Documentation

You'll need to install grunt-txtypescript first:

npm install grunt-txtypescript --save-dev

or add the following line to devDependencies in your package.json

"grunt-txtypescript": "",

Then modify your Gruntfile.js file by adding the following line:

grunt.loadNpmTasks('grunt-txtypescript');

Then add some configuration for the plugin like so:

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      dest: 'where/you/want/your/js/files',
      options: {
        module: 'amd', //or commonjs
        target: 'es5', //or es3
        basePath: 'path/to/typescript/files',
        sourceMap: true,
        declaration: true
      }
    }
  },
  ...
});

If you want to create a js file that is a concatenation of all the ts file (like -out option from tsc), you should specify the name of the file with the '.js' extension to dest option.

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      dest: 'where/you/want/your/js/file.js',
      options: {
        module: 'amd', //or commonjs
      }
    }
  },
  ...
});

Options

typescript options

original options

####generateTsConfig type: string | boolean

generateTsConfig option will generate the content and equivalent tsconfig.json that are specified in the option. The value specify the directory name to be output. It is output to the current directory when you specify true.

references

type: string | string[]

Set auto reference libraries.

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      options: {
        references: [
          "core",       //lib.core.d.ts
          "dom",        //lib.dom.d.ts
          "scriptHost", //lib.scriptHost.d.ts
          "webworker",  //lib.webworker.d.ts
          "path/to/reference/files/**/*.d.ts"
        ]
      }
    }
  },
  ...
});

watch

type: string | boolean | { path?:<string | string[]``>; before?: <string|string[]>; after?: <`string` | `string[]>; atBegin: boolean }

Watch .ts files. It runs very quickly the second time since the compilation. It is because you only want to read and output file is limited.

Specify the directory where you want to monitor in the options.

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      options: {
        watch: 'path/to/typescript/files' //or ['path/to/typescript/files1', 'path/to/typescript/files2']
      }
    }
  },
  ...
});

If you specify the true, then automatically detects the directory.

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      options: {
        watch: true //Detect all target files root. eg: 'path/to/typescript/files/'
      }
    }
  },
  ...
});

For expansion of the future, You can also be specified 'object'.

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      options: {
        watch: {
          path: 'path/to/typescript/files', //or ['path/to/typescript/files1', 'path/to/typescript/files2']
          before: ['beforetasks'],   //Set before tasks. eg: clean task
          after: ['aftertasks']      //Set after tasks.  eg: minify task
          atBegin: true              //Run tasks when watcher starts. default false
        }
      }
    }
  },
  ...
});

basePath(obsolete)

type: string

Path component to cut off when mapping the source files to dest files.

keepDirectoryHierarchy(obsolete)

type: boolean

Path component to cut off when mapping the source files to dest files.

grunt.initConfig({
  ...
  typescript: {
    base: {
      src: ['path/to/typescript/files/**/*.ts'],
      dest: 'bin'
      options: {
        keepDirectoryHierarchy: true
      }
    }
  },
  ...
});

If keepDirectoryHierarchy option is true, it is output as follows.

/bin
- /path
--- /to
----- /typescript
------- /files
--------- *.ts 

If keepDirectoryHierarchy option is false or not set, it is output as follows. It is same way as the tsc.

/bin
- *.ts
