See https://github.com/actions/runner-images/issues/11101 </small> --- ## Quick Start - In a VS Code project using any of the [supported databases](#supported-databases), ensure your database is properly configured and accessible from your application code. - For [zero-config environments](#1-zero-config-automatic-database-loading), DevDb automatically discovers and [auto-loads your database](#loading-databases). View your database by opening the DevDb view like in the screenshot shown, or by [using the shortcut](#keybinding). > [!NOTE] > DevDb also provides several [Language and Framework Integrations](#language-and-framework-integrations) ### UI Actions and Key Map - `Cmd + K + D` to toggle the view panel - `Cmd + K + G` to go to a table - `Cmd + Click` table name in the sidebar to open the table in the current tab - `Cmd + Click` on a database value to edit it - Click any value to preview it in the pane (useful for viewing prettified JSON string values) - The right pane offers options to view the current table schema or selected value - During edit sessions (activated during data edit/delete), the control box appears as shown in the screenshot - During edit sessions: `Cmd + Z` to undo changes, `Cmd + Y` to redo changes, and `Cmd + S` to save changes - Added new "Suggest New Feature" button ### One-click Actions (Data Manipulation) - Click the trash icon on a table row to delete it - Click the `Set null` button on a database value to set the value to `null`  ## Supported Databases Currently supported databases: - SQLite - MySQL - MariaDB - PostgreSQL - Microsoft SQL Server ## Loading Databases DevDb can automatically discover and load your database using connection details from your VS Code workspace ([zero-config](#1-zero-config-automatic-database-loading) mode). When this zero-config auto-discovery isn't available, a [configuration file](#2-config-based-database-loading) option is provided. ### 1. Zero-config (Automatic Database Discovery) No [configuration file](#2-config-based-database-loading) is needed when the workspace root contains any of the following: 1. Applications managed by [DDEV](https://ddev.com) 1. [Adonis](https://adonisjs.com) using default .env config for MySQL and PostgreSQL (with Lucid ORM) 1. [Django](https://www.djangoproject.com) with settings.py for SQLite, MySQL, and PostgreSQL 1. [Ruby on Rails](https://rubyonrails.org) with config/database.yml for SQLite, MySQL, and PostgreSQL 1. [Laravel](https://laravel.com) with default local SQLite database 1. Laravel with default .env config for MySQL/MariaDB, PostgreSQL, and Microsoft SQL Server 1. Containerized Laravel MySQL (Laravel Sail) with default .env/docker-compose.yml config (including [dev containers](https://code.visualstudio.com/docs/devcontainers/containers) support) ### 2. Config-based Database Loading If [zero-config](#1-zero-config-automatic-database-loading) support isn't available for your environment, create a `.devdbrc` file in your project root with your database connection details. > [!WARNING] > Exclude the `.devdbrc` config file from version control by adding it to `.gitignore`. This protects sensitive information and allows team members to use different database configurations. The configuration file should contain a single array of database connection objects. DevDb provides rich editing features for `.devdbrc`: - **JSON Schema Validation**: Automatic configuration validation - **IntelliSense**: Autocompletion for all fields, including `type` - **Snippets**: Quick configuration templates: - `devdb mysql`: MySQL configuration - `devdb mariadb`: MariaDB configuration - `devdb postgres`: PostgreSQL configuration - `devdb sqlite`: SQLite configuration - `devdb mssql`: Microsoft SQL Server configuration #### Configuration File Example ```json [ { "name": "My test MySQL database", "type": "mysql", "host": "127.0.0.1", "port": "3306", "username": "root", "password": "12345", "database": "test" // <-- the database to show in VS Code DevDb view }, { "type": "sqlite", "path": "/path/to/database.sqlite" }, { "name": "My MSSQL database", "type": "mssql", "host": "localhost", "port": "1433", "username": "sa", "password": "YourPassword123", "database": "master", "options": { "trustServerCertificate": true } } ] ``` ## Tools and Framework Integrations ### Context Menu Entry Open any database table in DevDb by right-clicking its name/model/entity from the editor in **any** framework/programming language. Example from a Node.js app  ### Laravel #### Eloquent Model Code Lens DevDb provides Code Lens features for: - Viewing the underlying table for the Eloquent model - Generating a factory for the model (automatically pre-filled with real data from the underlying table)  > [!NOTE] > Factory Generation is also available via the context menu #### Query Explainer The Query Explainer integrates with [MySQL Visual Explain](https://mysqlexplain.com) to optimize SQL queries by analyzing MySQL's query execution plan. Usage: 1. Open a Laravel PHP file containing SQL query (Eloquent or `DB` facade) 2. Select the SQL query to analyze 3. Click the `Explain query` Code Lens or select `Explain query` from the context menu 4. View the explanation in your browser or copy the URL  > [!NOTE] > VS Code [multi-root workspaces](https://code.visualstudio.com/docs/editor/multi-root-workspaces) support is in development. Track progress [here](https://github.com/damms005/devdb-vscode/issues/68). <!-- TODO: update when completed --> ### MCP Configuration 1. As shown in screenshot, click the hammer icon to copy the MCP settings. 1. In your IDE's MCP settings file (e.g. `.vscode/mcp.json`, `windsurf/mcp_config.json`, etc.), paste the copied JSON as one of the available MCP servers. Your IDE/AI-tool should now be able to use your database details.   ## URI Handler DevDb provides a custom URI handler that allows you to open specific database tables directly from external applications or links. This is useful for integrating DevDb with other tools or creating shortcuts to frequently accessed tables. ### URI Format The URI format follows this pattern: ``` vscode://devdb/open/table?connectionId=123&database=main&table=users&workspace=... ``` Parameters: - `connectionId`: The ID of the database connection - `database`: The database name - `table`: The table name to open - `workspace`: (Optional) The workspace path ## Support You can support the development of DevDb by [contributing](#contribution) or by [sponsoring the development](https://github.com/sponsors/damms005).
