Package Exports

cli-ux
cli-ux/lib/index
cli-ux/lib/list
cli-ux/lib/styled/header
cli-ux/lib/styled/json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cli-ux) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

cli-ux

cli IO utilities

Usage

The following assumes you have installed cli-ux to your project with npm install cli-ux or yarn add cli-ux and have it required in your script (TypeScript example):

import cli from 'cli-ux'
cli.prompt('What is your name?')

cli.prompt()

Prompt for user input.

// just prompt for input
await cli.prompt('What is your name?')

// mask input after enter is pressed
await cli.prompt('What is your two-factor token?', {type: 'mask'})

// mask input on keypress (before enter is pressed)
await cli.prompt('What is your password?', {type: 'hide'})

// yes/no confirmation
await cli.confirm('Continue?')

// "press any key to continue"
await cli.anykey()

prompt demo

cli.url(text, uri)

Create a hyperlink (if supported in the terminal)

await cli.url('sometext', 'https://google.com')
// shows sometext as a hyperlink in supported terminals
// shows https://google.com in unsupported terminals

url demo

cli.open

Open a url in the browser

await cli.open('https://oclif.io')

cli.action

Shows a spinner

// start the spinner
cli.action.start('starting a process')
// show on stdout instead of stderr
cli.action.start('starting a process', {stdout: true})

// stop the spinner
cli.action.stop() // shows 'starting a process... done'
cli.action.stop('custom message') // shows 'starting a process... custom message'

This degrades gracefully when not connected to a TTY. It queues up any writes to stdout/stderr so they are displayed above the spinner.

cli.annotation

Shows an iterm annotation

// start the spinner
cli.annotation('sometest', 'annotated with this text')

annotation demo

cli.wait

Waits for 1 second or given milliseconds

await cli.wait()
await cli.wait(3000)

cli.tree

Generate a tree and display it

let tree = cli.tree()
tree.insert('foo')
tree.insert('bar')

let subtree = cli.tree()
subtree.insert('qux')
tree.nodes.bar.insert('baz', subtree)

tree.display()

Outputs:

├─ foo
└─ bar
   └─ baz
      └─ qux
