Use the Salesforce SDKs, along with other standard Salesforce APIs, to access org resources.

• Developer Guide: Access Salesforce Resources Best practices around accessing Salesforce resources.
• Reference: Salesforce SDK for Node.js Functions Reference documentation for the classes and methods of the SDK used to develop TypeScript functions.
• Reference: Salesforce SDK for Java Functions Reference documentation for the classes and methods of the SDK used to develop Java functions.
• Sample: SalesforceSDK_JS A JavaScript sample function that uses the SDK to insert and query records.
• Sample: SalesforceSDK_Java A Java sample function that uses the SDK to insert and query records.

Functions, unlike Apex, don't automatically handle data transactions for you. Transactions ensure that all related data changes are made at the same time and that they can be undone if necessary. To manage transactions in a function, use the UnitOfWork SDK class.

• Developer Guide: Access Salesforce Resources Best practices around accessing Salesforce resources using UnitOfWork.
• Developer Guide: Apex Patterns If you're used to how transactions work in Apex, see this document for how to transition to creating your own transactions with the SDK.
• Reference: Node.js SDK UnitOfWork class Reference documentation on the Node.js SDK UnitOfWork class.
• Reference: Java SDK UnitOfWork class Reference documentation on the Java SDK UnitOfWork class.
• Sample: UnitOfWork_JS A JavaScript sample function that shows how to use UnitOfWork to define your own transactions.
• Sample: UnitOfWork_Java A Java sample function that shows how to use UnitOfWork to define your own transactions.

Use JavaScript or TypeScript along with your favorite Node frameworks to build a function that your org can invoke.

Do you have Apex code that is hitting Apex compute limits? Transition your Apex code to a function using patterns and best practices, and take advantage of elastic auto-scaling in Salesforce Functions compute environments.

• Developer Guide: Functions Patterns for Apex Developers Development patterns and best practices for Apex developers developing functions.
• Developer Guide: Limits Understand how Salesforce Functions limits compare to Apex limits.
• Developer Guide: Permissions Understand how Salesforce Functions object permissions compare to Apex permissions.

Before you deploy your function, you can run and debug it locally.

• Developer Guide: Local Invocation Steps for starting your function locally, and invoking it.
• Developer Guide: Use Logs to Debug Debug your function via logs.

Learn how to integrate your function code and function invocation code in your testing pipeline.

• Developer Guide: Test and Validate Functions Best practices for testing functions.
• Developer Guide: Development and Application Lifecycle Workflow Details about automating function testing.
• Sample: UnitOfWork_JS A JavaScript sample that shows how to use, mock, and test UnitOfWork.
• Sample: UnitOfWork_Java A Java sample that shows how to use, mock, and test UnitOfWork.

Like any Salesforce org custom development, you need to manage how and where functions are tested and deployed. Functions compute environments are tied to orgs, helping you avoid deploying an in-development function to a production org.

• Developer Guide: Development and Application Lifecycle Workflow Details about automating function testing.

Before a Function can be invoked from a Salesforce org, it must be deployed to a Salesforce Functions compute environment associated with the org.

• Overview Understanding Salesforce Functions projects and compute environments.
• Developer Guide: Deploy a Function Steps for connecting an org with Salesforce Functions, creating compute environments, and deploying function projects to compute environments.

Salesforce makes it easy to invoke a deployed function from your org, using Salesforce features you're already familiar with, like Apex. You can invoke a function from your org synchronously or asynchronously as easily as calling an Apex method.

• Developer Guide: Deploy Function Invocation Using Apex Steps for invoking your deployed function from Apex, synchronously and asynchronously.
• Apex Reference Guide: Functions namespace Reference documentation for the Functions Apex namespace used to invoke functions from Apex synchronously or asynchronously. Includes examples of mocking a function invocation.

When invoked, functions use specific permission sets for data access. Understand what permissions you can set, which permission sets to use, and what user role runs the functions.

• Developer Guide: Function Permissions Details on the Functions permission sets.
