Simple example of rails application for API using some dry-rb gems like:
- dry-validation
- dry-monads
- dry-matcher
- dry-struct
Run in the console:
rails s
Next you can play with it using curl command, examples:
- with valid params
curl -d '{"first_name":"John", "last_name":"Doe"}' -H "Content-Type: application/json" -H "Authorization: Bearer XXX" -X POST http://localhost:3000/tokens.json | jq
{
"first_name": "John",
"last_name": "Doe"
}
- with invalid params
curl -d '{"last_name":"Doe"}' -H "Content-Type: application/json" -H "Authorization: Bearer XXX" -X POST http://localhost:3000/tokens.json | jq
{
"errors": {
"first_name": [
"is missing"
]
}
}
- with missing authorization header
curl -v -d '{"first_name":"John", "last_name":"Doe"}' -H "Content-Type: application/json" -X POST http://localhost:3000/tokens.json | jq
