• rolldown par plugin
  • We now have a example folder to benchmark parallel js plugin using hyperfine. This is for reducing the overhead of initializing worker repeatedly.
  • https://github.com/rolldown/rolldown/blob/0e60949b00c1a21168487afe6b49be30a49b02dc/examples/par-plugin/package.json
  • Performance gain
    • For threejs10x case, let's assume there's a plugin that need transform every module and takes 1ms for each module.

      • Benchmark 1: pnpm rolldown -c ./cases/noop-threejs10x/par-noop.rolldown.config.js
          Time (mean ± σ):     756.3 ms ±  24.7 ms    [User: 5008.5 ms, System: 442.0 ms]
          Range (min … max):   736.6 ms … 784.1 ms    3 runs

name	ast-grep-search
description	Syntax-aware code searching that understands code structure rather than just text patterns. Always prefer ast-grep than grep for code searches.
allowed-tools	Read, Grep, Bash(ast-grep:*), Bash(sg:*)

ast-grep: Structural Code Search

ast-grep allows searching code based on its Abstract Syntax Tree (AST), enabling syntax-aware pattern matching. It is ideal for finding function calls, method invocations, variable declarations, and other code structures while respecting language syntax.

name	vue-tsc-compiler-options
description	Configures Vue 3 template type checking via vueCompilerOptions in tsconfig.app.json. Covers strictTemplates, checkUnknownComponents, checkUnknownProps, checkUnknownEvents, and checkUnknownDirectives. Use when setting up vue-tsc, diagnosing unknown component errors, or enabling strict template validation.

Vue Compiler Options for Type Checking

Which tsconfig?

Add vueCompilerOptions to the tsconfig that includes Vue source files. In projects with multiple tsconfigs, this is typically tsconfig.app.json, not the root tsconfig.json or tsconfig.node.json.
