## Introduction
I have a deep passion for Scala and Functional Programming, although my professional work predominantly involves
JavaScript and TypeScript on Node.js.
To bridge this gap, I initiated this project to handle various one-time or recurring tasks. More importantly,
this project serves as a platform for me to learn and practice Scala 3, delve into Functional Programming with libraries
like Cats and ZIO, and explore other Scala libraries.
**Topics**:
- [Scala 3](https://scala-lang.org/)
- [Skunk](https://github.com/typelevel/skunk): a functional PostgreSQL client for Scala.
- [PureConfig](https://github.com/pureconfig/pureconfig): a Scala library for loading configuration files.
- [PostgreSQL](https://www.postgresql.org/): a powerful, open source object-relational database system.
- [cats](https://typelevel.org/cats/): a library that provides abstractions for functional programming in Scala.
- [cats-effect](https://typelevel.org/cats-effect/): a library that provides abstractions for effectful programming in
Scala.
- [circe](https://circe.github.io/circe/): a JSON library for Scala.
## Apps
### RefundApp
**Run**:
```shell
auto/dev io.daniel.apps.RefundApp
auto/prod io.daniel.apps.RefundApp
```
### ClubTransfer
Read a CSV file, then send emails using AWS SES client.
How to run the application:
- changeAwsProfileToProd
- change the `paymentType` to `PIF` or `DD`
- put the corresponding csv file in the `src/main/resources` folder, file name should be `pif_club_transfer.json` or
`dd_club_transfer.json`
- run the application: auto/prod io.daniel.apps.ClubTransfer
- can test by changing #185 to `toDaniel` email
**Run**:
```shell
auto/dev io.daniel.apps.ClubTransfer
auto/prod io.daniel.apps.ClubTransfer
```
### FixDuplicateEmails
Read a plain text file with emails, query and update Dynamodb data using AWS SDK.
```shell
auto/dev io.daniel.apps.FixDuplicateEmails
auto/prod io.daniel.apps.FixDuplicateEmails
```
## Setup
Start the local PostgreSQL database using Docker:
```shell
docker compose up
```
## Trouble Shooting
### How to specify the application to run
- Setting the mainClass in `build.sbt`
```sbt
Compile / mainClass := Some("io.daniel.Main")
Compile / mainClass := Some("io.daniel.apps.RefundApp")
```
- Using the `run` task with the `--main` option
```shell
sbt "runMain io.daniel.apps.FixDuplicateEmails"
```
### Secrets Manager can't find the specified secret.
> Secrets Manager can't find the specified secret. (Service: SecretsManager, Status Code: 400, Request ID:
> aab88d0e-ca3b-461a-8a6f-21371846fc63)
**Options**:
- Option 1: add environment variable `AWS_PROFILE=prod` to Intellij Idea Run/Debug configuration.
- Option 2: run on the command line: `AWS_PROFILE=prod auto/prod io.daniel.apps.ClubTransfer`
