DBStudio Lite v0.1.0

Initial release of DBStudio Lite, a lightweight, modular desktop PostgreSQL client built with Go, Next.js, and Wails v2.

DBStudio Lite was developed using strict Test-Driven Development (TDD) and dependency injection principles, decoupling core database domain logic from presentation and transport layers.

Highlights

  • Connection Management & Profiles:

    • Connect via standard PostgreSQL connection URLs or discrete parameters (Host, Port, User, Password, Database, SSL Mode).
    • Save, list, and delete connection profiles with masked credential previews.
    • Profiles are persisted locally to disk using user-restricted permissions (0600) within the standard operating system configuration directory.

  • Schema & Metadata Inspection:

    • Automatic discovery and categorization of user tables grouped by schema (public, custom schemas).
    • Fast table filtering and search.
    • Column metadata inspection including SQL data types, nullability constraints, default expressions, and composite primary key detection.

  • Interactive Tabular Data Viewer:

    • Browse table records with clean visual handling of NULL values, booleans, timestamps, numbers, and structured JSON fields.
    • Telemetry reporting row counts and query execution latency in milliseconds.

  • Monaco SQL Console:

    • Full-featured SQL editor powered by Monaco Editor.
    • Syntax highlighting, autocomplete, line numbers, bracket matching, and auto-indentation.
    • Keyboard shortcuts (Ctrl+Enter / Cmd+Enter to execute).
    • Resizable split pane to adjust vertical proportions between editor and results.
    • 100% offline bundling with zero external CDN dependencies.

Architecture & Engineering

  • Interface-Driven Core: Core database capabilities (internal/db) depend exclusively on lean Go interfaces (Querier, Rows, Client, ConnectionStore). The entire unit test suite executes in-memory in milliseconds with zero live database dependencies.
  • Concurrency Safety: Connection lifecycles and client dispatch utilize read-write mutex locks (sync.RWMutex) to prevent race conditions during asynchronous frontend operations.
  • Decoupled Driver: Utilizes jackc/pgx/v5 through an internal adapter layer, ensuring the engine remains driver-agnostic.
  • Centralized Frontend State: Employs a dedicated DatabaseContext and reusable UI components built on Tailwind CSS v4 and shadcn/ui design tokens.
