NPM version Build Status Coverage Status License Join the chat at https://gitter.im/ipipeto/Lobby

Interactive cli tool that lists and run package.json scripts.

Table of Contents


⬇️ Install

$ npm install -g ntl

🔎 Usage

Navigate to any folder containing a package.json file (usually a Node.js project) that has configured scripts, then just use the ntl command:

ntl

You can also specify a path to a project folder containing a package.json file:

ntl ./my-node-project

😍 Features

  • Interactive interface that lists all package.json scripts
  • Select any item in the interactive interface to execute that task
  • Add descriptions to each task that can be shown in the UI
  • Multiple interactive interfaces (menu list, autocomplete fuzzy search)
  • Many options to customize the UI (exclude scripts, amount of items, etc)
  • Easy to repeat last ran script (nt and rerun options)
  • Run multiple tasks
    • Repeat previously set of ran tasks
    • Preserve order of selection

📚 Customize

Custom runner

By default Node Task List tries to use npm to run the configured script tasks. In case you want to use a custom runner (e.g: yarn or pnpm) you can configure ntl to use whatever runner you prefer.

That can be configured system-wide by setting the environment variable in your profile file (.bashrc or .bash_profile for macos). In case you only want to ever use yarn as your node task runner, you should set:

# .bashrc (linux) OR .bash_profile (macos)
export NTL_RUNNER=yarn

Keep in mind environment variables are flexible enough that they can also be set temporarily prior to running a command, so the following would also work:

NTL_RUNNER=yarn ntl

You can also define a runner in a per-project basis using the ntl configuration of your package.json, e.g:

{
  "name": "<project>",
  "version": "1.0.0",
  "ntl": {
    "runner": "yarn"
  }
}

Using task descriptions

📝 You can define descriptions for your tasks in your package.json file by defining a ntl section, e.g:

{
  "name": "<project>",
  "version": "1.0.0",
  "scripts": {
    "build": "make build",
    "coverage": "jest --coverage",
    "test": "jest"
  },
  "ntl": {
    "descriptions": {
      "build": "Builds the project",
      "coverage": "Run test outputing code coverage",
      "test": "Run project's tests"
    }
  }
}

These descriptions will be shown anytime you run ntl.


Displaying task contents

Use the --info or simply -i option in order to display the contents of each script task, like:

$ ntl -i
⬢  Node Task List
? Select a task to run: (Use arrow keys)
❯ generate-manual › maked-man README.md > man/man1/ntl.1
          pretest › eslint cli.js rerun.js test
             test › cross-env NTL_NO_RERUN_CACHE=1 tap

Task contents will also be shown when using the --descriptions option and no description is available for a given item.


Exclude tasks from UI

You can define a list of scripts to be excluded from the interactive menu using the --exclude option:

$ ntl -e coverall tasks
⬢  Node Task List
? Select a task to run: (Use arrow keys)
❯ test
  test:watch

You can also use a wildcard character to exclude multiple scripts:

$ ntl -e "test*"
⬢  Node Task List
? Select a task to run: (Use arrow keys)
❯ coveralls
  tasks

Exclude tasks with missing descriptions

You can also filter out items that doesn't have a description using the --descriptions-only or -o option.


Customize cache

ntl uses a cache system that stores the last ran command for each project in order to make it easier for users to repeat it. Given its importance, the following environment variables are available in order to customize its location and size:

  • NTL_RERUN_CACHE_DIR: Defines a directory to store the cache file
  • NTL_RERUN_CACHE_NAME: Filename to use for the cache
  • NTL_RERUN_CACHE_MAX: Number of items to store in the cache (defaults to 10)
  • NTL_NO_RERUN_CACHE: When defined, avoid the cache system completely

For example, if a given user wanted to store its cache in ~/.ntl/cache location and save up to 100 items in it, they could add the following to their .bashrc (linux) or .bash_profile (macos):

export NTL_RERUN_CACHE_DIR=$HOME
export NTL_RERUN_CACHE_NAME=cache
export NTL_RERUN_CACHE_MAX=100

The cache can also be customized through command line options:

  • --rerun-cache-dir Defines a directory to store the cache file
  • --rerun-cache-name: Filename to use for the cache
  • --no-rerun-cache: Avoids the cache system completely

UI Size

You can increase/reduce the size of the presented UI list using the --size or -s option. In this example we just increased the size of the list to show up to 12 items at once:

$ ntl -s 12
⬢  Node Task List
? Select a task to run:
❯ build
  generate-manual
  hello
  bomdia
  bonjour
  test
  test:dev
  test:ci
  test:integration
  test:unit
  test:e2e
  start

The default size value is 7 items.


🔄 Repeat the last ran task

ntl provides many options to make it easier to rerun the last task, either through having it selected as default option the next time you run the ntl command, or by using one of the following:

  • The ultra convenient way: nt command shorthand 😎 (You should think of nt as: "ok, just run the last node task", in contrast to ntl which should be interpreted as: "ok, give me the node task list again") in case no previous task is available, running nt will behave exactly as ntl
  • Using a --rerun or -r flag, e.g: ntl -r
  • Prepending the NTL_RERUN env variable, e.g: NTL_RERUN=true ntl

Ⓜ️ Run multiple tasks

Using the --multiple or -m option, the interface becomes a checkbox-based list that allows you to select multiple tasks and run them in serial.

$ ntl -m
⬢  Node Task List
? Select a task to run:
 ◯ start
 ◉ test
❯◉ test:ci

Better yet, combine that with the rerun feature and you can repeat multiple tasks using the nt command.

Run multiple tasks in order of selection

You can run multiple tasks in the order you pick them 😎 Use the --ordered or -O option:

$ ntl -O
⬢  Node Task List
? Select a task to run: (Press <space> to select, <r> to res
et)
 ◯   bar › Test task
 ◯   foo › Test task
❯2 hello › Hello world
 ◯ start › Start the development server
 1  test › Run all tests for the project

Run in autocomplete or fuzzy search mode

Use --autocomplete or -A option in order to use an interface variation that allows you to type the name of the task instead of browsing through an arrow-based menu. This mode can be very helpful when managing a long list of tasks.

$ ntl -A
⬢  Node Task List
? Select a task to run: t
❯ pretest
  test
  start

Tips

ntl as default task

You can define ntl as a dev dependency and one of the tasks of your project, specially start - so whenever someone runs npm start or yarn start they get the convenient ntl interface. Like in the following package.json example:

{
  "name": "<project>",
  "version": "1.0.0",
  "scripts": {
    "start": "ntl"
  },
  "devDependencies": {
    "ntl": "^5.0.0"
  }
}

Exclude scripts

You can also define a task that invokes ntl while excluding other tasks, e.g:

{
  "scripts": {
    "test": "jest --coverage",
    "test:watch": "jest --coverage --watchAll",
    "coveralls": "jest --coverage --coverageReporters=text-lcov | coveralls",
    "tasks": "ntl --exclude coverall tasks"
  }
}

Included command aliases

  • ntl The default command
  • nodetasklist Longhand version in case users have conflicting ntl commands
  • npm-tasklist Legacy longhand version
  • nt Rerun last script shortcut
  • nodetask Rerun last script longhand
