How does axios determin the url?

Hi!

So just (I hope) a quick question since we are having an internal discussion about this but how does axios determine which url it should use?

We have a call that does this

axios.defaults.baseURL = /api/;


const patchApprove= (payload: Approve): Promise<any> => {
  const headers = {
    "Content-Type": "application/json",
  };
  return axios.patch("/order/approve/", payload, { headers });
};

and then a reverse proxy in our nginx configuration to route it correctly.

So since axios becomes XMLHttpRequests on the client machine it uses the default behavior of javascript which makes all requests starting with /api start at the base address of the homepage e.g

Request sent from https://axios-http.com/docs/intro with the path /api/test is transformed to https://axios-http.com/api/test

Any request made with api/ uses the current homepage address path execept current page e.g

Request sent from https://axios-http.com/docs/intro with the path api/test is transformed to https://axios-http.com/docs/api/test
