The jsforce library provides Node.js developers the ability to create apps that interact with the Salesforce API. The standalone examples provide good basic usage for the library. Join us as we take it to the next level and show how to use the library in large, complex, real-world applications. We'll cover patterns and practices for using jsForce in production. We will also explain how to organize your code for optimal reuse and maintainability. We will dig into using promises with jsForce for cleaner code. This presentation will be heavy on code examples and real world practices for large enterprise node applications.

What will we be discussing?
Outline

5. ​ $ npm install jsforce
​ Used as a node module in
server side JavaScript code.
​ Authenticate using OAuth2 or
with hard coded credentials.
​ $ npm install -g jsforce
​ Used to directly interact with
the library on the command
line.
​ Great for quickly interacting
with SF.com in code.
​ Authenticate interactively using
username/password.
​ Script tag in the html header
​
Most valid use case is in a
Canvas application.
​ All interaction with SF.com
directly in the browser.
Node Module Command Line Web Browser

​ Command Line Demo

7. ​ Client side
​ Angular
​ Sass
​ Angular ui-router
​ Server side
​ Node
​ Express
​ jsForce
​ Bluebird
Salesforce Explorer
​ https://github.com/gbockus/jsForceInAction

8. Salesforce Explorer Demo
​ Demo in the browser

9. ​ Built Using:
• Yeoman
• Angular full stack Generator
​ Features:
• Authenticate with Salesforce.
• View/Search all object types in
organization.
• See attributes for each object type.
• See recently updated objects of the
selected type.
Salesforce Explorer
​ How did it get started?

10. • Separate web tier from business logic
• Drive authentication scheme through configuration
• Use a build tool
• Promises make logic simpler to understand asynchronous flow
• Use the same Promise module across the application
• Test your code
Code organization and beyond
Best Practices

11. • Provides common Promise behavior
• Enabled use by getting developers familiar with utility Promise functions that are available
• Results in similarly organized code throughout application
Ok, mostly the bluebird Promise module in this example.
Third Party module Integration

12. • At minimum unit test code to verify functionality and provided example usage.
• Don’t interact with third parties (like Salesforce) in unit test.
• Use Mock objects: Node is great at this
• Useful libraries: Chai, Sinon
• Test Framework: Mocha
Do it!
Testing

13. Salesforce Service Test Demo
​ Show the tests being executed in both intellij and on the command line
​ Show the test file
​ Discuss how to mock jsForce functions
• Top Level (like auth)
• Second Level (like conn.sobject)
