CHANGELOG

5.0.1

#1349 Fix issue between Encore.enableIntegrityHashes() and filenames with a query-string (@Kocal)

5.0.0

This is a new major version that contains several backwards-compatibility breaks.

Features

#1344 Add options configuration callback to Encore.enableReactPreset() (@Kocal)
#1345 Add support for integrity hashes when asset names contain a query string (@Kocal)

BC Breaks

#1321 Drop support of Node.js 19 and 21 (@Kocal)
#1307 Drop webpack-cli 4 support, only webpack-cli ^5.1.4 is supported (@Kocal)
#1318 Drop webpack-dev-server 4 support, only webpack-dev-server 5 is supported (@Kocal)

The dev-server options have changed between versions 4 and 5, see the official migration guide to v5. For example:

// With webpack-dev-server 4:
Encore.configureDevServerOptions((options) => {
   options.https = {
     ca: "./path/to/server.pem",
     pfx: "./path/to/server.pfx",
     key: "./path/to/server.key",
     cert: "./path/to/server.crt",
     passphrase: "webpack-dev-server",
     requestCert: true,
   };
});

// With webpack-dev-server 5 (now):
Encore.configureDevServerOptions((options) => {
   options.server = {
      type: 'https',
      options: {
         ca: "./path/to/server.pem",
         pfx: "./path/to/server.pfx",
         key: "./path/to/server.key",
         cert: "./path/to/server.crt",
         passphrase: "webpack-dev-server",
         requestCert: true,
      }
   };
});

#1336 Make webpack-dev-server dependency optional (@Kocal)

The webpack-dev-server package is now an optional peer dependency. It has been removed because some projects may not use it, and it was installing a bunch of unnecessary dependencies.

Removing the webpack-dev-server dependency from Encore reduces the number of dependencies from 626 to 295 (-331!), it helps to reduce the size of the node_modules directory and the number of possible vulnerabilities.

To use the webpack-dev-server again, you need to install it manually:

npm install webpack-dev-server --save-dev
# or 
yarn add webpack-dev-server --dev
# or 
pnpm install webpack-dev-server --save-dev

#1308 Drop Vue 2 support (End-Of-Life), only Vue 3 is supported (@Kocal)
#1309 Drop ESLint integration (@Kocal)
#1313 Drop clean-webpack-plugin in favor of webpack's output.clean configuration. The configuration settings supported by Encore.cleanupOutputBeforeBuild have changed (@stof)
#1324 Drop css-minimizer-webpack-plugin 5 support, only css-minimizer-webpack-plugin 7 is supported (@Kocal)
#1342 Replace assets-webpack-plugin dependency by an internal plugin, to generate entrypoints.json file (@Kocal)
#1317 Drop support of sass-loader ^13 and ^14, add support for sass-loader ^16 (@Kocal)

The sass-loader's options have changed, the modern options are now used by default. Though not recommended, you must specify the option api: 'legacy' if you want to keep the legacy options. For example:

// With the legacy API:
Encore.enableSassLoader((options) => {
    options.api = 'legacy';
    options.includePaths = [/*...*/];
});

// With the modern API (default):
Encore.enableSassLoader((options) => {
   options.loadPaths = [/*...*/];
});

#1319 Drop support of css-loader ^6, add support for css-loader ^7.1 (@Kocal)

Since css-loader 7.0.0, styles imports became named by default. It means you should update your code from:

import style from "./style.css";

console.log(style.myClass);

to:

import * as style from "./style.css";

console.log(style.myClass);

There is also a possibility to keep the previous behavior by configuring the css-loader's modules option:

config.configureCssLoader(options => {
   if (options.modules) {
       options.modules.namedExport = false;
       options.modules.exportLocalsConvention = 'as-is';
   } 
});

Important

If you use CSS Modules inside .vue files, until vuejs/vue-loader#1909 is merged and released, you will need to restore the previous behavior by configuring Encore with the code above.

#1333 Replace chalk by picocolors (@Kocal)

4.7.0

Features

#1284 Improve ESLint and Babel help messages, when enabling ESLint integration (@Kocal)
#1285 Add support for PNPM for installation commands (@Kocal)
#1286 Add support for Node.js 22 (@Kocal)
#1299 Add support for less-loader 12 (@Kocal)
#1301 Add support for postcss-loader 8 (@Kocal)
#1302 Add support for stylus-loader 8 (@Kocal)
#1295 Add JSX support for Vue 3 (@Kocal)

Enabling JSX support for Vue 3 is done with the Encore.enableVueLoader():

Encore.enableVueLoader(() => {}, { 
    useJsx: true,
    version: 3,
});

If you don't have a custom Babel configuration, then you're all set! But if you do, you may need to adjust it to add @vue/babel-plugin-jsx plugin to your Babel configuration:

// babel.config.js
module.exports = {
    plugins: [
        '@vue/babel-plugin-jsx'
    ]
};

v4.1.0

October 17th, 2022

Features

Add support for Svelte - #781 thanks to @zairigimad

Bug Fixes

Support for Vue 2 was accidentally dropped in 4.0.0, and was re-added - #1157 thanks to @Kocal.

v4.0.0

This major release makes Encore compatible with Yarn Plug'n'Play and pnpm.

BC Breaks

The following dependencies must be added in your package.json: webpack webpack-cli @babel/core @babel/preset-env (#1142 and #1150):

npm install webpack webpack-cli @babel/core @babel/preset-env --save-dev

# or via yarn
yarn add webpack webpack-cli @babel/core @babel/preset-env --dev

The following dependencies must be removed from your package.json and Babel configuration: @babel/plugin-syntax-dynamic-import @babel/plugin-proposal-class-properties, since they are already included in @babel/preset-env (#1150):

npm remove @babel/plugin-syntax-dynamic-import @babel/plugin-proposal-class-properties

# or via yarn
yarn remove @babel/plugin-syntax-dynamic-import @babel/plugin-proposal-class-properties

and remove it from your Encore configuration:

Encore.configureBabel((options) => {
-    config.plugins.push('@babel/plugin-proposal-class-properties');
+    
})

v3.1.0

August 24th, 2022

Add vue 2.7 feature to allow dropping vue-template-compiler - #1134 thanks to @billyct

v3.0.0

July 8th, 2022

This major release drops support for Node 12 (minimum is now Node 14) and also bumps some dependencies up a new major version.

BC Breaks

In #1122 support for Node 12 was dropped.
In #1133, the following dependencies were bumped a major version:
- css-minimizer-webpack-plugin 3.4 -> 4.0 (4.0 just drops Node 12 support)
- less-loader 10 -> 11
- postcss-loader 6 -> 7
- sass-loader 12 -> 13
- stylus 0.57 -> 0.58
- stylus-loader 6 -> 7

If you're using any of these (all are optional except for css-minimizer-webpack-plugin and are extended them with custom configuration, check the CHANGELOG of each for any possible BC breaks).

Feature

#1133 - Increasing dependencies - @weaverryan
#1125 - Changing to support the "server" options object for webpack-dev-server - @weaverryan
#1122 - Allow sass-loader:^13.0.0, require node >= 14 - @jmsche
#1118 - Use cli param server-type to define devServer https mode - @thegillou

v2.1.0

May 5th, 2022

Feature

#1093 - Allow sass-embedded - @IonBazan

v2.0.0

May 3rd, 2022

This is a new major version that contains several backwards-compatibility breaks.

BC Breaks

The following dependencies were upgraded a major version. It's unlikely these will cause problems, unless you were further configuring this part of Encore:

clean-webpack-plugin Version 3 to 4: dropped old Node & Webpack version support
css-loader Version 5 to 6: dropped old Node version support & CHANGELOG
css-minimizer-webpack-plugin Version 2 to 3: dropped old Node version support
loader-utils REMOVED
mini-css-extract-plugin Version 1.5 to 2.2.1: dropped old Node & Webpack version support & CHANGELOG
pretty-error Version 3.0 to 4.0: dropped old Node version support
resolve-url-loader Version 3.0 to 5.0: dropped old Node version support, requires postcss ^8.0, remove rework engine & CHANGELOG
style-loader Version 2 to 3: dropped old Node and Webpack version support & CHANGELOG
yargs-parser Version 20.2 to 21: dropped old Node version support

Additionally, Encore changed the supported versions of the following packages, which you may have installed to enable extra features:

eslint Minimum version increased from 7 to 8
eslint-webpack-plugin Minimum version increased from 2.5 to 3
fork-ts-checker-webpack-plugin Minimum version increased from 5 to 6 CHANGELOG
less-loader Minimum version increased from 7 to 10
postcss-loader Minimum version increased from 4 to 6
preact Minimum version increased from 8 to 10 CHANGELOG
sass-loader Minimum version increased from 9 to 12
stylus Minimum version increased from 0.54 to 0.56
stylus-loader Minimum version increased from 3 to 6 CHANGELOG
vue-loader Minimum version increased from 16 to 17 CHANGELOG
Removed Encore.enableEslintLoader(): use Encore.enableEslintPlugin().
If using enableEslintPlugin() with the @babel/eslint-parser parser, you may now need to create an external Babel configuration file. To see an example, temporarily delete your .eslintrc.js file and run Encore. The error will show you a Babel configuration file you can use.
With configureDefinePlugin(), the options['process.env'] key format passed to the callback has changed (see #960). If you are using configureDefinePlugin() to add more items to process.env, your code will need to change:

Encore.configureDefinePlugin((options) => {
-    options['process.env']['SOME_VAR'] = JSON.stringify('the value');
+    options['process.env.SOME_VAR'] = JSON.stringify('the value');
})

Bug Fix

#697 - Fix source maps being generated by default in dev - @Lyrkan

0.28.0

Don't make @babel/preset-env use forceAllTransforms option in production - this will reduce build size in production for environments that only need to support more modern browsers - #612 thanks to @Lyrkan.
Added support with enablePostCssLoader() to process files ending in .postcss or using lang="postcss" in Vue - #594 thanks to @Lyrkan.
Allow resolve-url-loader to be configured via enableSassLoader() - #603 thanks to @diegocardoso93.
Support was removed from Node 9 (a no-longer-supported version of Node) - #585 thanks to @weaverryan
[BC Break] Removed the ability to use [chunkhash] in configureFilenames(), which was already deprecated and no longer reliable - #608 thanks to @Lyrkan.

0.27.0

[Behavior Change] The Babel configuration sourceType default was changed from not being specified (so, the default module was used) to unambiguous. This is to help Babel's useBuiltIns functionality properly determine if a require or import should be automatically added to your files, based on that file's style - #555 thanks to @Lyrkan.
Added JSX support to Vue! #553 thanks to @Kocal.
Cleaned up the jsdoc in index.js to add better docs and better IDE auto-completion - #550 thank sto @Lyrkan.

0.26.0

[Behavior change] The Babel useBuiltIns option default value changed from entry to false, which means that polyfills may no longer be provided in the same way. This is due to a change in Babel and core-js. To get the same functionality back, run yarn add core-js --dev, then use:
```
Encore.configureBabel(() => {}, {
    useBuiltIns: 'entry', // or try "usage"
    corejs: 3
})
```
This comes from #545 thanks to @Lyrkan.
Added the ability to "resolve" CSS and Sass files without specifying the file extension and by taking advantage of the sass or style attribute in an npm package. For example, you can now import the main Bootstrap SASS file from within a SASS file by saying @import ~bootstrap. This will use the sass attribute from the bootstrap package.json file to find which file to load. #474 thanks to @deAtog.
Added a new Encore.enableIntegrityHashes(), which will cause a new integrity key to be added to entrypoints.json with integrity values that can be included in the script or link tag for that asset - #522 thanks to @Lyrkan.
Allow some parts of configureBabel() to be used, even if there is an external .babelrc configuration file - #544 thanks to @Lyrkan.

0.25.0

[BC BREAK] Various dependency versions were updated, including css-loader updated from ^1.0.0 to ^2.1.1 and resolve-url-loader updated from ^2.3.0 to ^3.0.1. The minimum Node version was also bumped from 6 to 8. See #540 for more details.
Added Encore.disableCssExtraction() if you prefer your CSS to be output via the style-loader - #539 thank to @Lyrkan.
Added Encore.configureLoaderRule() as a way to configure the loader config that Encore normally handles - #509 thanks to @Kocal.
Babel cache is no longer used for production builds to avoid a bug where the cache prevents browserslist from being used - #516 thanks to @Lyrkan.

0.24.0

Add CSS modules support in Vue.js for Sass/Less/Stylus - #511 thanks to @Lyrkan
Allow to use Dart Sass instead of Node Sass - #517 thanks to @Lyrkan
Allow to set a custom context in copyFiles - #518 thanks to @Lyrkan
Improve 'Install x to use y' and 'Unrecognized method' error messages - #520 thanks to @Lyrkan
Allow to set @babel/preset-env's useBuiltIns option - #521 thanks to @Lyrkan
Allow setOutputPath to create nested directories - #525 thanks to @Lyrkan

0.23.0

Add support for CSS modules in Vue - #508 thanks to @Lyrkan
Store externals in an array - #495 thanks to @deAtog
Add Encore.isRuntimeEnvironmentConfigured() - #500 thanks to @stof.
Add the ability to configure watch options - #486 thanks to @Kocal
Enabled cache and parallelism for terser for faster builds - #497 thanks to @Kocal

0.22.0

[BC BREAK] The values/paths in entrypoints.json were previously stripped of their opening slash. That behavior has been changed: the opening slash is now included: Before: build/foo.js, After: /build/foo.js.

0.21.0

[BC BREAK] Webpack was upgraded to version 4. This includes a number of major and minor changes. The changes are listed below under the Webpack 4 Upgrade section.
[BC BREAK] The createSharedEntry() no longer can be passed an array of files. Instead, set this to just one file, and require the other files from inside that file.
[DEPRECATION] You must now call either Encore.enableSingleRuntimeChunk() or Encore.disableSingleRuntimeChunk(): not calling either method is deprecated. The recommended setting is Encore.enableSingleRuntimeChunk(). This will cause a new runtime.js file to be created, which must be included on your page with a script tag (before any other script tags for Encore JavaScript files). See the documentation above enableSingleRuntimeChunk() in index.js for more details.
[BEHAVIOR CHANGE] Previously, without any config, Babel was configured to "transpile" (i.e. re-write) your JavaScript so that it was compatible with all browsers that currently have more than 1% of the market share. The new default behavior is a bit more aggressive, and may rewrite even more code to be compatible with even older browsers. The recommendation is to add a new browserslist key to your package.json file that specifies exactly what browsers you need to support. For example, to get the old configuration, add the following to package.json:

{
    "browserslist": "> 1%"
}

See the browserslist library for a full description of all of the valid browser descriptions.

Added a new copyFiles() method that is able to copy static files into your build directory and allows them to be versioned. #409 thanks to @Lyrkan
Introduced a new configureSplitChunks() method that can be used to further configure the optimizations.splitChunks configuration.
A new entrypoints.json file is now always output. For expert use-cases, the optimizations.splitChunks.chunks configuration can be set via configureSplitChunks() to all. Then, you can write some custom server-side code to parse the entrypoints.js so that you know which script and link tags are needed for each entry.
The "dynamic import" syntax is now supported out of the box because the @babel/plugin-syntax-dynamic-import babel plugin is always enabled. This allows you to do "Dynamic Imports" as described here: https://webpack.js.org/guides/code-splitting/#dynamic-imports
A new "version check" system was added for optional dependencies. Now, when you install optional plugins to support a feature, if you are using an unsupported version, you will see a warning. "Package recommendation" errors (i.e. when you enable a feature but you are missing some packages) will also contain the version in the install string when necessary (e.g. yarn add foo@^2.0).
Support was added handlebars-loader by calling enableHandlebarsLoader(). #301 thanks to @ogiammetta
Support was added for eslint-loader by calling enableEslintLoader(). #243 thanks to @pinoniq
The css-loader can now be configured by calling configureCssLoader(). #335 thanks to @XWB
It's now possible to control the exclude for Babel so that you can process certain node_modules packages through Babel - use the new second argument to configureBabel() - #401 thanks to @Lyrkan.

Webpack 4 Upgrade Details

Node 7 is no longer supported. This is because the new mini-css-extract-plugin does not support it (and neither) does Yarn.
For Preact, the necessary plugin the user needs to install changed from babel-plugin-transform-react-jsx to @babel/plugin-transform-react-jsx.
The NamedModulesPlugin was removed.
The babel-preset-env package (which was at version ^1.2.2) was removed in favor of @babel/preset-env.
ExtractTextPlugin was removed and replaced with mini-css-extract-plugin. Accordingly, extractTextPluginOptionsCallback() was removed.
Support for CoffeeScript was entirely removed.
Actual lang="sass" no longer works for Vue. However, lang="scss" continues to work fine.
uglifyjs-webpack-plugin was replaced by terser-webpack-plugin. If you're using configureUglifyJsPlugin(), please switch to configureTerserPlugin() instead.
