Features

  • Full Docker integration (Docker based).
  • Docker Swarm Mode deployment.
  • Docker Compose integration and optimization for local development.
  • Production ready Python web server using Uvicorn and Gunicorn.
  • Python FastAPI backend with:
    • Fast: Very high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic).
    • Intuitive: Great editor support. Completion everywhere. Less time debugging.
    • Easy: Designed to be easy to use and learn. Less time reading docs.
    • Short: Minimize code duplication. Multiple features from each parameter declaration.
    • Robust: Get production-ready code. With automatic interactive documentation.
    • Standards-based: Based on (and fully compatible with) the open standards for APIs: OpenAPI and JSON Schema.
    • Many other features including automatic validation, serialization, interactive documentation, authentication with OAuth2 JWT tokens, etc.
  • Secure password hashing by default
  • JWT token authentication
  • CORS (Cross Origin Resource Sharing)
  • Celery worker that can import and use code from the rest of the backend selectively (you don't have to install the complete app in each worker).
  • NoSQL Couchbase database that supports direct synchronization via Couchbase Sync Gateway for offline-first applications.
  • Full Text Search integrated, using Couchbase.
  • 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, 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.
  • Email notifications for account creation and password recovery, compatible with:
    • Mailgun
    • SparkPost
    • SendGrid
    • ...any other provider that can generate standard SMTP credentials.
  • Vue frontend:
    • Generated with Vue CLI.
    • JWT Authentication handling.
    • Login view.
    • After login, main dashboard view.
    • Main dashboard with user creation and edition.
    • Self user edition.
    • 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.
  • 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:

pip install cookiecutter
cookiecutter https://github.com/tiangolo/full-stack-fastapi-couchbase

Generate passwords

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

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).

  • couchbase_user: Couchbase main user to be used by the application (code). By default admin.

  • couchbase_password: Password of the main user, for the backend code. Generate it with the method above.

  • couchbase_sync_gateway_cors: List of CORS origins that the Sync Gateway should allow to talk to directly. Similar to backend_cors_origins.

  • couchbase_sync_gateway_user: User to be created for the Couchbase Sync Gateway. This is what allows synchronization using the CouchDB protocol, with Couchbase Lite in mobile apps and PouchDB in the web and hybrid mobile apps.

  • couchbase_sync_gateway_password: Couchbase Sync Gateway 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 formuser: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.

  • docker_image_sync_gateway: Docker image for the Sync Gateway. 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 DockerSwarm.rocks.

Please refer to DockerSwarm.rocks 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.
