The Dialogflow Console has a built-in code editor, called the
inline editor
that you can use to create fulfillment code and deploy the code to
Cloud Functions.
Cloud Functions has associated charges,
but the service is available for no charge up to a
significant number of monthly invocations. Note that you still
must register and provide a valid billing account. Cancel anytime.
When you initially enable the inline editor,
Node.js fulfillment code is pre-populated with default handlers for
default intents
that are included for all agents.
The code also has commented instructions
for adding handlers for developer-defined intents.
The inline editor is intended for simple fulfillment testing and prototyping.
Once you are ready to build a production application,
you should create a
webhook service.
Dialogflow fulfillment library
The inline editor uses the
Dialogflow fulfillment library
by default.
This library is no longer maintained,
but it remains useful as a simple fulfillment library solution.
This library should only be used by inline editor code.
The Dialogflow fulfillment library does not support
versioning.
If you need to use versioning,
choose one of the following options:
Overwrite the default inline editor code with your custom webhook code.
If you modify your code with the Cloud Functions console,
you can no longer use the inline editor to modify your code.
Your function will continue to provide fulfillment for your agent,
but future edits must be made in the Cloud Functions console.
The inline editor function must be named
dialogflowFirebaseFulfillment.
You cannot save or download code modified in the inline editor
without deploying it first.
The inline editor only supports two files:
index.js:
Contains all of your fulfillment code.
package.json:
Modifying this file will install any dependencies
you specify upon deployment.
See the Dialogflow fulfillment library section
for limitations of this library that is used by the inline editor by default.
