Open stuff like URLs, files, executables. Cross-platform.
This is meant to be used in command-line tools and scripts, not in the browser.
If you need this for Electron, use shell.openPath()
instead.
This package does not make any security guarantees. If you pass in untrusted input, it's up to you to properly sanitize it.
- Actively maintained.
- Supports app arguments.
- Safer as it uses
spawn
instead ofexec
. - Fixes most of the original
node-open
issues. - Includes the latest
xdg-open
script for Linux. - Supports WSL paths to Windows apps.
$ npm install open
const open = require('open');
// Opens the image in the default image viewer and waits for the opened app to quit.
await open('unicorn.png', {wait: true});
console.log('The image viewer app quit');
// Opens the URL in the default browser.
await open('https://sindresorhus.com');
// Opens the URL in a specified browser.
await open('https://sindresorhus.com', {app: {name: 'firefox'}});
// Specify app arguments.
await open('https://sindresorhus.com', {app: {name: 'google chrome', arguments: ['--incognito']}});
It uses the command open
on macOS, start
on Windows and xdg-open
on other platforms.
Returns a promise for the spawned child process. You would normally not need to use this for anything, but it can be useful if you'd like to attach custom event listeners or perform other operations directly on the spawned process.
Type: string
The thing you want to open. Can be a URL, file, or executable.
Opens in the default app for the file type. For example, URLs opens in your default browser.
Type: object
Type: boolean
Default: false
Wait for the opened app to exit before fulfilling the promise. If false
it's fulfilled immediately when opening the app.
Note that it waits for the app to exit, not just for the window to close.
On Windows, you have to explicitly specify an app for it to be able to wait.
Type: boolean
Default: false
Do not bring the app to the foreground.
Type: boolean
Default: false
Open a new instance of the app even it's already running.
A new instance is always opened on other platforms.
Type: {name: string | string[], arguments?: string[]} | Array<{name: string | string[], arguments: string[]}>
Specify the name
of the app to open the target
with, and optionally, app arguments
. app
can be an array of apps to try to open and name
can be an array of app names to try. If each app fails, the last error will be thrown.
The app name is platform dependent. Don't hard code it in reusable modules. For example, Chrome is google chrome
on macOS, google-chrome
on Linux and chrome
on Windows. If possible, use open.apps
which auto-detects the correct binary to use.
You may also pass in the app's full path. For example on WSL, this can be /mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe
for the Windows installation of Chrome.
The app arguments
are app dependent. Check the app's documentation for what arguments it accepts.
Type: boolean
Default: false
Allow the opened app to exit with nonzero exit code when the wait
option is true
.
We do not recommend setting this option. The convention for success is exit code zero.
An object containing auto-detected binary names for common apps. Useful to work around cross-platform differences.
const open = require('open');
await open('https://google.com', {
app: {
name: open.apps.chrome
}
});
