This SDK is the main developer resource for Oracle Digital Asistant integrations in a Node.js express environment. It provides two primary solutions for custom implementations against the Digital Assistant platform:
- Creating Custom Component Services
- Creating Webhooks
To install the SDK globally:
npm install -g @oracle/bots-node-sdk
To install the SDK locally in your current directory:
npm install @oracle/bots-node-sdk
When installed locally, use npx @oracle/bots-node-sdk instead of just bots-node-sdk to run the command-line interface (CLI) commands described in the Getting Started section.
This section explains the basic CLI commands to get your component service up and running. See the CLI documentation for a complete list of all the arguments and options that you can configure with each command.
Use the init command to create a component service package. For example:
bots-node-sdk init PizzaService --name pizza-service
This example creates a component service named pizza-service in a directory named PizzaService.
The component service includes one sample custom component named helloWorld.
You use the init component <name> custom command to add a component to an existing package. For example:
bots-node-sdk init component myCustomComponent custom
This example creates a component of type custom named myCustomComponent. Instead of typing custom for the component type argument, you can type c as a shortcut.
You use the init component <name> entityEventHandler command to add an event handler to an existing package. For example:
bots-node-sdk init component myEventHandler entityEventHandler
This example creates a handler of type entityEventHandler that is named myEventHandler. Instead of typing entityEventHandler for the component type argument, you can type e as a shortcut.
You use the init component <name> sqlQueryEventHandler command to add an event handler to an existing package. For example:
bots-node-sdk init component myEventHandler sqlQueryEventHandler
This example creates a handler of type sqlQueryEventHandler that is named myEventHandler. Instead of typing sqlQueryEventHandler for the component type argument, you can type s as a shortcut.
You use the init component <name> llmTransformation command to add an event handler to an existing package. For example:
bots-node-sdk init component myEventHandler llmTransformation
This example creates a handler of type LlmTransformation that is named myEventHandler. Instead of typing llmTransformation for the component type argument, you can type t as a shortcut.
You use the init component <name> llm command to add the event handler to an existing package. For example:
bots-node-sdk init component myEventHandler llm
This example creates a handler of type LlmComponent that is named myEventHandler. Instead of typing llm for the component type argument, you can type l as a shortcut.
To package the components, use the pack command. For example:
bots-node-sdk pack
This creates a component service package .tgz file that can be hosted as an express service, uploaded to a skill's embedded container in Digital Assistant, or uploaded to Oracle Mobile Hub.
To start a service on a local node server and host the custom component package, use the start command.
npm start
This example creates a component service running on a local node server. It uses the @oracle/bots-node-sdk dev dependency.
Alternatively, you can use this bots-node-sdk command to start the service. This command uses the global bots-node-sdk installation.
bots-node-sdk service
To see the metadata for all deployed components, run this cURL command:
curl -X GET localhost:3000/components
To deploy to a docker container, you can use the following commands:
npm run-script docker-build
docker-compose up
The SDK has full support for TypeScript. If you want to use TypeScript to write your custom components and event handlers, all you need to do is specify the language option when you create the component service. For example:
bots-node-sdk init MyComponentService --language typescript
or the shorter format:
bots-node-sdk init MyComponentService -l t
This example creates a TypeScript project in the MyComponentService directory.
If you subsequently use the init component command to add a component to a TypeScript project, it creates a TypeScript component instead of a JavaScript component.
When run on a TypeScript project, the service and pack commands transpile all files under the src directory into JavaScript files in the build directory.
The benefit of using TypeScript over JavaScript is that it is strongly typed, so, if you use an editor like Visual Code Studio, you'll get code completion features and compile-time type checking similar to Java.
See the README.md that's created in your scaffolded TypeScript project for more information.
