Migration Guide

SMP follows semver. This guide should help with upgrading major versions.

v0 → v1

If Using Static Constructor

If you're using the SpeedMeasurePlugin.wrapPlugins(plugins, options) static method, then

• remove all .wrapPlugins calls
• instantiate an smp
• call smp.wrap on your entire config

e.g.

// v0
const webpackConfig = {
  plugins: SpeedMeasurePlugin.wrapPlugins(
    {
      FooPlugin: new FooPlugin(),
    },
    smpOptions
  ),
};

// v1
const smp = new SpeedMeasurePlugin(smpOptions);
const webpackConfig = smp.wrap({
  plugins: [new FooPlugin()],
});

If Using smp Instance

If you're using the smp.wrapPlugins(plugins) method, then

• remove all .wrapPlugins calls
• call smp.wrap on your entire config

e.g.

// v0
const smp = new SpeedMeasurePlugin(smpOptions);
const webpackConfig = {
  plugins: smp.wrapPlugins({
    FooPlugin: new FooPlugin(),
  }),
};

// v1
const smp = new SpeedMeasurePlugin(smpOptions);
const webpackConfig = smp.wrap({
  plugins: [new FooPlugin()],
});

If Using Custom Names

v1 no longer requires you to manually enter each plugin name. If you want to keep any of your custom plugin names, then you can use the new options.pluginNames option:

const fooPlugin = new FooPlugin();
const smp = new SpeedMeasurePlugin({
  pluginNames: {
    customFooPluginName: fooPlugin,
  },
});
const webpackConfig = smp.wrap({
  plugins: [fooPlugin],
});
