Feature Request

Background

As microsoft-cognitiveservices-speech-sdk has stable release for Direct Line Speech, we should converge all versions used in Web Chat to a single one, reducing out footprint.

Marked are 3 copies of microsoft-cognitiveservices-speech-sdk in webchat.js.

Update on 2020-03-26

Despite converging, Webpack doesn't dedupe packages based on their name + version.

For example, we have:

• packages/bundle/node_modules/[email protected]
• packages/directlinespeech/node_modules/[email protected]

Both of them are @1.10.1, but since their paths are different, Webpack will bundle them separately in the bundle. Every microsoft-cognitiveservices-speech-sdk will take up about 250-300 KB after minified before gzip.

Short-term solution

What we could do temporarily is to use resolve.alias to alias microsoft-cognitiveservices-speech-sdk together. But it need to be elaborated if we are using tree-shaking, like below:

  resolve: {
    alias: {
+     'microsoft-cognitiveservices-speech-sdk/distrib/lib/src/sdk/Audio/AudioConfig': resolve(__dirname, 'node_modules/microsoft-cognitiveservices-speech-sdk/distrib/lib/src/sdk/Audio/AudioConfig.js'),
+     'microsoft-cognitiveservices-speech-sdk/distrib/lib/microsoft.cognitiveservices.speech.sdk': resolve(__dirname, 'node_modules/microsoft-cognitiveservices-speech-sdk/distrib/lib/microsoft.cognitiveservices.speech.sdk.js'),
+     'microsoft-cognitiveservices-speech-sdk': resolve(__dirname, 'node_modules/microsoft-cognitiveservices-speech-sdk/distrib/lib/microsoft.cognitiveservices.speech.sdk.js'),
      react: resolve(__dirname, 'node_modules/isomorphic-react/dist/react.js'),
      'react-dom': resolve(__dirname, 'node_modules/isomorphic-react-dom/dist/react-dom.js')
    },

Long-term solution

Since we cannot hoist packages due to technical problems, what we could do for long-term is to write a ResolverPlugin for Webpack that will do dedupe based on package name and version numbers.
