Webpack TypeScript Formatter (tsfmt-loader)

A Webpack Preloader that uses the typescript-formatter library typescript-formatter.

Installation

npm install tsfmt-loader --save-dev

Usage

Preloader configuration

module: {
  preLoaders:[
    {
      test: /\.ts$/,
      loader: 'tsfmt-loader',
      query: {
        replace: true
      }
    }
  ]
}

Options

All options have a default and can be overwritten in the query object of your preloader configuration.

[baseDir]              The base directory for your configuration files
[verbose=false]       makes output more verbose
[replace=true]        replace .ts file
[tsconfig=true]       Reads your tsconfig.json for formatting rules
[tslint=true]         Reads your tslint.js for formatting rules
[editorconfig=true]   Reads your .editorconfig for formatting rules
[tsfmt=true]          Reads your tsfmt.json for formatting rules

Note

If you are using other preloaders it is suggested you list this one last. Webpack executes preloaders in reverse order and this will allow the formatter to execute before other tasks like linters.
