.
* `docker_image_backend`: Docker image name for the backend. By default, it will be based on your Docker image prefix, e.g.: `git.example.com/development-team/my-awesome-project/backend`. And depending on your environment, a different tag will be appended ( `prod`, `stag`, `branch` ). So, the final image names used will be like: `git.example.com/development-team/my-awesome-project/backend:prod`.
* `docker_image_celeryworker`: Docker image for the celery worker. By default, based on your Docker image prefix.
* `docker_image_frontend`: Docker image for the frontend. By default, based on your Docker image prefix.

## How to deploy

This stack can be adjusted and used with several deployment options that are compatible with Docker Compose, but it is designed to be used in a cluster controlled with pure Docker in Swarm Mode with a Traefik main load balancer proxy handling automatic HTTPS certificates, using the ideas from <a href="https://dockerswarm.rocks" target="_blank">DockerSwarm.rocks</a>.

Please refer to <a href="https://dockerswarm.rocks" target="_blank">DockerSwarm.rocks</a> to see how to deploy such a cluster in 20 minutes.

## More details

After using this generator, your new project (the directory created) will contain an extensive `README.md` with instructions for development, deployment, etc. You can pre-read [the project `README.md` template here too](./{{cookiecutter.project_slug}}/README.md).

## History

**Note about Angular**: a previous version of this project generated a basic default Angular frontend application, but without any view or interaction with the rest of the stack (the backend API). I recently switched to Vue for frontend and used it to created the basic frontend views for this project (that didn't exist before). If you are interested in keeping the Angular version, let me know in an issue, I can create an Angular version of the project (without the current default views), then you can integrate your Angular app with the basic `Dockerfile` and additional files.

This project was based on [senseta-os/senseta-base-project](https://github.com/senseta-os/senseta-base-project).

As [I was the only maintainer](https://github.com/tiangolo), I'm continuing the development in this fork (https://github.com/tiangolo/full-stack).
