What programming languages and frameworks does Salesforce Extensions for VS Code support?

It supports Apex, Lightning Web Components (LWC), Aura, Visualforce, and SOQL. TypeScript is now fully supported for building and developing Lightning Web Components alongside the standard JavaScript workflow.

Does this extension include AI-assisted development features?

Yes, it bundles salesforcedx-einstein-gpt, which provides a Dev Assistant for writing and documenting code, inline autocompletion, and Apex/LWC test case generation.

Can I install only specific extensions instead of the full pack?

Yes, each extension (salesforcedx-vscode-core, -apex, -apex-replay-debugger, -lightning, -visualforce, -soql, -slds, etc.) is independently listed on the VS Code Marketplace, so teams can install only the pieces they need.

What debugging capabilities does this extension provide?

It includes an Apex replay debugger that steps through Apex debug logs, allowing you to replay past executions.

What output formats are supported for SOQL query results?

SOQL query results can be exported to .csv or .json format.

Overview

Salesforcedx Vscode

Salesforce Extensions for VS Code is the official Salesforce DX extension family, covering Apex and LWC development, Aura and Visualforce editing, a visual SOQL builder, static code analysis, and Einstein GPT AI assistance. Use it when developing on the Salesforce platform in VS Code and wanting integrated CLI, debugging, and AI-assisted coding tools rather than separate extensions.

What it does

Salesforce Extensions for VS Code is the official source for the Salesforce DX extension family: an installer pack (salesforcedx-vscode) that pulls in core CLI integration, Apex language support and replay debugging, Aura/Lightning and Visualforce editing, a visual SOQL query builder, Salesforce Lightning Design System tooling, generative-AI dev assistance (Einstein GPT), static code analysis, a live Lightning Web Component preview, and a metadata relationship visualizer.

When to use - and when NOT to

Use it when developing Salesforce Apex, Lightning Web Components, Aura components, or Visualforce pages in VS Code and you want CLI integration, debugging, and AI-assisted coding in one place rather than assembling separate extensions and manually shelling out to the Salesforce CLI. It is specific to Salesforce DX development; teams not building on the Salesforce platform have no use for it.

Inputs and outputs

Install the top-level salesforcedx-vscode extension pack from the VS Code Marketplace to get all extensions at once, or install individual ones - -core, -apex, -apex-replay-debugger, -lightning, -visualforce, -soql, -slds, -einstein-gpt, sfdx-code-analyzer-vscode, -ui-preview, -metadata-visualizer-vscode - separately depending on what you need. Each extension interacts with the Salesforce CLI or platform-specific language servers, the Apex Language Server or VS Code's HTML language server for Aura/Visualforce, and reads/writes standard Salesforce project files, Apex debug logs, and metadata.

Integrations

The Salesforce CLI, the Apex Language Server, VS Code's built-in HTML language server, ESLint and Apex PMD, now folded into the v5 Code Analyzer extension that statically analyzes both Apex and JavaScript for problems, Salesforce Lightning Design System tokens (code completion, syntax highlighting, and validation for recommended tokens and utility classes), and Einstein GPT generative-AI capabilities for Apex/LWC autocompletion, documentation, and test generation. The SOQL extension provides a form-based visual query builder that shows results as you build and exports them to CSV or JSON, prompting for a name and folder when the query isn't already a file on disk. The UI Preview extension renders Lightning Web Components directly in VS Code with automatic updates on save, and the Metadata Visualizer extension diagrams Salesforce metadata relationships in real time, including metadata generated by AI tools like Agentforce Vibes. TypeScript is now fully supported for creating and developing Lightning Web Components end to end.

Who it's for

Salesforce developers working in VS Code who want integrated Apex, LWC, Aura, and Visualforce editing, debugging, static analysis, metadata visualization, and AI-assisted coding without switching between separate tools.

Source README

Salesforce Extensions for VS Code

Introduction

This repository contains the source code for Salesforce Extensions for VS Code: the Visual Studio Code (VS Code) extensions for Salesforce DX.

Currently, we have the following extensions:

salesforcedx-vscode
A top-level extension pack that automatically installs the following extensions for you.
salesforcedx-vscode-core
This extension interacts with the Salesforce CLI to provide basic Salesforce DX functionality.
salesforcedx-vscode-apex
This extension uses the Apex Language Server to provide features such as syntax highlighting and code completion.
salesforcedx-vscode-apex-replay-debugger
This extension enables VS Code to replay Apex execution from Apex debug logs.
salesforcedx-vscode-lightning
This extension supports Aura component bundles. It uses the HTML language server from VS Code.
salesforcedx-vscode-visualforce
This extension supports Visualforce pages and components. It uses the HTML language server from VS Code.
salesforcedx-vscode-soql
This extension enables you to interactively build a SOQL query via a form-based visual editor, view the query as you build, and save query results to a .csv or .json file. If the query is not a file on disk, export prompts for a name and folder like SFDX: Create Query in SOQL Builder.
salesforcedx-vscode-slds This extension simplifies working with the Salesforce Lightning Design System (SLDS). It provides code completion, syntax highlighting, and validation with recommended tokens and utility classes.
salesforcedx-einstein-gpt This extension uses generative AI to make Salesforce development in Visual Studio Code richer with features such as a Dev Assistant that helps with writing, documenting, and understanding code. It also provides inline autocompletion, and test case generation for Apex and LWC code.
sfdx-code-analyzer-vscode This extension scans your code using multiple rule engines to produce lists of violations that you can use to improve your code. v5 also includes all the functionality of the ESLint and Apex PMD extensions. Now, the Salesforce Code Analyzer extension statically analyzes both your Apex and JavaScript code to quickly find problems.
salesforcedx-vscode-ui-preview This extension enables you to preview Lightning Web Components directly within VS Code with automatic updates on save, allowing you to iterate quickly without deploying code.
salesforcedx-metadata-visualizer-vscode This extension creates visual diagrams of Salesforce metadata in real-time, making it easier to understand its structure and relationships compared to reviewing raw metadata files. You can visualize metadata generated by AI using Agentforce Vibes or from your SFDX project enabling you to easily understand and analyze code.
