Update set up configuration page to v2 Standards about redux-json-api

[egeriis]

Let's get a PR 🎉

[Nopzen]

Ill try to get to it tonight, some RL stuff came in the way.

Scratch that, ill have a look in the weekend.

[egeriis]

@Nopzen Had a chance to look at this?

[Nopzen]

@egeriis Sorry no. I'll try to take a look asap, i got to open some codebase today where i use this.

[Nopzen]

@egeriis so i can see i just use a very basic example:

store.dispatch(setAxiosConfig({
    baseURL: 'http://localhost:3000/'
}));

And as i can see out of the code here:
https://github.com/redux-json-api/redux-json-api/blob/master/src/jsonapi.js#L194

[API_SET_AXIOS_CONFIG]: (state, { payload: axiosConfig }) => {
    return imm(state).set(['endpoint', 'axiosConfig'], axiosConfig).value();
  },

We are basically on the key endpoint setting the given Axios config given as param to the action.

My assumtion here is we can pass a config as the given example of the Axios repo: https://github.com/axios/axios#axioscreateconfig? So supporting: baseurl, timeout & headers?

Also i wonder why is it stored on a key called endpoint should it not just be axiosConfig ??

[egeriis]

Yeah, the configuration you provide are directly proxied to axios.

Also i wonder why is it stored on a key called endpoint should it not just be axiosConfig ??

Legacy. We used to have endpoint and base path specified here. Feel free to move it. Should not break anything.

[egeriis]

I think I just discovered that we haven't documented the new resolve value from readEndpoint, i.e. that it now returns an ApiResponse instance.

[Nopzen]

So okay I'am back on track now.

So i, working on this PR again and for now i will update the documentation on how to get going, and setting up the axios config.

And on this comment form @egeriis

Legacy. We used to have endpoint and base path specified here. Feel free to move it. Should not break anything.

I investigated it broke a lot by removing the endpoints key, i expected this, but I've refactored it to a working state again, and are no building tests for this use case, meanwhile i explored this refactor i discovered we didn't have test cases for the redux-thunk actions, these are the one i will create a bare minimum test cases that covers my refactor.

The test setup will include as of now installation of package Chai, and moxios (mocking axios), i hope to have a pr soon.

Sorry for the delay of things.
