I met the same problem. And while webpack4+babel7 babel.config.js ``` module.exports = { presets: [["@vue/app", { modules: "commonjs" }]], plugins: ["add-module-exports"] }; ``` module.js ``` const a = 1 const...
@ljharb then what has `babel-plugin-add-module-exports` done? Something happens when I publish a module on npm and then import it from `node_modules`.
@ljharb well, I just forget to **rebuild my module**. Acturally, `babel-plugin-add-module-exports` works well and it removes `.default` that what exactly I want. Now ``` import { a } from "module"...
```js // store.js export const todoListTypeState = atom({ key: "todoListTypeState", default: "snack", }); export const todoListState = atom({ key: "todoListState", default: [ { type: "snack", content: "cake" }, { type:...
I really need this.
In fact, `NoPanClassName` is added to node by default so panning does not allowed on nodes. ```js // src/components/Nodes/wrapNode.tsx const nodeClasses = cc([ 'react-flow__node', `react-flow__node-${type}`, noPanClassName, // here className, {...
