📝 Walkthrough

Walkthrough

This PR introduces support for tsgo, an alternative TypeScript implementation, across development environments and build tooling. Configuration is added for VS Code and Zed editors, the TypeScript executor is updated with conditional logic to use tsgo when enabled, and the typescript package dependency is replaced with @typescript/native-preview.

Changes

Cohort / File(s)	Summary
Editor Configuration .vscode/settings.json, .zed/settings.json	Added experimental tsgo setting in VS Code and configured TypeScript to use tsgo and vtsls language servers in Zed.
Executor & Schema libs/tsc/src/executors/typecheck/executor.ts, libs/tsc/src/executors/typecheck/schema.d.ts, libs/tsc/src/executors/typecheck/schema.json	Updated executor to conditionally spawn tsgo or tsc based on a new tsgo boolean parameter; added corresponding schema definitions with descriptions.
Build & Dependency Configuration nx.json, package.json, tsconfig.base.json	Added tsgo: true option to typecheck target defaults; replaced typescript 6.0.2 dependency with @typescript/native-preview 7.0.0-dev; removed baseUrl compiler option from TypeScript config.

Poem

🐰 Hop, hop, tsgo now runs free,
Swift as rabbits, quick as can be,
From Zed to VS Code's domain,
TypeScript reimagined, faster to maintain!
Native preview hops into place, ✨

20-34: ⚠️ Potential issue | 🔴 Critical

Change the default tsgo parameter from false to true.

The executor defaults to spawning tsc on line 34, but the typescript package has been removed and replaced with @typescript/native-preview, which only provides the tsgo binary. All 13+ projects using the @riwi/tsc:typecheck executor with empty options will fail at runtime with "command not found: tsc".

Fix

-  { tsconfig = 'tsconfig.lib.json', tsgo = false },
+  { tsconfig = 'tsconfig.lib.json', tsgo = true },
