AD Dialogflow Gateway by Ushakov (Hosted) is the quickest way to get started with Dialogflow for Web v2

You can use git or download from GitHub

Open the cloned folder. Then, using your favorite package manager get the dependencies

Using npm

npm i

Using yarn

yarn

Open config.js and change the gateway variable to your Dialogflow Gateway URL

Hint: the URL for Dialogflow Gateway Hosted by Ushakov is always your google cloud project id + .gateway.dialogflow.cloud.ushakov.co. If you have any troubles, make sure you connected your Agent to the Gateway, then visit the console, click on "Manage" and copy the Gateway URL

Example

export default {
    app: {
        gateway: "https://dialogflow-web-v2.gateway.dialogflow.cloud.ushakov.co"
        [...]
    }
}

[...]

The logo, agent name, description and available languages are fetched from Dialogflow. Change them in Dialogflow and it will sync to the UI. Please note, when adding new languages, you may have to translate some of the UI as well (i18n field in config.js)

Open your cloned folder. Then, using your favorite package manager run the serve command

Using npm

npm run serve

Using yarn

yarn serve

Your default browser should open and redirect to localhost:8080. If the port 8080 is already in use, you can give a port argument to connect at specified port

Using npm

npm run serve --port 9090

Using yarn

yarn serve --port 9090

PLEASE DO NOT USE THE DEVELOPMENT SERVER TO SERVE YOUR APP FOR VISITORS, DEVELOPMENT SERVER IS MEANT FOR THE DEVELOPMENT. PLEASE UPLOAD BUILD ARTIFACTS TO A STATIC WEB-SERVER

You can make a custom theme for Dialogflow for Web v2, according to the specification:

To apply the variables, open src/components/App/Theme.sass and change them in the \:root selector

You can also optimize your theme for Dark-mode-enabled clients within the same file and selector under the @media (prefers-color-scheme: dark)

Your app will be bundled to the dist directory

To build it you can use npm or yarn

Using npm

npm run build

Using yarn

yarn build
