devtools

Connect TanStack Table instances to developer tools for inspecting options, state, features, columns, rows, and row models. Diagnose missing connections, assign unique table keys, and manage registration replacement and cleanup.

OriginalShow the original description

Register TanStack Table targets and inspect options, state, features, columns, rows, and row models with @tanstack/table-devtools. Load for missing connections, required unique table options.key, target replacement/cleanup, or an explicit request for production Devtools entrypoints.

See how to install

Good for

  • Inspect table options, state, columns, and rows
  • Diagnose tables missing from developer tools
  • Assign distinct keys to multiple tables
  • Review registration replacement and cleanup

Review the instructions the agent will receive before you install.

Setup

Framework adapters should use their lifecycle hook or injector. The framework-neutral registration primitive is:

import { constructTable, tableFeatures } from '@tanstack/table-core'
import { storeReactivityBindings } from '@tanstack/table-core/store-reactivity-bindings'
import { upsertTableDevtoolsTarget } from '@tanstack/table-devtools'

const features = tableFeatures({
  coreReactivityFeature: storeReactivityBindings(),
})

const table = constructTable({
  key: 'users-table',
  features,
  columns: [],
  data: [],
})

const cleanup = upsertTableDevtoolsTarget({ table })
cleanup()

Core Patterns

Give every live table a descriptive unique key

The non-empty options.key is both registry identity and panel label. Use stable application identity, not an array index.

Let adapter lifecycles own registration

React/Preact/Solid/Vue hooks and the Angular injector register and clean up at the correct time. Use core target functions only for unsupported frameworks or infrastructure code.

Keep ordinary Devtools development-only

Default entrypoints export no-op panels/plugins outside development. Use /production only when the application explicitly chooses production inspection and its security/bundle implications.

Common Mistakes

HIGH Missing key skips registration

Wrong: register a table whose options.key is absent or whitespace.

Correct: set a stable value such as key: 'billing-invoices' before registration.

The registry logs the missing-key error and returns without adding a target.

Source: TanStack/table:packages/table-devtools/src/tableTarget.ts

HIGH Two tables share one key

Wrong: use key: 'table' for simultaneous tables.

Correct: use unique domain identities such as users-table and orders-table.

Upserting a different table under an existing key replaces that registration.

Source: TanStack/table:packages/table-devtools/src/tableTarget.ts

MEDIUM Production panel expected by default

Wrong: debug why the normal entrypoint renders nothing in production.

Correct: keep Devtools development-only unless production inspection was explicitly requested; then import the documented /production entrypoint.

Default production exports intentionally use no-op implementations.

API Discovery

Inspect node_modules/@tanstack/table-devtools/dist/index.d.ts, tableTarget.d.ts, and production.d.ts. Framework registration belongs to the matching @tanstack/<framework>-table-devtools package.
