Handles imports and exports, and creates an index.js file that contains the webpack util functions and calls the entry module. 3 | 4 | Currently only works on some (older?) versions of webpack, if you have an example script using a different version create an issue. 5 | 6 | ## Example 7 | Script packed with webpack 8 | ```js 9 | !function(a0) { 10 | var b0 = {}; 11 | function c0(d0) { 12 | if (b0[d0]) return b0[d0].exports; 13 | var e0 = b0[d0] = {}; 14 | b0[d0].i = d0; 15 | b0[d0].l = !1; 16 | b0[d0].exports = {}; 17 | return a0[d0].call(e0.exports, e0, e0.exports, c0), e0.l = !0, e0.exports; 18 | } 19 | c0.m = a0, c0.c = b0, c0.d = function(f0, g0, h0) { 20 | c0.o(f0, g0) || Object.defineProperty(f0, g0, { 21 | 'enumerable': !0, 22 | 'get': h0 23 | }); 24 | }, c0.r = function(i0) { 25 | 'undefined' != typeof Symbol && Symbol.toStringTag && Object.defineProperty(i0, Symbol.toStringTag, { 26 | 'value': "Module" 27 | }), Object.defineProperty(i0, "__esModule", { 28 | 'value': !0 29 | }); 30 | }, c0(c0.s = 1); 31 | }([function(s0, t0, u0) { 32 | function v0(x0) { 33 | console.log(x0); 34 | } 35 | t0.default = v0; 36 | }, function(y0, z0, a1) { 37 | a1.r(z0); 38 | var b1 = a1(0).default; 39 | var c1 = 'Hello World'; 40 | b1(c1); 41 | }]); 42 | ``` 43 | 44 |
45 | After unpacking, two modules (module0.js and module1.js) are created along with an index.js file that contains some utility functions used and calls the entry module.
