Fork changes

You can customize the HTTP request made when retrieving remote files. If ~/.source-map-cli.json exists and contains a key matching the origin of the URL then you can add headers to the request.

Example:

{
  "https://example.com": {
    "headers": {
      "Cookie": "session=0123456789abcdef"
    }
  }
}

Other changes:

• Automatically adds .map to the path/URL if missing.
• Line and column information can be passed in the same argument as the URL (common stacktrace format), e.g. https://example.com/js/main.js.map:1:22012

Install fork with:

npm install -g git+https://github.com/spotxyz/source-map-cli.git

Verify you are using the new version:

$ source-map --version
1.0.2

Source-map CLI

Command-line interface to the source-map module.

npm install --global source-map-cli

Usage

The tool accepts source-map commands to operate with source maps.

resolve [options] <uri> <line> <column>

The resolve command accepts a source map (either a path or a URL), a line and column and returns the original source file name, line and column, along with a context (usually the name of the variable or function).

$ source-map resolve bundle.js.map 1 28
Maps to source.js:2:10 (baz)

   return baz(bar);
          ^

Context

Additional lines of context can be shown by including the --context [num] option.

Column marker

It is possible to prevent the column marker to be shown with the --no-marker option.
