ecmascript 6 - Babel 6 changes how it exports default -


before, babel add line module.exports = exports["default"]. no longer this. means before do:

var foo = require('./foo'); // use foo

now have this:

var foo = require('./foo').default; // use foo

not huge deal (and i'm guessing should have been along). issue have lot of code depended on way things used work (i can convert of es6 imports, not of it). can give me tips on how make old way work without having go through project , fix (or instruction on how write codemod pretty slick).

thanks!

example:

input:

const foo = {} export default foo

output babel 5

"use strict";  object.defineproperty(exports, "__esmodule", {   value: true }); var foo = {}; exports["default"] = foo; module.exports = exports["default"];

output babel 6 (and es2015 plugin):

"use strict";  object.defineproperty(exports, "__esmodule", {   value: true }); var foo = {}; exports["default"] = foo;

notice difference in output module.exports = exports["default"].

edit

you may interested in blogpost wrote after solving specific issue: misunderstanding es6 modules, upgrading babel, tears, , solution

you can use this plugin old export behavior back.

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
