Thanks for pointing that out.
I’ve moved the description into the PR itself and removed the extra PR_DESCRIPTION.md file.

Did you perform some tests for this implementation ?

Yes, I performed local testing and also added automated tests.
- 7 new tests were added in
parseData.test.tscovering JSON, URL-encoded, text, heuristic detection, header priority, backward compatibility, and empty data handling. - All tests passed successfully (7/7).
- Build completed without errors.
Everything works as expected without regressions.

Hi @versona-tech thank you for your contribution, please check the comments on your PR. @forhad-hosain can you take some time to help in testing these changes and verify that they are not breaking for the UI ? |
- Add tests for explicit content-type headers (JSON, text) - Add tests for heuristic detection when no headers present - Add tests for backward compatibility with existing functionality - Mock dependencies to isolate parseData behavior - All 7 test cases passing successfully - Validates the content-type detection improvements in handleNone function Relates to SmythOS#154 Signed-off-by: versona-tech <your-email@example.com>

Hi @versona-tech
Thank you so much for your awesome contribution! 🎉 Your implementation looks great. There’s just a very small adjustment required to make it fully compatible with our UI.
Here’s an example of the config structure we receive from the UI:
config = {
"id": "<COMPONENT_ID>",
"name": "APICall",
"outputs": [...],
"inputs": [...],
"data": {
"method": "POST",
"url": "https://httpbin.org/post",
"headers": "{\n \"Content-Type\": \"multipart/form-data\"\n}",
"contentType": "none",
"body": "{\n \"file\": \"{{file}}\"\n}",
...
},
...
}
As you can see, both headers and body are always expected to be strings. So, could you please make sure to handle them accordingly?
This means:
You will receive config.data.headers as a string.
You need to parse it before using it in your implementation.
Once updated, please also adjust the test cases to reflect this behavior.
Thanks again for your great work! 🙌

@versona-tech Handling binary data is a bit tricky. By setting contentType to binary, we can simply call handleBinary().
But with contentType none, users might specify types like image/png, video/mp4, etc, in the headers.
We could check for common file types and call handleBinary() if there’s a match. What do you think?

@forhad-hosain this might be helpful, I recently migrated many unit-tests from our old repo. |

📝 Description
🚀 Improve Content-Type Detection in API Call Parser
📝 Description
This PR enhances the
handleNonefunction inparseData.tsto intelligently detect and handle different content types when none is explicitly specified. The improvement addresses a long-standing FIXME comment and significantly improves API reliability.🎯 What This Fixes
Before: The
handleNonefunction would simply return raw data without attempting to determine the appropriate content type, leading to potential parsing issues.After: The function now:
