Authenticatornator

Authenticating

To authenticate users three steps are involved

• configuring the client: This consists of creating a new instance of authenticatornator, and passing it your oauth configuration, and if needed, options

• redirecting to the login url: This is done by generating a a url using .getLoginUrl(), which the client can then redirect to

• exchangingin the return url for a token: This can be done using the .exchangeUrl(url). This call will figure out it the response is an autorization code, which has to be exchanged to an access token, or if it simply is an access code

Example

import Auth from 'authenticatornator';
import config from './config';

const auth = new Auth(config);

const boot = async () => {
  const url = location.href;

  if (auth.isValidUrl(url)) {
    await auth.exchangeUrl(url);
  } else {
    const url = await auth.getLoginUrl();
    location.href = url;
  }
}

boot().catch(err => console.error);

Usage

const profile = await auth.getProfile();
const response = await auth.request({
  method: 'get',
  url: 'https://api.example.com/user',
});

To access to token for using in other environment, the token has to be set as exportable when creating the client

const auth = new Auth({
  ...config
}, {
  allowExport: true,
});

const token = await auth.getToken();

Saving and loading tokens

Since it is not recommmended to make tokens exportable, another method for saving and loading is required. This can be supplied as options to the auth client, by supplying a load and save function to the client

const auth = new Auth({
  ...config
}, {
  save: (value, { key }) => localStorage.setItem(key, value),
  load: ({ key }) => localStorage.getItem(key),
});

if (auth.load({ key: 'token' })) {
  const token = await auth.getToken();
} else {
  // No valid token stored, user login is required
  await auth.save({
    key: 'token',
  });
}

Adding platforms

By default this comes with three supportet platforms, node, browser and react-native, and will try to autoselect the right one for the current platform
