A Scala and ZIO playground which happens to be an auth service.

• ./sbt app/run

• brew cask install java11
• brew install cassandra (will also install cqlsh)
• Cassandra doesn't work with java 14 (we are using java 11)
• Some jvm options doesn't work so we have to edit /usr/local/etc/cassandra/jvm.options
• Launch with cassandra -f
• Stop with ctrl c or ps to get the PID and then kill <PID>
• Default host and port is 127.0.0.1:9042
• cqlsh will connect there by default
• CREATE KEYSPACE IF NOT EXISTS thewho_dummy WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
• Edit app/Main and build.sbt to use cassandra instead of in memory db

• Edit app/Main and build.sbt to use http4s instead of finch. See server/http4s/Server

• Edit app/Main and build.sbt to use postgres instead of in memory db
• Add 127.0.0.1 postgres to your /etc/hosts file
• docker-compose up
• docker exec -it postgres bash
• psql -d postgres -U postgres

Credential:                    { id: String, secret: String }
CredentialSecretUpdateRequest: { oldCredential: Credential, newSecret: String }
TokenResponse:                 { token: String }
UserCredentialIdRequest:       { token: String }
UserCredentialIdResponse:      { credentialId: String }

• ./sbt gatling/gatling:test

• ./sbt test

• To generate key pairs:

openssl genrsa -out private.pem 1024
openssl rsa -in private.pem -pubout -outform PEM -out public_key.pem
openssl pkcs8 -topk8 -inform PEM -in private.pem -out private_key.pem -nocrypt

the las line is needed because of the format java uses.

• Sending json thru httpie:

echo '{ "id": "Salvador", "secret": "Dalí" }' | http POST http://127.0.0.1:8080/signup -v
echo '{ "oldCredential": { "id": "Salvador", "secret": "Dalí" }, "newSecret": "lanadanisman" }' | http POST http://127.0.0.1:8080/change-password -v
