Zero Config (#0CJS)

Entry / Output

No need for explicit specify entry and output properties in the webpack configuration.

In Webpack 4 those fields are defaulted to:

{
    "entry": "./src",
    "output": "./dist"
}

Mode

Webpack mode reduce the required configuration for an useful build:

  • development: this mode provide useful error messages and is optimized for speed (unminified bundle)
  • production: enables optimizations out of the box (scope hoisting, tree shaking, minification, etc.)
webpack --mode production

There is also another hidden none mode which disables everything (available only inside the configuration object).

Changes

  • Dropped Node.js 4 support. Therefore, more benefits from ES6 features (optimizations from V8).
  • Sets of defaults with production and development modes.
  • Changes on plugins (Some actives depending on mode. CommonsChunkPlugin was removed)
  • Optimizations, performance boost and many more...
  • Read changeset of Webpack v4.0.0
