Getting session token in axios intercept

I’m using Axios this way:

const axios = userLoggedInAxios(app);

axios('url', {/* your options */}

This has identical behavior as userLoggedInFetch, showcased in shopify-app-template-node

Here the required module:

/**
 * Adds Shopifys Authorization Header to Axios requests through the use of a request interceptor
 *  app Shopify app instance
 * @returns AxiosInstance
 */
function authenticatedAxios(app) {
  const axiosShopify = axios.create();
  axiosShopify.interceptors.request.use((config) =>
    getSessionToken(app) // requires a Shopify App Bridge instance
      .then((token) => {
        // Append your request headers with an authenticated token
        config.headers["Authorization"] = `Bearer ${token}`;
        return config;
      })
  );
  return axiosShopify;
}

/**
 * Assures that Shopify Request is made for a logged-in user through the use of a response interceptor
 * It uses Shopifys redirect mechanism to redirect unauthenticated user-requests to the '/auth' endpoint
 *  app Shopify app instance
 * @returns AxiosInstance
 */
export function userLoggedInAxios(app) {
  const authAxios = authenticatedAxios(app);
  authAxios.interceptors.response.use((response) => {
    if (
      response.headers.get("X-Shopify-API-Request-Failure-Reauthorize") === "1"
    ) {
      const authUrlHeader = response.headers.get(
        "X-Shopify-API-Request-Failure-Reauthorize-Url"
      );

      const redirect = Redirect.create(app);
      redirect.dispatch(Redirect.Action.APP, authUrlHeader || "/auth");
      return null;
    }
    return response;
  });
  return authAxios;
}
