Why has the sendFile function disappeared from the documentation?

Yo!

Thanks for all the hard work.

I just noticed some discrepancies between your documentation and type definitions around the crucial sendFile function. It is not there:

My issue is that I'm running a video site, using this sendFile functionality heavily, and they can't view the video anymore. The filename and extension are missing.

Until then,
M.

Methods on the website are sorted alphabetically. You can find the documentation for res.sendFile() between res.send() and res.sendStatus()
https://expressjs.com/en/5x/api.html#res.sendFile

BTW expressjs.com website has its own repository expressjs/expressjs.com

Thank you, @krzysdz ... well, it's not in the sidebar on your public website:

Then, where are the types?

[krzysdz]

The sidebar is scrollable, but it looks like your browser hides the scrollbar.

As for types, most can be deduced from the text:

• path - string
• options - object with the following properties:
  • maxAge - number or string (described in text)
  • root - string
  • lastModified - bool
  • headers - object with keys being HTTP header names and values are their respective values
  • dotfiles - one of "allow", "deny", "ignore"
  • acceptRanges - bool
  • cacheControl - bool
  • immutable - bool
• fn - function which accepts err as argument

If you need TypeScript type definitions, those can be installed from @types/express package. The DefinitelyTyped type definition for res.sendFile() is here.

@krzysdz Thanks but no, your official Express.js page still does not show the sendFile function:

What server and cache mechanism do you use?

If you need TypeScript type definitions, those can be installed from @types/express package.
Well, they still point to v5.0.1 ...

The link to res.sendFile() has been there in 5.x docs since these docs were created. If you want to make sure that the link really is there, you can use this selector #res-menu>li>a[href='#res.sendFile'] to find it.

What server and cache mechanism do you use?

From the website's repository readme:

It is hosted directly from the repository as a GitHub Pages website.

Thanks. I think the confusion was that the sendFile exists in the document but not in the sidebar:

@binarykitchen what browser are you using? Seems like the scroll bar is not properly render.

Note: It is hard to see but there are two scroll bars. I am using Chrome@135.

[binarykitchen]

Ah, yes, there are two scroll bars. I can see now. The inner one was almost invisible.

Hmm, having two scroll bars is not a good user experience. I would redesign this part.
