At a glance
Explains how the @handsontable/react-wrapper package is built, from its components and settings mapping to selection handling and the generated TypeScript declarations.
- Changing HotTable, HotColumn or HotEditor in the React wrapper
- SKILL.md covers Components, Architecture, Build and test and Key files, plus 3 more sections
- Calls npm and tsc
- Fixing selection being lost when props change
What it does
The wrapper has four main pieces. `HotTable` is the public component, `HotTableInner` is a `forwardRef` layer that manages the instance lifecycle, `HotColumn` declares columns as children and `HotEditor` renders custom editors in a React portal. A `useRef()` holds the live instance, `SettingsMapper.getSettings()` turns props into settings, and every prop change calls `updateSettings()`. Around that call the code must save and restore the selection with `exportSelection()` and `importSelection()`, otherwise it resets.
Builds use Rollup 4 for CommonJS, ES module, UMD and minified output, tests run on Jest with React Testing Library, and the core package has to be built first because wrappers read from `handsontable/tmp/`. The TypeScript section warns that `scripts/prepare-types.mjs` uses an old `typescript` devDependency and swallows `tsc` errors, so a mangled `.d.ts` can still report success. Newer type syntax such as key remapping therefore belongs in core and gets imported.
When your agent uses it
- Changing HotTable, HotColumn or HotEditor in the React wrapper
- Fixing selection being lost when props change
- Debugging missing prop suggestions for HotTable or HotColumn in an IDE
- Touching the declaration build or `src/types.tsx`
Example prompts
- “Selection resets whenever I change the readOnly prop on HotTable. Find the cause in the wrapper.”
- “React users get no autocomplete for HotColumn props. Check how the .d.ts is generated.”
- “Add a new settings prop to the React wrapper and make sure the mapper passes it through.”
Requirements
- A checkout of the Handsontable repository with the core package built
What it can do on your machine
Read from SKILL.md and the folder at commit 68b5e97. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npmtsc
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Handsontable React Wrapper Development loads about 1.1k tokens when it runs. Until then it costs about 125 tokens; SKILL.md has 466 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 466 words (~1,136 tokens).
- name
- react-wrapper-dev
- path
- wrappers/react-wrapper/**
