                         --credentials devicecredentials.json \

t GoogleAssistant = require('./googleassistant');
t deviceCredentials = require('./devicecredentials.json');

t CREDENTIALS = {
ient_id: deviceCredentials.client_id,
ient_secret: deviceCredentials.client_secret,
fresh_token: deviceCredentials.refresh_token,
pe: "authorized_user"


t assistant = new GoogleAssistant(CREDENTIALS);

Usage

The GoogleAssistant class has several methods and helpers.

• .assist(string) - Sends a string request to the Assistant. Returns a promise with the text response or device action if applicable.
• .setDeviceConfig(modelid, instanceid) - Sets the device model and instance. This will need to be set with the model id you defined in the Actions Console to use device actions.
• .startConversation([initialPrompt]) - Starts a conversation with “my test app”. Returns a promise with the text response.
• .startConversationWith(appName, [initialPrompt]) - Starts a conversation with an Assistant app. Returns a promise with the text response.
• .endConversation() - Ends a conversation with an Assistant app. Returns a promise.
• .setLocale(locale) - Changes the Assistant locale, in the format en-US.

stant.assist('what time is it')
hen(({ text }) => {
console.log(text); // Will log "It's 12:30"
;

You can chain together several requests and responses with Promises, as shown below.

stant.assist('what is the weather')
hen(({ text }) => {
console.log(text);
return assistant.assist('what about the weather tomorrow')

hen(({ text }) => {
console.log(text);
;
