How to enable support for old vuejs browsers?

Question

webpack

I am using vue3 in a project. I need support for older browsers, namely chrome 49. When the project is launched in chrome 49, an error occurs - syntax error unexpected token.
Swears on the spread operator.

In babel.config.js the @babel/plugin-proposal-object-rest-spread plugin is enabled but seems to be ignored...

My babel.config.js

module.exports = {
  "presets": ["@vue/cli-plugin-babel/preset"],
  "plugins": 
};

Answer 1

How did it happen so well that Proxy appeared in chrome 49...
And so, do you have a .browserslistrc file? If so, is it stated there that chrome 49?
Polyfills and all that are set based on this file.
