This example illustrates how to specify chunk name in require.ensure() and import() to separated modules into separate chunks manually.
import("./templates/foo" /* webpackChunkName: "chunk-foo" */ ).then(function(foo) {
console.log('foo:', foo);
})
require.ensure([], function(require) {
var foo = require("./templates/foo");
console.log('foo:', foo);
}, "chunk-foo1");
var createContextVar = "r";
import("./templates/ba" + createContextVar /* webpackChunkName: "chunk-bar-baz" */ ).then(function(bar) {
console.log('bar:', bar);
})
templates/
- foo.js
- baz.js
- bar.js
All templates are of this pattern:
var foo = "foo";
export default foo;
