  modules: [
    "@workmate/nuxt-auth"
  ],
  ...
});

Configure Auth

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ["@workmate/nuxt-auth"],
  auth: {
    providers: {
      local: {
        endpoints: {
          signIn: {
            path: "/signin",
            method: "POST",
            tokenKey: "token",
            body: {
              principal: "username",
              password: "password",
            },
          },
        },
      },

      github: {
        CLIENT_ID: process.env.GITHUB_CLIENT_ID || "",
        CLIENT_SECRET: process.env.GITHUB_CLIENT_SECRET || "",
        HASHING_SECRET: process.env.HASHING_SECRET || "secret",
        SCOPES: "user repo",
      }
    },
    global: false,
    redirects: {
      redirectIfNotLoggedIn: "/login",
      redirectIfLoggedIn: "/",
    },
    apiClient: {
      baseURL: "",
    },
    defaultProvider: "local",
    token: {
      type: "Bearer",
      maxAge: 1000 * 60 * 60 * 24 * 30,
      cookiesNames: {
        accessToken: "auth:token",
        refreshToken: "auth:refreshToken",
        authProvider: "auth:provider",
        tokenType: "auth:tokenType",
      },
    },
  },
});

While using github provider

If you are using the github provider, you would need to add the callback <baseUrl>/api/auth/callback/github to your github app settings.

Usage

composables

const { loggedIn,  user, token, refreshToken, login, logout, refreshUser, refreshTokens } = useAuth();

// state is of type AuthState
type AuthPlugin = {
  loggedIn: ComputedRef<boolean>;
  user: ComputedRef<any | null | undefined>;
  token: ComputedRef<string | undefined>;
  refreshToken: ComputedRef<string | undefined>;
  tokenType: ComputedRef<string | undefined>;
  provider: ComputedRef<string | undefined>;
  login: (
    provider: string | SupportedAuthProvider,
    data?: Record<string, string>,
    redirectTo?: string
  ) => Promise<
    | {
        tokens: AccessTokens;
      }
    | {
        message: string;
      }
  >;
  logout: (redirectTo?: string) => Promise<unknown>;
  refreshUser: () => Promise<void>;
  refreshTokens: () => Promise<void>;
};

To use useFetch with the authorization header, use useAuthFetch, and instead of using $fetch use $authFetch

useAuthFetch("/api/auth/melting", options);

// instead of $fetch,
$fetch("/api/auth/melting", options);

// use,
const { $authFetch } = useNuxtApp();
$authFetch("/api/auth/melting", options);

to change the base URI of the authFetch client, update the nuxt.config.ts

// nuxt.config.ts
export default defineNuxtConfig({
  auth: {
    ...
    apiClient: {
      baseURL: "http://localhost:8080/v1",
    },
    ...
  },
})

Logging in

const { login } = useAuth();

// to login
login("local", {
  principal,
  password,
});

// using github
login("github")

middlewares

Route middleware

To protect a page

// pages/index.vue
definePageMeta({
  middleware: "auth",
});

// or if adding it to a list of middlewares
definePageMeta({
  middleware: [..., "auth", ...],
});

To make sure a page is only accessible if you are not logged in. Eg. a login page

// pages/login.vue
definePageMeta({
  middleware: "auth-guest",
});

// or if adding it to a list of middlewares
definePageMeta({
  middleware: [..., "auth-guest", ...],
});

Global middleware

For a global middleware, set the the auth.global to true in the nuxt.config.ts file

export default defineNuxtConfig({
  ...
  auth: {
    global: true,
    ...
  },
})

To prevent a page from being protected from auth, set the auth meta to false

// pages/index.vue
definePageMeta({
  auth: false,
});

Example of nuxt.config.ts

const BACKEND_URL = "http://localhost:8080/api/v1";
export default defineNuxtConfig({
  modules: ['@workmate/nuxt-auth'],
  auth: {
    global: true,
    redirects: {
      redirectIfLoggedIn: "/protected",
    },
    apiClient: {
      baseURL: BACKEND_URL,
    },
    providers: {
      local: {
        endpoints: {
          user: {
            path: BACKEND_URL + "/api/auth/user",
            userKey: "user",
          },
          signIn: {
            path:  BACKEND_URL + "/api/auth/login/password",
            body: {
              principal: "email_address",
              password: "password",
            },
            tokenKey: "token",
            refreshTokenKey: "refresh_token",
          },
          refreshToken: {
            path: BACKEND_URL + "/api/auth/refresh",
            method: "POST",
            tokenKey: "token",
            refreshTokenKey: "refresh_token",
            body: {
              token: "token",
              refreshToken: "refresh_token",
            },
          }
        }
      },

      github: {
        CLIENT_ID: process.env.GITHUB_CLIENT_ID || "",
        CLIENT_SECRET: process.env.GITHUB_CLIENT_SECRET || "",
        HASHING_SECRET: process.env.HASHING_SECRET || "secret",
        SCOPES: "user repo",
      }
    }
