Webstorm node debugger8/25/2023 ![]() You see the code before transpilation, as you authored it. Original source - You see each module separated from each other, annotated with module names. Generated code - You see each module separated from each other, annotated with module names. You don't see modules separated from each other. Qualitiesīundled code - You see all generated code as a big blob of code. See output.sourceMapFilename to customize the filenames of generated Source Maps. ![]() For development you typically want fast Source Maps at the cost of bundle size, but for production you want separate Source Maps that are accurate and support minimizing. Some of these values are suited for development and some for production. We expect a certain pattern when validate devtool name, pay attention and dont mix up the sequence of devtool string. This can be useful when the original files should be referenced (further config options needed). Source code is not included in SourceMap. When SourceMap is not deployed, but should still be generated, e. Inline the SourceMap to the original file instead of creating a separate file. Note that there is a windows defender issue, which causes huge slowdown due to virus scanning. Recommended for development, because of improved rebuild performance. Generate SourceMap per module and attach it via eval. You will see the original code that you wrote, assuming all loaders support SourceMapping. This prevents setting breakpoints in the middle of lines which doesn't work together with minimizer. ![]() ![]() Only source lines will be mapped and column information will be discarded resp. You will see generated code after the preprocessing by loaders but before additional webpack transformations. You will see the generated code, but each module is shown as separate code file in browser devtools. This is the raw output file without any devtooling support You will see all generated code of a chunk in a single blob of code. The scale is different compared to the build performance, as one would expect rebuilds to be faster than builds.ĭoes it make sense to use this devtool for production builds? It's usually no when the devtool has a negative effect on user experience. How is the performance of the incremental build affected by the devtool setting? Slow devtools might reduce development feedback loop in watch mode. How is the performance of the initial build affected by the devtool setting? Possible choice when using SourceMap only for error reporting purposes. Possible choice when publishing a single file Recommended choice for production builds with high quality SourceMaps. Recommended choice for development builds with high quality SourceMaps. Recommended choice for development builds with maximum performance. Recommended choice for production builds with maximum performance. The devtool option adds the plugin internally so you would end up with the plugin applied twice. Never use both the devtool option and plugin together. Instead of using the devtool option you can also use SourceMapDevToolPlugin/ EvalSourceMapDevToolPlugin directly as it has more options. Those examples will likely help you to understand the differences. The webpack repository contains an example showing the effect of all devtool variants. These values can affect build and rebuild speed dramatically. devtoolĬhoose a style of source mapping to enhance the debugging process. See the source-map-loader to deal with existing source maps. Use the SourceMapDevToolPlugin for a more fine grained configuration. This option controls if and how source maps are generated.
