Fixes #6078

Raw process.env.NODE_ENV references throw process is not defined when @tanstack/table-core is consumed in vanilla JS without a bundler (e.g. Rails importmap).

Add a safe isDev() utility that checks for the existence of process before accessing it, and replace all dev-only guards across table-core.

function isDev(): boolean {
  return typeof process !== "undefined" && process.env?.NODE_ENV !== "production"
}

Summary by CodeRabbit

  • Bug Fixes

    • Improved development-mode compatibility in browser and worker environments by avoiding reliance on Node.js-specific environment globals.
    • Standardized development warnings and diagnostic logging across table features, including columns, rows, filtering, sorting, and aggregation.
  • Refactor

    • Centralized development-environment detection for more consistent debug behavior and diagnostics.

Fixes TanStack#6078

Raw `process.env.NODE_ENV` references throw `process is not defined` when
@tanstack/table-core is consumed in vanilla JS without a bundler
(e.g. Rails importmap). Add a safe isDev() utility that checks for the
existence of `process` before accessing it, and replace all dev-only
guards across table-core.

📝 Walkthrough

Walkthrough

The PR adds an exported isDev utility that safely detects development mode without requiring Node.js globals. Existing table-core warnings, errors, logging, and debug checks now use this utility.

Changes

Development-mode detection

Layer / File(s) Summary
isDev utility and memoization integration
packages/table-core/src/utils.ts
Adds isDev() and uses it for tableMemo debug initialization and options.
Core table development checks
packages/table-core/src/core/columns/constructColumn.ts, packages/table-core/src/core/columns/coreColumnsFeature.utils.ts, packages/table-core/src/core/rows/coreRowsFeature.utils.ts, packages/table-core/src/core/table/constructTable.ts
Uses isDev() for column warnings, row errors, and table-construction logging.
Feature and worker development checks
packages/table-core/src/features/*/*.utils.ts, packages/table-core/src/worker/createWorkerRowModel.ts
Uses isDev() for filter, aggregation, sorting, global-filter, and worker warnings.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to 0a238

The change currently cannot compile because isDev is imported from its own file while also declared locally. Remove the self-import before merging.

Remove the self-import of isDev.

The self-import conflicts with the local export function isDev declaration and prevents TypeScript compilation. Remove the import; tableMemo can call the local function directly.

Every time I've tried to add code like this in a centralized way in the past around process.env?.NODE_ENV, I thought that it ended up breaking tree-shaking.
