It’s still work in progress, but you can take it for a test drive!

deno-postgres is being developed based on excellent work of node-postgres and pq.

To Do:

  • connecting to database
  • password handling:
    • cleartext
    • MD5
  • DSN style connection parameters
  • reading connection parameters from environmental variables
  • termination of connection
  • simple queries (no arguments)
  • parsing Postgres data types to native TS types
  • row description
  • parametrized queries
  • connection pooling
  • parsing error response
  • SSL (waiting for Deno to support TLS)
  • tests, tests, tests
