babel-plugin-node-sourcemap-support

babel-plugin-node-sourcemap-support

Adds support for sourcemaps to a node app in a hacky fashion.

The plugin shamefully depends on adding a module to your project directory. A require statement is inserted into your entry files to require the source-map-support module.

It can be argued that it is a better idea to install source-map-support into your project and require it yourself.

install

npm install babel-plugin-node-sourcemap-support

example

.babelrc

{
  "plugins": [
    ["node-sourcemap-support", {
      "src": "./path/to/src",
      "dest": "./path/to/out/dir",
      "entries": [
        "app.js",
        "foo/bar.js"
      ]
    }]
  ]
}

babel --source-maps inline ./path/to/src --out-dir ./path/to/out/dir

options

src: string, ./src

path to source files directory

dest: string, ./build

path to transpiled files directory

entries: [], ['index.js']

array of app entry file paths, relative to src

supportModulePath: string, _build-modules/source-map-support-register.js

path where the module will be added, relative to dest

cache: boolean, true

You probably should not turn this off. It prevents the support module from being redundantly copied to dest every time babel transpiles a file.
