ESLint Plugin for AssemblyScript

An ESLint plugin that helps developers write better AssemblyScript code by enforcing language-specific rules and best practices.

Overview

This plugin provides two sets of rules:

• Language Standards: Rules that enforce AssemblyScript language restrictions and prevent errors
• Performance Optimization: Rules that help improve code performance in WebAssembly

Plugins Included

Standard Rules (asPlugin.ts)

Enforces AssemblyScript language compatibility:

• dont-omit-else: Requires explicit else blocks for conditionals that don't have early return statements
• no-spread: Prevents use of spread syntax (...) which is not supported in AssemblyScript
• no-unsupported-keyword: Disallows TypeScript keywords not supported in AssemblyScript (any, never, undefined)

Performance Rules (perfPlugin.ts)

Optimizes code for better WebAssembly performance:

• array-init-style: Recommends using new Array<T>() instead of [] for initializing empty arrays

Configuration

See sample_config/sample_eslint.config.mjs for a detailed example of how to configure and use this plugin.
