Hmm, an error occurs when importing gosling.js.

Code:

const { validateGoslingSpec, GoslingComponent } = require("gosling.js");

Error Message:

Module not found: Error: Package path . is not exported from package /Users/sehilyi/Documents/hms-dbmi/gosling/gosling-website/node_modules/gosling.js (see exports field in /Users/sehilyi/Documents/hms-dbmi/gosling/gosling-website/node_modules/gosling.js/package.json)

Package.json:

"exports": {
  ".": {
    "types": "./dist/src/index.d.ts",
    "import": "./dist/gosling.js"
  },
  "./utils": {
    "types": "./dist/src/exported-utils.d.ts",
    "import": "./dist/utils.js"
  },
  "./compiler": {
    "types": "./dist/src/exported-compiler.d.ts",
    "import": "./dist/compiler.js"
  }
},

I can confirm that all files exist as specified in the package.json.
