babel seems to ignore .browserslistrc

Bug Report

Current Behavior Babel is not compiling code as expected (even const / let stays in code). I am using following CLI command: watchify main.js -t babelify -o build/main.js

Input Code

• REPL or Repo link if applicable:

import 'regenerator-runtime/runtime';
const ytdl = require('ytdl-core');

ytdl.getInfo("YySiE8DsQ0M").then(function(value) {
  // execution
  console.log(value)
}, function(reason) {
  // refuse
  console.log(reason)
});

Expected behavior/code I do expect that babel should transform code to ie8 - compatible (es5)

Babel Configuration (babel.config.js, .babelrc, package.json#babel, cli command, .eslintrc)

• Filename: babel.config.js

module.exports = {
    presets : [
        [
            "@babel/preset-env"
        ]
    ]
}

• Filename: .browserslistrc

IE 8 # sorry

I have also tried .babelrc:

• Filename .babelrc

{
    "presets": [
        ["@babel/preset-env", {
            "useBuiltIns": "entry",
            "targets": {
                "browsers": ["ie >= 7"]
            }
        }]
    ]
}

I’ve reported a similar issue in #11651 but it is not related to node_modules.

@ak1987 Try this. First:

npm install --save-dev @babel/preset-env @babel/transform-runtime npm install --save @babel/runtime-corejs3

and try this config: babel.config.json:

{
  "presets": [
    ["@babel/preset-env", {
      "targets": {
        "browsers": ["ie >= 8"]
      }
    }]
  ],
  "plugins": [
    ["@babel/transform-runtime", {
      "corejs": 3,
      "absoluteRuntime": true
    }]
  ]
}

and this:

var fs = require("fs");
var browserify = require("browserify");

(async ()=>{
  await browserify({ entries: ["main.js"] })
  .transform("babelify", {
    global: true,
  })
  .bundle()
  .pipe(fs.createWriteStream("bundle.js"));
})();
