productionBrowserSourceMaps
Source Maps are enabled by default during development. During production builds, they are disabled to prevent you leaking your source on the client, unless you specifically opt-in with the configuration flag.
Next.js provides a configuration flag you can use to enable browser source map generation during the production build:
next.config.js
module.exports = {
productionBrowserSourceMaps: true,
}
When the productionBrowserSourceMaps
option is enabled, the source maps will be output in the same directory as the JavaScript files. Next.js will automatically serve these files when requested.
- Adding source maps can increase
next build
time - Increases memory usage during
next build
