FastAPI CDN host Selector for docs ui

Detail

1. Let's say that the default docs CDN host https://cdn.jsdelivr.net is too slow in your network, while unpkg.com is much faster.

import fastapi_cdn_host
from fastapi import FastAPI

app = FastAPI()
fastapi_cdn_host.patch_docs(app)  # Will use `unpkg.com`(or other faster host) to replace the `cdn.jsdelivr.net/npm`

2. To support offline docs/, put swagger-ui asset files into local directory named static

from pathlib import Path

fastapi_cdn_host.patch_docs(app, Path(__file__).parent.joinpath('static'))

This get the same result of the example in official document: https://fastapi.tiangolo.com/how-to/custom-docs-ui-assets/?h=static#self-hosting-javascript-and-css-for-docs

3. If asset files are ready in private cdn

from fastapi_cdn_host import AssetUrl

fastapi_cdn_host.patch_docs(
    app,
    cdn_host=AssetUrl(
        js='http://my-cdn.com/swagger-ui.js',
        css='http://my-cdn.com/swagger-ui.css',
        redoc='http://my-cdn.com/redoc.standalone.js',
        favicon='http://my-cdn.com/favicon.ico',
    )
)
