1) Intro

RapidReader is a Compose Multiplatform app for focused reading using RSVP (Rapid Serial Visual Presentation). You can start from a PDF file, a link, or pasted text, and the app presents the content word-by-word for distraction-free reading across platforms.

2) Targets supported

• Android (Compose)
• Desktop (JVM): macOS (DMG), Windows (MSI), Linux (DEB)
• iOS: device (arm64) + simulator (arm64)
• Web: Kotlin/Wasm + Kotlin/JS browser targets

3) Configuration guide

Prerequisites

• Gradle wrapper: use ./gradlew (or .\gradlew.bat on Windows)
• JDK:
  • For day-to-day development, a standard JDK is fine.
  • For Desktop packaging, you need a full JDK that includes jpackage. If packaging fails, set org.gradle.java.home in gradle.properties to that JDK’s home.

Quick build commands (recommended)

• Desktop installers (copies into dist/desktop/)

  • macOS:

    ./gradlew :composeApp:exportDesktopMac

  • Windows:

    .\gradlew.bat :composeApp:exportDesktopWindows

  • Linux:

    ./gradlew :composeApp:exportDesktopLinux

• Desktop (run locally)

  ./gradlew :composeApp:run

• Android (APK)

  ./gradlew :composeApp:assembleDebug

• Web dev server

  • Wasm (modern browsers):

    ./gradlew :composeApp:wasmJsBrowserDevelopmentRun

  • JS (wider browser support):

    ./gradlew :composeApp:jsBrowserDevelopmentRun

Run targets

• Android

  ./gradlew :composeApp:assembleDebug

• Desktop (run)

  ./gradlew :composeApp:run

• Desktop (package installers)

  # Depending on your Compose Desktop plugin version, these may be either:
  # - packageDmg / packageMsi / packageDeb
  # - packageReleaseDmg / packageReleaseMsi / packageReleaseDeb
  ./gradlew :composeApp:packageDmg
  ./gradlew :composeApp:packageMsi
  ./gradlew :composeApp:packageDeb

  The recommended tasks above (exportDesktopMac/Windows/Linux) will build + copy the resulting installer into dist/desktop/ with consistent filenames:

  • dist/desktop/RapidReader-1.0.0-mac.dmg
  • dist/desktop/RapidReader-1.0.0-windows.msi
  • dist/desktop/RapidReader-1.0.0-linux.deb

• Web (Wasm — modern browsers)

  ./gradlew :composeApp:wasmJsBrowserDevelopmentRun

• Web (JS — wider browser support)

  ./gradlew :composeApp:jsBrowserDevelopmentRun

• iOS

  • Open iosApp in Xcode and run the iOS app target.
