## Installation

```bash

npm install karma-typescript-preprocessor --save-dev

```

## Configuration

The code below shows the sample configuration of the preprocessor.

```js

// karma.conf.js

module.exports = function(config) {

  config.set({

    preprocessors: {

      '**/*.ts': ['typescript']

    },

    typescriptPreprocessor: {

      // options passed to the typescript compiler

      options: {

        sourceMap: false, // (optional) Generates corresponding .map file.

        target: 'ES5', // (optional) Specify ECMAScript target version: 'ES3' (default), or 'ES5'

        module: 'amd', // (optional) Specify module code generation: 'commonjs' or 'amd'

        noImplicitAny: true, // (optional) Warn on expressions and declarations with an implied 'any' type.

        noResolve: true, // (optional) Skip resolution and preprocessing.

        removeComments: true, // (optional) Do not emit comments to output.

        concatenateOutput: false // (optional) Concatenate and emit output to single file. By default true if module option is omited, otherwise false.

      },

      // transforming the filenames

      transformPath: function(path) {

        return path.replace(/\.ts$/, '.js');

      }

    }

  });

};

```

If you set the `sourceMap` option to `true` then the generated source map will be inlined as a data-uri.

All TypeScript compiler options are defined [here](https://github.com/Microsoft/TypeScript/blob/0f67f4b6f1589756906782f1ac02e6931e1cff13/lib/typescript.d.ts#L1445-L1500).
