Export Presets & Desktop Polish

Supabase and Neon PostgreSQL export presets land alongside desktop file-change reload prompts, better recent files, local asset fixes, and onboarding SQL samples.

0.6.0Core
0.2.0Desktop

Added
@titanbase/editorexport presets
  • Supabase and Neon tabs in the export modal.
  • Preset-specific PostgreSQL SQL headers and .supabase.sql / .neon.sql filenames.
  • Clear local-first warnings: no credentials, no live connections, no branch creation, no migration execution.
apps/desktopfile workflow
  • File-changed-on-disk prompt for opened .titan.json files.
  • Reload or keep-editing choices when the file changes externally.
  • Improved recent-file presentation with last-opened timestamps.
examples/sql
  • Blog, SaaS, Supabase-style PostgreSQL, and Neon/PostgreSQL onboarding SQL samples.
  • Importer tests that verify the SQL samples load cleanly with no error-level diagnostics.
Fixed
apps/desktop
  • Packaged Electron builds now load bundled logos and renderer assets from local relative paths.
  • Desktop package metadata reflects [email protected].
Desktop 0.2.0

Desktop Polish

The desktop app gets a more local-file-native workflow: file-change prompts, cleaner recent files, Supabase/Neon exports, and packaged asset fixes.

UnsignedStatus
Added
titanbase-desktop
  • File-change detection prompt for opened .titan.json files.
  • Supabase and Neon export presets through the desktop export flow.
  • Recent schemas with clearer copy and last-opened timestamps.
Changed
titanbase-desktop

Desktop 0.1.0

Desktop App

Titanbase now ships as a free, open-source Electron desktop app for macOS, Windows, and Linux — with native file open/save, SQL import, compare, and migration export, fully offline.

3Platforms
ElectronRuntime
NoneAccount
Added
apps/desktopnew free OSS desktop app
  • Electron app built on the shared visual editor and schema packages.
  • Native open, save, Save As, SQL import, compare, and migration-draft export through OS dialogs.
  • Native menus and shortcuts, recent files, OS file-open events, drag and drop, and unsaved-change prompts.
  • Bundled local renderer in production — no dependency on the hosted website; fully offline.
  • Electron Builder targets for macOS (dmg/zip), Windows (nsis), and Linux (AppImage/deb).
  • Hardened security: context isolation, renderer sandboxing, Node integration disabled, and a narrow typed preload bridge.
@titanbase/editor
  • Shared desktop file adapter while preserving browser picker and download behavior.
  • Source-kind context in file status to distinguish blank, template, .titan.json, and SQL-imported schemas.
v0.5.0

Schema Diff & Migrations

Compare two schemas and generate PostgreSQL migration drafts — added, removed, and changed objects, destructive-change warnings, and downloadable SQL.

NewSchema diff
NewMigration drafts
PostgreSQLTarget
Added
@titanbase/coreschema diff
  • Framework-independent diffSchemas() API.
  • Deterministic project, table, column, relation, index, enum, and enum-value changes with stable matching and conservative rename detection.
  • Destructive and breaking change classification, matching warnings, summary counters, and semantic metadata filtering.
@titanbase/export-postgresmigration drafts
  • Deterministic generatePostgresMigrationDraft() API.
  • Draft SQL for table, column, constraint, foreign-key, index, enum-addition, rename, and comment changes.
  • Destructive and breaking metadata plus review warnings for data loss, casts, inferred constraint names, locking, and enum limitations.
  • Focused migration-draft tests and PostgreSQL import-to-migration integration coverage.
@titanbase/editor
  • Compare action and schema diff modal with grouped changes, severity badges, before/after values, object selection, and invalid-file handling.
  • Migration preview from Schema Diff with warning review, SQL copy, and .sql download.
Changed
@titanbase/export-postgres
  • Extracted shared identifier, type, column, table, index, and foreign-key formatting helpers for consistent full exports and migration drafts.
v0.4.0

Import & Mobile

PostgreSQL SQL import lands, the editor becomes fully responsive and touch-friendly, and diagnostics get much richer and more actionable.

NewSQL import
25Importer tests
ReadyMobile
Added
@titanbase/import-postgresnew package
  • Deterministic, browser-safe PostgreSQL DDL parsing.
  • Enums, tables, column and table constraints, foreign keys, indexes, comments, quoted identifiers, and namespaces.
  • Line-aware warnings for unsupported statements, expression indexes, and unresolved references.
  • 25 importer tests, including a PostgreSQL import/export integration scenario.
@titanbase/editor
  • PostgreSQL .sql import from the start screen, toolbar, empty canvas, and Project Overview.
  • Non-blocking import report for unsupported SQL, with a failure state that preserves the schema.
  • Hover call-to-action affordances on the start screen cards.
  • Responsive viewport configuration for correct mobile rendering and safe areas.
  • Actionable diagnostics for projects, tables, columns, relations, indexes, enums, and metadata.
  • Diagnostic context, help text, severity counts, issue codes, and direct object selection.
Changed
@titanbase/editor
  • Reworked start screen cards into a balanced, uniform grid with a refined Recommended badge.
  • Start screen scrolls on mobile; hero, header, and cards stack on small viewports.
  • Compacted the toolbar; Website and Docs became icon-only buttons; Import SQL shortened to Import.
  • Toolbar is horizontally scrollable so all actions stay reachable on narrow screens.
Fixed
@titanbase/editor
  • Start screen cards reflow cleanly (4 → 2 → 1) with no orphaned card.
  • Canvas now pans on touch devices.
  • Inspector sidebar no longer clips off-screen on narrow windows.
  • Start screen header no longer overlaps the Docs/GitHub actions.
  • Fixed the oversized website mark icon.
v0.3.0
