Carlo provides your Node application with the rich rendering capabilities powered by the Google Chrome browser.
With Carlo, you can create hybrid applications that use Web stack for rendering and Node for capabilities:
- For Node applications, you can visualize dynamic state of your Node app using web rendering stack
- For Web applications, you can expose additional system capabilities accessible from Node
- Carlo locates Google Chrome installed locally
- Launches it and establishes connection to Chrome over the process pipe
- Exposes high level API for rendering in Chrome in Node environment
- Carlo is based on the Puppeteer project
To use Carlo in your project, run:
npm i carlo
# or "yarn add carlo"Note: Carlo requires at least Node v7.6.0.
Example - Visualize local environment:
Save file as example.js
const carlo = require('carlo');
(async () => {
const app = await carlo.launch();
app.serveFolder(__dirname);
await app.exposeFunction('env', _ => process.env);
await app.load('example.html');
})();Save file as example.html
<script>
async function run() {
const data = await env();
for (const type in data) {
const div = document.createElement('div');
div.textContent = `${type}: ${data[type]}`;
document.body.appendChild(div);
}
}
</script>
<body onload="run()">Execute script on the command line
