FastAPI projections service

Playing with FastAPI, by creating a very over-simplified investment projections service (with projections calculated by Nutmeg's calculator), deployed on Heroku, as part of GitHub Actions CD pipeline; and Docker image also pushed to GitHub packages.

Dev tooling and QA measures used

Tests

1. Unit and integration tests: Executed on Push and PRs, before Docker image is built. Code coverage measured by Codecov.
2. End to end test: Executed on Push and PRs, after Docker image is built, and before it is pushed to GitHub packages; and then once again after Docker image is tagged and pushed to Heroku and service deployed.
3. OWASP API security scan: Executed on Push and PRs, after end-to-end test has run.

Dependency updates

PRs opened for dependency updates by Dependabot Bot and those PRs auto-merged after successful CI checks by Mergify.

Static code analysis

Codeql and OSSAR scans, via GitHub Actions, on Push and PRs.

Pre commit checks
