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 package manager install the dependencies
Using npm
npm i
Using yarn
yarn
Open src/config/index.js and change the endpoint variable to your Dialogflow Gateway URL
Hint: the URL for Dialogflow Gateway Hosted by Ushakov is always your google cloud project id + .core.ushaflow.io. 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 {
endpoint: 'https://dialogflow-web-v2.core.ushaflow.io'
[...]
}
[...]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 (translations.json in src/translations)
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
