How to launch a browser from the a Node.js command line script?
To launch a browser from the a Node.js command line script, we can use the open package.
To install it, we run
npm install --save open
Then we use it by writing
const open = require("open");
(async () => {
await open("unicorn.png", { wait: true });
await open("https://example.com");
await open("https://example.com", { app: "firefox" });
await open("https://example.com", {
app: ["google chrome", "--incognito"],
});
})();
to call open with a file path with
await open("unicorn.png", { wait: true });
We set wait to true to wait for the file to open.
Also, we can call it with a URL with
await open("https://sindresorhus.com");
to open the browser with the URL.
We specify the app option to set the program to open.
Also, we can pass in command line arguments for the app being opened with
await open("https://sindresorhus.com", {
app: ["google chrome", "--incognito"],
});
