mpx-jest

Jest transformer for Mpx single-file components. The current implementation is aligned with @mpxjs/webpack-plugin 2.11.x.

Usage

Configure the transformer in jest.config.js:

module.exports = {
  transform: {
    '^.+\\.mpx$': ['@mpxjs/mpx-jest', {
      mode: 'wx',
      srcMode: 'wx'
    }]
  }
}

The transformer defaults to component semantics, detects app.mpx automatically, and supports page matching through Mpx-style conditions:

module.exports = {
  transform: {
    '^.+\\.mpx$': ['@mpxjs/mpx-jest', {
      mode: 'wx',
      srcMode: 'wx',
      pageRules: {
        include: /[\\/]pages[\\/]/
      }
    }]
  }
}

Supported transformer options include mode, srcMode, env, defs, ctorType, pageRules, componentRules, externalClasses, autoScopeRules, autoVirtualHostRules, checkUsingComponentsRules, forceProxyEventRules, optimizeRenderRules, globalComponents, globalComponentsInfo, and pathHashMode.

The transformer handles TypeScript, Mpx <script setup>, external template/JSON blocks, inline or external WXS modules, optional chaining helpers, JSON platform conversion, component metadata, and coverage source maps.
