How to set up TLS encryption with deno_mysql?

Configure the TLS mode (e.g., VERIFY_IDENTITY) and provide custom CA certificates in the tls options when connecting, as shown in the README's TLS section. This ensures secure database communication but requires manual certificate handling.

deno_mysql vs Node.js mysql2 driver for performance?

deno_mysql is optimized for Deno's async runtime and offers features like iterator-based execution for large results, but Node.js mysql2 might have more mature optimizations and a larger ecosystem. For Deno projects, deno_mysql is the best choice despite potential performance trade-offs in cross-runtime comparisons.

How to handle transactions in deno_mysql?

Use the transaction() method with a callback function that takes a connection object, allowing you to execute queries within a transaction block. The README shows an example with insert and select operations, ensuring ACID compliance.

Can deno_mysql work with MariaDB without changes?

Yes, deno_mysql is compatible with MariaDB using the same API and connection options, as it's designed for MySQL-compatible databases. No additional configuration is needed beyond standard setup.

How to disable logging in deno_mysql?

Call the configLogger() function with enable: false, as mentioned in the README's logging section. This stops console output for cleaner application logs in production.

What's the difference between query() and execute() methods?

query() returns all rows as an array, while execute() can return either an array or an iterator for streaming. Use execute() with iterator: true for large result sets to improve memory efficiency, as advised in the documentation.

deno_mysql — MySQL Driver for Deno

What is deno_mysql?

deno_mysql is a MySQL and MariaDB database driver specifically built for the Deno runtime. It provides a secure and efficient way for Deno applications to interact with MySQL-compatible databases, offering features like connection pooling, TLS encryption, and transaction support. The driver enables developers to perform all standard database operations while adhering to Deno's security model.

Target Audience

Deno developers building backend applications, APIs, or services that require MySQL/MariaDB database connectivity. It's particularly useful for teams adopting Deno for new projects or migrating Node.js applications to Deno.

Value Proposition

Developers choose deno_mysql because it's the most mature and feature-complete MySQL driver for Deno, offering production-ready capabilities like connection pooling and TLS support. Its TypeScript-first design and alignment with Deno's security model make it a reliable choice for building secure database-driven applications in Deno.

MySQL driver for Deno

Use Cases

Best For

Building Deno backend services that require MySQL database connectivity
Migrating Node.js applications with MySQL dependencies to Deno
Developing secure Deno APIs with encrypted database connections
Creating data-intensive Deno applications with connection pooling needs
Implementing transactional data operations in Deno applications
Working with large MySQL result sets efficiently in Deno

Not Ideal For

Applications using non-MySQL databases like PostgreSQL or MongoDB
Teams wanting built-in ORM with model definitions and automatic relationship handling
Projects that must run in Node.js environments or depend heavily on npm packages
Legacy systems requiring synchronous database operations rather than async-first patterns

Pros & Cons

Pros

Secure TLS Integration

Supports configurable TLS modes including identity verification and custom certificate authorities, ensuring encrypted database communication as per Deno's security model.

Efficient Connection Pooling

Built-in pool management with adjustable size optimizes resource usage and performance for concurrent operations, demonstrated in the connect pool example.

Flexible Result Handling

Offers both standard query execution and iterator-based methods for large datasets, allowing efficient streaming of rows to prevent memory overload.

Comprehensive Transaction Support

Provides full ACID transaction capabilities with a clean, promise-based API, enabling reliable data integrity in complex operations.

Cons

Deno-Only Runtime Limitation

Exclusively tied to Deno, making it incompatible with Node.js projects and limiting use in environments where Deno adoption is low.

Limited Ecosystem Maturity

Compared to Node.js MySQL drivers, it has fewer community resources, third-party tools, and integrations, which can hinder advanced development.

Manual TLS Setup Complexity

Requires explicit configuration for custom certificates, such as reading PEM files, adding overhead compared to drivers with automated certificate management.
