Logging setup for FastAPI

This logging setup configures Structlog to output pretty logs in development, and JSON log lines in production.

Then, you can use Structlog loggers or standard logging loggers, and they both will be processed by the Structlog pipeline (see the hello() endpoint for reference). That way any log generated by your dependencies will also be processed and enriched, even if they know nothing about Structlog!

Requests are assigned a correlation ID with the asgi-correlation-id middleware (either captured from incoming request or generated on the fly). All logs are linked to the correlation ID, and to the Datadog trace/span if instrumented. This data "global to the request" is stored in context vars, and automatically added to all logs produced during the request thanks to Structlog. You can add to these "global local variables" at any point in an endpoint with `structlog.contextvars.bind_contextvars(custom

Import CustomElements from .html files

This is the technical implementation of the idea and concept described in my article “Why don’t we use HTML to author web components?”

Instead of using template literals, constructors and other specifics to define CustomElements, this is a proposal to just use standard HTML to define CustomElements.

The goal is to import CustomElements like this:

Tradeoffs in value-derived types in TypeScript

Many of the more "advanced" typescript features can be used for creating "value-derived" types.

At its simplest form:

let vehicle = { name: "Van", wheels: 4 }
