In this five-part tutorial series, you'll learn how to build a Zendesk Chat app from start to finish. The app you'll build is called Learn More. This tutorial covers the first steps to building the app:
The other tutorials in the series teach you how to build and install the app:
- Part 2 - Designing the user interface
- Part 3 - Creating and inserting templates
- Part 4 - Getting data
- Part 5 - Installing the app in Zendesk Chat
Because the tutorials build on each other, tackle them in order and finish each tutorial before moving on to the next one.
To download the completed source code of the app in this tutorial, click learn_more.zip. You can review the code as you follow along or check your work.
What you'll need
To build and upload a private app in Chat, you must have Zendesk Chat on the Professional or Enterprise plan. Your Chat account must also be linked to a Zendesk Support account.
Planning the app
You should have a good idea of how your app will look and work before you start working on it. The app you'll build in this tutorial is called Learn More and is designed to let a chat agent send a visitor links to more information about any subject. It'll have a simple interface consisting of a search box and button. Here's a mockup of the user interface:
The app will appear in the sidebar on the right side of the agent's chat interface.
The app should work as follows:
At any time during a chat, the agent enters a subject in the app's search box and clicks Search
The app makes an HTTP request to the MediaWiki API for the top 3 articles on Wikipedia about the subject
The app inserts links to the 3 articles directly in the chat's text area
The agent presses Enter to send the links to the visitor
Installing the Zendesk app tools
In this section, you'll install the Zendesk app tools (also known as ZAT). Among other tasks, the tools let you perform the following tasks:
- Automatically create all the necessary files and folders for a new app
- Test your app locally in a browser
- Validate your app
- Package your app for upload
Installing the tools is a one-time task. Once installed, you can use ZAT for all your Zendesk app projects.
Follow the instructions in Installing and using the Zendesk apps tools. After you're done, return here to continue the tutorial.
Creating the app files
After installing the Zendesk app tools, you're ready to start building the Chat app. The first step is to create the starter files for a new app called Learn More in a folder called learn_more.
Create the app files
- In your command-line interface (the command prompt in Windows or Terminal in Mac OS X), navigate to the folder where you want the app files to be saved in a subfolder.
Use the cd command (for change directory) to navigate to a child folder. Example:
$ cd projectsTip: To go back up to a parent directory, use cd followed by a space and two periods. Example:
- Run the following ZAT command:
$ zat new
If you get an error that the command doesn't exist, make sure the Zendesk app tools are installed. See Installing the Zendesk app tools.
- At the prompts, enter the following values:
- author's name - your name
- author's email - your email
- author's url - your website url if you have one, or press Enter to leave it blank
- app name - Learn More
- iFrame URI - press Enter to leave it blank. You'll use the default local iframe file
- directory name - learn_more
The ZAT tool creates and lists the directory and files. The window should look as follows in Mac OS X:
- Open your file browser and navigate to the files.
The folder contains an assets and translations folder, plus a manifest.json and README.md file. You can add as many files as you need when you're building your app, but for now it's all you need to start building an app.
Because it's an iframe app, you can host the app in Zendesk Chat or on a remote server with any technology stack you prefer. If you're only using client-side technologies like Handlebars and jQuery, as you will be here, you can simply host it in Zendesk Chat.
Everything is in place to start building. In the next tutorial, you'll learn more about the HTML file to be iframed into the chat window. You'll change the heading, add a footer, and add some styles to meet the design requirements specified in Planning the app above. Get started: Part 2 - Designing the user interface.
