Roadmap

Open Grid is an MIT-licensed, multi-framework data grid foundation. The roadmap is organized around public API quality, renderer consistency, accessibility, performance regression safety, and dependable releases.

0.1.0 Release

• [x] Framework-agnostic core with React, Vue, and Svelte adapters.
• [x] Maintained styled UI packages and unstyled primitive contracts.
• [x] Sorting, filtering, grouping, tree data, selection, editing, clipboard, export, pagination, column management, and row/column virtualization.
• [x] Server-side, grouping, tree, and export examples.
• [x] Package metadata, npm pack validation, release planning, dry-run, and guarded publish workflows.
• [x] Public README, documentation site, contribution guide, conduct policy, security policy, issue templates, and pull-request template.
• [x] Required aggregate CI and release gates with expensive release work skipped for unrelated changes.
• [x] Open Grid-owned bundle, DOM, heap, core-scale, server, browser behavior, and accessibility regression coverage.
• [x] Complete the first npm publication and continuously verify package installation, ESM imports, TypeScript use, and a Svelte build from a clean external project.
• [x] Complete the first GitHub Pages deployment from main.

Release-quality hardening

• [x] Publish the pre-1.0 compatibility and deprecation policy and check generated declaration contracts in CI.
• [x] Separate required package-owned bundle budgets from diagnostic framework app bundle measurements.
• [x] Install staged tarballs into a temporary external project before release and verify imports, types, and framework compilation.
• [x] Keep React 18/19, Vue 3.4+, and Svelte 4.2.20/5 compatibility checks explicit.
• [x] Add direct React adapter and Vue UI rendering tests instead of allowing empty package test suites.

0.2.0 Release

Open Grid 0.2.0 was published on 2026-09-27 after the protected publish workflow and the final manual UI and accessibility review completed. See the GitHub release and release record.

• [x] Define instance-scoped localization contracts for built-in labels, status text, controls, and accessibility labels across React, Vue, Svelte, and primitives.
• [x] Expand typed custom renderer parity across React, Vue, and Svelte.
• [x] Add product toolbar and loading, error, and empty-state composition points without coupling product UI to the grid core.
• [x] Version persisted preference migrations and document upgrade behavior.
• [x] Expand task-oriented API reference and integration examples from user reports.
• Continue keyboard, screen-reader, forced-colors, mobile reflow, server-data, and export improvements where real integration evidence identifies a gap.

0.3.0 Release Candidate

Open Grid 0.3 focuses on server-owned data workflows. The maintained React, Vue, and Svelte examples now share the framework-neutral request lifecycle for sequencing, cancellation, stale-response protection, retained data, and retry while keeping query construction and successful data commits in product state.

• [x] Accept a server-owned rowCount, derive page count when needed, and expose the exact total through shared accessibility primitives across all three UI renderers.

• [x] Define a framework-neutral request lifecycle contract for cancellation, stale-response protection, retry, and retained data.

• [x] Adopt that lifecycle in the maintained React, Vue, and Svelte server examples and document the product/server ownership boundary.

• [x] Complete cross-framework browser and accessibility regression coverage for the resulting server loading, error, retry, and pagination states.

• [ ] Complete release artifact and performance gates for the final 0.3.0 candidate.

• [ ] Complete the source-bound manual UI and accessibility review after the release preparation PR is merged.

• [ ] Publish all ten packages and the open-grid-v0.3.0 GitHub release.

Performance Direction

Release decisions use only Open Grid-owned measurements. Deterministic bundle, DOM, heap, core, server, and cross-framework behavior gates remain mandatory. Longer browser timing matrices are diagnostic until a stable source-bound baseline policy is accepted. See Performance Policy.

Any future external comparison belongs in an independent benchmark project so this repository, its dependency graph, and its release health remain focused on Open Grid.
