Dialogflow Gateway enables third-party integrations like this one to securely access the Dialogflow V2 API
You can use git or download it directly from github
Open the cloned folder. Then, using your favorite package manager get the dependencies
Using npm
npm install
Using yarn
yarn
Open config.js and change the gateway variable to your Dialogflow Gateway URL. If you don't know, what Dialogflow Gateway is, please read the docs one more time, because you have missed something out
Hint: the URL for Dialogflow Gateway Hosted by Ushakov is always your google cloud project id + .gateway.dialogflow.cloud.ushakov.co. If you have 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 the available languages are fetched from Dialogflow directly. Change them in Dialogflow and it will be synced 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). Also don't forget to clean your cache, if you make changes to the Agent
Open your cloned folder. Then, using your favorite package manager run dev command
Using npm
npm run dev
Using yarn
yarn dev
When you done these steps, your default browser should open and redirect you to localhost:8080. If the port 8080 is already in use, you can give an port argument to connect at specified port
Using npm
npm run dev --port 9090
Using yarn
yarn dev --port 9090
PLEASE DO NOT USE THE DEVELOPMENT SERVER FOR SERVING YOUR APP IN PRODUCTION, DEVELOPMENT SERVER IS MEANT FOR THE DEVELOPMENT. INSTEAD 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 dist/build.js
To build it you can use npm or yarn
Using npm
npm run build
Using yarn
yarn build
- Q: I changed the gateway url, but the responses are the same as with the previous one
- A: Make sure you have cleaned your cache and rebuilt your app. In Safari go to "Develop" > "Empty Caches". In Chrome: "Developer Tools" > "Application" > "Clear storage" > "Clear site data"
