Why is it a must to use port 8080 for dfx nns install and/or how can I change it?

❯ dfx nns install

The constraint was part of a hacky starting point and hasn’t been removed. You can probably easily change it here

I don’t understand what you mean, how can I change it?

With a PR. I just assumed that that would be ‘easy’ for you :wink: I’ve asked around in the past and nobody really had a reason against lifting the restriction

Providing a PR is not on the agenda. Thanks for the feedback.

By the way, it’s probably more work than removing the limitation. The dapps (NNS dapp) that get installed through this dfx command should probably also inherit the port. I guess that’s why the limitation was introduced in the first place. Now I understand it better by reading the comment you pointed.

Anyway, I’m going to continue development while switching between ports. I probably won’t have to switch and use “dfx stop/start” too often.
