Displaying line breaks in the response text

Question

I use Swagger UI v2.2.0. I have a RESTful method which returns plain text. I want to display this text with line breaks.

At the moment, the returned text contains new li

Not sure if it helps, but I also faced the same issue.

I wanted to execute the following code in nodejs server:

app.post('/xyz', function (req, res) {
    res.status(400).send("MyError\nMyErrorStack:\nStackLine1\nStackline2")

}

and wanted output like:

"MyError
MyErrorStack:
StackLine1
Stackline2"

but got :

"MyError\nMyErrorStack:\nStackLine1\nStackline2"

so instead i split the string into array as shown used following:

err.error = errObj.stack.split("\n")

app.post('/xyz', function (req, res) {
    res.status(400).send(err)

}

and this printed

"Error": {    
    "error": [
      "Error: ENOENT: no such file or directory, open 'c:\\....'",
      "    at Error (native)",
      "    at Object.fs.openSync (fs.js:584:18)",
      "    at Object.fs.writeFileSync (fs.js:1224:33)",
      "    at Object.fs.appendFileSync (fs.js:1283:6)",
      "    at ...",
      "    at ...",
      "    at ...",
      "    at ...",
      "    at ...",
      "    at ..."
    ]
}

This worked for me.

This is currently not possible due to a documented bug in Swagger UI. Reference:

Inconsistent Markdown Newlines #2981

Bug in Model (Definition) Description with newline characters #3078

The second Issue listed, #3078 contains some discussion on overriding the styles used to render that part of the UI, but results appear inconsistent.

Note: I have subscribed to those issues and will update the answer and/or flag to close as no longer relevant when it is resolved.
