TanStack/table
The source walks cover startup, a sorting action, worker processing, asynchronous query pagination, and browser preference persistence. These traces name execution order and retain important bypass and fallback conditions. They describe code behavior without asserting that a browser session or test run reproduced it.
- Sorting-example startup proceeds document.getElementById('root') → ReactDOM.createRoot(...).render(<App />) → makeData(1_000) in useState → useTable with statically registered sorting features and columns; a missing root throws.
- useTable's initial useState constructs a table with reactReactivity, attaches Subscribe/FlexRender, and creates a render-phase source. constructTable resolves defaults, creates effective atoms/store, then runs each feature's initialization and API hook in one ordered pass.
- A sortable header click executes getToggleSortingHandler → column_toggleSorting → table_setSorting → setStateSlice → onSortingChange. Disabled columns ignore the event; multi-sort uses isMultiSortEvent and the toggle selects add/remove/toggle/replace behavior.
- After sorting state changes, createSortedRowModel reads sorting and the pre-sorted model, skips empty or unusable sort specifications, resolves comparators, sorts copied arrays recursively, and the example renders the first ten getRowModel rows through FlexRender.
- Worker-example startup executes the '/' route loader → getInitialData server function → makeData(10_000) → Route.useLoaderData → useTable. Its module-scoped handle creates a Worker lazily on client reads; without a Worker global, synchronization returns and row-model getters use pre-stage fallbacks.
- A worker-stage read executes syncTableWorker → ensureWorker → data post when identity changes → postProcess. initTableWorker receives data/state and serializes stage results; handleResult rejects stale requests/data, updates stage versions and worker state, then triggers a trailing request if more input arrived.
- Query-example sorting invokes its controlled onSortingChange, updates sorting and resets pageIndex to zero, changes the useQuery key, calls fetchData, and supplies the resulting page back to useTable; manual flags prevent duplicate client filtering/sorting/pagination.
- Theme persistence executes ModeToggle menu click → context setTheme → localStorage.setItem → React state update → ThemeProvider effect updating root classes. On remount, getItem and isTheme restore the choice; system mode resolves matchMedia when the effect runs.
