There is no such extension, but you can implement it on your own.
Here is a booting server.js of jsreport
const jsreport = require('jsreport')() if (process.env.JSREPORT_CLI) { module.exports = jsreport } else { jsreport.init().then(() => { // expose a URL that can be used to trigger reload jsreport.express.app.get('/api/reload', (req, res) => { jsreport.documentStore.provider.reload() .then(() => res.send('done')) .catch((e) => res.send(e.message)) }) }).catch((e) => { console.trace(e) process.exit(1) }) }
