Deep links to operations are broken when tags contain spaces and doc expansion is 'none'

Q&A

• OS: macOS
• Browser: Chrome
• Version: 3.20
• Swagger/OpenAPI version: Swagger 2.0

Content & configuration

Use example swagger spec with spaces in the operations:

https://raw.githubusercontent.com/pablocoberly/misc/master/swagger_spaces.json

Initialise swagger bundle with docexpansion set to 'none'

Describe the bug you're encountering

When a swagger spec contains tags that have spaces, and doc expansion is disabled, the deep links to operations don't work.

To reproduce...

Steps to reproduce the behavior:

1. Use a spec that has a spaces in the tags, e.g. https://raw.githubusercontent.com/pablocoberly/misc/master/swagger_spaces.json
2. Initialise the swagger setting:

docExpansion: 'none',

3. Link to an operation that uses a tag with a space in it (e.g. #/Store%2520Space)
4. The operation is not "scrolled to".

Expected behavior

The operation should be expanded be scrolled to even if the operation has a space in it.

Additional context or thoughts

• Attempt to fix in bug(deeplinking): escaping is breaking whitespaces & underscored tags/ids #4953
• Deep linking does not work for operations with tags containing spaces #4120
• Invalid HTML ID for Operations with tags which contain multiple words #4537

Hi @pablocoberly!

This is intentional - spaces are represented as %20 in URL fragments, and as _ in id attributes, which users use as CSS selectors.

It seems that the functionality is working (link below), so I'm not sure what the issue is here - are you just saying that, per HTML semantics, the fragment should match the element ID?

Hi, @shockey No I'm saying that it deep linking still doesn't work for me in 3.20. Let me come up with a better example that uses a different default swagger spec.

[shockey]

@pablocoberly ah, I see - that's not good!

Deep linking should be working for all types of tags - we test whitespace tags here, which generates a test suite from this function, and tests against this Swagger document. If you can share a spec that reproduces an issue, I'll add it to this suite.

[pablocoberly]

Closing. My apologies. It has something to do with the environment we're deploying the bundle into.

[shockey]

Cool, glad you figured it out. If there's something we're not accommodating correctly on our end, please open a new issue and we'll see what we can do to support you!

[pablocoberly]

@shockey Finally, figured out this was related to doc expansion setting. Have updated the issue details.

[pablocoberly]

@shockey Can you check if this seems right to you?

[pablocoberly]

I used the following tests based on my understanding of how white space is handled when docExpansion is none, both of which fail:

    describe("Operation with whitespace in tag+id and `docExpansion: none` enabled", () => {
      it("should expand a tag", () => {
        cy.visit(`${swagger2BaseUrl}&docExpansion=none#/my%20Tag/`)
          .get(`.opblock-tag-section.is-open`)
          .should("have.length", 1)
      })
      it("should expand an operation", () => {
        cy.visit(`${swagger2BaseUrl}&docExpansion=none#/my%20Tag/my%20Operation`)
          .get(`.opblock.is-open`)
          .should("have.length", 1)
      })
    })

There is some funky stuff going on with double-encoding of url parameters.

Starting from http://localhost:3230/?deepLinking=true&url=/documents/features/deep-linking.swagger.yaml&docExpansion=none and opening the links to the "my Tag" tag, and the "my Operation" operation in new tabs:

Anchor	Expands Tag?	Expands Operation?
#/my%20Tag	FALSE	FALSE
#/my%2520Tag	TRUE	FALSE
#/my%20Tag/my%20Operation	FALSE	FALSE
#/my%2520Tag/my%2520Operation	TRUE	FALSE

Would really appreciate another set of eyes, as I can't pinpoint where this errant behaviour is originating. @shockey

[shockey]

@pablocoberly hmm, this definitely looks funky - thanks for the investigative work.

I'll dig into this next week and try to get some failing tests based on the anchors you laid out above!
