--- visibility: public --- # Scala **repo:** [lauris/awesome-scala](https://github.com/lauris/awesome-scala) **category:** [[programming-languages|Programming Languages]] **related:** [[apache-spark|Apache Spark]] · [[haskell|Haskell]] · [[elixir|Elixir]] · [[erlang|Erlang]] --- Awesome Scala [](https://github.com/sindresorhus/awesome) ============= A community driven list of useful Scala libraries, frameworks and software. This is not a catalog of all the libraries, just a starting point for your explorations. Inspired by [awesome-python](https://github.com/vinta/awesome-python). Other amazingly awesome lists can be found in the [awesome-awesomeness](https://github.com/bayandin/awesome-awesomeness) list. Also awesome is [Scaladex](https://index.scala-lang.org/), the searchable, tagged, and centralized index of Scala libraries. Projects with over 500 stargazers are in bold. ## Contributing Your contributions are always welcome! Please submit a pull request or create an issue to add a new framework, library or software to the list. Do not submit a project that hasn’t been updated in the past 6 months or is not awesome. Don't modify `README.md` in your pull request. It is automatically generated. Modify `template.md` instead. ## Table of Contents - [Learning Scala](#[learning](/@harrisonqian/awesome/wiki/programming-languages/learning)-scala) - [Projects](#projects) - [Android](#android) - [Archive and Compression](#archive-and-compression) - [Artificial Intelligence](#artificial-intelligence) - [Authentication](#authentication) - [Authorization](#authorization) - [Big Data](#big-data) - [Command Line Interfaces](#command-line-interfaces) - [Cryptography](#cryptography) - [CSV](#csv) - [Data Binding and Validation](#data-binding-and-validation) - [Database](#database) - [DevOps](#devops) - [Distributed Systems](#distributed-systems) - [Extensions](#extensions) - [Functional Reactive Programming](#functional-reactive-programming) - [Geospatial](#geospatial) - [Graphical User Interfaces](#graphical-user-interfaces) - [HTTP](#http) - [i18n](#i18n) - [Image processing and image analysis](#image-processing-and-image-analysis) - [JavaScript](#javascript) - [JSON](#json) - [Markdown](#markdown) - [Metrics and Monitoring](#metrics-and-monitoring) - [Misc](#misc) - [Modularization and Dependency Injection](#modularization-and-dependency-injection) - [Parsing](#parsing) - [Reactive Web Frameworks](#reactive-web-frameworks) - [Sbt plugins](#sbt-plugins) - [Science and Data Analysis](#science-and-data-analysis) - [Scheduling](#scheduling) - [Semantic Web](#semantic-web) - [Serialization](#serialization) - [Templating](#templating) - [Testing](#testing) - [Tools](#tools) - [Web Frameworks](#web-frameworks) - [XML / HTML](#xml--html) - [YAML](#yaml) - [Learning Scala](#[learning](/@harrisonqian/awesome/wiki/programming-languages/learning)-scala) - [Books](#books) - [Exercises](#exercises) - [Tutorials and courses](#[tutorials](/@harrisonqian/awesome/wiki/computer-science/tutorials)-and-courses) - [Commercial courses](#commercial-courses) - [Community members' blogs](#community-members-blogs) - [Company Blogs](#company-blogs) - [Podcasts](#podcasts) - [Contributing](#contributing) ### Archive and Compression Name | Description | GitHub Activity ---- | ----------- | --------------- ### Artificial Intelligence Name | Description | GitHub Activity ---- | ----------- | --------------- ### Database *Database access libraries in Scala.* Name | Description | GitHub Activity ---- | ----------- | --------------- [akka-persistence-gcp-datastore](https://github.com/innFactory/akka-persistence-gcp-datastore) | akka-persistence-gcp-datastore is a journal and snapshot store plugin for akka-persistence using google cloud firestore in datastore mode. | [anorm](https://github.com/playframework/anorm) | The Anorm database library | [clickhouse-scala-client](https://github.com/crobox/clickhouse-scala-client) | Clickhouse Scala Client with Reactive Streams support | [couchbase-jvm-clients](https://github.com/couchbase/couchbase-jvm-clients) | The Couchbase Monorepo for JVM Clients: Java, Scala, io-core… | [**doobie**](https://github.com/typelevel/doobie) | Functional JDBC layer for Scala. | [**elastic4s**](https://github.com/Philippus/elastic4s) | 🔍 Elasticsearch Scala Client - Reactive, Non Blocking, Type Safe, HTTP Client | [etcd4s](https://github.com/mingchuno/etcd4s) | Scala etcd client implementing V3 APIs | [laserdisc](https://github.com/laserdisc-io/laserdisc) | A Future-free Fs2 native pure FP Redis client | [mysql-binlog-stream](https://github.com/laserdisc-io/mysql-binlog-stream) | None | [neotypes](https://github.com/neotypes/neotypes) | Scala lightweight, type-safe, asynchronous driver for neo4j | [pulsar4s](https://github.com/CleverCloud/pulsar4s) | Idiomatic, typesafe, and reactive Scala client for Apache Pulsar | [**zio-quill**](https://github.com/zio/zio-quill) | Compile-time Language Integrated Queries for Scala | [**ReactiveMongo**](https://github.com/ReactiveMongo/ReactiveMongo) | :leaves: Non-blocking, Reactive MongoDB Driver for Scala | [**rediscala**](https://github.com/etaty/rediscala) | Non-blocking, Reactive Redis driver for Scala (with Sentinel support) | [relate](https://github.com/lucidsoftware/relate) | Performant database access in Scala | [**sangria**](https://github.com/sangria-graphql/sangria) | Scala GraphQL implementation | [scala-forklift](https://github.com/lastland/scala-forklift) | Type-safe data migration tool for Slick, Git and beyond. | [scalarelational](https://github.com/outr/scalarelational) | Type-Safe framework for defining, modifying, and querying SQL databases | [**scalikejdbc**](https://github.com/scalikejdbc/scalikejdbc) | A tidy SQL-based DB access library for Scala developers.
