I've installed the plugin and enabled it but i can't seem to mock my apis on http://localhost:3000
Machaenge 🤘🏻
I was waiting for a tool like this, and FINALLY - here is it! I can really mock an entire backend (without actual code for it) and make my front end work properly.
Indeed a useful tool to test the edge cases and reduce the dependency on dev team to test out negative scenarios on the browser. However I saw an issue in the logs page when I was making a multipart-form request, there it seems the tool is not capturing the request body. Thanks for developing this.
Very helpful for development
I've got this error every single page that I tried "Mokku not available on this url." I'm trying to use on my http://localhost as well.
Это просто офигенный инструмент! Спасибо разработчикам!
Very useful tool for testing
Great tool, exactly what I needed and actually works as opposed to many similar extensions.
Greatest tool ever for mocking API. Add a better JSON editor + linter... and it will definitively perfect !!!!
