Título typed data has 47 digits Título amount must be less than R$ 100 mi (100 millions reais) Título currency must be BRL (Brazilian Real). It's considered that due date (data de vencimento) is always at or before 21st - February - 2025

I used a default Node docker container to avoid environment issues.
"express": "~4.17.1",
"moment": "^2.24.0",
"chai": "~4.2.0",
"mocha": "~6.1.4",
Single endpoint.
Expects a POST request with form-data field called typedData
Sample request:
POST HTTP/1.1
Host: localhost:8080?
Content-Type: application/x-www-form-urlencoded
User-Agent: PostmanRuntime/7.15.0
Cache-Control: no-cache

typedData=23792.40308+90000.871286+57003.613700+4+79460000122399
Sample response (status 200)
{
"validData": true,
"amount": 1223.99,
"dueDate": "10/07/2019",
"barcode": "23794794600001223992403090000871285700361370",
"message": "Titulo successfully verified."
}
I've used chai, mocha and supertest modules.
npm run test
or
npm run coverage
docker build -t slipchecker .
docker create --name slipchecker -p 8080:8080 slipchecker
docker start slipchecker
Inside app folder:
npm install
npm run start
As a MVP some aspects are missing:
- Título amount more or equal to R$ 100 mi (100 millions reais) .
- Título currency different from BRL (Brazilian Real).
- Título due date at or after 22nd - February - 2025.
