Set Session ID Cookie in Nuxt Auth

This is how I handled this, which came from a forum post that I cannot find since. First get rid of nuxt/auth and roll your own with vuex store. You will want two middleware, one to apply to pages you want auth on, and another for the opposite.

This assumes you have a profile route and a login route that returns a user json on successful login.

I'm also writing the user to a cookie called authUser, but that was just for debugging and can be removed if you don't need it.

export default {
  state,
  getters,
  mutations,

store/state

export default () => ({
  user: null,
  isAuthenticated: false,
});

store/actions

export async function nuxtServerInit({ commit }, { _req, res }) {
  await this.$axios
    .$get("/api/users/profile")
    .then((response) => {
      commit("setUser", response);
      commit("setAuthenticated", true);
    })
    .catch((error) => {
      commit("setErrors", [error]); // not covered in this demo
      commit("setUser", null);
      commit("setAuthenticated", false);
      res.setHeader("Set-Cookie", [
        `session=false; expires=Thu, 01 Jan 1970 00:00:00 GMT`,
        `authUser=false; expires=Thu, 01 Jan 1970 00:00:00 GMT`,
      ]);
    });
}

store/mutations

export const setUser = (state, payload) => (state.user = payload);
export const setAuthenticated = (state, payload) =>
  (state.isAuthenticated = payload);

store/getters

export const getUser = (state) => state.user;
export const isAuthenticated = (state) => state.isAuthenticated;

middleware/redirectIfNoUser

export default function ({ app, redirect, _route, _req }) {
  if (!app.store.state.user || !app.store.state.isAuthenticated) {
    return redirect("/auth/login");
  }
}

middleware/redirectIfUser

export default function ({ app, redirect, _req }) {
  if (app.store.state.user) {
    if (app.store.state.user.roles.includes("customer")) {
      return redirect({
        name: "panel",

  }
}

pages/login- login method

async userLogin() {
  if (this.form.username !== "" && this.form.password !== "") {
    await this.$axios
      .post("/api/auth/login", this.form)
      .then((response) => {
        this.$store.commit("setUser", response.data);
        this.$store.commit("setAuthenticated", true);
        this.$cookies.set("authUser", JSON.stringify(response.data), {
          maxAge: 60 * 60 * 24 * 7,
        });
        if (this.$route.query.redirect) {
          this.$router.push(this.$route.query.redirect);
        }
        this.$router.push("/panel");
      })
      .catch((e) => {
        this.$toast
          .error("Error logging in", { icon: "error" })
          .goAway(800);
