This interface enables developers to build rich applications on top of MarkiTect's data with flexible querying capabilities. + +## Features + +- **Complete Type Safety**: Strongly-typed GraphQL schema with comprehensive field definitions +- **Flexible Querying**: Query exactly the data you need with GraphQL's selective field syntax +- **Rich Data Access**: Access markdown files, schemas, ASTs, and computed fields +- **Search Capabilities**: Full-text search across files and schemas with relevance scoring +- **Pagination Support**: Efficient pagination for large datasets +- **Real-time Introspection**: Schema introspection and GraphQL Playground for development +- **Multiple Access Methods**: HTTP server, local execution, and CLI integration + +## Getting Started + +### Prerequisites + +Install the required dependencies: + +```bash +pip install graphene flask flask-cors jsonpath-ng requests +``` + +### Starting the GraphQL Server + +Start the GraphQL server using the CLI: + +```bash +markitect graphql-serve +``` + +By default, this starts the server on `http://localhost:5000`. You can customize the host and port: + +```bash +markitect graphql-serve --host 0.0.0.0 --port 8080 +``` + +### Accessing the GraphQL Playground + +Once the server is running, visit `http://localhost:5000/graphql` in your browser to access the GraphQL Playground, an interactive development environment for testing queries. + +## GraphQL Schema + +### Core Types + +#### MarkdownFile +Represents a Markdown file in the MarkiTect database: + +```graphql +type MarkdownFile { + id: Int! + filename: String! + content: String + frontMatter: [FrontMatter] + frontMatterRaw: JSONString + createdAt: DateTime + wordCount: Int + lineCount: Int + hasFrontMatter: Boolean +} +``` + +#### Schema +Represents a JSON schema: + +```graphql +type Schema { + id: Int! + filename: String! + title: String + description: String + schemaContent: JSONString! + createdAt: DateTime + updatedAt: DateTime + schemaVersion: String + propertyCount: Int +} +``` + +#### AST +Represents an Abstract Syntax Tree for a Markdown file: + +```graphql +type AST { + fileId: Int + filename: String! + tree: [ASTNode] + metadata: JSONString + headingCount: Int + linkCount: Int + imageCount: Int + codeBlockCount: Int +} +``` + +#### DatabaseStats +Provides statistics about the MarkiTect database: + +```graphql +type DatabaseStats { + totalFiles: Int + totalSchemas: Int + totalSizeBytes: Int + lastUpdated: DateTime +} +``` + +#### SearchResult +Represents search results across files and schemas: + +```graphql +type SearchResult { + type: String! + score: Float + file: MarkdownFile + schema: Schema + highlight: String +} +``` + +### Query Operations + +#### Single Item Queries + +Get a specific markdown file: +```graphql +{ + markdownFile(id: 1) { + id + filename + content + wordCount + hasFrontMatter + } +} +``` + +Get a specific schema: +```graphql +{ + schema(filename: "user-schema.json") { + title + description + schemaVersion + propertyCount + } +} +``` + +Get AST for a file: +```graphql +{ + ast(filename: "document.md") { + headingCount + linkCount + tree { + type + value + level + } + } +} +``` + +#### List Queries + +Get all markdown files with pagination: +```graphql +{ + markdownFiles(limit: 10, offset: 0) { + id + filename + createdAt + hasFrontMatter + } +} +``` + +Filter files by front matter presence: +```graphql +{ + markdownFiles(hasFrontMatter: true, limit: 5) { + filename + frontMatter { + key + value + } + } +} +``` + +Get all schemas: +```graphql +{ + schemas(limit: 20) { + filename + title + description + propertyCount + } +} +``` + +#### Search Queries + +Search across all content: +```graphql +{ + search(query: "documentation", type: "all", limit: 10) { + type + score + file { + filename + content + } + schema { + title + description + } + highlight + } +} +``` + +Search only in files: +```graphql +{ + search(query: "API", type: "file", limit: 5) { + score + file { + filename + wordCount + } + highlight + } +} +``` + +#### Database Statistics + +Get database overview: +```graphql +{ + databaseStats { + totalFiles + totalSchemas + totalSizeBytes + lastUpdated + } +} +``` + +#### Advanced AST Queries + +Query AST using JSONPath expressions: +```graphql +{ + astQuery( + filename: "document.md", + jsonpath: "$.children[?(@.type=='heading')]" + ) +} +``` + +## CLI Integration + +### Available Commands + +#### graphql-serve +Start the GraphQL server: +```bash +markitect graphql-serve [OPTIONS] + +Options: + --host TEXT Host to bind to (default: 127.0.0.1) + --port INTEGER Port to bind to (default: 5000) + --debug Enable debug mode + --no-cors Disable CORS +``` + +#### graphql-query +Execute GraphQL queries from the command line: +```bash +markitect graphql-query QUERY [OPTIONS] + +Options: + --variables TEXT JSON string of query variables + --endpoint TEXT GraphQL endpoint URL + --local Execute query locally without HTTP + --format [json|yaml|table] Output format (default: json) +``` + +Examples: +```bash +# Execute a simple query locally +markitect graphql-query "{ databaseStats { totalFiles } }" --local + +# Execute query with variables +markitect graphql-query "query($limit: Int) { markdownFiles(limit: $limit) { filename } }" --variables '{"limit": 5}' --local + +# Execute query against remote server +markitect graphql-query "{ schemas { title } }" --endpoint http://localhost:5000/graphql +``` + +#### graphql-schema +Get the GraphQL schema definition: +```bash +markitect graphql-schema [OPTIONS] + +Options: + --format [sdl|json] Schema format (default: sdl) + --endpoint TEXT GraphQL endpoint URL +``` + +#### graphql-examples +Show example queries and usage: +```bash +markitect graphql-examples +``` + +## Programming API + +### Using the GraphQL Client + +```python +from markitect.graphql import GraphQLClient + +# Create a client +client = GraphQLClient("http://localhost:5000/graphql") + +# Execute a query +result = client.execute(""" +{ + markdownFiles(limit: 5) { + filename + wordCount + } +} +""") + +print(result['data']) +``` + +### Local Execution + +```python +from markitect.graphql import GraphQLClient + +# Execute queries locally without HTTP +client = GraphQLClient() +result = client.execute_local(""" +{ + databaseStats { + totalFiles + totalSchemas + } +} +""") + +print(result['data']) +``` + +### Using the Server Directly + +```python +from markitect.graphql import GraphQLServer + +# Create and start server +server = GraphQLServer(db_path="/path/to/markitect.db") +app = server.create_app() + +# Start server +server.run(host="0.0.0.0", port=8080, debug=True) +``` + +## API Endpoints + +When running the GraphQL server, the following endpoints are available: + +- `POST /graphql` - Main GraphQL endpoint for queries +- `GET /graphql` - GraphQL Playground interface +- `GET /schema` - Schema introspection +- `GET /health` - Health check endpoint + +### Health Check Response + +```json +{ + "status": "healthy", + "database": "connected", + "database_path": "/path/to/markitect.db" +} +``` + +## Error Handling + +The GraphQL interface provides comprehensive error handling: + +### Query Errors +Invalid GraphQL syntax or non-existent fields return structured errors: + +```json +{ + "data": null, + "errors": [ + { + "message": "Cannot query field 'nonexistentField' on type 'Query'" + } + ] +} +``` + +### Database Errors +Database connectivity issues are handled gracefully: + +```json +{ + "data": { + "databaseStats": null + }, + "errors": [ + { + "message": "Database connection error" + } + ] +} +``` + +## Performance Considerations + +### Pagination +Always use pagination for large datasets: + +```graphql +{ + markdownFiles(limit: 50, offset: 0) { + id + filename + } +} +``` + +### Field Selection +Only query the fields you need: + +```graphql +# Good - selective fields +{ + markdownFiles { + id + filename + } +} + +# Avoid - requesting large content fields unnecessarily +{ + markdownFiles { + id + filename + content # Only include if needed + } +} +``` + +### Search Optimization +Use specific search types when possible: + +```graphql +# Better - search only files +{ + search(query: "API", type: "file", limit: 10) { + file { + filename + } + } +} + +# Less efficient - search all types +{ + search(query: "API", type: "all", limit: 10) { + type + file { filename } + schema { title } + } +} +``` + +## Security Considerations + +### Read-Only Interface +The GraphQL interface is read-only and does not support mutations, providing safe access to MarkiTect data. + +### CORS Configuration +CORS is enabled by default for browser access. Disable with `--no-cors` if needed: + +```bash +markitect graphql-serve --no-cors +``` + +### Database Access +The interface uses the same database path configuration as the main MarkiTect CLI, respecting the `MARKITECT_DB` environment variable. + +## Troubleshooting + +### Common Issues + +#### "Flask is required" Error +Install Flask dependencies: +```bash +pip install flask flask-cors +``` + +#### "requests is required" Error +Install requests for HTTP client functionality: +```bash +pip install requests +``` + +#### Database Connection Errors +Check that your MarkiTect database exists and is accessible: +```bash +# Check database location +echo $MARKITECT_DB + +# Verify database exists +ls -la ~/.markitect/markitect.db +``` + +#### GraphQL Syntax Errors +Use the GraphQL Playground at `http://localhost:5000/graphql` to validate your queries with real-time syntax checking and auto-completion. + +## Examples + +### Complete Data Export +Export all markdown files with metadata: + +```graphql +{ + markdownFiles { + id + filename + content + createdAt + wordCount + lineCount + hasFrontMatter + frontMatter { + key + value + } + } +} +``` + +### Schema Analysis +Analyze all schemas in the database: + +```graphql +{ + schemas { + filename + title + description + schemaVersion + propertyCount + schemaContent + } +} +``` + +### Content Discovery +Find all documents containing specific terms: + +```graphql +{ + search(query: "authentication security", type: "all", limit: 20) { + type + score + file { + filename + wordCount + hasFrontMatter + } + schema { + title + description + } + highlight + } +} +``` + +### Database Overview +Get a complete overview of your MarkiTect database: + +```graphql +{ + databaseStats { + totalFiles + totalSchemas + totalSizeBytes + lastUpdated + } + recentFiles: markdownFiles(limit: 5) { + filename + createdAt + } + recentSchemas: schemas(limit: 5) { + filename + title + createdAt + } +} +``` + +## Integration Examples + +### With JavaScript/TypeScript + +```typescript +interface DatabaseStats { + totalFiles: number; + totalSchemas: number; + totalSizeBytes: number; + lastUpdated: string; +} + +async function getStats(): Promise { + const response = await fetch('http://localhost:5000/graphql', { + method: 'POST', + headers: { + 'Content-Type': 'application/json', + }, + body: JSON.stringify({ + query: ` + { + databaseStats { + totalFiles + totalSchemas + totalSizeBytes + lastUpdated + } + } + ` + }) + }); + + const { data } = await response.json(); + return data.databaseStats; +} +``` + +### With Python + +```python +import requests +from typing import List, Dict, Any + +def search_content(query: str, limit: int = 10) -> List[Dict[str, Any]]: + """Search for content in MarkiTect database.""" + + response = requests.post('http://localhost:5000/graphql', json={ + 'query': ''' + query SearchContent($query: String!, $limit: Int!) { + search(query: $query, type: "all", limit: $limit) { + type + score + file { + filename + wordCount + } + schema { + title + description + } + highlight + } + } + ''', + 'variables': { + 'query': query, + 'limit': limit + } + }) + + return response.json()['data']['search'] + +# Usage +results = search_content("API documentation", limit=5) +for result in results: + print(f"Found {result['type']}: {result['highlight']}") +``` + +This GraphQL interface provides a powerful, flexible way to access and query MarkiTect data, enabling rich integrations and applications built on top of your Markdown content management system. \ No
