anchorGetting Started Guide

In this example, we'll use Node.js to create a simple project that will post a message to a room.

Overview

• Create a Webex space
• Post a Message

Requirements

• Node.js LTS 10.x and later, npm 6.x and later
• Optionally: nvm to manage Node.js versions

Step 1: Create the Project Directory

cd /my/project/directory
npm init

You’ll be prompted to answer a few simple questions, but typically the defaults are just fine.

Step 2: Install the JavaScript SDK

Now, install webex:

npm install --save webex

Step 3: Start Using the SDK

So, you want to send a message. For demonstration purposes, we’ll use environment variables to authorize the SDK with your personal access token. If you're logged into this site, you can find your token in Getting Started. This token provides access to your account for testing purposes, and shouldn't be used for anything other than testing. If you don't already have a Webex account, click Sign Up at the top of this page to create a new account.

Create a new file in your project directory named index.js and add the following to it:

var webex = require('webex/env');
webex.rooms.create({
  title: 'My First Room!'
})
  // Make sure to log errors in case something goes wrong.
  .catch(function(reason) {
    console.error(reason);
    process.exit(1);
  });

Now, open the Webex Web Client to you see your code in action. Then, back in your terminal, run the following command:

WEBEX_ACCESS_TOKEN=$YOUR_TOKEN_FROM_THE_PORTAL node index.js

Check out the web client. You should see your new room. Now, let’s send a message to it.

Open up index.js again and replace its contents with the following code:

var webex = require('webex/env');
webex.rooms.list({
  max: 10
})
  .then(function(rooms) {
  var room = rooms.items.filter(function (room) {
    return room.title === 'My First Room!';
  })[0];

  return webex.messages.create({
    text: 'Hello World!',
    roomId: room.id
  });
})
// Make sure to log errors in case something goes wrong.
.catch(function(reason) {
  console.error(reason);
  process.exit(1);
});

Run it again with the following:

WEBEX_ACCESS_TOKEN=$YOUR_TOKEN_FROM_THE_PORTAL node index.js

Now check out the web client. Congrats! You’ve sent your first message!

anchorTroubleshooting the Node.js SDK

If you're having trouble with the Node.js SDK, here's some more information to help troubleshoot the issue.

SDK Requirements

Review the following SDK requirements to make sure you're using the correct minimum versions of Node.js, npm, etc.:

• Node.js LTS 10.x and later
• npm 6.x and later
• Optionally: nvm to manage Node.js versions
• A Webex account and an integration with the necessary scopes

Additional Logging

You can add additional logging to your application to help narrow down any issues with the SDK.

Change the Log Level via an Environment Variable

You can change the log level via the WEBEX_LOG_LEVEL environment variable. For example, if you start your application server via npm serve, you'd set the variable before running your application to see increased logging:

WEBEX_LOG_LEVEL=info npm serve

While developing your application, you can set the WEBEX_LOG_LEVEL environment variable to debug see even more logging. For example, if you start your application server via npm serve-dev, you'd set the variable before running your application to see increased logging:

WEBEX_LOG_LEVEL=debug npm serve-dev

Firewall Ports

The Node.js SDK makes use of several network protocols and ports. If you're encountering connection or connectivity issues, make sure there aren't any firewalls blocking or preventing communication with any Webex endpoints. For more information about the network and web security requirements for Webex services, please see Network Requirements for Webex Services.

Getting Support

If you're stumped, contact the Webex Developer Support team for more help with the SDK.
