fgbg v0.1.5

fgbg

fgbg is a lightweight tool that can run multiple commands concurrently, keeping one of them in the foreground and the rest silenced in the background.

It was built to solve the problem of running tests in watch mode for a TypeScript project. With fgbg you can have the test runner watch for changes in *.js files while you compile your *.ts sources into JavaScript in the background.

Installation

npm install --save-dev fgbg

Example Usage

From the command line:

npx fgbg 'ava --watch' 'tsc --watch'

Or as a script in your package.json:

   "scripts": {
     "test": "ava",
+    "test:watch": "fgbg 'ava --watch' 'tsc --watch'
   },

npm run test:watch

Additional arguments

Forward additional arguments to the foreground command using -- as a separator.

npx fgbg 'ava --watch' 'tsc --watch' -- src/foo.test.ts
