Configuration

npmts can be configured to your needs.

npmextra.json

the npmts section in npmextra.json can be used to configure npmts.

Default

Note: When you are using "mode":"default" it'll cause npmts to override any other settings you may have made except for tsOptions (ES target etc.) with default behaviour.

{
  "npmts":{
    "mode":"default"
  }
}

Custom settings

{
  "mode":"custom",
  "test":true,
  "npmts":{
    "ts":{
      "./customdir/*.ts":"./"
    },
    "tsOptions":{
      "declaration":false,
      "target":"ES6"
    },
    "cli":true
  }
}

key	default value	description
"mode"	"default"	"default" will do default stuff and override , "custom" only does what you specify, "merge" will merge default options with whatever you specify on your own
"test"	true	test your module
"ts"	{"./ts/*.ts":"./","./test/test.ts":"./test/"}	allows you to define multiple ts portions
"tsOptions"	{"target":"ES5", "declaration":"true"}	specify options for tsc
"cli"	"false"	some modules are designed to be used from cli. If set to true NPMTS will create a cli.js that wires you dist files up for cli use.
"testConfig"	{ parallel: true, coverage: true }	allows you to control test behaviour. "parallel" controls wether testfiles are run sequentially or in parallel, and "coverage wether to create coverage reports

TypeScript

by default npmts looks for ./ts/*.ts and ./test/test.ts that will compile to ./dist/*.js and ./test/test.js

Use commonjs module system for wiring up files.

Declaration files

npmts also creates declaration files like ./dist/index.d.ts by default. You can reference it in your package.json like this.

"main": "dist/index.js",
"typings": ".dist/index.d.ts",

This is in line with the latest TypeScript best practices. You can then import plugins via the TypeScript import Syntax and tsc will pick up the declaration file automatically.

Some notes:

Typings for third party modules that do not bundle declaration files

NPMTS no longer supports typings.json. Instead use the new TypeScript 2.x approach to typings using the @types/ npm scope.

Instrumentalize Code

npmts instrumentalizes (using istanbul) the created JavaScript code to create a coverage report.

Tests

Any errors will be shown with reference to their originating source in TypeScript thanks to autogenerated source maps.
