file:// URLs

[mgax]

Are there plans to support local filesystem URLs?

Really surprised to discover this doesn't work.

There might be some security implications.

It's not on my roadmap at the moment, node-fetch sits on server-side and local url usage is limited.

[stevenvachon]

This should work as it works in the browser Firefox.

Edit: This is not defined in the spec https://fetch.spec.whatwg.org/#basic-fetch

[TimothyGu]

I guess we've decided that file:// will not be supported.

[bitinn]

Just to clarify, if this works consistently across major browsers we will re-open.

But more as a clear warning that we don't support file:// protocol, just like we don't support relative url.

@bitinn @TimothyGu I don't I understand the aversion to file:/// urls.

If we're on the server side (using Node.js + Express), and I have to call another rest endpoint whose swagger is not easily obtainable, why can't I take care to put it under source control and simply use it instead of the undownloadable spec from the service I'm calling?

This limitation seems arbitrary. Please clarify its justification.

matthew-andrews@matthewadams That sounds like a problem with how node-fetch is used, not with node-fetch. FYI Node.js v8 will be released with support for file URLs in fs module methods.

The Response constructor can take a Readable stream so why not simply do something like this?

let {Response} = fetch
let stream = fs.createReadStream('myfile.txt')
let promise = new Response(stream).text()

I don't think file protocol should be supported, sorry
I for once use node-fetch as a proxy, user can request any url they want with my api
wouldn't want them to get access to the filesystem...

[stevenvachon]

I don't see why it can't be supported behind an option to enable it.

NB: I'm @matthewadams, not @matthew-andrews. Sorry for the noise, @matthew-andrews

@TimothyGu I'm confused by your response. Please see swagger-api/swagger-js#1044 for justification. Do you have a pointer for Node.js v8 supporting file:// URLs in fs?
