GAS-S: Google Assistant Server Starter

A Node.js server for your Google Assistant (and Google Home).

Action Manifest (action.json)

{
    "versionLabel": "1.0.0",
    "agentInfo": {
        "languageCode": "en-US",
        "projectId": "my first action",
        "voiceName": "female_2"
    },
    "actions": [{
        "initialTrigger": {
            "intent": "assistant.intent.action.MAIN"
        },
        "httpExecution": {
            "url": "<PUBLIC URL>"
        }
    }]
}

NOTE: if you're deploying your action on Google Cloud, use your Google Cloud Project ID instead of "my first action".

Package.json

In the package.json, we provide you with the following (handy) scripts:

{
    "scripts": {
        "start": "npm run server",
        "server": "nodemon dist/action.js",
        "ngrok": "ngrok http 8080",
        "build": "babel lib -d dist",
        "build:watch": "npm run build -- -w",
        "action:simulate": "gactions --verbose simulate",
        "action:preview": "node ./scripts/preview_action.js",
        "action:config": "node ./scripts/update_action_config.js",
        "action:autopreview": "npm run action:config && npm run action:preview",
        "action:deploy": "echo 'coming soon'",
        "release": "npm run build && npm version patch && git push --tags && git push && npm publish"
    }
}

NOTE: The default port used by GAS is 8080. See API section.

Tools bunlded by GAS for devs needs:

gactions: is the command line interface that you use to preview, simulate, and publish an action package. If you encouter errors with the bundled binary, use the gactions from the official website. GAS includes this just for convenience.
nodemon: Monitor for any changes in your node.js application and automatically restart the server.
ngrok: Introspected tunnels to localhost. Allows Google's server to access your local action (while in dev mode)

Step by Step

run npm install to install all deps
run npm start
run npm run ngrok and keep it running in the background,
run npm run action:autopreview, and follow the instructions on the terminal,
run npm run action:simulate to start the simulator in CLI mode (or use Google Home)
type in talk to my first action or start my first action

HINT #1: you can run npm run build:watch in order to watch and rebuild your files on the fly while you're working on your action.

HINT #2: I you have a Google Home device, you can use it instead of using the simulator.

NOTE: If you already have a dev server where you can host your this project, you can use your own URL in httpExecution.url and skip steps 1 and 2. And run npm run action:preview instead. See package.json for more details.

GAS API

See the GAS documentation from more details.

Deep Link invocation

In order to make a deep link invocation, you have to provide two things:

an invocation query in your action.json (see this example)
an intent (and its implementation here and here) that will be triggered when your action will be launched with the invocation query.

Then you just have to start your action like so:

talk to my first action to <ONE OF THE DEEP LINK QUERIES HERE>

For instance:

talk to my first action to know what is the date
