fastapi-static-digest 1.1.0

Static file digest cache busting for FastAPI/Starlette

FastAPI Static Digest

A Starlette/FastAPI plugin to digest and compress static files, and integrate with Jinja templates.

pip install fastapi-static-digest

Overview

There are two classes: StaticDigest and StaticDigestCompiler.

The StaticDigestCompiler.compiler method will produce the digested directory. The StaticDigest (and starlette.staticfiles.StaticFiles) should be configured to read this directory.

The compilation can be added to your build process, for instance with a click CLI command (see below). Alternatively, the FASTAPI_STATICDIGEST_RELOAD=1 environment variable can be set to enable "hot reloading" during development.

Usage

# app.py

app_root = Path(__file__).parent
static_src =  app_root / "static"
static = StaticDigest(source_dir=static_src)

routes = [
    Mount('/static', app=StaticFiles(directory=static.directory), name="static"),
]

app = Starlette(routes=routes)

# manage.py

from .app import app_root


@click.command()
def compile():
    src = app_root / "static"
    click.echo("Source dir %s" % src)
    compiler = StaticDigestCompiler(source_directory=src)
    compiler.compile()
    click.echo("Done.")

Jinja2 Integration

# app.py

app_root = Path(__file__).parent
static_src =  app_root / "static"
static = StaticDigest(source_dir=static_src)
templates = Jinja2Templates(app_root / "templates")
static.register_static_url_for(templates)

routes = [
    Mount('/static', app=StaticFiles(directory=static.directory), name="static"),
]

app = Starlette(routes=routes)

<!-- index.html -->
{{ static_url_for("static", "app.css" )}}
