Builder provides a debug mode to troubleshoot problems, you can add the DEBUG=builder
environment variable when executing a build to enable Builder's debug mode.
In debug mode, Builder will output some additional log information, and write the Builder config and webpack config to the dist directory, which is convenient for developers to view and debug.
In debug mode, you will see some additional information output from the shell, among which are some process logs starting with debug
, indicating what operations are performed inside the Builder.
In addition, the following logs will be output in the Shell, indicating that the Builder has written the internally generated build configs to disk, and you can open these config files to view the corresponding content.
In debug mode, Builder will automatically generate dist/builder.config.js
file, which contains the final generated Builder config. In this file, you can know the final result of the Builder config you passed in after being processed by the framework and Builder.
The structure of the file is as follows:
For a complete introduction to Builder config, please see the Builder Config chapter.
If the current project is built using webpack, then in debug mode, Builder will also automatically generate dist/webpack.config.web.js
file, which contains the final generated webpack config. In this file, you can see what is included in the config that Builder finally passes to webpack.
The structure of the file is as follows:
In addition, if the project configures additional build targets, such as enabling the SSR capability of the framework (corresponding to additional Node.js build target), an additional webpack.config.node.js
file will be generated in the dist
directory, corresponding to the webpack config for SSR bundles.
For a complete introduction to webpack configs, please see webpack official documentation.
If the current project is built using Rspack, then in debug mode, Builder will also automatically generate dist/rspack.config.web.js
file, which contains the final generated Rspack config. In this file, you can see what is included in the config that Builder finally passes to Rspack.
The structure of the file is as follows:
For a complete introduction to Rspack configs, please see Rspack official documentation.
