Concatenate files while generating or propagating sourcemaps.

Package Exports

  • fast-sourcemap-concat
  • fast-sourcemap-concat/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fast-sourcemap-concat) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Fast Source Map Concatenation

Build Status Build status

This library lets you concatenate files (with or without their own pre-generated sourcemaps), and get a single output file along with a sourcemap.

It was written for use in ember-cli via broccoli-sourcemap-concat.

source-map dependency

We depend on mozilla's source-map library, but only to use their base64-vlq implementation, which is in turn based on the version in the Closure Compiler.

We can concatenate much faster than source-map because we are specifically optimized for line-by-line concatenation.
