Transpile node_modules to ES5 during meteor building, is it possible?

Hi, I have installed ecmascript package and also I defined a list of some packages in node_modules, which needs to be transpiled to ES5, because for example spread operator makes me problem on older browsers.

I updated meteor section inside package.json, by the meteor documentation to transpile some of packages to ES5, but It not helped. Probably, It’s not working. What I’m doing wrong and how you transpiling node_modules dependencies to ES5, to make compatible your meteor apps with older browsers?


  "meteor": {
    "mainModule": {
      "client": "client/main.ts",
      "server": "server/main.ts"
    },
    "testModule": "tests/custom/main.ts",
    "nodeModules": {
      "recompile": {
        "@popperjs/core": [
          "legacy"
        ],
        "bootstrap": [
          "legacy"
        ],
        "bootstrap-daterangepicker": [
          "legacy"
        ],
        "swiper": [
          "legacy"
        ]
      }
    }
  },

Thanks a lot.
