+# karma-sourcemap-loader
+
+> Preprocessor that locates and loads existing source maps.
+
+## Why
+
+When you use karma not in isolation but as part of a build process (e.g. using grunt
+or gulp) it is often the case that the compilation/transpilation is done on a previous
+step of the process and not handled by karma preprocessors. In these cases source maps
+don't get loaded by karma and you lose the advantages of having them.
+
+## How it works
+
+This plug-in supports both inline and external source maps.
+
+Inline source maps are located by searching "sourceMappingURL=" inside the javascript
+file, both plain text and base64-encoded maps are supported.
+
+External source maps are located by appending ".map" to the javascript file name.
+So if for example you have Hello.js, the preprocessor will try to load source map from
+Hello.js.map.
+
+## Installation
+
+Just write `karma-sourcemap-loader` as a devDependency in your `package.json`.
+```json
+{
+ "devDependencies": {
+ "karma-sourcemap-loader": "~0.2"
+ }
+}
+```
+
+Or just issue the following command:
+```bash
+npm install karma-sourcemap-loader --save-dev
+```
+
+## Configuration
+
+The code below shows a sample configuration of the preprocessor.
+```js
+// karma.conf.js
+module.exports = function(config) {
+ config.set({
+ preprocessors: {
+ '**/*.js': ['sourcemap']
+ }
+ });
+};
+```
+
+## Credits
+
+Thanks to @goldibex for adding inline source maps support.
