Sourcemaps off by one line in Chrome, with Ruby on Rails, Webpack, and React JS
There was a bug in chrome, try the latest version, also on your webpack config try using different sourcemaps on devtool try all of these to see if one works for inline source map:
inline-source-map
cheap-inline-source-map
for other different configs:
cheap-source-map
cheap-module-source-map
cheap-module-eval-source-map
on webpack config:
{...devtool:'source-map'...}
