Question 1

How do I connect to PostgreSQL with deno-postgres?

Accepted Answer

Import the Client from JSR, configure it with connection details, and call connect() with appropriate Deno permissions like --allow-net. The README provides a clear example using template literals for queries.

Question 2

Is deno-postgres ready for production use?

Accepted Answer

It's reasonably stable but pre-1.0, with breaking changes expected. For production, assess risk tolerance—use it if you can handle updates, but avoid for critical systems requiring absolute API stability.

Question 3

deno-postgres vs node-postgres: which should I choose?

Accepted Answer

Choose deno-postgres for Deno-specific projects due to native integration and security; node-postgres is better for Node.js ecosystems or cross-runtime needs, as it's more mature with a larger community.

Question 4

What permissions does deno-postgres need in Deno?

Accepted Answer

It requires network access (--allow-net) to connect to PostgreSQL, and possibly --allow-read for config files. Always review Deno's security flags based on your deployment environment.

Question 5

How to handle transactions with deno-postgres?

Accepted Answer

Use the client's transaction methods or manual BEGIN/COMMIT queries via queryArray or queryObject. The documentation likely covers this, but check for examples on the project website.

Question 6

Can I use deno-postgres with Deno Deploy?

Accepted Answer

Potentially, but verify network compatibility and PostgreSQL accessibility, as Deno Deploy has limitations. The driver supports modern Deno versions, but test thoroughly in serverless contexts.
