Can't fetch local file #149

yspotts · 2016-11-30T18:33:09Z

My apologies if this is spelled out somewhere -- I looked through the issues.

I can't seem to direct ReDoc to load my OpenAPI spec from the local filesystem -- only via http. I have tried the following:

<redoc spec-url='swagger.json'></redoc>
<redoc spec-url='file:///Full/Path/swagger.json'></redoc>

in addition to other permutations. However, they all result in this error:

Unable to resolve $ref pointer "file:///<pathname to my spec file>"

Is there any way to have ReDoc load the spec locally?

The text was updated successfully, but these errors were encountered:

RomanHotsiy · 2016-11-30T18:41:37Z

The reason is that the lib I use (json-schema-ref-parser) doesn't support file:/// protocol.

I will fix this but this is not on the next-to-do queue coz this can be workarounded by simply running webserver

yspotts · 2016-11-30T18:42:51Z

@RomanGotsiy thanks for the quick reply! got it

visheshCuriousDev · 2016-12-27T05:29:16Z

@RomanGotsiy Can you tell me how it can be worked around ? Sorry for asking this but i am new to this !!

@yspotts How else did you mention your json file ?

RomanHotsiy · 2016-12-27T06:46:36Z

@vishesh1king just serve your spec and html page via any http-server (e.g. python -m SimpleHTTPServer) so url to it will be: http://127.0.0.1:<someport>/swagger.json not file:///<path>/swagger.json

visheshCuriousDev · 2016-12-27T06:52:32Z

Got it thanks ...
But do you have any format on the json sytax ??
I am uable to load my custom json file ... Its says
" Oops... ReDoc failed to render this spec
this._schema.info is undefined "

This is my main.json file:
{
"links": {
"self": "http://example.com/articles",
"next": "http://example.com/articles?page[offset]=2",
"last": "http://example.com/articles?page[offset]=10"
},

},

}

RomanHotsiy · 2016-12-27T07:00:52Z

@vishesh1king your json file is not in OpenAPI (fka Swagger) format. ReDoc is OpenAPI/Swagger-generated API Reference Documentation. It works only with OpenAPI specs

visheshCuriousDev · 2016-12-27T07:31:35Z

Ohh, I get it now !!! Thanks ...
I saw the file u mentioned in the example "http://petstore.swagger.io/v2/swagger.json" but its in single line ... Could not understand
Do you have any json file that is cleanly indented and works ? I am having trouble at this ? Link to any json file on net that works ?
Thanks again!!

RomanHotsiy · 2016-12-27T08:23:52Z

ReDoc demo spec in yaml format

If you are not familiar with OpenAPI you can start from template spec (direct link). You should also check series of tutorials by API Handyman: http://apihandyman.io/writing-openapi-swagger-specification-tutorial-part-1-introduction/

workaround to have a web server will not work if one needs to send a static html/js documentation to a person that only has a browser ...

hmasila · 2017-07-26T00:15:28Z

Here is what worked for me.

Create OpenAPI/Swagger in swagger.io
Download OpenAPI as JSON
Create a Node.js app with Express. - or any server you are comfortable with
Set an endpoint in the server.js that points to a middleware that mocks the json
Add the newly created endpoint to the <redoc>"http://localhost:5555/api/v1/test</redoc>
Fire up your server
Go to the route where you added redoc
Sit back, relax and enjoy!!

nthx · 2017-07-31T09:56:09Z

@hmasila the reporter clearly stated that the "http://" works for him (and for others too).

This ticket is about "file://" protocol support.
So that we can send a "ZIP" to a person that doesn't have knowledge to run a web server on their computer, or simply has no time to do it.

hmasila · 2017-07-31T10:30:25Z

@nthx I came across this thread when I was working with a local json file. It took me a while to pass it to the redoc tag as http. That is why I wrote my comment. To help any other person who might be in the same situation.

fredbi · 2017-10-29T18:17:08Z

Same issue here.
@RomanGotsiy I have seen you fixed the issue in (json-schema-ref-parser) and asked the pull request to be merged. Thank you so much. Keep us posted.

Fred

DavidMCook · 2017-12-06T17:49:39Z

Hi guys, any news on this merge? I'm one of those people that doesn't want to/have time to set up a local server just to add a local file ref.

fredbi · 2017-12-06T17:56:20Z

I used json-schema-ref-parser recently and it works fine with local refs, even without the "file://" url prefix.

However json-schema-ref-parser.Bundle() is not perfect from resolving remote $refs for swagger, from a documentation point of view. But at least it shoudl work on local refs.

RomanHotsiy · 2018-01-21T22:08:16Z

I have investigated this issue and it seems loading local swagger spec is impossible without running web-server due to same-origin policy and security reasons.

I found other projects have the same issue not resolved, e.g.: https://threejs.org/docs/#manual/introduction/How-to-run-thing-locally.

workaround to have a web server will not work if one needs to send a static html/js documentation to a person that only has a browser ...

I absolutely understand the use case though. There are two possible solutions to this use case:

upload both html and spec to any static hosting so a person with a browser can access it
inject spec directly into html so ReDoc doesn't have to do any network requests (the spec should be bundled beforehand). This variant should be pretty easy after React rewrite is finalized: WIP: Initial React rewrite #357. I think it may be a good idea for an open-source tool. If anyone is willing to write it, let me know and will try to get you started.

If anyone though does know how to load local swagger spec, let me know!

I'm not closing this issue until F.A.Q. is created and this is included there.

philsturgeon · 2018-01-21T22:33:21Z

This would be another argument for rolling redocup into v2.0 as a cli feature. Then the FAQ can read:

Local files will not work, they need a file server to run due to [bla]. If you are working locally and want to see what your redoc will look like, simply use the cli tool: yarn run redoc serve.

Or something. :)

7hibault · 2018-02-02T15:27:33Z

Hi folks, this would be a very useful feature indeed.

Spectacle features this static generation. I'm not sure how it works in detail but maybe it'd be worth checking it out. I think they generate the html on the fly. I'm not familiar enough with ReDoc to know how much this approach is applicable

RomanHotsiy · 2018-06-01T14:46:15Z

redoc-cli has an ability to bundle spec into zero-dependency HTML file.
Docs here: https://github.com/Rebilly/ReDoc/tree/master/cli

monolithed · 2018-09-07T11:29:57Z

@RomanGotsiy how to bundle spec using redoc-cli with custom options and local static files?

<link href="./static/fonts.css" rel="stylesheet" />  <!-- 404 -->
<script src="./static/redoc.standalone.js"> </script>  <!-- 404 -->

<script>
Redoc.init('./scheme/methods.yaml', { // 404
	theme: {
		noAutoAuth: true,
		requiredPropsFirst: true,
		breakpoints: {
			medium: 2
		}
	}
}, document.getElementById('container'))
</script>

monolithed · 2018-09-07T12:21:18Z

These problems for development environment were solved by serve command:

{
	"scripts": {
		"start": "serve"
	},
	"dependencies": {
		"redoc": "^2.0.0-alpha.38",
		"serve": "^10.0.0"
	}
}

But how to build these files into one file — that's a problem!

RomanHotsiy · 2018-09-11T14:30:24Z

From redoc-cli help:

$ redoc-cli bundle --help

redoc-cli bundle <spec>

bundle spec into zero-dependency HTML-file

Positionals:
  spec  path or URL to your spec                                      [required]

Options:
  --help          Show help                                            [boolean]
  --version       Show version number                                  [boolean]
  -t, --template  Path to handlebars page template, see https://git.io/vh8fP
                  for the example                                       [string]
  --options       ReDoc options, use dot notation, e.g. options.nativeScrollbars
  -o, --output    Output file            [string] [default: "redoc-static.html"]
  --title         Page Title           [string] [default: "ReDoc documentation"]
  --cdn           Do not include ReDoc source code into html page, use link to
                  CDN instead                         [boolean] [default: false]

Use --options to provide options:

redoc-cli ... --options.requiredPropsFirst --options.theme.breakpoints.medium=2

or

 redoc-cli ... --options="{\"requiredPropsFirst": true }"

For template use --template, check the default template for the reference: https://git.io/vh8fP

okeyokoro · 2020-03-16T17:57:07Z

passing the local spec_file path to the redoc docker container is also a really convenient route (if you have docker installed)

docker run -it --rm -p 81:80 \
  -v $(pwd)/<SPEC_FILE>:/usr/share/nginx/html/<SPEC_FILE> \
  -e SPEC_URL=<SPEC_FILE> redocly/redoc

# visit localhost:81 in your browser

source https://hub.docker.com/r/redocly/redoc

cah-alexsukhodolsky · 2020-04-03T13:33:44Z

I just found a neat little web server that runs in your browser. It can easily point to a local folder and serve up your http file with redoc standalone with a reference to a local swagger file:
