Effect Examples

Create Effect App

The easiest way to get started with Effect is by using create-effect-app.

This CLI tool enables you to quickly bootstrap a project with Effect, with everything pre-configured for you.

You can create a new project using one of our project templates or by using one of the official Effect examples.

See the documentation for more information.

Examples

This repository contains examples which can be used to understand how to use Effect. You can also clone an example to your local machine via the create-effect-app CLI tool.

The available examples include:

Name	Description
http-server	An HTTP server built with Effect complete with authentication and authorization.

Templates

This repository contains templates which can be used to quickly bootstrap a new project with Effect via the create-effect-app CLI tool.

These templates were developed to mirror the project configuration recommneded by the Effect core team and are thus somewhat opinionated.

Basic

The basic template is meant to serve as the foundation for building a single package or library with Effect.

The template features:

• Pre-configured build pipeline which supports both ESM and CJS
• Pre-configured test pipeline via vitest
• Pre-configured TypeScript configuration
• ESLint & Dprint for linting and formatting, respectively (optional)
• Nix to provide a consistent development shell (optional)
• Changesets for version management and publication (optional)
• The Effect team's recommended GitHub Actions (optional)

For more information, see the template README.

Monorepo

The monorepo template is meant to serve as the foundation for building multiple packages or applications with Effect.

The template features everything included with the basic template in addition to:

• Pre-configured TypeScript path aliases and project references to support package interdependencies

For more information, see the template README.

CLI

The cli template is meant to serve as the foundation for building a command-line application with Effect CLI.

The template features everything included with the basic template, except with a different build pipeline:

• Pre-configured build pipeline is via tsup to support bundling to a single file
