Summary

  • add a new createPersesEsqlDatasource abstraction at peek/src/services/perses/esqlDatasource.ts
  • route shared ES|QL execution paths through that datasource in:
    • peek/src/hooks/useEsqlQuery.ts
    • peek/src/components/PanelContainer.tsx
  • add a Perses panel runtime seam in:
    • peek/src/components/perses/panelRegistry.ts
    • peek/src/components/perses/PersesPanelRenderer.tsx
  • adapt dashboard layout conversion through Perses layout helpers in:
    • peek/src/components/DashboardGrid.tsx
    • peek/src/components/perses/layoutAdapter.ts
  • add unit coverage for the datasource and new Perses seams in:
    • peek/tests/unit/persesEsqlDatasource.test.ts
    • peek/tests/unit/persesPanelRegistry.test.ts
    • peek/tests/unit/persesLayoutAdapter.test.ts

Why

This creates concrete migration seams for the Perses dashboard cutover: query execution now has a Perses-oriented datasource boundary, and panel/layout runtime wiring can evolve behind Perses-specific adapters without reworking each component call-site.

Validation

Generated by Update PR Body for issue #590

Introduce a Perses-oriented datasource abstraction and route shared query paths through it for migration groundwork.

/ai let's make sure we've fully implemented phase one and then let's work on phase two:

Phase 1 — ES|QL custom datasource plugin (foundation)
Create Perses datasource plugin package in-repo (e.g. peek/src/perses/esql-datasource/).
Plugin query model:
queryText (ES|QL)
timeRange support (?_tstart/?_tend parity)
parameters support (current dashboard variables from ParameterBar).
Plugin execution layer should reuse current request semantics from ElasticsearchClient (peek/src/services/es/client.ts:190-337) including auth/proxy handling.
Implement query response normalization to a frame format Perses panels consume.
Add cancellation/retry behavior parity with current hooks (peek/src/hooks/useEsqlQuery.ts:56-121).
Add contract tests with mocked ES responses + one integration test against the existing ES test harness.
Phase 2 — panel runtime and component migration
Replace Visualization registry dispatch with Perses panel registry wiring (peek/src/components/visualizations/vizRegistry.tsx:28-68).
Migrate panel rendering path in PanelContainer from custom Visualization to Perses panel renderer while keeping toolbar actions (refresh/export/edit/duplicate).
Port existing visualization options to Perses option schemas:
time series, bar, pie, gauge, stat, table, heatmap, scatter, histogram, markdown (peek/src/types.ts:26-118).
Keep ChartOptionsEditor as a thin wrapper over Perses option controls where available.
Preserve non-chart pages (Discover, Explore, Traces, Fleet) initially; only dashboard runtime changes in this phase.

📝 Walkthrough

Walkthrough

Replaces direct Elasticsearch client usage with a Perses ESQL datasource and request builder (createPersesEsqlDatasource, buildPersesEsqlRequest) and switches client.query(...) calls to datasource.execute(...). Introduces PersesPanelRenderer and a Perses panel registry (getPersesPanelEntry, getAllPersesPanelEntries). Adds a perses layoutAdapter to translate between Perses panel layouts and react-grid-layout formats. Updates PanelContainer, PanelEditor, ParameterBar, useEsqlQuery, useMarkdownEsql, ChartOptionsEditor, and DashboardGrid to use the new Perses abstractions and adds unit tests for the new modules.

Possibly related PRs

  • PR 725: Centralizes ES|QL request construction and modifies the same call sites now using buildPersesEsqlRequest/createPersesEsqlDatasource.
  • PR 513: Changes panel rendering and timeZone propagation through the rendering path, overlapping the new PersesPanelRenderer integration.
  • PR 524: Refactors the visualization registry APIs that the new Perses panelRegistry wrappers delegate to (getVizEntry, getAllVizEntries, VISUALIZATION_TYPES).

Implemented the requested follow-up by hardening phase 1 and wiring the first phase-2 runtime seam on this PR branch.

What changed

  • Added vi.unstubAllGlobals() cleanup in peek/tests/unit/persesEsqlDatasource.test.ts to prevent global fetch stub leakage.
  • Added Perses-oriented panel registry facade:
    • peek/src/components/perses/panelRegistry.ts
    • peek/src/components/perses/PersesPanelRenderer.tsx
  • Migrated dashboard panel runtime path to use the Perses panel renderer/registry seam:
    • peek/src/components/PanelContainer.tsx
    • peek/src/components/ChartOptionsEditor.tsx
  • Updated tests for the runtime migration:
    • peek/tests/component/PanelContainer.test.tsx
    • peek/tests/unit/persesPanelRegistry.test.ts

Validation

  • make lint
  • make test-unit (1001 tests passing)
  • make build

Also resolved the existing CodeRabbit review thread after applying the global unstub fix.

I investigated and attempted to fix the merge conflicts, but I’m blocked by a push limitation in this workflow.

ready_to_push_to_pr reports that the original PR head (64f4bdf52cd31ca37ad4143663aae6ae0494f60e) is no longer an ancestor after conflict-resolution rebase, and push_to_pull_request_branch will reject that rewritten history. The branch/main ancestry in this runner also reports as unrelated (git merge origin/main refuses without --allow-unrelated-histories), so I can’t produce a merge-conflict resolution commit that is both valid and pushable under the current constraints.

To proceed, a maintainer will need to perform the conflict resolution locally (or with force-push permissions/tooling that allows rewritten history) and then push the updated PR branch.

Resolve merge conflicts in PanelContainer.tsx, PanelEditor.tsx, and
useMarkdownEsql.ts by keeping the Perses datasource abstraction layer
(createPersesEsqlDatasource / buildPersesEsqlRequest) over the direct
ElasticsearchClient / buildEsqlRequest usage from main.

[MEDIUM] Escape interpolated \{\{var}} string values for ES|QL literals

interpolatePersesVariableTokens() inserts raw variable text into query strings. When a dashboard value contains a single quote (for example O'Reilly) and the query uses the current documented pattern from this PR (env == '\{\{env}}'), the generated ES|QL becomes invalid (env == 'O'Reilly').

Please escape string-like values (at least single quotes) before substitution, or convert \{\{name}} usage into bound ?name parameters so query semantics are preserved for arbitrary user input.

When a dashboard variable value contains a single quote (e.g. O'Reilly),
interpolating it directly into an ES|QL query string literal produces
invalid syntax. This doubles single quotes in replacement values, which
is the standard ES|QL escape sequence for a literal single quote inside
a string.
