To simplify some aspects of oauth (especially token management), barista provides a simplified interface through the oauth package.

For Modules

Before Stream(), usually during construction, a module should Register an oauth2 configuration, and save the resulting value.

config, _ := google.ConfigFromJSON([]byte(/* json */), /* scopes */)
clientConfig = baristaOauth.Register(config)

Later, during Stream, an http client configured to use the saved oauth token can be obtained using Client()

client := clientConfig.Client()
for {
	resp, err := client.Do(/* request */)
	if sink.Error(err) {

Constructing the client in Stream also means that if the token is invalid, the user can go through the interactive flow and simply click to restart the module, which will pick up the newly saved token.

For Users

IMPORTANT: Oauth tokens are very sensitive. Barista makes every effort to ensure that the tokens are secured, by encrypting each token with a uniquely salted PBKDF2 derived key. However it still needs a master encryption key from which all other keys are derived, which can be considerd a password of sorts.

The key can be set using SetEncryptionKey([]byte). The recommended way to do this is to create a random key (using rand.Read), and storing the generated key for re-use using libsecret or equivalent.

Directly calling SetEncryptionKey([]byte("password")) is highly discouraged.

To save oauth tokens for all modules configured in a bar instance, simply run the binary from the command line with the argument setup-oauth

~/bin/mybar setup-oauth

Tokens are saved in ~/.config/barista/oauth (or $XDG_CONFIG_HOME/barista/oauth), so if you encounter any trouble with a specific provider, you can simply delete associated files and re-run the oauth setup.
