apex-highlight-web

Apex Syntax Highlighter (Web) is a lightweight, web-compatible Visual Studio Code extension that provides syntax highlighting for the Apex programming language and SOQL (Salesforce Object Query Language). This extension is powered by TextMate grammars, making it ideal for environments like vscode.dev and github.dev, where traditional language servers cannot run.

Features

• Syntax highlighting for Apex (.cls, .trigger, .apex) files
• Syntax highlighting for SOQL (.soql) files
• Fast and lightweight — no language server required
• Fully compatible with web-based VS Code environments

Why Use This?

Unlike Salesforce’s official Apex extension, which relies on a Java-based language server, this extension uses a declarative TextMate grammar. This allows it to run entirely in the browser, making it perfect for use in web-based editors and constrained environments.

Installation

You can install this extension from:

• Open VSX Registry
• Visual Studio Code Marketplace
