Guides Node.js scripts and shared modules in the Handsontable monorepo using .mjs files, native APIs, and asynchronous file operations. It covers task registration, error handling, and compatibility across Linux, macOS, and Windows.

原文查看原文说明

Use when creating or modifying any .mjs file in the Handsontable monorepo - scripts, utilities, or library modules. Covers .mjs conventions, native node: imports, top-level await, cross-platform compatibility, and fs/promises async patterns. Trigger on any new .mjs file creation, not just files in scripts/ directories.

Writing Node.js .mjs Modules

All Node.js-side code (scripts, utilities, library modules, Playwright helpers, build tooling) is ESM .mjs.

File conventions

  • Extension: .mjs for all Node.js-side code.
  • Location: scripts/ for CLI-invoked scripts, lib/ for shared modules; package-specific paths are fine (performance-tests/lib/, wrappers/react-wrapper/scripts/).
  • Invocation: node scripts/your-script.mjs from package.json scripts, or as a cmd in handsontable/scripts/tasks.json.

Adding npm scripts to the handsontable core package

handsontable/ uses a unified dispatcher. Put every command in handsontable/scripts/tasks.json and keep a thin shim in package.json:

"my-task": {
  "cmd": "node scripts/my-script.mjs",
  "deps": ["build:styles"],
  "mode": "inherit"
}
"my-task": "node scripts/run.mjs my-task"
FieldRequiredValuesPurpose
cmdyesshell stringRun via spawn(..., { shell: true })
depsnotask name arrayTasks that must complete first (DAG scheduler in parallel mode, sequential in direct invocation)
modenoquiet (default) | inherit | interactivequiet = spinner; inherit = stream output (linters); interactive = full TTY pass-through (Jest)
cwdnopath relative to handsontable/Working directory override
passthroughnobooleanAppend extra CLI flags (after --) to the cmd
notenostringAnnotation only

Pipelines go in the pipelines block:

"pipelines": {
  "my-pipeline": {
    "before": ["clean"],
    "tasks": ["my-task", "other-task"],
    "after":  ["prepare-package-for-publish"]
  }
}

before and after run sequentially; tasks run sequentially with --sequential or via DAG with --parallel.

Wrapper packages and performance-tests/, visual-tests/ take scripts directly in their own package.json (no run.mjs dispatcher).

Imports and top-level await

  • Prefix built-ins with node: (import { readFile } from 'node:fs/promises', node:path, node:url, node:child_process, node:util).
  • Use top-level await in module scope; wrap in try/catch only for an error boundary.

Native modules over dependencies

Do not add third-party dependencies for what Node.js does natively.

Parse CLI argsnode:util parseArgs() or process.argvyargs, commander
Path manipulationnode:pathslash, normalize-path
Glob matchingnode:fs readdir + filter (glob/fast-glob only for complex patterns)glob, fast-glob otherwise

Cross-platform (Linux, macOS, Windows)

  • package.json scripts: use Node helpers in place of bash constructs (if [ ], mv, rm -rf, a && b || c conditionals). Plain && sequencing is fine.
  • Build paths with node:path join().
  • Use async node:fs/promises (readdir, rename, rm, access).
  • __dirname equivalent: import.meta.dirname (Node 21+) or dirname(fileURLToPath(import.meta.url)).
  • Reference: wrappers/react-wrapper/scripts/prepare-types.mjs.

Existence check:

const exists = async (path) => access(path).then(() => true, () => false);

Error handling

  • Set process.exitCode = 1 on failure so cleanup finishes.
  • Comment every silent catch with why the error is swallowed.
  • Include the file path or operation in error messages.
