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)
})
}
