  • dry-validation

    Validation library with type-safe schemas and rules

    I wouldn't add any type validations in my first version. Should they be needed I would use https://github.com/dry-rb/dry-validation.

  • rbs

    Type Signature for Ruby

    Numeric? and Numeric | nil are RBS syntax, but RBS goes in a separate file, not in your Ruby code. (I have RBS, because it comes with Ruby 3.0, but I don't use RBS.)

  • InfluxDB

    Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.
