The **new‑relic-source-map-webpack-plugin** is a small Webpack plugin that automatically uploads generated JavaScript source‑map files to New Relic’s Browser monitoring service during a build. It is aimed at front‑end teams who use Webpack and want to automate sourcemap publishing (typically in production builds) so that error stacks in New Relic can be de‑obfuscated. The plugin is configurable with New Relic credentials, asset URLs, release identifiers, and a “noop” flag for disabling uploads in non‑production builds.
