convex-functions

Master Convex functions including queries, mutations, actions, and HTTP endpoints with proper validation, error handling, and runtime considerations. All examples in this skill comply with @convex-dev/eslint-plugin rules: See the Code Quality section in convex-best-practices for linting setup. Before implementing, do not assume; fetch the latest documentation: Queries are reactive, cached, and read-only: Mutations modify the database and are transactional: Actions can call external APIs but have no direct database access: HTTP actions handle webhooks and external requests: Use internal functions for sensitive operations: Schedule functions to run later: - Object syntax with handler property - Argument validators on all functions - Explicit table names in database operations - Primary: - Query Functions: - Mutation Functions: - Actions: - HTTP Actions: - For broader context: - Never run npx convex deploy unless explicitly instructed - Never run any git commands unless explicitly instructed - Always define args and returns validators - Use queries for read operations (they are cached and reactive) - Use mutations for write operations (they are transactional) - Use actions only when calling external APIs - Use internal functions for sensitive operations - Add "use node"; at the top of action files using Node.js APIs - Handle errors with ConvexError for user-facing messages -...
