Open‑Source Architecture Tools: mpvue, Walle, SQLAdvisor, Leaf, and Robust

mpvue is a Vue.js based front‑end framework for developing mini‑programs on platforms such as WeChat, Baidu, Toutiao, and Alipay, providing component‑based development, full Vue.js experience, Vuex data management, webpack build, npm support, and H5‑to‑mini‑program compilation.

Walle (瓦力) is a new‑generation channel‑package tool for Android Signature V2, adding custom channel information to the APK Signature Block; it can be used as a standalone CLI or deployed on an HTTP server to generate channel packages on‑the‑fly.

Configuration in the project’s build.gradle adds the Walle Gradle plugin:

buildscript {
    dependencies {
        classpath 'com.meituan.android.walle:plugin:1.1.7'
    }
}
apply plugin: 'walle'
dependencies {
    compile 'com.meituan.android.walle:library:1.1.7'
}
walle {
    apkOutputFolder = new File("${project.buildDir}/outputs/channels")
    apkFileNameFormat = '${appName}-${packageName}-${channel}-${buildType}-v${versionName}-${versionCode}-${buildTime}.apk'
    channelFile = new File("${project.getProjectDir()}/channel")
}

SQLAdvisor, developed by Meituan‑Dianping’s DBA team, parses MySQL statements and provides index‑optimization suggestions based on WHERE clauses, aggregation, and multi‑table joins.

Leaf is a distributed ID generation service offering both segment and Snowflake modes. Its configuration resides in leaf-server/src/main/resources/leaf.properties , with options such as leaf.segment.enable , leaf.snowflake.enable , JDBC settings, and Zookeeper address.

Robust is a next‑generation hot‑update system compatible with Android 2.3‑10, enabling real‑time patch application without restart, supporting method‑level fixes, class additions, and ProGuard obfuscation.

To use Robust, add the following to the app’s build.gradle :

apply plugin: 'com.android.application'
apply plugin: 'robust'
compile 'com.meituan.robust:robust:0.4.99'

And to the root build.gradle :

buildscript {
    repositories { jcenter() }
    dependencies {
        classpath 'com.meituan.robust:gradle-plugin:0.4.99'
        classpath 'com.meituan.robust:auto-patch-plugin:0.4.99'
    }
}

All projects are open‑source on GitHub: mpvue, Walle, SQLAdvisor, Leaf, and Robust.
