--- title: Create development builds with EAS Workflows sidebar_title: Create development builds description: Learn how to create development builds with EAS Workflows. hideTOC: true --- [Development builds](/develop/development-builds/introduction/) are specialized builds of your project that include Expo's developer tools. These types of builds include all native dependencies inside your project, enabling you to run a production-like build of your project on a simulator, emulator, or a physical device. This workflow allows you to create development builds for each platform and for both physical devices, Android emulators, and iOS simulators, which your team can access with `eas build:dev`. ## Get started <Requirement number={1} title="Set up your environment"> To get started, you'll need to configure your project and devices to build and run development builds. Learn how to set up your environment for development builds with the following guides: </Requirement> <Requirement number={2} title="Create build profiles"> After you've configured your project and devices, add the following build profiles to your **eas.json** file. ```json eas.json { "build": { "development": { "developmentClient": true, "distribution": "internal" }, "development-simulator": { "developmentClient": true, "distribution": "internal", "ios": { "simulator": true } } } } ``` </Requirement> The following workflow creates a build for each platform and for both physical devices, Android emulators, and iOS simulators. They all will run in parallel. ```yaml .eas/workflows/create-development-builds.yml name: Create development builds jobs: android_development_build: name: Build Android type: build params: platform: android profile: development ios_device_development_build: name: Build iOS device type: build params: platform: ios profile: development ios_simulator_development_build: name: Build iOS simulator type: build params: platform: ios profile: development-simulator ``` Run the above workflow with:
