This .tern-project config works for me:

  {
    "libs": [
      "browser"
    ],
    "plugins": {
      "node": {},
      "es_modules": {}
    }
  }

Your project files must have "correct" format, e.g. require('relative_path') for imports and module.exports/exports for exports (or es6 import and export). Example for AMD format (requireJS) can be found here - http://ternjs.net/doc/manual.html#configuration
