Most modern bundlers, minifiers and compilers support the generation of source maps:
When generating source maps you normally have the option to include the source content within the source map or leave it in the external source files. If you leave it external Bugsnag will need access to those source files to display the context of the error (without it we will just display the source file and line number in the stacktrace).
If you host the source map Bugsnag can fetch it when an error is received. To achieve this you can include the special
X-SourceMap property in the header.
Most minification tools will automatically add the
When generating source maps you’ll usually have the option to include the source content within the source map or leave it in the external source files. If you have not included the source content in the source map we will also attempt to fetch the source files based on the path specified in the source map.
If your server policy denies access to external IP addresses and websites, you will need to whitelist the IP addresses below. A whitelist provides access to designated IP addresses and sites that would otherwise be prevented by your security policy.
You can upload your source maps to Bugsnag using one of the following options:
Alternatively, you can interact with our upload API directly.
You can review a list of your uploaded maps, and delete any unneeded ones, within your dashboard:
