How to use PostgreSQL with Haskell: hasql

1. hasql-transaction

   1 1 13 5.5 Haskell

   A composable abstraction over retriable transactions for Hasql

   

   Hasql is an ecosystem of libraries. To keep it simple, let’s limit ourselves to core hasql, hasql-transaction, and hasql-th. We’re using hasql 1.6.3.2 published in 2023.

2. InfluxDB

   www.influxdata.com featured

   InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

   

3. profunctors

   2 4 70 4.2 Haskell

   Haskell 98 Profunctors

   

   We’ll also use contravariant-extras, vector, profunctors, and tuple packages to make a few things tidier (this isn’t required; it’s all copy-paste anyway).

4. hasql-pool

   3 1 18 5.8 Haskell

   A pool of connections for Hasql

   

   In reality/production, we should probably use hasql-pool to work with a pool of connections.

5. contravariant-extras

   4 1 3 5.5 Haskell

   Extras for the "contravariant" package

   

   We’ll also use contravariant-extras, vector, profunctors, and tuple packages to make a few things tidier (this isn’t required; it’s all copy-paste anyway).

6. hasql-th

   5 4 113 5.6 Haskell

   Template Haskell utilities for Hasql

   

   Hasql is an ecosystem of libraries. To keep it simple, let’s limit ourselves to core hasql, hasql-transaction, and hasql-th. We’re using hasql 1.6.3.2 published in 2023.
