Ask HN: Best Way to Mock APIs in 2020?

I'm looking for a good way to Mock APIs for a sideproject, so far I haven't found any solution that has blown me away and I'm wondering If I'm missing anything.

I'm curious what people recommend for the best way to Mock APIs?

I was wondering if you had a chance to have a look at Microcks (https://microcks.io/) ?

Depends how advanced the mocking behaviour requirements are. For most projects, I find json-server sufficient.

Remember that perfect is the enemy of good enough. If you're looking to be blown away by your mock server you may never get round to building your product.

I would suggest having a look at Microcks (https://microcks.io) as a way to produce mocks from OpenAPI contracts, Postman collection or other assets...

Full disclosure : I am the founder of the project ;-)

I've found mitmproxy (https://mitmproxy.org) in reverse mode really useful. I'm a mobile dev and when the backend work is still pending I usually mock the backend requirements by selectively patching or adding endpoint support, it can be used like so:

    mitmproxy --mode reverse:https://my.privateapi.com -s ./path/to/mockscript.py

This allows me to implement most of the UI and server interactions w/o being blocked by server work.
