It is great help. Could you please provide guidance on how to simulate API requests using a syntax pattern similar to sample.com/api/*?
Mokku is an excellent lightweight mocking tool for FE development. I would like to leave one bug report - I would open on github but it seems as of Jan 2024 the repo is private(!). When developing a nextjs application, using query parameters and using the nextjs useRouter, navigating gets the following error: Failed to fetch RSC payload for http://localhost:3000/foo?query=bar. Falling back to browser navigation. TypeError: e.url.indexOf is not a function Error: e.url.indexOf is not a function at y (chrome-extension://somethingwrittenhere/js/inject.js:1:6216) // snip This is only an issue when mokku is enabled.
Love this extension! I wish there was a way to import/export the created mocks to a json file so my team could be kept in sync with the same mocks. Along with a direct import button to select the json file, an alternative option to import by providing a url to pull in this json file from a remote system.
Just Wow, super helpful and simple to use !
I uninstlled old version and installed 2.1 . Now Im getting blank , white screen in the devtolls from mokku
This tool is critical for mocking backend service responses during front end development. I especially like the Log feature that lets me capture real responses that I can then mock with one click.
Extension doesn't work and breaks sites such as youtube and google docs.
So glad I found this extension. It's going to be very useful to develop error-handling in my app, thanks.
Very useful tool, it will be better if this tool handle also GraphQL queries and mutations. Thanks a lot Mukul Jain !!
Was working beautifully. But stopped working since Version 112.0.5615.165 (as of April 27, 2023)
