Try it this way:
import React from 'react'
import { FlowRouter } from 'meteor/ostrio:flow-router-extra'
import {mount} from 'react-mounter'
FlowRouter.route('/terms', {
name: 'terms',
action(params, queryParams) {
import('/imports/client/terms').then((Terms) => { // -> with or without {} brackets
console.log(Terms); // <- What its output?
mount(Layout, {
content: <Terms />,
})
})
}
})
