The JavaScript ecosystem is experiencing a major performance boost with TypeScript Go, offering 10x faster type checking while catching errors missed by the original implementation. This rewrite represents a fundamental shift in developer tooling for 2026, creating faster feedback loops that benefit both human developers and AI assistants working on codebases.

Beyond TypeScript, developers are migrating from Prettier to Oxfmt and from ESLint to Oxlint. Oxlint uniquely supports ESLint plugins through an ESLint plugin shim and NAPI-RS, enabling type-aware linting powered by TypeScript Go. These tools create faster, more consistent codebases with strict guardrails that guide both humans and LLMs toward better code quality.

The @nkzw/oxlint-config package provides comprehensive linting with strict defaults - error-only rules, consistent style enforcement, and bug prevention. Combined with optimizations like npm-run-all2 and ts-node, this tooling stack enables instant restarts on file changes and parallel script execution. OpenClaw already uses this configuration to ship code at "rocket speed."
