First check

• I added a very descriptive title to this issue.
• I used the GitHub search to find a similar issue and didn't find it.
• I searched the FastAPI documentation, with the integrated search.
• I already searched in Google "How to X in FastAPI" and didn't find any information.
• I already read and followed all the tutorial in the docs and didn't find an answer.
• I already checked if it is not related to FastAPI but to Pydantic.
• I already checked if it is not related to FastAPI but to Swagger UI.
• I already checked if it is not related to FastAPI but to ReDoc.
• After submitting this, I commit to one of:
  • Read open issues with questions until I find 2 issues where I can help someone and add a comment to help there.
  • I already hit the "watch" button in this repository to receive notifications and I commit to help at least 2 people that ask questions in the future.
  • Implement a Pull Request for a confirmed bug.

Example

I want to self-host all resource but I can't find any document change logo swagger
I only see https://fastapi.tiangolo.com/advanced/extending-openapi/ to host js and css

I want to change <link rel="shortcut icon" href="https://fastapi.tiangolo.com/img/favicon.png"> store in my host

Moreover, does anyone help me link to custom template,... swagger and redoc? Thanks

You can override the default redoc_url and docs_url, then you can create your own endpoint. Which you can customize however if you want.

from fastapi import FastAPI
from fastapi.openapi.docs import get_swagger_ui_html, get_redoc_html


app = FastAPI(docs_url=None, redoc_url=None)


@app.get("/docs", include_in_schema=False)
def overridden_swagger():
	return get_swagger_ui_html(openapi_url="/openapi.json", title="FastAPI", swagger_favicon_url="https://placekitten.com/200/300")

@app.get("/redoc", include_in_schema=False)
def overridden_redoc():
	return get_redoc_html(openapi_url="/openapi.json", title="FastAPI", redoc_favicon_url="https://placekitten.com/200/300")

Sorry for the long delay! 🙈 I wanted to personally address each issue/PR and they piled up through time, but now I'm checking each one in order.
