This is a preview of the next gen of this lib. Goal is that anyone can include this tiny lib and start building a UI for Home Assistant.

Changes:

  • Move bundler to microbundle
  • Drop support for API password
  • Add support for authorizing with an instance, fetching and refreshing tokens
  • Allow to pass in optional methods for saving/restoring tokens

to do:

  • break up subscribe config
  • typescript ?

Size:

Wrote 3.17 kB: haws.es.js
Wrote 3.16 kB: haws.js
Wrote 3.23 kB: haws.umd.js

Note: currently depends on a pending PR for Home Assistant that adds CORS to the /auth/token endpoint.

Example usage of this lib (also included as example.html to run locally):

This piece of code will:

  • Prompt user for the url of their Home Assistant instance
  • Redirect user to authorize url of instance and let user log in
  • Once logged in, will redirect user back to this page where tokens will be fetched and connection established
<html>
  <body>
    <script type='module'>
      import {
        getAuth,
        createConnection,
        subscribeEntities,
        ERR_HASS_HOST_REQUIRED,
      } from './dist/haws.es.js';

      (async () => {
        let auth;
        try {
          auth = await getAuth();
        } catch (err) {
          if (err === ERR_HASS_HOST_REQUIRED) {
            const hassUrl = prompt("What host to connect to?", "http://localhost:8123");
            auth = await getAuth({ hassUrl });
          } else {
            alert(`Unknown error: ${err}`);
            return;
          }
        }
        const connection = await createConnection(auth);
        subscribeEntities(connection, entities => console.log(entities));
      })();
    </script>
  </body>
</html>
