Salesforce Integration with Nodejs based applications using Canvas

Salesforce Canvas Integration

Salesforce provides many ways to integrate with external systems like SOAP, Rest, Bulk API, User Interface API and so on. One of useful way to integrate any existing web applications with Salesforce is using Canvas.

For sake of this post, I’m using Nodejs application and complete source code can be found here , on my Github repository. It can be deployed on Heroku easily, however I used my local computer to run canvas. That also proves point that integration is happening via Browser and therefore canvas application can be hosted on premise and not necessarily on DMZ layer.

Step 1 : Create Connected App in Salesforce

Enable OAuth in Connected app and provide any Callback URL. Canvas app does not use callback URL however we DO NEED scope.

Next step would be enabling canvas app itself connected app along with locations where we would be using it.

Video – Large Data Volume – How Lightning Platform Query Optimizer Works

Last year I presented how Query Optimizer works in Kitchner developer group. Found myself coming back to slide multiple times, so thought its good idea to post all information in this post.

Salesforce Single Sign On (SSO) using Janrain – Video

Janrain Salesforce Single Sign On Execution Flow

Salesforce supports many Auth Provider out of the box, which can be used as Identity provider. Some of the examples – Facebook, Google, Github, Salesforce, OpenId Connect , Linked In and Janrain.

If you are in need to use Wechat , Yahoo or some other social account like Microsoft, don’t get disappointed. Even if they are not available out of the box as Auth Provider in Salesforce , Salesforce has provided magical box Janrain. Janrain supports vast list of social platform which can be used as Identity provider for your Salesforce instance.

How Janrain is different compared to other SSO solutions for Salesforce

If we configure Identity provider for Salesforce using Single Sign On or Auth Provider, those options will appear on Login Salesforce page as a button (shown in below image).

Salesforce Integration with SQL Server Integration Services

On April-14, 2018, I had a chance to conduct online session on demonstrating integration between SQL Server Integration Services (SSIS) and Salesforce with the help of COZYROC connector.

This session covered below topics

Introduction to ETL
What is SQL Server Integration Services (SSIS)
COZYROC connector
Demo of extracting and updating records in Salesforce
Demo of downloading attachments from Salesforce
Demo of uploading attachments in Salesforce
Best Practices – How to configure SSIS package to avoid hardcoding
Best Practices – enabling logging

Video – Use Microsoft Azure’s Active Directory as Identity Provider for Salesforce SSO in 15 Minutes

Salesforce Azure SSO in 15 minutes

This is quick video tutorial on how Microsoft Azure can be used to setup as Identity Provider for Salesforce Single Sign On.

Few things worth of note:

If you are new to Microsoft Azure, you can get free trial access however you might need to provide Credit card details to use few features. You would not get charged because we get $200 worth credit for new Account that can be used in a span of year.
I was not able to use Azure’s Active Directory SSO for Just in Time (JIT) provisioning. Rather, it connects to Salesforce and creates user whenever user is provisioned in Active Directory, just like Identity Connect
Security token is mandatory. In case if you have IP login range then we don’t get Security token. To fix this, we can divide our password to have some value in Security token. As final password anyways is Password + Security Token. Shown in below image
When we assign any user to Enterprise application (in our case its Salesforce), we need to map profile to the user.

Introduction to Lightning Test Services with Jasmine

Lightning Testing Service (LTS)

In previous post, we discussed what is Jasmine and simple hello world program to see how it works. In this blog post, we will discuss how Jasmine can be used in Salesforce to test Lightning Component’s Javascript code.

Note : Everything we are discussing here is completely covered as part of Live coding in Apex Salesforce Saturday organized by Amit. Would like to thank Mohith for his support and answers during the demo. It also shows How SalesforceDX can be used daily by developers to perform development.

Jasmine and Mocha support is provided as a part of Lightning Test Service (LTS) by Salesforce. Jasmine and Mocha, both are well known and industry wide solution accepted in Javascript world. of course, Salesforce don’t want to stay behind in terms of its offering to developers thats why we have new baby in town – Lightning Test Service (LTS).

Getting Started with Jasmine Test Framework

Jasmine Testing Framework - Behavior Drive Development

Jasmine is a Javascript Testing framework which starts with behavioral specifications as a basis for writing test cases. To put it another way, you can consider user stories as a reference for write test cases. Each user story in your project can have one or more Jasmine test cases.

Majorly, Jasmine is made up of three functions

describe
it
assertions (expect)

Like standard frameworks, it also has setup method and tear down methods

beforeEach() – Setup Method
afterEach() – Teardown Method

For the sake of simplicity of post, I would not discuss much in detail. However, you can navigate to official Jasmine guide for deep dive.

Using JWT Flow to Authenticate Nodejs application with Salesforce

JWT OAuth

JWT OAuth uses digital signature to authenticate external application with Salesforce. JWT can be used to request an OAuth access token from Salesforce when a client wants to use a previous authorization.

Complete Source code is available here.

How JWT OAuth works

Developer creates a connected app and provides digital certificate in OAuth settings. You can refer this post to understand how openssl can be used to create digital certificate locally.
We need to make sure this connected app is already pre – approved either by using WebServer, User Agent or any other flow. You can find this step in video recorded.
We need to generate JWT token and sign it with certificate. This code snippet is available in this file in method getJWTSignedToken_nJWTLib(). I have used njwt module of Nodejs to create a JWT token. This is very useful website to validate and generate JWT token as per digital certificate.
Next we need to send JWT request to token URL – https://login.salesforce.com/services/oauth2/token
If JWT request is valid then Salesforce returns access_token , which can be used in subsequent requests to perform allowed operations in Salesforce via Nodejs application.
