- title: Serverless integrations for Feral
  description:
    Feral is a Typelevel library for building serverless functions that currently supports AWS Lambda and Google Cloud Run Functions. We want to add support for more types of serverless events and more cloud providers.
  prereqs: Scala, ideally experience with serverless
  difficulty: Medium.

- title: Native I/O backend for FS2 JVM
  description:
    FS2 on the JVM currently implements its networking API using JDK NIO. Unfortunately this indirection incurs a non-trivial performance penalty. We want to replace the use of JDK NIO with direct calls to system I/O APIs such as `epoll` and `kqueue`.
  prereqs: Scala, ability to read C
  difficulty: Medium.

- title: FS2 Connection API
  description:
    TCP-based protocols are common (e.g. HTTP, Postgres, Redis) and are implemented by clients to interface with these services (e.g. Ember, Skunk, Rediculous). The goal of this project is to create a "connection" API that supports pooling, error conditions, and metrics and can be shared by all of our client libraries.
  prereqs: Scala, ideally some knowledge of networking
  difficulty: Hard.

- title: Web Components for Calico
  description:
    Calico is a reactive UI library built with Cats Effect and FS2. Web Components are a standard for creating framework-agnostic, reusable UI elements. The goal of this project is to enable Calico users to access the vast array of web components available by improving its DSL and code-generation.
  prereqs: Scala, ideally experience with Web APIs
  difficulty: Medium.

- title: Upgrade sbt-typelevel to sbt 2
  description:
    sbt-typelevel is a plugin for sbt, the Scala build tool, used by hundreds of open source and enterprise projects. sbt 2 is in the final stages of development. We want to upgrade sbt-typelevel to sbt 2 and adopt its new features, such as "project matrix" for cross-building.
  prereqs: Scala
  difficulty: Medium.

- title: Refresh Davenverse projects
  description:
    The Davenverse is a collection of several popular Typelevel libraries, including Mules and cats-scalacheck. Unfortunately, we have fallen behind on their maintenance. We want to move these libraries under the Typelevel org, refresh their build tooling, and bring them up-to-date to ensure their longevity.
  prereqs: Scala
  difficulty: Medium.
  length: medium

- title: Cats Effect & FS2 on Wasm/WASI
  description:
    Web Assembly and its System Interface are emerging technologies for deploying secure, modular applications. The goal of this project is to prototype porting the Cats Effect runtime and FS2 streaming I/O to the Wasm/WASI platform, also possibly generating feedback for the Scala WASM and WASI teams.
  prereqs: Scala, ideally some experience with Wasm/WASI
  difficulty: Hard. Wasm/WASI support in Scala is experimental.

- title: A faster immutable list datatype
  description:
    Immutable linked lists are a core datatype in functional programming languages. The goal of this project is to explore implementing a list-like datatype with enhanced performance. Along the way, you will learn about immutable datatypes, Cats typeclasses, and mechanical sympathy.
  prereqs: Interest in functional programming
  difficulty: Medium. This is a good project for beginners!
