Source maps lose line number context when used libraries

[lukekarrys]

Because libraries are concatenated and prepended to the js source, they make the line numbers of the bundle no longer mapped to the source maps.

Thanks to @whobubble for bringing up this issue.

To workarround this, I've change the order of the prepend. Now its: the application + external libraries. If you want, I can make a pull request of this.

There is a workaround using the browserify-shim transform. A bit verbose but working example:

package.json

  ...
  "dependencies": {
    "browserify-shim": "~3.3.1"
  },
  "browser": {
    "charFunk": "./clientapp/libraries/charFunk-1.1.1.min.js"
  },
  "browserify-shim": {
    "charFunk": "charFunk"
  }
}

add the transform into the browserify config for moonboots and activate source maps:

    ...
    browserify: {
        debug: true,
        transforms:["browserify-shim"]
    },
    ...

Looks like a documentation update is what's needed, to point people to browserify-shim if they want to maintain line numbers, and a warning that libraries will shift line numbers.

Readme updated.
