Dialog Node.js

The Dialog starter application in Node.js is a sample that demonstrates how the IBM Watson Dialog service works in a specific context.

**This application requires a dialog file to be preloaded. You can use the** [dialog-tool](https://github.com/watson-developer-cloud/dialog-tool) **to create a dialog.**

Give it a try! Click the button below to fork into IBM DevOps Services and deploy your own copy of this application on Bluemix.

Getting started

1. Create a Bluemix account. Sign up in Bluemix or use an existing account. Watson services in beta are free to use.

2. Download and install the Cloud-foundry CLI tool.

3. Edit the manifest.yml file and replace <application-name> with a unique name for your copy of the application. The name that you specify determines the application's URL, such as <application-name>.mybluemix.net.

```none
applications:
- services:
  - dialog-service-beta
  name: <application-name>
  command: node app.js
  path: .
  memory: 256M
```

4. Connect to Bluemix by running the following commands in the command-line tool:

```sh
$ cf api https://api.ng.bluemix.net
$ cf login -u <your-Bluemix-ID>
```

5. Create the Dialog service in Bluemix by running the following command:

```sh
$ cf create-service dialog beta dialog-service-beta
```

6. Push it live by running the following command:

```sh
$ cf push
```

6. Add your DIALOG_ID and restage the app:

```sh
$ cf se <application-name> DIALOG_ID <dialog-id>
$ cf restage <application-name>
```

If you don't have a dialog_id you can create one using the dialog-tool

Running the application locally

The application uses Node.js and npm, so you must download and install them as part of the following steps.

1. Copy the username, password, and url credentials from your dialog-service service in Bluemix to app.js. To see the credentials, run the following command, where <application-name> is the unique name you specified:

```sh
$ cf env <application-name>
```

The following example shows credentials for the Dialog service:

```sh
System-Provided:
{
"VCAP_SERVICES": {
  "dialog": [{
      "credentials": {
        "url": "<url>",
        "password": "<password>",
        "username": "<username>"
      },
    "label": "dialog",
    "name": "dialog-service-beta",
    "plan": "beta"
 }]
}
}
```

2. Install Node.js.
3. Go to the project folder in a terminal and run the npm install command.
4. Start the application by running node app.js.
5. Open http://localhost:3000 to see the running application.

Troubleshooting

To troubleshoot your Bluemix app the main useful source of information are the logs, to see them, run:

$ cf logs <application-name> --recent
