This section describes the lifetime hooks provided by Rsbuild plugin.
Common Hooks
modifyRsbuildConfig
: Modify raw config of Rsbuild.modifyBundlerChain
: Modify config of Rspack or webpack via the bundler chain api.modifyWebpackChain
: Modify webpack-chain.modifyWebpackConfig
: Modify raw config of webpack.modifyRspackConfig
: Modify raw config of Rspack.onBeforeCreateCompiler
: Called before creating compiler instance.onAfterCreateCompiler
: Called after the compiler object is created, but before the build is executed.Build Hooks: Called only when the build method is executed to build the production outputs.
onBeforeBuild
: Called before the production build is executed.onAfterBuild
: Called after executing the production build, you can get the build stats.Dev Server Hooks: Called only when the startDevServer method is executed to run the development server.
onBeforeStartDevServer
: Called before starting the development server.onAfterStartDevServer
: Called after starting the development server.onDevCompileDone
: Called after each development compile.Other Hooks
onExit
: Called when the process is going to exit.Modify the config passed to the Rsbuild, you can directly modify the config object, or return a new object to replace the previous object.
Bundler chain is a subset of webpack chain, which contains part of the webpack chain API that you can use to modify both webpack and Rspack configuration.
modifyBundlerChain
is used to call the bundler chain to modify the Rspack configuration.
This hook only supports modifying the configuration of the non-differentiated parts of webpack and Rspack. For example, modifying the devtool configuration option (webpack and Rspack have the same devtool property value type), or adding an Rspack-compatible webpack plugin.
To modify the final Rspack config object, you can directly modify the config object, or return a new object to replace the previous object.
onBeforeCreateCompiler
is a callback function that is triggered after the Compiler instance has been created, but before the build process begins. This hook is called when you run rsbuild.startDevServer
, rsbuild.build
, or rsbuild.createCompiler
.
You can access the Compiler instance object through the compiler
parameter:
If the current bundler is webpack, you will get the webpack Compiler object.
If the current bundler is Rspack, you will get the Rspack Compiler object.
Type
onAfterCreateCompiler
is a callback function that is triggered after the compiler instance has been created, but before the build process. This hook is called when you run rsbuild.startDevServer
, rsbuild.build
, or rsbuild.createCompiler
.
You can access the Compiler instance object through the compiler
parameter:
If the current bundler is webpack, you will get the webpack Compiler object.
If the current bundler is Rspack, you will get the Rspack Compiler object.
Type
onBeforeBuild
is a callback function that is triggered before the production build is executed. You can access the final configuration array of the underlying bundler through the `bundlerConfigs' parameter:
If the current bundler is webpack, you will get a webpack configuration array.
If the current bundler is Rspack, you will get an Rspack configuration array.
The configuration array can contain one or more configurations, depending on the current target
config of Rsbuild.
Type
onAfterBuild
is a callback function that is triggered after running the production build. You can access the build result information via the `stats' parameter:
If the current bundler is webpack, you will get webpack Stats.
If the current bundler is Rspack, you will get Rspack Stats.
Type
Called before starting the development server.
Called after starting the development server, you can get the port number through the port
parameter.
Called after each development environment build, you can use isFirstCompile
to determine whether it is the first build.
Called when the process is going to exit, this hook can only execute synchronous code.
