Add “proposal-object-rest-spread” plugin to babel.config.js to fix Microsoft Edge error SCRIPT1028

Question

EDIT: This issue seems to be fixed with the new beta of Microsoft Edge Chromium. (January 18, 2020)

I need to add this Babel plugin to babel.config.js to get rid of the Microsoft Edge Browser error

SCRIPT1028: Expected identifier, string or number

I installed the latest packages and added them to package.json. Below is what I tried but it doesn't transform the code after running npm run build :

babel.config.js

require("@babel/core").transform("code", {});

module.exports = {
  presets: ["@vue/app"],
  plugins: ["@babel/plugin-proposal-object-rest-spread"]
};

How to setup the Babel plugin to transform the code correctly?

EDIT: Error Screenshot - EDGE INSIDER 18 points to this piece of code:

Answer 1

since I cannot try out the code that you are dealing with to check, I would suggest to use the following babel config as mentioned in the library config:

  plugins: [["@babel/plugin-proposal-object-rest-spread", { "loose": true, "useBuiltIns": true }]]

Answer 2

babel.config.js should export a function and should be at the root of your project.

Your configuration should be similar to this

module.exports = function(api) {
    api.cache(true);

    const presets = ['@vue/app'];
    const plugins = ['@babel/plugin-proposal-object-rest-spread'];
    // Or try this
    // const plugins = [['@babel/plugin-proposal-object-rest-spread', { loose: true, useBuiltIns: true }]];

    return {
        presets,
        plugins,
    };
};
