Release Notes

symfony/webpack-encore (@​symfony/webpack-encore)

v7.2.0

Compare Source

• Migrate internal code to TypeScript, ship package with type definitions (better DX and IDE support!)
• Improve the typing of the configuration methods (enableSassLoader(), configureDevServerOptions(), enableVueLoader(), configureBabelPresetEnv(), etc.): options now resolve to the real loader/plugin types, giving full autocompletion and validation in your webpack.config
• Add support for webpack-dev-server ^6.0.0 (requires webpack ^5.102.0 and webpack-cli ^7.0.2)

v7.1.0

Compare Source

• Add support for sass-loader ^17.0.0
• Add support for @vue/babel-plugin-jsx to ^3.0.0, remove support for @vue/babel-plugin-jsx to ^1.0.0
• Update the minimum version of webpack-manifest-plugin to ^6.0.1
• Declare the JS/CSS minifiers as optional peer dependencies without a version constraint, matching minimizer-webpack-plugin behavior
